Abstract
The invention discloses an audio/video quality analysis system of a videoconferencing television. The audio/video quality analysis system comprises a television audio/video decoding unit, a television audio/video quality analysis unit, a display unit and a storage unit. The audio/video quality analysis system intercepts audio/video streams by the television audio/video decoding unit, assesses quality of the audio/video streams by the television audio/video quality analysis unit, gathers assessment results by the storage unit and displays the assessment results through the display unit, and operators and maintainers can be helped accurately knot the operating states of the videoconferencing television effectively. Meanwhile, tested conference rooms are organized into testing conferences of the videoconferences, and the on-going videoconferences are not interfered.
Description
Technical field
The present invention relates to a kind of video conferencing audio-visual quality analytical system, belong to the Internet video communications field.
Background technology
Meeting is the important component part of Government and enterprise work, video conference is the novel conferencing occurred cybertimes, it can interconnect field scene real-time for arbitrary for different location meeting-place and voice, there is provided the space of sharing the sense of hearing and vision to participant simultaneously, make the sensation that each side membership user has " face-to-face " to talk.
TV conference system it can save a large amount of travel time, expense for government or enterprise, increase work efficiency, reduce entreprise cost; Can convene and hold a meeting and train at any time, field staff also can pass through the meeting that the Internet participates in company.
Therefore TV conference system becomes the new lover of many government departments or enterprise now, current TV conference system adopts equipment that is domestic or import to set up mostly, but the O&M service pressure of this system is larger, especially audio-visual quality cannot quantitative analysis and advanced processing in operational system, effectively can not ensure the normal use of TV conference system.
Therefore be badly in need of a kind of audio-visual quality analytical system now, quality evaluation can be carried out to audio frequency and video, help the operating state of operation maintenance personnel accurate perception TV conference system.
Summary of the invention
In order to solve the problems of the technologies described above, present invention achieves a kind of video conferencing audio-visual quality analytical system, quality evaluation can be carried out to audio frequency and video, help the operating state of operation maintenance personnel accurate perception TV conference system.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of video conferencing audio-visual quality analytical system, comprises TV audio/video decoding unit, TV audio-visual quality analytic unit, display unit and memory cell; Described TV audio/video decoding unit is in order to intercept the audio/video flow that in tested meeting-place, MCU sends to premonitoring terminal, the audio/video flow of intercepting is converted to the audio/video flow that can play-over, the audio/video flow after conversion is sent to TV audio-visual quality analytic unit; Described TV audio-visual quality analytic unit, in order to receive the audio/video flow after conversion, calls the SDK carried and carries out quality evaluation, by assessment result stored in memory cell to it; Described memory cell is in order to store assessment result; Described display unit is in order to show the assessment result be stored in memory cell.
Described TV audio/video decoding unit adopts the method for Port Mirroring to intercept audio/video flow.
Described TV audio/video decoding unit uses FFmpeg decoding protocol stack to convert the audio/video flow after filtration to can play-over audio/video flow.
The audio/video flow that described TV audio/video decoding unit intercepts is the audio/video flow of H.264 encoding.
The video conference management interface that described video conferencing audio-visual quality analytical system is called in TV conference system sets up tested meeting-place into the testing session independent of video conference.
The beneficial effect that the present invention reaches: the present invention intercepts audio/video flow by TV audio/video decoding unit, by TV audio-visual quality analytic unit, quality evaluation is carried out to audio/video flow, by memory cell, assessment result is gathered, show assessment result by display unit, effectively can help the operating state of operation maintenance personnel accurate perception TV conference system; Tested meeting-place is set up into the testing session independent of video conference simultaneously, can not produce interference to ongoing meeting.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, a kind of video conferencing audio-visual quality analytical system, comprises TV audio/video decoding unit, TV audio-visual quality analytic unit, display unit and memory cell.
The function of each unit is as follows:
TV audio/video decoding unit
The method of Port Mirroring is adopted to intercept the audio/video flow that in tested meeting-place, MCU sends to premonitoring terminal, here audio/video flow is the audio/video flow of H.264 encoding, use FFmpeg decoding protocol stack the audio/video flow of intercepting to be converted to the audio/video flow that can play-over, the audio/video flow after conversion is sent to TV audio-visual quality analytic unit.
TV audio-visual quality analytic unit
Receive the audio/video flow after conversion, call the SDK carried and quality evaluation is carried out, by assessment result stored in memory cell to it.
Memory cell is in order to store assessment result.
Display unit is in order to show the assessment result be stored in memory cell.Operation maintenance personnel can check current audio-visual quality by display unit, also can check audio-visual quality in the past, be convenient to safeguard TV conference system.
The tested meeting-place that above-mentioned video conferencing audio-visual quality analytical system is tested is independently, before starting test, described video conferencing audio-visual quality analytical system is set up tested meeting-place into the testing session independent of video conference by the video conference management interface called in TV conference system, be about to need the conference terminal of test set up into testing session and carry out the independently meeting of opening, by tested meeting-place being set to one by one the real-time audio and video stream that main meeting-place obtains each tested meeting-place one by one, the real-time analysis of audio-visual quality can be realized, interference can not be produced to ongoing meeting simultaneously.
The present invention intercepts audio/video flow by TV audio/video decoding unit, by TV audio-visual quality analytic unit, quality evaluation is carried out to audio/video flow, by memory cell, assessment result is gathered, show assessment result by display unit, effectively can help the operating state of operation maintenance personnel accurate perception TV conference system.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
