Problems solved by technology

Adjacent location cameras cannot be seamlessly spliced, and can only be viewed by observing multiple channel images one by one. If the image is corrected on the client side, there will be a very large performance requirement on the client side and the cost will be high.

Embodiment 1

[0048] The present invention provides a multi-channel encoding remote transmission display method, which includes the following steps:

[0049] S1. Obtain a multi-channel video stream;

[0050] S2. Perform splicing and encoding on the multi-channel video stream to obtain a single-channel video stream;

[0051] S3. Decode and play a single channel video stream.

[0052] Further, the step S1 to obtain a multi-channel video stream is achieved by setting up several video capture devices on site.

[0053] Further, in the step S2, the multi-channel video stream is spliced ​​and encoded to obtain a single-channel video stream, which is implemented on the streaming media server set on site;

[0054] In step S2, the multi-channel video stream is spliced ​​and coded to obtain a single-channel video stream and implemented by hardware coding or / and software coding;

[0055] Using hardware coding on the server side can improve coding efficiency and reduce coding requirements for cpu load.

[0056] In t...

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...
