Design of TVP5150 controller based on FPGA

Abstract

In this paper, a design of TVP5150 controller based on FPGA (Field Programmable Gate Array) is proposed. This design uses the series of VIRTEX-4 XC4VSX25 chip to control the video decoder TVP5150. FPGA initialized video decoder TVP5150 via IIC bus standard. In order to decode the video data, the input channel, working state and the output data format of TVP5150 should be configured. In this paper, it describes the method of initializing TVP5150 through FPGA based on IIC bus. And then, introduce the format of ITU-R BT.656 of the output video data and the way of extracting the available data from ITU-R BT.656.
