A TCP (Transmission Control Protocol)/IP (Internet Protocol) 130 executes the processing of connecting the communication board 35 to the network 6, furnishes an E-mail received from the personal computer 7 through the network 6 to the E-mail program 106 and transmits the E-mail sent from the E-mail program 106 to the personal computer 7. In the following, explanation on the speech is omitted. Fig.9 shows an illustrative structure of the AV contents. In the content database 122, recorded in the HDD 31, there are recorded attributes of the respective AV contents. In an AV content attribute record 152-1, recorded in the content database 122, there are stored data, such as name, ID (identification data), date and time of formulation, date and time of change, date and time of recording, channel name, recording mode, state, term of validity, shown by date and time, setting of the mistaken deletion, presence or absence of errors, two-dimensional bar code and memo, as attributes of the AV contents 151-1. In an AV content attribute record 152-2, recorded in the content database 122, there are stored data, such as name, ID, date and time of formulation, date and time of change, date and time of recording, channel name, recording mode, state, term of validity, setting of the mistaken deletion, presence or absence of errors and memo, as attributes of the AV contents 25 151-2. The recording mode data stored in the AV content attribute record 152-1 indicate that the moving picture data files 161-1-1 to 161-1-3 are one of high quality, standard and video CD compatible, which video CD compatible specifies that the picture data are of the MPEG-1 system. On the other hand, the status data stored in the AV content attribute record 152-1 indicate that the AV content attribute record 151-1 is in an reservation queue, in recording state, in the recording and/or reproducing state, that is in the state of recording data and reproducing recorded picture data, in the non-reproducing state, in the reproducing state or in the replay end state. The error indicates the states of the AV content attribute record 151-1, such as the personal computer 1 malfunctioning during recording, recording aborted partway, recording state during recording being bad such that input signals from the antenna 2 are not reproduced, or partial dropout of the moving picture file 161-1-1. As for the setting of the term of validity and the setting for inadvertent deletion, neither one is set, or one of them is set, while it does not occur that both are set simultaneously. The recording mode data stored in the AV content attribute record 152-2 indicate that the moving picture data files 161-2-1 to 161-2-3 are one of high quality, standard and video CD compatible. On the other hand, the status data stored in the AV content attribute record 152-2 indicate that the AV content attribute record 151-2 -L€- is in the reservation queue, in recording state, in the recording and/or reproducing state, in the non-reproducing state, in the reproducing state or in the replay end state. The AV content attribute record 151-1 is made up of moving picture data files 161-1-1 to 161-1-3, recorded on the HDD 31, and of moving picture data files 162-1-1 to 162-1-3, recorded on the HDD 31. In the moving picture data files 161-1-1 to 161-1-3, there are stored picture data of the MPEG system. The picture corresponding to the picture data stored in the leading end of the moving picture data file 161-1-2 is consecutive to a picture corresponding to picture data stored in the trailing end of the moving picture data file 161-1-1. Similarly, the picture corresponding to the picture data stored in the leading end of the moving picture data file 161-1-3 is consecutive to a picture corresponding to picture data stored in the trailing end of the moving picture data file 161-1-2. In a still picture data file 162-1-1, picture data corresponding to a still picture converted from a scene change picture of picture data stored in the moving picture data file 161-1-1 and data on the scene change time are stored. In a still picture data file 162-1-2, picture data corresponding to a still picture converted from a scene change picture of picture data stored in the moving picture data file 161-1-2 and data on the scene change time are stored. In a still picture data file 162-1-3, picture data corresponding to a still picture converted from a scene change picture of picture data stored in the moving picture data file 161-1-3 and data on the scene change time are stored. -2-7- The AV contents 151-2 are made up of the moving picture data files 161-2-1 to 161-2-2 and still picture data files 162-2-1 and 162-2-2, and are similar to the AV contents 151-1. Therefore, the AV contents 151-2 are not explained specifically. If there is no necessity of demarcating the AV contents 151-1 and the AV contents 151-2 from each other, these are simply termed an AV contents 151. If there is no necessity of demarcating the AV contents attribute record 152-1 and the AV contents attribute