Problems solved by technology
[0002] Existing digital TV has been more and more widely used due to its clear image quality and networked methods. However, when digital audio and video streams are transmitted on demand, the data packets of audio and video are too large, even if they are transmitted before transmission. In addition to compression, the amount of data packets is still high. In addition, after receiving digital TV, it also needs to be decompressed and processed, and then analyzed. In this way, it is often impossible to achieve orderly on-demand display, resulting in garbled characters on the screen, and the picture will be unclear. , this complex method and structure does bring inconvenience to playback
