Problems solved by technology

The existing video sharing technology has the following defects: First, it is impossible to adaptively select the appropriate bit rate and encoding format, resulting in unreasonable use of network bandwidth and affecting user experience
However, the existing video sharing websites ignore these rules, and provide video media data to users regardless of any content of video or any needs of users, thus unnecessary wasting the user's bandwidth, especially the bandwidth of mobile terminal users.

Embodiment Construction

[0039] 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 through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] figure 1 Shows a block diagram of a media playback system according to an embodiment of the present invention, according to the following figure 1 The media playing system of the present invention is described in detail. The system mainly includes a control module, a transcoding module and a release module. The control module is used to process user requests and set transcoding parameters. The transcoding module converts the program accessed by the user from the original format to a format suitable for the user based on the transcoding parameters. The publishing module is used...

Abstract

The invention provides a media playing system. By the system, a user is allowed to switch between a pure audio playing mode and a mixed video playing mode, a transcoding parameter can be flexibly set according to an on demand request of the user, and a program requested by the user can be transcoded from an original format into a format required by the user on the basis of the obtained transcoding parameter, so that the user can selectively appreciate audio contents extracted from an original program to save network traffic and bandwidths, and the contents of a specific code rate can be selected without the limitation of specifications provided by a media server. Moreover, a video media provision website is not required to store and provide contents in different formats for users of different terminals, so that a storage space is saved.

Description

technical field [0001] The invention relates to the field of digital media, in particular to audio and video digital information processing. Background technique [0002] Internet-based video sharing has been popularized on a large scale. On the Internet, users can easily obtain media programs such as news videos, user-uploaded videos, and film and television works through video-sharing websites. The usual processing flow of the current media playing system is: making a video media program with a specific encoding specification and storing it on a file server, and providing the video media data to the user in response to receiving a user request. [0003] The current video sharing technology needs to be transcoded in advance, and the media file in the format required by the user is generated before the user enjoys it. The user can only passively select the format provided by the server, and can only use a specific terminal such as a computer that can read data in this format...
