Abstract
An Internet based television program delivery server, communicatively coupled to a plurality of television source devices and a plurality of recipient devices, that receives a plurality of Internet protocol television programs, buffers them, converts recipient device selected Internet protocol television programs to preview Internet television programs (having reduced per video frame data size) and transmits the preview Internet protocol television programs to the recipient device, for a short duration, until full scale Internet protocol television programs become available for viewing on the recipient device. A video conversion circuitry built into the Internet based television program delivery server performs the conversion of some of these television video contents to preview television video contents, to compensate for delay in full scale television program delivery during. The conversion itself includes reductions in frame rate, color and pixel resolutions, screen size and aspect ratios such that it produces lower bandwidth Internet protocol television program packets, during channel changing.
