Abstract: The present invention relates to a system for measuring session effectiveness of the presenter and a receiver’s engagement of a particular session on an online system based on audio data, video data and whiteboard usage of a presenter and the receiver is provided. In achieving this, an audio data, video data and whiteboard usage data may be recorded and can be stored for future review purposes. Further to review every session automatically, the session can be analyzed based on the available audio data and whiteboard usage data. From that multiple characteristics/parameters can be measured, which can be analyzed further to obtain a session effectiveness score. The session can be broadcasted from a primary presenter and multiple or single receivers. Further, the whiteboard usage text and images or shapes can be transferred to the receiver in a pixel coordinate codec format in order to reduce the bandwidth, space and transmission time.
