Problems solved by technology

[0017] And, as explained above, the shortcoming of existing technology VOD service is: have nothing to do with the error situation of transmission network, if once decide above-mentioned MPEG-4 encoding mode, all applicable according to this mode, because do not consider the error situation of network at all, It has a problem that is inconvenient to correct

Embodiment Construction

[0047] An embodiment of the method for selecting an MPEG-4 encoding mode in the real-time streaming service of the present invention will be described in detail below with reference to the accompanying drawings.

[0048] Fig. 3 is a schematic diagram showing the configuration of a VOD service system using the wireless network of the present invention. FIG. 4 is a schematic diagram of each mode of an MPEG-4 encoder included in the VOD server of FIG. 3 .

[0049] In the VOD service using packet networks such as wireless networks, in order to correspond to network error conditions, the present invention considers the characteristics and complexity of the G-4 coding mode when using wireless networks for streaming transmission, in order to ensure that the receiving terminal can grasp The PLR ​​() information of the error status selects the above-mentioned several MPEG-4 encoding modes, and the above-mentioned MPEG-4 encoder has multiple modes.

[0050] As shown in FIG. 3 , the VOD...

Abstract

This invention relates to one MPEG-4 code mode selection method in real time flow transmission, which comprises the following steps: receive terminal receives information form above receive terminal; selecting coder mode according to above information lost information. This invention advantages lie in the following: considering wireless network for sending and MPEG-4 code mode and complexity through PLR information according to terminal to select above several kinds of code modes.

Description

technical field [0001] The present invention relates to the invention of the MPEG-4 encoding mode selection method during real-time streaming service, and more specifically, relates to the MPEG method for improving the image quality of the VOD (Video On Demand) streaming server side when using the real-time streaming service of the wireless network. -4 encoding mode selection method. Background technique [0002] FIG. 1 is a schematic configuration diagram of a VOD service system using an existing wireless network. [0003] First of all, the above-mentioned so-called VOD service refers to a new-concept video service business that provides basic video services such as movies or news through telephone lines or cables according to the requirements of service users. The above-mentioned VOD service compresses video programs into numbers and stores them in a video server, and uses a high-speed communication network to provide users with preferred program services. Users can selec...
