Embodiment 1

[0033] This embodiment provides a secondary video data encoding method, please refer to figure 1 , which is a schematic flow chart of the secondary video data encoding method. Such as figure 1 As shown, the secondary video data encoding method includes the following steps:

[0034] S1, collecting video data. In this embodiment, the video data is compressed data obtained after being compressed by a video compression algorithm, such as H.263, H.264, H.265, AVI, MPEG4, and the like. And use the standard compression algorithm to decode the compressed video data into video data in YUV format. The video data in YUV format is the original video source data captured during video collection, mainly composed of three components of YUV.

[0035] S2. Decode the collected video data in a first predetermined manner to obtain first image data. The first predetermined manner includes: decoding the collected video data in a video stream format. In this embodiment, the data in the standard...

Embodiment 2

[0044] This embodiment provides a secondary video data encoding system 1, please refer to figure 2 , is shown as a schematic diagram of the principle structure of the secondary video data coding system. Such as figure 2 As shown, the secondary video data encoding system 1 includes: an acquisition module 11 , a first processing module 12 , a second processing module 13 , and a transmission module 14 .

[0045] The collection module 11 is used for collecting video data. In this embodiment, the video data is compressed data obtained after being compressed by a video compression algorithm, such as H.263, H.264, H.265, AVI, MPEG4, and the like. And use the standard compression algorithm to decode the compressed video data into video data in YUV format. The video data in YUV format is the original video source data captured during video collection, mainly composed of three components of YUV. In this embodiment, the acquisition module may be a front camera on a security monitori...

Abstract

The invention provides a secondary video data coding method. The method comprises following steps of: coding acquired video data in a first preset way so as to acquire first image data; coding the acquired image data in the YUV format in a second preset way so as to acquire second image data; and carrying out network transmission on the second image data. According to the invention, it is achieved that video resolution is unchanged and transmission error rate is reduced; video viewing effects are ensured; transmission cost is quite low; and high-quality requirements required for the monitoring are met.

Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to an encoding method and system, in particular to a secondary video data encoding method and system. Background technique [0002] At present, the security video surveillance industry is developing rapidly, and people's requirements for video quality are getting higher and higher. For example, the image captured by the image acquisition device is developing from D1 resolution to 720P, or even 1080P resolution. The direct benefit of this is that people can get a clear front-end image. But the ensuing problem is the problem of transmission. [0003] In terms of video transmission, the higher the high-definition video, the higher the bit rate, that is, the larger the amount of data transmitted per unit time. In this way, under the same bandwidth conditions, the number of video monitoring channels that can be transmitted is less. Even under certain bandwidth conditions, the v...
