The video ports are also capable of capturing/displaying RAW data. The video port peripherals follow video standards such as BT.656 and SMPTE296. 6.11.1 Video Port Device-Specific Information The devices have five video port peripherals. The video port peripheral can operate as a video capture port, video display port, or as a transport channel interface (TCI) capture port. The port consists of two channels: A and B. A 5120-byte capture/display buffer is splittable between the two channels. The entire port (both channels) is always configured for either video capture or display only. Separate data pipelines control the parsing and formatting of video capture or display data for each of the BT.656, Y/C, raw video, and TCI modes. For video capture operation, the video port may operate as two 8-bit channels of BT.656 or raw video capture; or as a single channel of 8-bit BT.656, 8-bit raw video, 8-bit Y/C video, 16-bit raw video, or 8-bit TCI. For video display operation, the video port may operate as a single channel of 8-bit BT.656; or as a single channel of 8-bit BT.656, 8-bit raw video, 8-bit Y/C video, or 16-bit raw video. It may also operate in a two channel 8-bit raw mode in which the two channels are locked to the same timing. Channel B is not used during single channel operation. For more detailed information on the video port peripherals, see the TMS320DM647/DM648 Video Port User's Guide (literature number SPRUEM1). 6.11.2 Video Port Peripheral Register Description(s) Table 6-48.
