Problems solved by technology

[0013] But, in the structure of prior art as mentioned above, when the loss of the packet in network reaches more than a certain degree, above-mentioned video on demand server 100 will disconnect network dialogue (session), or reduce bit rate, if Reducing the above bit rate will inevitably reduce the data allocated for each frame, which will greatly reduce the image quality

Embodiment Construction

[0025] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Fig. 4 is a schematic diagram of correspondingly adjusting the frame rate according to the packet loss rate according to the method provided by the present invention.

[0027] As shown in Figure 4, according to the real-time transmission control protocol, the error situation on the network can be fed back on the packet loss rate. Using the above packet loss rate information, when the video stream is generated in the decoder, the frame rate is adjusted according to the above packet loss rate. Adaptive adjustment.

[0028] The graph in Fig. 4 shows the adjustment of the frame rate according to the obtained packet loss rate in the experiment.

[0029] As shown in the figure, when the packet loss rate is high, the frame rate is reduced, and when the packet loss rate is low, the frame rate is increased. The principle is as follows.

[0030] The high...

Abstract

This invention relates to data package lose frame speed adjusting method, which comprises the following steps: through decoder generated visual flow and referring data package information, realizing above visual frequency speed for adaptive adjusting; the data package information refers to error information according to real time transmission agreement RTCP to feedback error information on above decoder.

Description

technical field [0001] The invention relates to a method for adjusting the frame rate according to the packet loss rate, in particular to a method for adjusting the frame rate according to the packet loss rate when using a wireless network to provide video-on-demand services. Background technique [0002] FIG. 1 is a schematic diagram of the structure of a video-on-demand service system using a wireless network to provide video-on-demand services in the prior art. FIG. 2 is a schematic diagram of a video-on-demand protocol for implementing a video-on-demand service. [0003] The above VOD video on demand service is an acronym for video on demand, that is, a new type of video service that provides video services such as movies or news to users through telephone lines or cables according to user requirements. The above-mentioned video-on-demand service is a service in which the video programs are digitally compressed and stored in the video server, and then the programs that ...
