Embodiment Construction

[0018] In the playback service of video surveillance (that is, to play the stored historical multimedia data), a playback server is usually required to provide services for terminal devices. In the playback service, the so-called channel refers to a video stream stored by a camera on a network storage device. At present, when the mobile terminal performs multimedia playback, the playback server will send the video streams of each channel to the client on the mobile terminal (which can be understood as a video surveillance terminal software) and send historical multi-video stream data. If the client needs to play back multiple video streams of N channels, assuming that each channel needs to occupy a bandwidth of 1 Mbps, the user needs to perform N playback operations, and the total traffic required needs to be N Mbps. Assuming that the user performs an average of half an hour of 4-channel playback every day, the traffic consumed by it is 1800×4×1M / 8=900MB traffic, and the month...

Abstract

The invention provides a customized playback device of video streams and a customized service method of the video streams. According to the whole solution, the customized service method of the video streams comprises the following steps that (1) a user applies for a virtual channel, and correspondingly appoints n actual channels; (2) a server correspondingly creates the virtual channel according to the application of a mobile terminal, and returns a virtual channel identification back; (3) the mobile terminal sends a playback request aiming at the virtual channel to the server; (4) the server obtains video streams of the n actual channels after receiving the playback request of the virtual channel, carries out speed reduction processing on the n video streams after carrying out decoding on the n video streams, carries out coding again to form one synthesized speed-reduced video stream, and sends the synthesized speed-reduced video stream to the mobile terminal; (5) the mobile terminal carries out decoding on the synthesized speed-reduced video stream after receiving the synthesized speed-reduced video stream, and carries out display on the synthesized speed-reduced video stream. Compared with the prior art, the customized playback device of the video streams and the customized service method of the video streams can enable the user to conveniently use the mobile terminal to watch the video steams of a plurality of channels through a customized playback service, and can save a large number of traffic fees for the user.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a video stream customization service method and a customization playback device. Background technique [0002] With the rapid development of mobile access technology and mobile terminal technology, people are eager to obtain information and services conveniently from the Internet anytime, anywhere or even while moving, and the mobile Internet emerges as the times require and develops rapidly. The video surveillance industry is no exception. The mobile terminalization of video surveillance clients (such as smart phones) is an inevitable trend of technological development. [0003] Please refer to figure 1 The typical networking structure, the current multimedia (audio and video) playback technology has been widely used in security monitoring systems. Assuming that a user using a mobile terminal needs to play back audio and video of multiple channels at the same time, ...
