Self-adaptive cache adjustment control method and device and self-adaptive player

Abstract

The invention provides a self-adaptive cache adjustment control method and device and a self-adaptive player. The method comprises the following steps: continually computing a receiving occupying rate of a receiving buffering region, a playing occupying rate of a playing buffering region and a current network health index in a process of playing a streaming media file by the player; and dynamically adjusting the size of the current receiving buffering region and the current playing buffering region according to the current network health index, the receiving occupying rate and the playing occupying rate. A general buffering region is composed of the current playing buffering region and the current receiving buffering region; the current playing buffering region and the current receiving buffering region are dynamically changed along with the current network health index and the current network health index can reflect the speed of a current network, so that the general buffering region can be dynamically changed along with the current network health index; therefore, the method provided by the invention can dynamically adjust the size of the general buffering region according to the network speed and the aims of not discarding data packets and also guaranteeing the sufficient utilization of resources can be realized.

Description

technical field [0001] The invention relates to the field of streaming media playback, in particular to a control method and device for adaptively adjusting buffers and an adaptive player. Background technique [0002] With the progress of the times, it has become a habit for humans to use electronic devices to watch streaming media. The process of streaming media playback is that the server encapsulates the encoded streaming media data into data packets that conform to the RTP protocol for real-time streaming media transmission and sends them to the streaming media through the network. Media player, streaming media player receives data packets at a certain speed, and plays the data packets at a certain speed, thereby playing streaming media files. [0003] However, in real life, due to unstable network conditions, there will be delays and jitters in the data packets sent by the server to the streaming media player, which will cause the data of the streaming media player to ...

AI Technical Summary

Problems solved by technology

[0003] However, in real life, due to unstable network conditions, there will be delays and jitters in the data packets sent by the server to the streaming media player, which will cause the data of the streaming media player to be out of sync. Therefore, in order to achieve synchronous and continuous streaming media playback, currently The caching technology is used to increase the buffer in the streaming media player to store the data packets sent by the server

[0004] However, the size of the buffer in the existing streaming media player is a fixed value. Since the playback of streaming media depends on the network, the playback data packet of the streaming media player is at a certain speed. When the network speed is fast, the server sends The data packets will exceed the capacity of the playback buffer, and the player will adopt a packet loss strategy to discard some data packets. At this time, when the data packets are played again, a blurred screen will occur. When the network speed is slow, the frequency of sending data packets will change. Slow, there will be a lot of space left in the buffer, causing waste
