Problems solved by technology

[0003] In the current system, in the multiple screens seen by the terminal, each screen does not display the terminal name. The current feasible solution is to add the subtitle function of the sending direction terminal in the sending direction of all terminals, and use this function to display the terminal name, that is Patent 99111318, the cost of this solution is high, and each terminal needs to be added with a direction subtitle device. The maintainability is poor, and the direction subtitles of each terminal need to be maintained. If the terminal does not support the function of sending direction subtitles, the digital multi-screen return Screen terminal name cannot be displayed

Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing:

[0022] Taking the H.320 protocol system and the H.323 protocol system as examples, the processing method described in the present invention is specifically described as follows. See Figure 1:

[0023] Step 1: The interface module gets the terminal data from the terminal;

[0024] Second step: the core module decodes video image data from the video data in the data obtained in the first step;

[0025] The third step: the core module synthesizes the multi-channel data obtained in the second step, that is, the multi-channel decoded video image data, into a digital multi-screen;

[0026] With reference to Figure 1, the specific implementation is as follows:

[0027] Process multiple screens in a loop, process the first screen first,

[0028] The obtained image data buffer of the current picture compresses the size of the image by neutralizing several pixels into one pixel a...

Abstract

The displaying method of the technological scheme includes the following steps: for the interface module to take data from the terminal; to take data the terminal sends from the interface module; to decode the data to obtain video image data; to synthesize digital multiple picture with several channels of decoded video image data; to add the terminal name caption to corresponding position of the digital multiple picture; to encode the digital multiple picture data with caption and feed it to the interface board; to send the data with the interface board to the terminal to complete the multiple picture feedback with displayed terminal name. The present invention makes it possible to realize the terminal name display in digital multiple picture feedback in high efficiency and low cost.

Description

technical field [0001] The invention relates to a digital multi-picture return transmission in a video conference system, and more specifically relates to a method for displaying terminal names of each picture in a digital multi-picture transmission. Background technique [0002] In video conferencing systems, digital multi-screen backhaul technology (that is, multiple terminal images form multi-screen and send back to each terminal) has long been widely used in the industry. In the multimedia video conferencing system, it is mainly based on the H.320 protocol or the H.323 protocol. [0003] In the current system, in the multiple screens seen by the terminal, each screen does not display the terminal name. The current feasible solution is to add the terminal subtitle function in the transmission direction of all terminals, and use this function to display the terminal name, that is Patent 99111318, the cost of this solution is high, and each ...
