A Systolic Pipelined NTSC/PAL Digital Video Encoder

摘要

This paper describes the design of a multistan- dard video encoder. The proposed encoder accepts conventional NTSC/PAL video signals. The encoder consists of four major building functions which are color space converter, digital filters, color modulator, and timing generator, In order to support mul- tistandard video signals, a programmable systolic architecture is adopted in designing various digital filters. Interpolation digital filters are also used to enhance SNR 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.
