This paper describes the design of a multistandard video encoder. The proposed encoder accepts conventional NTSC/PAL video signals. It also processes the PAL-plus video signal which is now popular in Europe. The encoder consists of five major building functions which are letter-box convener, color space converter, digital filters, color modulator, and timing generator. In order to support multistandard video signals, a programmable systolic architecture is adopted in designing various digital filters. Interpolation digital filters are also used to enhance signal-to-noise ratio of encoded video signals. The input to the encoder can be either YCbCr signal or RGB signal. The outputs are luminance(Y), chrominance(C), and composite video baseband(Y+C) signals. The architecture of the encoder is defined by using Matlab program and is modelled by using Verilog-HDL language. The overall operation is verified by using various video signals, such as color bar patterns, ramp signals, and so on The encoder contains 42K gates and is implemented by using 0.6um CMOS process.
