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

A self-adaptive switching method and system for multi-encoding format program streams. The method comprises: grouping, according to a bandwidth and an encoding format, program streams, providing two decoders while creating dual threads, switching according to an adaptive bandwidth determined by a network velocity, when the program streams of different encoding formats are required to be switched, switching and playing a group of the program streams that are not played, wherein a group of the program streams which is in use is not required to be reset, thus realizing the self-adaptive seamless switching, thereby avoiding the occurrence of phenomena such as discontinuity in playing, frame skip or pausing of a video picture, greatly guaranteeing the switching of high-definition program streams, bringing about great convenience to the watching of a user, and improving the user experience. Meanwhile, a TS stream in a group with the large bandwidth is downloaded in a segmentation manner, thereby further avoiding the jamming and pausing problem, further bringing about convenience to the watching of the user, and better improving the user experience.

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 implemented 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...
