A real-time video signal processing chip
A real-time video signal processing chip for video data compression which combines block truncation coding (BTC) and a conventional motion compensation (MC) algorithm is presented. The regularity and simplicity of the BTC algorithm strongly suggest that it is quite suitable for an efficient VLSI implementation. It is shown that the proposed BTC-based system is much better than the conventional system in terms of implementation, complexity, and accuracy. Two benchmark sequences are used as test examples. The clock rate of the designed chip is about 47 MHz, which is suitable for most video applications. >
