Problems solved by technology

[0005] The solutions in related technologies require the user to have sufficient professional knowledge. When the user selects the wrong link, the user cannot obtain a good viewing experience. At the same time, the user is also required to manually select and confirm, which is troublesome for the user to operate.

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 invention discloses a code rate switching method and device, and belongs to the technical field of communication. The method comprises the steps of predicting load information of a processor at atarget moment based on detected load information of the processor at at least one historical moment; separately determining the maximum code rate corresponding to each piece of load information, eachpiece of load information comprising the load information of at least one historical moment and the predicted load information; determining an overflow probability corresponding to each preset to-be-selected code rate based on each determined maximum code rate, the overflow probability being a probability that the to-be-selected code rate is greater than the predicted maximum code rate corresponding to the load information at the target moment; and based on the overflow probability corresponding to each to-be-selected code rate, selecting a target code rate used at a target moment from the to-be-selected code rates. By the adoption of the method and device, the technical problems that in the prior art, a user cannot obtain good watching experience, and user operation is troublesome can beeffectively solved.

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...
