Embodiment Construction

[0021] The present invention designs an efficient streaming media on-demand program based on the UDP protocol. According to the feature of playing on-demand files, the program adopts the strategy of not caching the data that has been sent, which greatly saves server resources.

[0022] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0023] figure 1 It is a schematic flow sheet of the method of the present invention, and the specific steps of the method are as follows:

[0024] Step S1: Create a video file on the server, the video file includes several data frames, each data frame corresponds to a frame sequence number and a frame time stamp; where the data frame can be a video frame or an audio frame.

[0025] combine figure 2 As shown, it is a diagram of the serial number of the data frame, the length of the data frame and the timestamp of the corresponding frame of the local video file on the se...

Abstract

The invention relates to a streaming media transmission method on the basis of a UDP data transfer protocol. The method comprises the following steps: establishing a video file at a server side, wherein the video file comprises a plurality of data frames, and each data frame corresponds to a frame serial number and a frame timestamp; segmenting each data frame into a plurality of data packets or combining a plurality of the data frames into one data packet, wherein each data packet corresponds to a packet serial number and a packet timestamp; sending the data packets to a client side and recording the packet serial number and the packet timestamp of each data packet into a queue in an internal storage via the server side; detecting whether the data packets are lost via the client side, if yes, feeding back the serial numbers of the lost packets to the server side, and then finding out the corresponding packet timestamps via the server side according to the packet serial numbers in the queue; and according to the relation between the packet timestamps and the frame timestamps, finding out the corresponding data frames of the lost data packets, segmenting one data frame into a plurality of the data packets or combining a plurality of the data frames into one data packet and then sending the lost data packets to the client side.

Description

technical field [0001] The invention relates to the field of wireless streaming media, in particular to an efficient streaming media transmission method. Background technique [0002] With the rapid development of mobile communication technology and video compression methods, the technology of transmitting real-time video streams over wireless IP networks has attracted people's attention. Transmission errors such as packet loss and timeout may occur when data is transmitted in a wireless IP network and a best-effort Internet. The value of the packet loss rate is generally small, but it has a great impact on the user, and it is a killer that affects the video quality, especially the compression ratio currently used is relatively high. The loss or damage of a video frame will also affect other related frames. Decompression directly damages the fluency and clarity of video playback at the receiving end. Therefore, error control processing for transmission needs to be performe...