record 152-2 from each other, these are simply termed an AV contents attribute record 152. If there is no necessity of demarcating the moving picture data files 161-1-1 to 161-1-3 from one another, or if there is no necessity of demarcating the moving picture data files 161-2-1 or 161-2-2 from each other, these are also termed a moving picture data file 161. In addition, if there is no necessity of demarcating the still picture data files 162-1-1 to 162-1-3 or the still picture data files 162-2-1 or 162-2-2 from one another, these are simply termed a still picture data file 162. The picture the recording and/or reproducing program 101 displayed on the CRT 30 of the personal computer 1 is hereinafter explained. Fig. 10 shows a picture displayed on the CRT 30 of the personal computer 1 when the picture recording operation is possible. In a picture recording window 181 are set a channel for recording, a recording mode etc. When the picture recording is started, the recording and/or reproducing program 101 sets the operation of the tuner 54 of the picture processing board 34 or -2-S- the MPEG encoder 58 of the picture processing board 34, based on the setting of the picture recording window 181, to generate pre-set AV contents 151 and the AV contents attribute record 152 for recording on the HDD 31. When the picture recording window 181 is selected and active, a picture recording button 182 and a recording stop button 183 are both active to enable the operation. That is, if the picture recording window 181 is selected and active, the recording and/or reproducing program 101 starts and halts picture recording when a recording button 182 is clicked and a stop button 183 is clicked, respectively. If the picture recording window 181 is selected and active, a playback button 184 and a pause button 185 are non-active, such that the recording and/or reproducing program 101 is not in operation even when the playback button 184 or the pause button 185 is clicked, respectively. Fig. 11 illustrates a picture displayed on the CRT 30 of the personal computer 1 when the recording and/or reproducing program 101 has started picture recording. The picture recording window 181 displays the time elapsed as from start of picture recording and the current time in addition to the recording channel and the recording mode. When the recording is started, the recording button 182 is changed to a recording time change button 191. The recording time is changed whenever the recording time change button 191 is clicked. A picture displayed when a specified AV contents 151 or AV contents 121 are -*. letter code is to be limited to ascii. The step (STEP) can be abbreviated. Clockadjusrt It means a field scheduled to be added. If TVPI is to be acquired over the network, the time on a timepiece of a server furnishing the TVPI is to be notified. The server time is to be stated "yyyymmddhhmmss" (for example, 20 o'clock, 6 minute 9 second of September 16,1999 - 19990916200609. The letter code is limited to ascii. This enables the enclosed timepiece to be corrected, while enabling the latest acquisition time in case plural overlapping reserves are entered. Url: A field scheduled to be added. It states URL. Plural fields can be stated. By kicking this URL to the browser in replay, it is possible to browse a page interlocked to a program. Url-begin: Url-end: A field scheduled to be added. If this field is stated next to the [url:] field, it sets the time period the URL remains effective. The offset from the leading end is stated by "hhmmss". The letter code is limited to ascii. -5L Similarly, on line 6 of the recording reservation data of the v-calendar system, there is stated data specifying date and time of recording termination. For example, in "DTEND: 19990601T214500Z" in Fig.21, "19990601" between the "DTEND:" and "T" denotes that the recording end date is June 1,1999 and "214500" between "T" and "Z" denotes that the recording end time is 21 hour 45 minute 00 second. Similarly, on line 7 of the recording reservation data of the v-calendar system, there is stated, next to "LOCATION", data specifying the recording channel. For example, "LOCATION: 1" of Fig.21 indicates recording of one channel. On line 9 of the recording reservation data of the v-calendar system, there is stated, next to "DESCRIPTION" the name of the program to be recorded. In Fig.21, "DESCRIPTION: close up ancient times" denotes that the name of the program to be recorded is the "closeup ancient times". In this manner, by the user of the personal computer 7 transmitting an E-mail, having attached thereto the E-mail, having attached thereto the embodiment reservation data, the user of the personal computer 1 is able to record the pre-set program readily. Referring to the flowchart of Fig.22, the processing for recording reservation in case the reservation recording setting program 104 is executed using the WWW browser 106 is explained. At step Sll, the WWW browser 106 verifies whether or not the recording reservation data has been transmitted from the server 7. If it is verified that the recording reservation data has not been transmitted from the server (/(?