Patent ID: 7688334

Claim:
A method for processing video signals, the method comprising: performing via one or more processors and/or circuits within a video processing device: converting interleaved YUV 4:2:2 color space video data to YUV 4:2:0 color space video data as said interleaved YUV 4:2:2 color space video data is received, said converting comprising: using Y, U, and V components in said interleaved YUV 4:2:2 color space video data for a horizontal line of video data, wherein, for each pixel in said horizontal line: video space information comprises Y component data and only one of U component data or V component data, wherein skipping of one of U component data and V component data is alternated in said horizontal line; and a corresponding missing U component data or V component data is subsequently generated using an immediately neighboring pixel; and using only a Y component in interleaved YUV 4:2:2 color space video data for at least one of a previous horizontal line or a successive horizontal line of video data; and transferring said 4:2:0 color space video data to memory.
