Embodiment Construction

[0038] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039] In the present invention, when performing IMS system video playback, the current frame image data of the video image is received, and the gray value of each pixel on the display screen is determined according to the received current frame image data and the resolution of the display screen, and the The grayscale value of each pixel point is sent to the display screen for display and playback. Through the above processing, the home gateway device does not directly push the image data to the TV terminal after receiving the image data, but calculates the gray value of each pixel on the display screen according to the received data and the resolution of the TV terminal display screen, so as to display Each pixel on the screen displays the corresponding gray value...

Abstract

The invention provides a video playing method in an IP multimedia subsystem (IMS) system. The video playing method comprises the steps of receiving current frame image data of a video image, determining grey levels of pixel points on a display screen according to the received current frame image data and resolution of the display screen, and sending the determined grey levels of the pixel points to the display screen to display and play the grey levels. The invention further provides a home gateway device and a video playing system. By applying the video playing method, the home gateway device and the video playing system, image display definition can be improved.

Description

technical field [0001] The invention relates to image communication technology, in particular to a video playing method in an IMS system, a home gateway device and a system. Background technique [0002] The structure of the video service system based on IMS network is as follows: figure 1 As shown, the system includes three key network element units: video service main control server, home gateway, and TV terminal. Among them, the multimedia IVR platform, that is, the video service main control server, is responsible for receiving the user's 2G call request and pushing the video content to the home gateway; the home gateway is responsible for receiving the video content transmitted by the video service main control server, connecting with the TV terminal, and transcoding The video content is transmitted to the TV terminal; the TV terminal is used to display the video content. [0003] exist figure 1 In the system structure shown, the video content pushed to the user term...
