Abstract:
1. A method for transmission of a plurality of analog videos carried by a plurality of analog broadcasting channels through a digital broadcasting medium, the method comprising: spatially multiplexing a first set of video frames of a first set of analog videos to form a first array of multiplexed video frames; spatially multiplexing a second set of video frames of a second set of analog videos to form a second array of multiplexed video frames, wherein the first array of multiplexed video frames and the second array of multiplexed video frames are formed upon reducing a frame rate of each analog video to a half frame rate; temporally multiplexing the first array of multiplexed video frames with the second array of multiplexed video frames; multiplexing header information related to the first and second set of video frames in a spatial domain and a temporal domain to generate a bundled multiplexed video content, wherein the bundled multiplexed video content comprises at least a single dimensional barcode or a two dimensional barcode, and wherein the single dimensional barcode and the two dimensional barcode indicate a spatial and temporal map for the first set of analog videos and the second set of analog videos; encoding the bundled multiplexed video content to generate a digital video elementary stream; generating a digital transport video stream from the generated digital video elementary stream; and transporting the generated digital transport stream through a digital broadcasting medium.
