Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. figure 1 It is a schematic diagram of the cloud transcoding device. The device is applied on a host computer and includes a split unit, a transceiver unit and an integration unit. in:

[0015] The segmentation unit divides at least part of the source video stream into several GOP sequences according to preset rules, and each GOP sequence includes a sequence number and at least one GOP;

[0016] The transceiver unit sends the divided GOP sequence to each auxiliary node for transcoding, and then receives the transcoded GOP sequence from each auxiliary node;

[0017] The integration unit sorts and combines the transcoded GOP sequences according to sequence numbers, and integrates them into a transcoded video stream.

[0018] In the present invention, the transcoding efficiency is no longer solely dependent on improving the hardware or s...

Abstract

The invention provides a cloud transcoding device which is used in a video transmitting system; the device comprises a cutting unit, a transmitting-receiving unit and an integrating unit; the cutting unit cuts a source video into a plurality of GOP (group of pictures) sequences; the transmitting-receiving unit transmits the cut GOP sequences to each assistant node and then receives the transcoded GOP sequences from each assistant node; and the integrating unit integrates the transcoded code stream again. By adopting the method and the device provided by the invention, the performance requirement of fast mass transcoding is met with relatively low investment and maintaining cost, the high flexibility and the high reliability are provided, and further, the resource utilization rate is improved.

Description

technical field [0001] The present invention relates to video surveillance technology, in particular to a cloud transcoding method and device. Background technique [0002] Intelligent, high-definition is the development direction of the current video surveillance system, and users' requirements for video surveillance products are also constantly improving, including the clarity of video images, stable performance, rich device types and video formats, and these devices must also run on different types of networks. Therefore, in order to meet these requirements, a large number of transcoding requirements such as video bit rate, frame rate, resolution, codec standard, and video container standard must be involved. Transcoding is a highly computationally intensive signal processing process that requires high computational resources. Therefore, how to improve the processing efficiency of massive transcoding in the video surveillance system is a practical problem that needs to ...
