Embodiment Construction
[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0026] figure 1 A flowchart illustrating a computer-implemented method for switching bit rates of audio and video information played online in one aspect of the present invention. The method according to the invention comprises step S1, step S2, step S3 and step S4. Wherein, the method according to the present invention can be realized by a code rate switching device in the user equipment, for example, by devices such as an application module, an operating system, and a processing controller in the user equipment. Among them, the user equipment is a modern intelligent electronic equipment that can automatically and quickly perform a large number of numerical calculations and various information processing according to a pre-stored program. Its hardware includes but is not limited to microprocessors, FPGAs, DSPs, embedded equipment, etc. Wherein, the user e...

The invention provides a method, a device and equipment for switching code rate of audio and video information played on line through a computer. The technical scheme includes that method include steps of acquiring cached residual play duration supported by to-be-played data information; judging whether the residual play duration is within a preset play duration range or not; determining new code rate required to be switched to according to the preset play duration range if the residual play duration is within the preset play duration range; and acquiring to-be-cached data information corresponding to the new code rate from the audio and video information and then playing the data information. By the method, the device and the equipment, balance between internet speed and play smoothness can be achieved, manual regulation is omitted for users, play interruption or reload of audio and video and the like during code rate switching can be avoided, frequency of the code rate switching is controlled, and watching experiences of users are improved.
Description
technical field [0001] The present invention relates to the field of computer technology, in particular to a computer-implemented method, device and device for switching the code rate of audio and video information played online. Background technique [0002] Due to the large difference in network speed between different users, many audio and video providing websites often provide users with audio and video with the same content but different bit rates to meet the needs of different users. However, in the prior art, it is usually necessary for the user to manually select the code rate of the audio and video when playing the audio and video, and the code rate cannot be automatically switched according to the actual environment during the user's playback, causing inconvenience to the user. Contents of the invention [0003] The object of the present invention is to provide a computer-implemented method, device and equipment for switching the code rate of audio and video info...
