Embodiment Construction

[0022] The invention provides a method and system for processing audio and video data uplink and downlink in a TD-SCDMA system. The system includes a network side device and a mobile terminal; it is characterized in that the mobile terminal includes a main processor (Spreadtrum SC8800d chip), a coprocessor (MV8602), a MIC or a headset, a RECEIVER or a headset, an LCD and a CAMERE (OV8650). in:

[0023] The main processor is used to receive the audio and video data from the network side in the downlink and decompose them into audio data and video data according to the H.324 protocol, and then transmit the audio and video data to the coprocessor and RECEIVER or headset respectively; It is also used to send mixed encoding of the audio data and video data to the network side after receiving the video data from the coprocessor and the audio data collected by the MIC or headset in the uplink;

[0024] The coprocessor is used to decode the code stream and send it to the LCD display ...

Abstract

The invention relates to a method and system for the uplink and downlink processing audio and video data in a TD-SCDMA system. The downlink processing method includes the steps that when the main processor of a mobile terminal receives audio and video data sent by a network side, the audio and video data is separated into audio data and video data according to the H.324 protocol; on the one hand, the main processor transmits the audio data to an RECEIVER or headsets to be played; on the other hand, the main processor sends the video data to a co-processor of the mobile terminal and after receiving a video code stream from the main processor, the co-processor decodes the code stream and sends the code stream to an LCD to be displayed. The uplink processing method is the inverse process of the downlink processing method. Moreover, the system of the invention comprises equipment of the network side and the mobile terminal and is characterized in that the mobile terminal comprises the main processor, the co-processor, an MIC or headsets, the RECEIVER or headsets, the LCD and video capture equipment. The method and system of the invention ensure that the video phone service can be realized on the mobile terminal of the TD-SCDMA in the TD network.

Description

technical field [0001] The invention relates to a processing method of audio and video data in a mobile communication system, in particular to a method and system for processing audio and video data uplink and downlink in a TD-SCDMA system. Background technique [0002] With the development of personal mobile communication technology, 2.5G / 2.75G mobile terminals are becoming more and more popular, but 2.5G / 2.75G mobile communication networks can only provide voice services and data services, and cannot meet users' needs for video communication. [0003] After years of development, the domestic TD-SCDMA network has become more and more mature, and will soon enter the commercial stage. The development and successful commercial use of TD-SCDMA technology enables ordinary 3G terminal users to enjoy video call services conveniently and quickly. [0004] TD-SCDMA mobile terminals can provide a clearer video call function, because in a video call, it is necessary to process the rec...
