The HSMC Quad Video card is based on the Texas Instruments TVP5154 quad video decoder. The analogue video inputs supported by the TVP5154 include composite video and S-video. In general, the video decoder converts the analogue video input signal into digital component data. This data and the associated clocks from the video decoder are sent to the host fpga via the hsmc connector. A pre-scalar is integrated into the device which allows real-time scaling of input video data. The device is controlled using i2c from the fpga.
Video output is based on the Chrontel CH7010B device. This device enables single-link DVI, component analogue and composite analogue video outputs. The device accepts digital, parallel video data and clocking from the host fpga via the hsmc connector. The host fpga is able to configure and monitor the device over an i2c link. A DVI output connector and mini-din output connector is present on the board.
The hsmc quad video daughter card also supports a serial eeprom for FPGA design security. Developers can distribute demonstrations of their IP locked to the hsmc bvdc card. For more information click here.
