Methods and systems for video format transformation in a mobile terminal having a video display may include converting interleaved YUV 4:2:2 color space video data to YUV 4:2:0 color space video data as the interleaved YUV 4:2:2 color space video data is received. The conversion may use Y, U, and V components in the interleaved YUV 4:2:2 color space video data for a horizontal line of video data. The conversion may also use only a Y component in the interleaved YUV 4:2:2 color space video data for a previous horizontal line or a successive horizontal line of video data. The converted 4:2:0 color space video data may be transferred to memory via, for example, direct memory access. The YUV 4:2:0 color space video data may be transferred to the memory as, for example, 32-bit words.
