Problems solved by technology

The method for determining the code rate for the first access has the following defects: the user cannot accurately select the appropriate code rate for the first access because the user cannot know the quality of the mobile communication network when playing the video and the detailed configuration of the terminal itself. If the first access code rate is inappropriate, the quality of video playback will be reduced; moreover, since the first broadcast bit rate is selected by the user, it cannot be changed during playback. If the quality of the mobile communication network accessed by the user changes, then The bit rate cannot be switched for the first access, so the video playback quality cannot be guaranteed
If you play a video with a certain bit rate first, and then slowly increase or decrease the bit rate, it will inevitably lead to unnecessary video bit rate switching. Video bit rate switching not only needs to occupy server resources on the network side, but also affects user video. Playback quality makes bit rate switching costly

Embodiment Construction

[0022] There may be many types of networks supported by the terminal at present, and the hardware configuration of the terminal itself is different, such as the terminal's central processing unit (CPU, CentralProcessUnit), memory, display screen, supported resolution, and video codec type supported by the terminal 1. Network types and performance indicators vary widely, so that different terminals have different playback capabilities. In order to adapt to various terminals as much as possible, the network side needs to be able to provide more different encoding formats and different bit rate parameters.

[0023] Based on this, the embodiment of the present invention provides a method and device for determining the first access code rate of video playback, which is used for determining the first access bit rate of video playback by the network side according to the type of network currently accessed by the terminal and the hardware configuration of the terminal when using the ter...

Abstract

The utility model discloses a method and a device for determining of a video playing first access code rate. The video playing first access code rate is selected accurately, the code rate switching frequency is reduced and the video playing quality is guaranteed. The method comprises steps of receiving a video playing request which is sent by a terminal, wherein the video playing request carries media format information supported by the terminal; acquiring the network type information of a terminal access network and the terminal capacity value of the terminal; acquiring a data list which is matched with the network type information and the media format information from a code rate fitting bank which is stored in advance, and selecting the code rate value corresponding to the terminal capability value as a first access code rate from the acquired data list.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and a device for determining the first access code rate of video playback. Background technique [0002] With the development of mobile Internet technology and terminal technology, mobile communication networks can provide users with more and more services. For example, through mobile communication network streaming media and file downloading, it provides users with terminal video services mainly in the form of audio and video. Users can watch live video, perform video on demand and video download through mobile terminals. There are two viewing methods: downloading and instant receiving. Downloading and watching requires users to download the video files to the terminal and then play and watch them. Instant receiving and watching adopts the method of downloading and watching, watching on-demand, live broadcast or scrolling. broadcasting and other ty...
