Time division-synchronous code division multiple access (TD-SCDMA)/ IP double network cooperation multimedia telephone, system and communication method thereof

Abstract

The invention relates to a Time division-synchronous code division multiple access (TD-SCDMA) / IP double network cooperation multimedia telephone, a system and a communication method thereof. A TD-SCDMA chipset module is used to perform channel access on a multimedia telephone terminal so that voice accesses to a TD-SCDMA network through a circuit domain channel of the TD-SCDMA chipset module and video or multimedia digit information accesses to an IP network through a packet domain channel of the TD-SCDMA chipset module. A terminal telephone number is taken as positioning identification. Network addressing and exchange of the terminal can be realized through the cooperation of an IP Internet server system so that non audio frequency communication between the terminals based on the IP network can be realized. The voice and the video are synchronously restored after reaching the opposite terminal. In the invention, fusion of the double network communication can be realized. Low latency and high quality of the voice communication can be guaranteed and a large information amount video communication requirement of a high-definition large display screen can be satisfied. And on-demand flexible expansion of the service can be effectively realized.

Description

technical field [0001] The present invention relates to a terminal technology for realizing wireless visual communication and multimedia advertisement precise push broadcast on a multimedia phone, in particular to a terminal technology for realizing voice through TD-SCDMA network and non-voice data and video signals through IP on a traditional multimedia phone The TD-SCDMA / IP dual-network cooperative wireless visual multimedia communication terminal, multimedia communication system and communication method based on the system can realize logical exchange, addressing and positioning, operation management, service billing and Value-added services such as advertising push. Background technique [0002] Using the existing visual communication technology in which audio and video are transmitted on the same channel, due to the large amount of information in the video signal, the transmission rate and quality of the audio signal will be greatly reduced, resulting in high delay of t...

AI Technical Summary

Problems solved by technology

In the RDI / UDI mode of the circuit domain videophone, the transmission rate is 56kbps / 64kbps, and the video and audio codec processing is carried out in the TD-SCDMA chip module. The audio / video codec rate and transmission rate are relatively low, so it cannot Adapt to the real-time video requirements of larger screens, and the intercommunication technology of visual communication and multimedia applications between networks of different 3G standards is also relatively complicated and costly

[0004] The use of fixed multimedia phones for households is generally designed to be suitable for multi-service purposes, and a large display screen with higher resolution (such as a 7-inch screen) is required. Therefore, the requirements for video compression and transmission are higher. Commonly used video compression and transmission Technology is difficult to meet its requirements, prone to video delays
