Embodiment Construction
[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0022] The present invention is divided into two parts, one part is the data processing of the sorting unit, which processes the data into a continuous data stream and sends it to the downstream decoder part. The other part is the buffer control and time stamp judgment algorithm of the decoder to smoothly output the code stream to ensure that the image can be played according to the normal effect.
[0023] A method for stably outputting media data in an embodiment of the present invention is as follows: figure 1 shown, including the following steps:
[0024] Step s101, receiving media data, and sorting the media data according to the serial numbers of the data packets of...

The invention discloses a stable output method of media data. The method comprises the following steps: A. receiving the media data, and sequencing the media data according to the serial number of data packet of the media data; B. storing the sequenced media data into a public buffer zone; C. determining the output time point of the data frame, and outputting the data frame at the time point, according to time stamp information of a data frame of the media data in the public buffer zone. The invention also discloses a stable output device of media data. The invention sequences according to the serial number of the data packet of the received media data, and determines the method of the output time point of the data frame according to the time stamp information of the data frame of the media data, thus solving the image processing problem of a television wall image decoder, leading the image output to be stable, simultaneously causing no long delay, and meeting the requirements of monitoring of the existing monitoring real-time television wall.
Description
technical field [0001] The invention relates to the technical field of video monitoring and communication, in particular to a method and device for stably outputting media data. Background technique [0002] At present, monitoring has entered the era of digitalization, because the monitoring front-end basically adopts ADSL (Asymmetric Digital Subscriber Line, Asymmetric Digital Subscriber Line) connection, and some use wireless access. In the process of network transmission, multimedia data has various situations such as jitter, delay, and out-of-sequence. Finally, image problems such as image jumps, frame skipping, and blurred screens will appear in subsequent decoders, resulting in problems in the final real-time monitoring. Especially in scenarios such as TV walls that require high real-time display, the requirements for images are even higher. [0003] At present, the image processing of many decoders is carried out by increasing the delay, which may be increased to 2-3...
