Method and system for playing multi-track content in network audio-visual

Abstract

The invention relates to a method and a system of multi-audio-track content play in network seeing and hearing. The method of the multi-audio-track content play in the network seeing and hearing comprises downloading an audio / video file which is provided with multiple audio track content inside in an enclosed mode through a network; decoding the audio / video file, obtaining track label information of the multiple audio track content, and showing the track label information to a user; and selecting a corresponding audio track to play the audio / video file according to preset rules when the user does not set preference selection to the track label information. Due to the fact that a plurality of coded audio tracks are enclosed in a network coding program, in download and play, when the user sets the preference selection, the audio / video file is played according to the audio track selected by the user, when the user does not set the preference selection, the corresponding audio track is selected to play the audio / video file according to the preset play rules of a decoder. Therefore, the method and the system of the multi-audio-track content play in the network seeing and hearing have the advantages of not only saving storage space and bandwidth, but also being capable of achieving real time seamless switching of audio tracks in network audio / video play, enabling the user to be capable of defining personal preference audio tracks in a user-defined mode, and greatly improving user experience.

Description

technical field [0001] The invention relates to the field of network audio-visual technology, in particular to a method and system for playing multi-track content in network audio-visual. Background technique [0002] With the development of video technology, compared with local video such as DVD and TV, online video has gradually become a development trend. Since online videos do not have to wait for long advertisements, viewers can freely search for their favorite programs, and have good interaction and interactive sharing features, which bring a brand-new playback experience to viewers and are becoming more and more popular among viewers. [0003] However, in the current online video services on the Internet, usually only one audio track (language) experience can be provided for a program, making it impossible to seamlessly switch between multiple audio tracks (languages) in online video on demand and live broadcast. In addition, in the existing network audio service, us...

Problems solved by technology

[0003] However, in the current online video services on the Internet, usually only one audio track (language) experience can be provided for a program, making it impossible to seamlessly switch between multiple audio tracks (languages) in online video on demand and live broadcast.

In addition, in the existing network audio service, usually only one sound (such as the original sound) experience can be provided for a song. One sound to achieve, but the sound quality and sound effect of the monophonic sound is poor

[0004] In addition, although the storage of some existing DVDs and Blu-rays adopts multi-track packaging technology, which can realize local playback of multi-track content, however, in this way of local playback of multi-track content, the file is large and the bit rate is high, usually A program is a CD, which cannot provide adaptive selection in the network, cannot support multi-track switching of content segmentation (fragmentation), and can only play and switch audio track content in the order of audio track packaging

[0005] In addition, some network video manufacturers provide encoding of two programs (same video, different audio) and cooperate with server interactive switching to achieve an experience similar to multi-track switching, but such a solution will double the video storage and distribution on the one hand. Deployment; on the other hand, switching from one program to another requires downloading, SEEK dragging, and only key frames can be switched when switching, which is difficult to implement and maintain, and cannot achieve real-time seamless experience, nor can it realize user Smart Choices for Preferences
