www.ti.com Video Port 1.1 Video Port The video port peripheral can operate as a video capture port, video display port, or transport channel interface (TCI) capture port. It provides the following functions: • Video capture mode: – Capture rate of up to 80 MHZ. – Two channels of 8-bit digital video input from a digital camera or an analog camera (using a video decoder). Digital video input is in YCbCr 4:2:2 format with 8-bit resolution multiplexed in ITU-R BT.656 format. – One channel of Y/C 16-

www.ti.com Video Port FIFO 1.2 Video Port FIFO The video port includes a FIFO to store data coming into or out from the video port. The video port operates in conjunction with EDMA transfers to move data between the video port FIFO and external or on-chip memory. You can program threshold settings so that EDMA events generate when the video port FIFO reaches a certain fullness (for capture) or goes below a certain fullness (for display). You set up EDMA Channels that are required to service the

www.ti.com Video Port FIFO 1.2.2 Video Capture FIFO Configurations During video capture operation, the video port FIFO has one of four configurations depending on the capture mode. For BT.656 operation, the FIFO is split into channel A and B, as shown in Figure 1-2. Each FIFO is clocked independently with the channel A FIFO receiving data from the VDIN[9-2] half of the bus and the channel B FIFO receiving data from the VDIN[19-12] half of the bus. Each channel's FIFO is further split into Y, Cb,