-. 7, the WWW browser 106 reverts to step S12 to repeat the processing until the recording reservation data has been transmitted from the server 7. If it is verified at step S12 that the recording reservation data has been transmitted from the server 7, the WWW browser 106 advances to step S13 where it receives the recording reservation data to furnish the received recording reservation data to the reservation recording setting program 104. At step sl4, the reservation recording setting program 104 executes the processing for channel setting based on the supplied recording reservation data. The processing for channel setting will be explained subsequently in detail with reference to Fig.23. At step S15, the reservation recording setting program 104 displays a message certifying to the reservation setting in e.g., a window shown in Fig.15. At step S16, the reservation recording setting program 104 records AV contents in reservation queue, inclusive of a moving picture data file 161 which has secured a pre-set area of the HDD 31, based on the supplied recording reservation data. At step S17, the reservation recording setting program 104 causes the contents database 152 to generate the AV contents attribute record 152, corresponding to the AV contents in reservation queue, based on the supplied recording reservation data, to terminate the processing. In this manner, the reservation recording setting program 104 and the WWW browser 106 is able to execute the reservation of recording of a pre-set program So- speedily. The processing for channel setting, corresponding to step S14 of Fig.22, is now explained with reference to the flowchart of Fig.23. At step S21, the reservation recording setting program 104 reads-in the recording reservation data furnished from the WWW browser 106. At step S22, the reservation recording setting program 104 reads out the character string next following "station" of the recording reservation data. At step S23, the reservation recording setting program 104 reads out a character string of a pre-set channel name from a channel conversion file. At step S24, the reservation recording setting program 104 verifies whether or not the character string next following "station" is coincident with the character string of a pre-set channel name. If it is verified that character string next following "station" is coincident with the character string of the pre-set channel name, the reservation recording setting program 104 proceeds to step S25 to set a channel corresponding to the character string of the pre-set channel name. At step S26, the reservation recording setting program 104 sets channel demonstration corresponding to the channel as set at step S25 (that is sets data for channel demonstration and data for channel name demonstration) to terminate the processing. If it is verified at step S24 that character string next following "station" is not coincident with the character string of the pre-set channel name, the reservation -yTI- -5* recording setting program 104 proceeds to step S27 to verify whether or not the totality of the character strings of the channel names have been read out. If it is verified that the totality of the character strings of the channel names have been read out, the reservation recording setting program 104 proceeds to step S28 to display a message reading that no channel has been found on a CRT 30 to terminate the processing. If it is verified at step S27 that the totality of the character strings of the channel names have not been read out, the reservation recording setting program 104 proceeds to step S29 to read out a character string of an other channel name. The reservation recording setting program 104 then reverts to step S24 to repeat the processing for verifying the possible character string coincidence. As described above, the reservation recording setting program 104 is able to set a pre-set channel despite certain ambiguity in the character string next following the "station" of the recording reservation data. Referring to the flowchart of Fig.24, the processing for furnishing recording reservation data by a server 7 in case the Web server program is loaded on a RAM 83 and a CPU 81 executes a Web server program, is now explained. At step S51, the Web server program receives a message from the personal computer 1-1 based on e.g., the HTTP. At step S52, the Web server program verifies whether or not a message received from the personal computer 1-1 is a message requesting pre-set recording reservation data. If it is verified that the message received from the -£*_- personal computer 1-1 is a message requesting pre-set recording reservation data, the Web server program proceeds to step S53 to transmit recording reservation data corresponding to the message to the personal computer 1-1 to terminate the processing. If it is verified at step S52 that the message received from the personal computer 