Embodiment Construction

[0059] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0060] The embodiment of the present application provides a code rate switching method, which can be implemented by a computer device. Wherein, the computer device may be a mobile terminal such as a mobile phone, a tablet computer, and a notebook, or may be a fixed terminal such as a desktop computer.

[0061] The method provided in the embodiment of the present application may be applied on a terminal. Multiple video packages with different bit rates can be stored in the server. When a terminal user watches a video program, the terminal can determine the target bit rate used at the target time based on the load information of the processor, and then request the server for the video package at the target bit rate. video packages...

Abstract

The application discloses a code rate switching method and device, which belong to the technical field of communication. The method includes: based on the detected load information of the processor at at least one historical moment, predicting the load information of the processor at the target moment; respectively determining the maximum code rate corresponding to each load information, wherein each load information includes at least one historical moment load information and predicted load information; based on the determined maximum code rates, determine the overflow probability corresponding to each preset code rate to be selected, wherein the overflow probability is that the code rate to be selected at the target moment is greater than the predicted The probability of the maximum code rate corresponding to the load information; based on the overflow probability corresponding to each code rate to be selected, among the code rates to be selected, select the target code rate used at the target time. This application can effectively solve the technical problems in the related art that the user cannot obtain a good viewing experience and the operation is troublesome for the user.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for switching code rates. Background technique [0002] Now, people can conveniently watch various live programs (such as sports events) on their mobile phones or computers to achieve the purpose of daily entertainment. However, sometimes the released live programs may have too high requirements on the decoding performance of the terminal, or the decoding capability of the terminal may change greatly due to the different status of the terminal, resulting in stuttering or clearness when people watch the live program. The phenomenon of low intensity makes the user's viewing experience extremely poor. [0003] The solution adopted in the related art is to encode multiple live programs with different bit rates and release multiple live links (such as standard definition, high definition, etc.), and the user selects an appropriate link to play...
