Problems solved by technology

[0023] The above video quality assessment method uses the packet header information of the RTP packet to calculate the packet loss rate, and uses the loss rate to calculate the video quality, which reduces the complexity; because it only considers the packet loss rate, the calculation is simple but the accuracy is low

Embodiment Construction

[0062] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0063] The no-reference video quality assessment model can use network information, network data packets and information of the video stream itself to evaluate the quality of the video stream. If the video stream can be completely analyzed, the evaluation will be more accurate. However, due to the high complexity of analyzing the video stream, This makes video quality evaluation impossible in real time or unsuitable for terminal devices (network devices, test device...

Abstract

Embodiments of the invention disclose a video data quality assessment method and an apparatus thereof. The video data quality assessment method comprises the following steps: acquiring a compression distortion parameter of video data; acquiring a frame damage distortion parameter; calculating a video quality parameter according to the compression distortion parameter and the frame damage distortion parameter, wherein the video quality parameter is a difference value of the compression distortion parameter and the frame damage distortion parameter.

Description

technical field [0001] The invention relates to the technical field of digital signal processing, in particular to a video data quality evaluation method and device. Background technique [0002] With the development of network technology, video-on-demand, Internet TV, videophone, etc. have become the main services of the broadband network, and these services will also become the main services of the third generation (3G, the 3rd Generation) wireless network. In order to reduce the resources occupied during video signal storage or transmission, the video signal is compressed at the sending end and then transmitted to the receiving end, and the receiving end restores the video signal through decompression processing and plays it. [0003] The quality of network video is affected by many complex factors, such as: the quality of service of the transmission channel, the adaptation of video codec parameters to the transmission channel, the location of video data loss caused by ch...