1-1 is not a message requesting pre-set recording reservation data, the step S53 is skipped to terminate the processing. In this manner, the server 7 furnishes pre-set recording reservation data to the personal computer 1-1. The processing of transmitting recording reservation data by the E-mail program of the personal computer 7-1 is explained with reference to the flowchart of Fig.25. At step Sill, the E-mail program of the personal computer 7-1 attaches recording reservation data, previously generated and recorded, to an E-mail. At step SI 12, the E-mail program of the personal computer 7-1 transmits the E-mail, having the recording reservation data appended thereto, to the personal computer 1 over the network 6 to complete the processing. As described above, the E-mail program of the personal computer 7-1 is able to transmit the recording reservation data to the personal computer 1. It is possible for the E-mail program to attach the recording reservation data appended to the E-mail received from a personal computer 7-2 at step Sill to its E-mail. The processing of reception of the recording reservation data by the E-mail S3- program 106 of the personal computer 1 is explained with reference to the flowchart of Fig. 18. At step S121, the E-mail program 106 of the personal computer 1 receives an E-mail, having attached thereto the recording reservation data received from the personal computer 7-1 or 7-2, over the network 6. At step SI22, the E-mail program 106 of the personal computer 1 records the recording reservation data, attached to the E-mail, in the RAM 23 or in the HDD 31, to terminate the processing. It is possible for the E-mail program 106 to send the recording reservation data appended to the E-mail at step SI22 directly to the reservation recording setting program 104. In this manner, the E-mail program 106 of the personal computer 1 is able to receive the recording reservation data. Referring to the flowchart of Fig.27, the processing of recording reservation by the reservation recording setting program 104 of the personal computer 1 is hereinafter explained. At step S131, the reservation recording setting program 104 reads out the recording reservation data recorded on the RAM 23 or on the HDD 31. If, at step S32, the E-mail program 106 directly sends the recording reservation data, attached to the E-mail, to the reservation recording setting program 104, the step S51 can be omitted. At step S132, the reservation recording setting program 104 records the AV contents 151 in an reservation queue, including the moving picture data file 161 which has secured a pre-set area of the HDD 31, based on the read-out recording --5-7- reservation data. At step S13, the reservation recording setting program 104 causes a content database 152 to generate an AV content attribute record 152, corresponding to the AV contents 151 in reservation queue, based on the recording reservation data, to complete the processing. The reservation recording setting program 104 of the personal computer 1 executes the recording reservation processing, as described above. Referring to the flowchart of Fig.28, the processing for the reservation recording in case the reservation monitoring program 105 resident in the RAM 23 is executed by the CPU 21 is now explained. At step S71, the reservation monitoring program 105 reads out the current time from the RTC, not shown. At step S72, the AV contents attribute record 152 corresponding to the AV contents 151 in a pre-set reservation queue is read out. At step S73, the reservation monitoring program 105 compares the current time to the recording start time contained in the AV contents attribute record 152 to check whether or not the reservation recording is to be started. If it is verified that the reservation recording should be started, the program moves to step S74 to start the recording. The reservation monitoring program 105 overwrites data of the picture generated in the picture processing board 34 on the previously recorded data file 161. At step S75, the reservation monitoring program 105 reads out the current time from the RTC, not shown. At step 76, the reservation monitoring program 105 compares the current time to the recording end time contained in the AV contents -63~ ^S4 attribute record 152 to check whether or not the recording reservation is to be terminated. If it is verified that the recording reservation is not at an end, the recording is continued so that the program moves to step S75 to repeat the processing of verifying the end time. If it is verified at step 76 that the recording reservation is to be terminated, the program moves to step S77 where the reservation monitoring program 105 changes data of the AV contents attribute record 152 to a pre-set value. The recording then comes to a close to terminate the processing. If it is verified at step S73 that the recording reservation is not to be started, the program moves to step S78 where the reservation monitoring program 105 verifies whether or not the AV contents