数字电视信号直接进行切换的算法研究

Algorithm Research on Switching Digital TV Signal Directly

提出一种可以对数字电视信号在不转换成模拟信号的前提下直接进行切换的算法,主要是找到合适的切入点,并且在切入过程中作了恰当地处理,以保证画面的平滑过渡,最后给出了实验结果。

An algorithm is proposed in this paper. Through this algorithm, digital signals which are not converted into analogy signals can be switched directly. The key is to search a switching point in the transport stream and to make sure the switching process. The experiment result is also provides.
