Abstract

The invention discloses a method and a device for adjusting the streaming media bit rate, relating to the field of communication. The invention is invented for solving the problem of poor efficiency in the process of adjusting the streaming media bit rate in the prior art in real time. The method provided by the embodiment of the invention comprises the following steps of: periodically inquiring data amount of a sending buffer area, and switching the bit rate of a video track according to the change of the data amount of the sending buffer area, thereby changing the rate of writing data to the buffer area, enhancing the quality of network transmission, and enhancing the audio and the video experience effect. The invention is suitable for communication systems.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for adjusting the code rate of streaming media. Background technique [0002] The current audio and video streaming service adopts multi-bit rate technology. The same service content is set on audio and video tracks with different bit rates, and the streaming media server dynamically selects audio and video tracks with different bit rates for transmission according to the user's real-time bandwidth. stream media. When the user's available bandwidth is too low, choose low-bit-rate streaming media transmission to avoid transmission packet loss and ensure users can play smoothly; when the user's available bandwidth increases, choose high-bit-rate streaming media transmission to improve the user's audio and video experience. [0003] However, there are at least two existing ways to adjust the bit rate of streaming media in real time according to the actual situation ...
