| Abstract: | This paper presents an adaptive BTC algorithm for digital transmission of broadcasting TV signal.It reduces bit rate by adaptive transmission a difference of means in a subblock and nonlinear quantizing the difference,It shows by computer simulating and hardware experiment that the algorithm is simple and easy to implement with real-time hardware,has powerful capacity to resist error code.A better result is obtained by coding monochrome and color TV signal with the adaptive BTC algorithm. |
