YUV422 to YUV420 Color Space Conversion on FPGA

Abhilash R. Namboodiri, Sujata D. Badiger, Rajagopal Narayanasamy

Abstract


YUV is a popular color encoding system similar to the popular RGB variant but is less data intensive. YUV stores only the difference among the chrominance values and absence of data bytes can be represented as a grayer image resulting in reduced data consumption. YUV422 (YCbCr) forms the standard video format used in various broadcasting technologies and standards. However, at high resolutions and higher frame rates it needs to be converted to YUV420 format which is similar but not as data intensive. This conversion is realized in Verilog and implemented on an FPGA which converts the video data for real-time applications.
