Method and system for transmitting a 1080P60 video in 1080i format to a legacy 1080i capable video receiver without resolution loss
Abstract:
A single progressive 1080P60 side-by-side 3D video or a single progressive 1080P60 2D video is captured for transmission to interlaced receivers such as a legacy 1080i capable video receiver. A video transmitter splits the captured 1080P60 video into a plurality of even-indexed line pictures and odd-indexed line pictures. Lines of the plurality of even-indexed line pictures and odd-indexed line pictures are reassembled to generate two interlaced video sequences such as two 1080i video sequences. The video transmitter compresses the generated two 1080i video sequences, respectively, utilizing different compression algorithms, for example. Pictures that originate from the same one of the plurality of pictures in the captured 1080P60 video may be synchronized for a progressive display at the legacy 1080i capable video receiver. The legacy 1080i capable video receiver may decode the synchronized pictures from the video transmitter so as to restore the captured 1080P60 video for display in progressive format.