attribute record 152 corresponding to the entire AV contents 151 in the reservation queue has been read out in its entirety. If it is verified that the AV contents attribute record 152 corresponding to the entire AV contents 151 in the reservation queue has not been read out in its entirety, the program moves to step S79, where the reservation monitoring program 105 reads out the AV contents attribute record 152 corresponding to another AV contents 151 in the reservation queue. The program then reverts to step S73 to repeat the processing for decision as to starting the recording reservation. If it is verified at step S78 that the AV contents attribute record 152 corresponding to the AV contents 151 in the reservation queue has been read out in its entirety, there lack AV contents 151 that are to be recorded by reserve, so that -S<~ processing comes to a close. As described above, the reservation monitoring program 105 executes the recording reservation based on the AV contents 151 in the reservation queue and the current time. The above-described sequence of operations can be executed by the hardware, however, it can also be executed by software. If the sequence of operations is executed by the software, the program constituting the software is installed in a computer built into a hard disc recorder, as a dedicated hardware, or in e.g., a ubiquitous computer in which a variety of programs are installed to execute variable functions. The processing of transmitting recording reservation datably an E-mail program of the personal computer 1-2 is explained with reference to the flowchart of Fig.30. At step S91, the E-mail program of the personal computer 1-2 appends the recording reservation data to the E-mail. The E-mail program transmits the E-mail, having the recording reservation data, appended thereto, to the personal computer 1-1 to terminate the processing. As described above, the E-mail program is able to transmit the recording reservation data to the personal computer 1-1. The personal computer, on receipt of the E-mail, having the recording reservation data, appended thereto, is able to make the reservation for recording by the processing similar to that explained with reference to the flowchart of Fig.22. ~si~ r Referring to Fig.29, a medium used in installing a program for executing the above-described sequence of operations on a computer to set a state executable by the computer is explained, taking a case wherein the computer is a ubiquitous personal computer as an example. The program can be furnished in a pre-installed state on a hard disc 302, as a recording medium enclosed in a personal computer 301, corresponding to a hard disc enclosed in the hard disc drive 31 of Fig.3, or in a pre-installed state on a semiconductor memory 303, as shown in Fig.29A. Alternatively, the program can be transiently or permanently stored in a recording medium, such as a floppy disc 311, a CD-ROM (compact disc-read only memory) 312, MO (magneto-optical) disc 313, DVD (digital versatile disc) 314, a magnetic disc 315 or a semiconductor memory 316, and furnished as packaged software, as shown in Fig.29B Moreover, the program can be transmitted over a radio path from a downloading site 321 through an artificial satellite 322 for digital satellite broadcasting to the personal computer 301, or transmitted through a network 331, a local area network or Internet, so as to be stored in the enclosed hard disc 302 in the personal computer 301, as shown in Fig.29. The meaning of the medium in the specification is to be construed broadly to comprise all these mediums. The personal computer 301 has enclosed therein a central processing unit -s§- (CPU) 342, as shown for example in Fig.31. To the CPU 342 is connected an input/output interface 345 over a bus 341. If a command is input via an input unit 347 comprising a keyboard, a mouse etc, through the input/output interface 345, the CPU 342 executes the program stored in a read-only memory (ROM) 343 corresponding to the semiconductor memory 303 of Fig.21A. Alternatively, the CPU 342 loads a program on a RAM (random-access memory) 344 to execute the program. This program is pre-stored on the hard disc 302, or is transmitted from an artificial satellite 322 or a network 331, received by a communication unit 348 and subsequently installed on a hard disc 302, or is read out from the floppy disc 311, CD-ROM 312, DVD 314 or the magnetic disc 315 loaded on a drive 349 so as to be installed on the hard disc 302. The CPU 342 outputs the processing results via e.g., the input interface 345 to a display 346 made up e.g., of a liquid crystal display (LCD). Also, the step of stating the program furnished by the medium may include not only the processing executed chronologically in accordance with a stated sequence but also the processing executed in parallel or separately without being processed chronologically. In the present specification, the system is to be construed as meaning an entire apparatus made up of plural devices. -si- WE CLAIM: 1.
