Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] figure 1 It is a flowchart of an adaptive switching method for multi-coding format program streams in an embodiment, such as figure 1 As shown, the method includes the following steps:

[0027] S10: Divide the program stream into multiple groups according to the size of the bandwidth, and the audio and video encoding formats of each group are different.

[0028] Since the same program currently has program streams of multiple audio and video encoding formats, and the bandwidths of program streams of different audio and video encoding formats are different, program streams of various encodi...

Abstract

The invention relates to a self-adaption switching method and system for multi-coding form program streams. The self-adaption switching method for the multi-coding form program streams comprises the steps that the program streams is grouped according to band width and a coding form, two decoders are provided, a double thread is established simultaneously, the matched band width is determined to perform switch according to network speed, when the coding form is different and needs to be switched, the switch playing is performed by an un-played group, the used group does not need to be reset, so that self-adaption seamless switching is achieved, therefore, the phenomena that the playing is incoherent, or frame skip occurs, or the video picture pauses are avoided, the switching of high definition program streams is greatly guaranteed, great convenience is brought to a user for watching, and the experience of the user is improved. Meanwhile, segmentation downloading is performed on TS streams in groups with a large band width, the problem of pausing is further avoided, further convenience is brought to the user for watching, and the experience of the user is further improved.

Description

technical field [0001] The invention relates to the communication field, in particular to an adaptive switching method and system for multi-coding format program streams. Background technique [0002] With the continuous development of TV broadcasting services and the continuous improvement of network bandwidth, adaptive viewing of high-definition and standard-definition programs has been realized. The current solutions for adaptively switching high-definition and standard-definition program streams are all realized on the basis of consistent audio and video encoding formats. For the adaptive switching of program streams in different audio and video encoding formats, it involves the switching of decoders, which will cause the decoder to be reset and interrupt audio and video decoding, so when adaptively switching program streams in different audio and video encoding formats, it will This results in incoherent playback, frame skipping, or pauses in the video screen, which gr...
