Embodiment 1

[0029] Below to figure 1 As an example, the method for controlling the transmission rate of streaming media provided by Embodiment 1 of the present invention is described in detail. figure 1 The flow chart of the method for controlling the sending rate of streaming media provided by Embodiment 1 of the present invention. In the embodiment of the present invention, the subject of implementing the following steps may be a streaming media server, or the application module loaded in the streaming media server may implementation, but not limited thereto, the following will take the streaming media server as the subject of implementation in detail. Such as figure 1 As shown, this embodiment specifically includes the following steps:

[0030] Step 101, acquire the sending time corresponding to the current data message of the streaming media sent by the streaming media server.

[0031] Wherein, the sending time corresponding to the current data message refers to the time when the s...

Embodiment 2

[0049] In addition, the second embodiment of the present invention provides the principle of dynamically compensating the streaming media rate, so as to make the technical solution of the method provided by the foregoing embodiments of the present invention more clear. figure 2 It is a schematic diagram of the principle of dynamically compensating the streaming media rate in the method for controlling the streaming media transmission rate provided by Embodiment 2 of the present invention. Such as figure 2 As shown, the horizontal axis represents time, and the width between the dotted lines on the horizontal axis represents the timing interval for sending data packets, which is ΔT=L / R, where L is the length of the data packets sent each time, and R is the message sending rate.

[0050] In case a), a data packet is sent at Ta1 time, and due to some reason (such as the streaming media server CPU overload in a large concurrency scenario), the delay of the timer takes effect, at...

Embodiment 3

[0055] In addition, Embodiment 3 of the present invention also provides a device for controlling the sending rate of streaming media, which is used to implement the method for controlling the sending rate of streaming media in the foregoing embodiments of the present invention, and the device may be located in a streaming media server. image 3 A schematic diagram of a device for controlling the transmission rate of streaming media provided in Embodiment 3 of the present invention, as shown in image 3 As shown, the device provided by the embodiment of the present invention includes the following functional units:

[0056] The obtaining unit 301 is configured to obtain the sending time corresponding to the current data message of the streaming media sent by the streaming media server.

[0057] Wherein, when the length of the data message sent by the streaming media is set to be L each time, according to the attributes of the video corresponding to the streaming media, such as ...

Abstract

The invention relates to a method and device for controlling the sending rate of streaming media. The method comprises the following steps: a sending moment corresponding to a current data message, which is sent by a streaming media server, of the streaming media is acquired; an actual time interval between the sending moment corresponding to the current data message and a sending moment corresponding to a previous data message of the streaming media is calculated; if the actual time interval is not equal to a preset time interval, a time interval between the sending moment corresponding to the current data message and a sending moment of a next data message of the streaming media is regulated, so that the sending moment corresponding to the next data message is a preset sending moment of a next message. By means of the method and device for controlling the sending rate of the streaming media, the effect that dynamic compensation is conducted on the sending rate of the streaming media by means of regulating the sending time interval of the streaming media in real time is achieved.

Description

technical field [0001] The invention relates to the field of network multimedia technology, in particular to a method and device for controlling the transmission rate of streaming media. Background technique [0002] With the rapid development of computer technology, streaming media applications are getting more and more attention. At present, most streaming media services are carried based on Hyper Text Transfer Protocol (Hyper Text Transfer Protocol, HTTP). In the streaming media service based on HTTP, progressive download is the mainstream solution, which downloads media files directly through the HTTP protocol, or provides streaming services by playing while downloading. Wherein, the method of playing while downloading is to continuously send the media file to the playback terminal, and the terminal plays a part of the content of the media file that can be played. [0003] In various streaming media applications, such as video on demand (Video On Demand, VOD), interact...
