[0003] Old analog television and projectors cannot be disposed of into
landfills. Instead, recycling of electronic waste is a sustainable habit that can be
adopted with low cost reconfiguration of existing products. Therefore there is
need in the art to develop a device that can reconfigure old analog television,
monitors and projectors into automated display devices that can be used to display
images and videos as electronic photo frames. High definition digital signal to
standard definition analog signal converters are reported in existing literature.
Another device discloses a composite video converter that can upscale the output
video resolution. Conversion steps for old laptops into electronic photo frame also
exist in the current literature. However, none of the existing disclosures provide a
controller for automatic reconfiguration of the analog display unit.
[0004] The proposed device discloses a controller for reconfigurable analog
display units. The controller can be configured to perform a set of operations based on user input, the set of operations determining the sequence, repetition rate, duration and mode of transition of the selected digital multimedia files stored in one or more portable multimedia storage coupled to the proposed device. The proposed device provides an easy, low cost solution for recycling old electronic television, monitors and display units. The proposed solution is not only economic but also good for the environment.
