Embodiment Construction

[0072] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0073] Fig. 3 shows a flowchart of a method for controlling playback processing rate of streaming media data according to the present invention. As shown in Figure 3, the streaming media playback processing rate control method according to the present invention comprises the following steps:

[0074] Step S302, monitoring the trend of data saturation of the buffer used to buffer streaming media data in the receiving end, wherein the buffer is a stack of first-in-first-out circular linked list structure; and

[0075] Step S304, adjusting the playback processing rate according to the change trend of data saturation.

[0076] It can be seen from the above description that the present invention provides an idea, because the transmission link should maintain a constant rate as a whole, so the buffer in the receiving end should generally ...

Abstract

The present invention provides a streaming media playback processing rate control method, which is used for controlling the playback processing rate of a receiving terminal to the streaming media data. The streaming media playback processing rate control method is characterized in that the method comprises the following steps: step a, the changing trend of the data saturation of a register used for the registering the streaming media data in the receiving terminal is monitored, wherein the register adopts a first-in first-out stack having circular link list structure; and step b, the playback processing rate is adjusted according to the changing trend of the data saturation. The present invention also provides streaming media playback processing speed controlling device.

Description

technical field [0001] The invention relates to a method and device for controlling the playback processing rate of streaming media data. Background technique [0002] Streaming Media (Streaming Media) generally refers to time-continuous video and audio information, which is processed and displayed by a display device while being received. [0003] With the rapid development of the information society, streaming media technology has played a leading role in Internet media communication. Among them, video on demand, distance education, video conferencing, Internet live broadcast, online news release, online advertisement and other aspects are widely used, which facilitates people's information and emotional exchange on a global scale. [0004] There are mainly two schemes for transmitting multimedia information such as audio and video (A / V) such as downloading and streaming (abbreviated as "streaming") transmission. There are two ways to implement streaming: real-time strea...
