Description

A kind of acquisition methods and network element device of video tastes evaluation result

Technical field

The present invention relates to the acquisition methods of field of communication technology more particularly to a kind of video tastes evaluation result and Network element device.

Background technology

The progress of the communication technology and multimedia technology makes IPTV (Internet Protocol Television, network Protocol TV), visual telephone, video conference, the network video services such as video on demand are rapidly developed.Meanwhile it is diversified Magnanimity terminal equipment has been deep into each corner of people's life, and people can enjoy abundant network video and be taken in small doses at short intervals whenever and wherever possible Business, video flow have occupied the overwhelming majority of network flow, everything all shows the great vigor of Video service, has wide Market prospects.Industry has started the tide for greatly developing video traffic.

The key problem of Video service is user experience, and service provider must grasp the actual experience information ability of user It is best understood from current service scenario, orientation problem, and then improves service, to promote competitiveness.And the development of these work Dependent on the accurate evaluation to user experience quality (Quality of Experience, QoE).VMOS(Video Mean Opinion Score, video Mean Opinion Score) index is index most crucial in video QoE evaluation, it is to weigh video quality good Bad sole criterion, therefore use without with reference to the accurate calculating of objective method and using VMOS indexs, i.e. video tastes score, for Ensure that user video service quality is significant.

In Video service, the input of VMOS evaluation methods is generally video flowing or player feedback parameter, for user It is current mainly to use player feedback method for interactive operation parameter.Application within the scope of non-VMOS evaluation methods, user The source of interactive operation parameter generally also derives from player and feeds back.

The event information fed back from player can obtain user interactive operation parameter very accurately, can use broadcasting The method is very outstanding in the scene of device feedback.Player feedback method mainly faces following problem：One, it is played not open The method is unavailable in the scene of device feedback capability：There is the case where not allowing using player feedback interactive operation parameter； In the application of VMOS methods, all parameter acquiring sources for considering dimension should be identical, currently be divided into practical applications Two class of player feedback method and code stream analyzing method.Using player feedback method can to the deployment of method, to other dimensions The acquisition of parameter affects：Two, deployed position is limited：Player feedback method is used to make the deployment of entire VMOS methods only Can be confined in terminal, and viewing experience dimension therein should can be evaluated and tested in head end, network, terminal it is different to embody The change information of steaming transfer realizes that failure delimits the target of positioning on network site, therefore cannot be confined to terminal；Even if three, Be be confined in terminal and player feedback capability open, use player feedback method that can also make video source parameter and viewing There are problems for the acquisition of experience parameter：(1) video source parameter acquiring is imperfect：Such as the quality point needs pair of evaluation VBR code streams Code stream depth is decoded to obtain coding parameter, and current player is confined to type of coding, code check, resolution about video source parameter Rate, frame per second etc. are not related to depth decoded information, and only using all methods of these parameters currently all can not correctly evaluate VBR codes Stream；(2) viewing experience parameter acquiring is imperfect：Player method is about the viewing experience parameter (flower that viewing experience parameter can refer to Screen, interim card) interim card can only be fed back by event information, and cannot feed back due to influence caused by packet loss, such as flower screen.

How method shown in embodiment for a better understanding of the present invention realizes that VMOS indexs carry out to network element device below Explanation：

For VMOS indexs, tradition is generally evaluated from two dimensions without reference method：

(1) video source quality：That is the compression quality of film source is related to type of coding, resolution ratio, frame per second, code check, quantization parameter Etc. film sources attribute；

(2) viewing experience：I.e. the picture Damage Evaluation as caused by network transmission, it is related to the videos such as flower screen, frozen frame, interim card Picture visual signature.

VMOS evaluation methods are made of VMOS Computational frames and parameter acquiring method, and the division of labor is：

VMOS Computational frames：The dimension for formulating evaluation, assuming that parameter needed for the scoring calculating of each dimension has existed Under the premise of, to be fitted scoring formula as objective close to subjective testing data, calculate the scoring of each dimension, and finally comprehensive To overall score.

Parameter acquiring method：The input in practical business is analyzed, obtains calculating each dimension scoring in VMOS Computational frames Whole parameters of required each dimension.

From the foregoing, it will be observed that the premise that parameter acquiring method, which is Computational frame, to be used.The design of VMOS Computational frames is general all reasonable By or frame of the practical basis as guidance, either conventional frame, or current newest frame, or even the following more various dimensions, While continuous expansion evaluation dimension is to approach user's actual experience, the problem of all suffering from parameter availability, therefore parameter obtains Method is taken to restrict the practical application of VMOS evaluation methods.

The parameter acquiring of two dimensions in traditional VMOS frames has currently had compared with based on multi-method, therefore most The parameter acquiring problem of the interaction operation experience increased newly in new frame starts that industry is caused to be paid attention to, and needs to be taken according to actual video Input in business carries out the acquisition of this relevant parameter.

Except VMOS methods, the extraction of interactive operation parameter also has important use, such as the operation behavior of counting user Deng.

The evaluation of nearest VMOS further develops, and has merged and has more considered dimension, such as U-vMOS (User, Unified, Ubiquitous-video Mean Opinion Score, user, unified, universality video quality Mean Opinion Score).

U-vMOS increases the evaluation of operating experience on traditional two evaluative dimensions, i.e., user is during watching video For the experience of interactive operation：

It is related to original upload (program request scene)/channel switching duration (live scene), reorientation (i.e. time shift) (in program request Want to reposition play position), pause and restore (in program request), the user's operations behavior such as fast forwarding and fast rewinding (in program request). This new evaluation frame is more complete, can more reflect the actual experience of user comprehensively, and industry is guided to carry out commenting for more various dimensions Valence.In interaction, parameter is weighed with duration information.
