Problems solved by technology

Due to changes in the wireless environment, the transmission delay from the sending end to the receiving end will fluctuate, but the decoder at the receiving end will not perform packet sending control according to the change in transmission delay after buffering the data, so the change in transmission delay will continue to the decoding During the processing, it may cause the receiving end to fail to play the video smoothly when playing the video after decoding and processing, which will affect the quality of the video playback, such as causing stuttering and other phenomena

Embodiment Construction

[0020] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0021] In this application, the location of the buffer is as figure 1 As shown, the buffer is located between the RTP layer and the decoder layer, and is responsible for buffering the RTP data packets, and sends the RTP data packets to the decoder for processing according to a certain outbound control policy. The size of the cache space can be statically set to a fixed value, or dynamically allocated according to actual device capabilities. The RTP data packets of audio and video can be divided into two buffers for buffering, and the amount of audio data will be significantly smaller than the amount of video data in the same period of time. This application mainly describes the buffering and sending of video data. For synchronous audio data, the corresponding a...

Abstract

The invention discloses a data processing method in video service. The method comprises that a reception end sends received video RTP packets to a video buffer; the video buffer sends the cached video RTP packets to a decoder for processing; and processing results of the cached RTP packets belonging to the same video frame are sent to the decoder at the same time. Thus, the video play quality can be improved.

Description

technical field [0001] The present application relates to communication technology, in particular to a data processing method in video services. Background technique [0002] The video service can be transmitted in the wireless network. Specifically, at the sending end, the device compresses and codes the video data to be transmitted and then transmits it to the receiving end through the transmission channel; the receiving end receives the compressed data sent by the sending end , decode it and play it to the user. Transmission delay occurs during transmission from the sender to the receiver. [0003] In the prior art, the specific processing after receiving the video data at the receiving end includes: after receiving the data, the receiving end will send the received RTP packet data to the decoder for processing, and the front end of the decoder includes a processing buffer, which can input the The RTP packets are cached, and then the cached data is decoded. At present,...
