| DEC_BT656 is a digital video decoder with integrated colour-space converter. It's function is to extract the valid pixels from a BT.656 video stream and convert them to 24-bit RGB for subsequent processing. Pixels are extracted from the BT.656 input stream and converted to RGB888 format. Application BT.656 input video capture and processing PAL & NTSC SDTV interlaced format conversion | 概述 | |||||

| ITU-R_BT is a digital video encoder with integrated colour-space converter. The encoder accepts 24-bit RGB pixels from sequential odd and even fields. These pixels are then mapped to the YCbCr colour-space and formatted correctly into a BT output stream. The output of the encoder generates an industry standard ITU-R BT.656 format video stream together with a video_val signal that is asserted with the first valid byte of the output stream.

| Video Frame Buffer | 参考报价 | 无资料 | 300 MHz | 无资料 | |

| VID_FB is a high-speed multi-format video frame buffer that asynchronously samples an input video stream and buffers it in an external memory. Output pixels are read out of the buffer and synchronised to the system clock domain. The VID_FB will automatically adapt to different input and output frame rates. If the input frame rate is too high, then the VID_FB will cleanly drop or 'skip' an input frame. Likewise, if the output frame rate is higher than the input frame rate, then frames will be repeated 3 . The result is a system that seamlessly adapts to the different frame rates at the input and output of the VID_FB.
