Problems solved by technology

When the terminal is gradually trying higher bit rate content within the available bandwidth, the bit rate of the content requested to play may exceed the maximum supported bit rate of the terminal, resulting in a freeze, black screen or blurred screen for a period of time, and then automatically reduces The code rate requests fragments with a l

Embodiment Construction

[0073] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0074] An embodiment of the present invention provides a method for selecting playable code rate content, which is suitable for terminals. The terminal sends the terminal code rate capability indication to the server, and the server obtains the maximum supported code rate of the current terminal according to the terminal code rate capability indication. After filtering the information of the playlist in the index file, please refer to figure 1 , the method includes...

Abstract

The embodiment of the invention provides a method and a device for selectively playing the code rate content. The method comprises the following steps that a content playing instruction of a user is received, and the content playing instruction contains a uniform resource locator (URL) of an index file; a content playing request is sent to a server, and the content playing request contains the URL of the index file and a terminal code rate capacity indicator; the index file which is returned after being filtered in accordance with the current largest terminal support code rate obtained by the server in accordance with the terminal code rate capacity indicator is received; and a play list is selected from the index file returned after being filtered. By using the method and the device, playing abnormity caused by the fact that the request is beyond the content of the largest terminal support code rate when the content is played by the terminal can be avoided, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to a method and device for selecting content with a playable code rate. Background technique [0002] Hypertext Transfer Protocol (HTTP) Adaptive Streaming (HAS) technology based on Hypertext Transfer Protocol (HTTP) Adaptive Streaming (HAS) technology uses HTTP to transmit media content to users. This technology can reduce the technical complexity of the head-end server and improve the media content The penetration capability of content in network devices has become a development trend of the streaming video industry. [0003] A key of the HAS technology is to sequentially cut the content (that is, the same channel or movie) into slices, each slice has the same bit rate, resolution, and encoding, and the time length of each slice is the same, generally 2 to 10 Seconds or so, such a set of description information and access links of slices constitute a playlist. The...
