Abstract

The invention discloses a multichannel coding remote transmission display method. The method is characterized in comprising the steps of S1, obtaining multichannel video streaming; S2, splicing and coding the multichannel video streaming to obtain single-channel video streaming; S3, decoding and playing the single-channel multichannel video streaming, wherein the S1 of obtaining the multichannel video streaming is realized through a plurality of video collection devices arranged on site, the S2 of splicing and coding the multichannel video streaming to obtain the single-channel video streaming is realized through a streaming media server arranged on site, and the S3 of decoding and playing the single-channel multichannel video streaming is realized at a client. The method has the beneficial effect that after obtaining the multichannel video streaming, the streaming media server splices and codes multichannel images requested by the client and then forwards the images, so only one way of video streaming is transmitted between the streaming media server and the client, the video data is greatly reduced, a demand for bandwidth is greatly reduced, and a cost is greatly reduced.

Description

Technical field

[0001] The invention relates to the field of video coding transmission, in particular to a method and system for multi-channel coding remote transmission display Background technique

[0002] In the field of video capture or playback technology such as live broadcast or on-site monitoring, it is usually necessary to use long-distance transmission technology, configure several video capture devices at the front end, and transmit the video data collected by the video capture devices to the central control room or monitoring room through the network. Play the images captured by the video capture device through the playback device. When there are many video capture devices on the front end, and users turn on multiple video channels at the same time, there will be a large amount of video data that needs to be transmitted on the network, which will occupy a huge network bandwidth and costly. When a user views 4 video streams at the same time, if each video stream occup...
