The article focuses on the features of the video compression encoders with digital signal processors (DSP). According to the author, video encoding and decoding (codec) involves sacrificing some degree of picture quality for a lower bit rate that facilitates transmission and storage. In connection, an advanced video codec can achieve compression ratios of between 60:1 and 100:1 with sustained throughput that makes it possible to squeeze video with a high data rate. Meanwhile, the digital video recorders (DVR) are also mentioned in the article in which these equipment are the most widely used application for real-time video encoders.
