Embodiment Construction

[0030] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] Such as figure 1 As shown, it is a schematic flow chart of the steps of the data transmission method in Embodiment 1 of the present invention. It can be seen from the figure that the method includes the following steps:

[0032] Step 101: judging whether the amount of data in the buffer of the current receiving end is within the set value range, that is, whether the amount of data is greater than the first threshold value, or less than the second threshold value, if not, repeat this step, Otherwise, go to step 102.

[0033] The change of network channel quality can be regarded as a non-linear change, which may cause the amount of data received by the receiving end to change, and the amount of data in the buffer of the receiving end to change. In order to ensure that the receiving end can play streaming media data normally, two thresholds are p...

Abstract

The invention discloses a method for transmitting data in streaming media service, which comprises the following steps: detecting data quantity in a buffer area of a current receiving end, and determining that the data quantity is greater than a first threshold or smaller than a second threshold, wherein the first threshold is greater than the second threshold; sending alarm information to a sending end, wherein the alarm information shows that the data quantity in the buffer area is greater than the first threshold or smaller than the second threshold; and adjusting the data quantity transmitted to the receiving end in unit time by the sending end according to the alarm information, and transmitting data according to the adjusted data quantity. The method makes the receiving end and the sending end timely respond to the change of data transmission quantity caused by the change of the quality of network channels so as to ensure the normal execution of the streaming media service. The invention also discloses a system for transmitting data in streaming media service, a data sending device and a data receiving device.

Description

technical field [0001] The invention relates to data transmission technology in the field of communication, in particular to a data transmission method, system, data receiving device and data sending device in streaming media services. Background technique [0002] With the rapid development of wireless networks, streaming media services have become an important development direction of data services. Multimedia video telephony and online playback are typical applications in streaming media services. However, in the actual wireless network environment, channel quality often changes. For example, when a terminal enters an environment with poor network signals from a normal environment, the transmission capacity of the bandwidth will decrease; when the number of terminals in the same cell increases sharply, It will cause the network load to increase, and the channel width allocated to each terminal will decrease, etc. When the channel quality changes drastically (such as when...
