Video and audio control response, bandwidth adapting method, and server

Abstract

The invention relates to a video and audio control response and bandwidth adapting method, a server and a storage medium applied to network streaming. A server transmits a received control command to a streaming controller, and simultaneously, a player clears outdated streaming data in a buffer area. The streaming controller controls the source of a video / audio capturing device, and estimates the streaming data quantity in the buffer area, and the estimated streaming data quantity in the buffer area and bandwidth variation information are transmitted to a streaming converter. If the streaming data quantity in the buffer area is smaller than a critical value, a streaming time stamp and a parameter multiplying power are adjusted according to the estimated streaming data quantity in the buffer area and the bandwidth variation information to adjust the depletion rate of the streaming data of the buffer area, so as to accumulate data of the buffer area over again.

Description

technical field [0001] The present invention relates to an audio-visual control method, and in particular to an audio-visual control response and bandwidth adjustment method applied to network streaming, a server and a storage medium using the method. Background technique [0002] Generally, when watching audio and video streams through the network, due to the huge amount of transmitted data, in order to cope with the change of bandwidth, the player must accumulate a certain length of data buffer to adjust to the change of bandwidth, so as to avoid interruption or frustration during playback. status. However, for applications that transmit audio and video streams over the network, an excessively long buffer will cause delays in the response of audio and video interactive control, causing inconvenience to users. For example, for an application that requires frequent channel selection while watching TV, the user may feel that the reaction time for displaying the next program ...

AI Technical Summary

Problems solved by technology

Such an approach will cause obvious unsmooth playback, and there is a lot of room for improvement in using buffers for bandwidth adjustment
