Embodiment Construction
[0018] In order to solve the problem that the prior art cannot process a large number of videos in parallel, the present invention provides a multi-channel video signal quality monitoring device. The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0019] Such as figure 1 as shown, figure 1 It is a schematic structural diagram of a multi-channel video signal quality monitoring device according to an embodiment of the present invention.
[0020] The equipment includes: a chassis, one or more DSP (Digital Signal Processing, digital signal processor) processing modules, and one or more hosts. Wherein, the DSP processing module and the host computer can be placed in the chassis. Both the DSP processing module and the host can be plug-in modules of standar...

The invention discloses multi-channel video signal quality monitoring equipment which is characterized in that each video decoding unit is used for decoding video data to obtain a single-frame image sequence and the characteristic value of each frame of image, each signal mode identifying unit is used for identifying a single-frame image with the characteristic value being greater than a threshold value in the single-frame image sequence, each image output unit is used for receiving the single-frame image and acquiring the single-frame image sequence, and if the single-frame image sequence comprises the single-frame image, each image output unit is used for identifying the signal quality information of the single-frame image in the single-frame image sequence, reducing the resolution ratio of the single-frame image sequence and sending the single-frame image sequence carrying the signal quality information to a corresponding host module which is used for splicing the single-frame image sequences into multi-image video data and displaying the multi-image video data. The multi-channel video signal quality monitoring equipment effectively solves the problem of performing parallel processing on a plenty of multi-channel video data. Through performing parallel processing on the multi-channel video data by one or more DSP (digital signal processing) modules, the data processing capability is promoted, the real-time performance is improved, and the energy consumption and the size are reduced.
Description
technical field [0001] The invention relates to the technical field of video processing, in particular to a multi-channel video signal quality monitoring device. Background technique [0002] The existing multi-channel video signal quality monitoring method is to use the server as a video signal quality monitoring device, and cooperate with the operating system and application software to perform parallel decoding and video signal quality analysis on multiple channels of video, so as to realize the monitoring of the quality of each video signal. monitor. However, since the server usually needs to be configured with multiple multi-core CPUs, the parallel processing of multiple channels of video can be realized through application software. However, in the prior art, the number of video channels that can be processed in parallel by a single server is generally 20 channels of standard definition video. With the popularization of video network transmission applications, the nu...
