Video frequency broadcast quality detecting method for medium broadcast terminal device

Abstract

The present invention discloses media playing terminal unit video playing quality test method. It contains A1, assigning different sequence of frames number to each video frame of media file, determining said sequence of frames number corresponded different graphic marking, overlapping said graphic marking to media file corresponded video frame; A2, using said media file as testing source transmitting to media playing terminal unit; A3, said media playing terminal unit decoding and outputting said media file code stream, A4, in turn identifying outputted graphic marking in video frame and generating corresponded frame serial number, analyzing said frame serial number, evaluating video playing quality. The present invention solves media playing terminal unit video playing volubility automatic test.

Description

technical field [0001] The invention relates to the technical field of IP television, in particular to a method for testing video playback quality of a media playback terminal device. Background technique [0002] At present, IP TV has become a new market growth point in the telecommunications field. Providing video services to users through streaming media services carried on IP networks will become an important development direction of TV entertainment in the future. Various media playback terminal equipment such as IP-STB (IP- Set Top Box, IP set-top box) and so on have also become hot spots in the development of terminal products, but how to test the playback quality of media playback terminal equipment has become a new problem. [0003] The playback quality of media playback terminal equipment covers two aspects. One aspect is the picture quality (including picture clarity, color, deformation, distortion, noise, interference, etc.). The emergence of digital video techno...

AI Technical Summary

Problems solved by technology

[0006] 1. It can only be used to test the damage of picture quality, and cannot effectively test real-time problems such as picture pause delay and frame loss;

[0007] 2. It is suitable for the situation where codecs appear in pairs, and it is not very suitable for testing decoding equipment such as video media terminals;

[0008] 3. The video used for testing must be a specified video stream, and its quantity and type are limited, so it will inevitably limit the selection range of video streams, and cannot apply to the test requirements of different encoding formats, resolutions, and stream rates

The disadvantages of subjective observation are: it is difficult for human subjective judgment to accurately reflect the playback situation, such as the judgment of a certain time delay or the ignorance of a certain error, etc. It is easy to cause errors; the observation time is long, wasting manpower and resources; for frame loss, Problems such as out-of-sequence are even more difficult to detect, and it is difficult to find and count

[0010] At present, there are no relevant tools and methods for testing the playback fluency of media playback terminal equipment.
