Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The method for controlling the data code rate in the wireless conference television system of the present invention, such as figure 1 shown, including the following steps:

[0034] Step 101: When the data code rate needs to be adjusted, the mobile terminal sends request information for adjusting the data code rate to the conference control system;

[0035] Here, the timing when the data code rate needs to be adjusted is: other terminals connected to the conference control system need to see important information such as text, views or images; other terminals will notify the mobile terminal of the required data code rate, so After receiving the notification, the above-mentioned mobile terminal sends request information for adjusting the data code rate to the conference control system; or,

[0036] The user of the mobile termin...

Abstract

The invention discloses a method for controlling data code rate in a wireless video conferencing system, which comprises the following steps: when data code rate is required to be adjusted, transmitting a request message for adjusting the data code rate to a conference control system by a mobile terminal; after the conference control system receives the request message, determining the mobile terminal to support the data code rate requested in the request message and transmitting a signalling for altering the data code rate to the mobile terminal; and after receiving the signalling, adjusting own unloading data code rate by the mobile terminal according to the target data code rate in the signalling. The invention also discloses a system for controlling the data code rate in the wireless video conferencing system. By adopting the method and the system in the invention, data code rate control can be realized in the wireless video conferencing system.

Description

technical field [0001] The invention relates to a wireless conference TV system technology, in particular to a method and system for controlling data code rate in a wireless conference TV system. Background technique [0002] The wireless conference TV system is a brand-new video conference method based on the wireless communication network and the fixed video conference system. Specifically, the mobile terminal is connected to the conference control system of the fixed video conference system through the wireless communication network, and performs video conference connection and data exchange with other wireless or wired terminals through the conference control system. [0003] The current wireless communication network is mainly the third-generation mobile communication technology (3G) network, and in the 3G network, all users share a limited bandwidth, and the bandwidth is less than half of the bandwidth of the fixed network. In the system, video data is generally sent ...
