Description
technical field [0001] The invention belongs to the technical field of network and audio and video data processing, in particular to a digital home set-top box with a wireless gateway function. Background technique [0002] A set-top box is a conversion device that converts digital television signals into analog signals. It decodes and restores digitally compressed image and sound signals, outputs analog video and sound signals, and provides high-quality TV programs to viewers through TV monitors and audio equipment. The set-top box is also a multimedia terminal. It has a hardware architecture similar to that of a home computer and a dedicated real-time operating system and application software. It not only has the function of decoding digital signals, but also can analyze and decrypt user authorization information. [0003] The current situation is that the penetration rate of cable TV is the highest, and digital TV needs a set-top box to connect to the cable TV network. I...
