Abstract

The invention relates to an intelligent terminal, in particular to a digital home intelligent terminal for realizing integration of a telephone network, a wide-band network and a broadcast television network based on various audio video standards. The design of taking an EoC (Ethernet over coax) user side processor as a center is utilized, and the EoC user side processor receives wide band network data of central office equipment, comprising Vedio-On-Demand signaling, wide band tri-network data, internet television signals and the like. Vedio-On-Demand digital signals of digital television can be transmitted from a coaxial cable through modulating, and the wide band data signals can be transmitted to a wireless local area network card needed by homes through wireless network.

Description

1. Technical Field [0001] The invention relates to an intelligent terminal, in particular to a digital home intelligent terminal that realizes the integration of telephone network, broadband network, and broadcast television network with multiple audio and video standards. 2. Background technology [0002] Existing audio and video standards usually use MPEG-1, MPEG-2, MPEG-4, H264 and other standards, but these standards have long been blocked by foreign manufacturers through patents. If these standards are used, foreign manufacturers will be paid a large amount every year. Patent royalties. [0003] AVS (Audio Video coding Standard) is a second-generation source coding standard with independent intellectual property rights in China. The key problem it solves is the coding and compression of massive digital audio and video data, also known as digital audio and video coding and decoding standard technology. It is the links of digital information transmission, storage, and playback....
