Embodiment 1

[0021] The launch of 4K ultra-high-definition channels in various places marks that the ultra-high-definition industry has officially entered large-scale commercial use, and products in various links such as program production, network transmission, content distribution, TV terminals, and signal monitoring will usher in large-scale upgrades. At the same time, it is difficult for traditional products to fully meet the needs of the current ultra-high-definition industry development. Among them, traditional equipment mainly has the following problems.

[0022] (1) The processing capability of high-definition and 4K programs is limited. In order to improve the processing capability of one or two sets of 4K programs, the cost of the hardware platform is often doubled. In addition, key equipment such as CPU and GPU are updated quickly, and material costs fluctuate greatly.

[0023] (2) The effect of the upper screen display is mediocre, and it cannot truly reflect the superiority of...

Abstract

The invention provides an ultra-high-definition audio-visual program quality monitoring device based on hard decoding, which comprises a stream receiving module, a decoding module, a synthesis outputmodule, an exchange module and a main control module; the stream receiving module is used for acquiring a code stream of an audio / video to be monitored; the decoding module is used for decoding or transcoding the code stream to obtain decoded audio and video data or transcoded audio and video data; the synthesis output module is used for sending the decoded audio and video data to a display end; the main control module is used for accessing the control platform, providing a man-machine interaction function and carrying out recording operation by utilizing the transcoded audio and video data; and the exchange module is used for data exchange among the plurality of modules. The technical problems that in the prior art, the processing capacity for high-definition programs is insufficient, andthe stability is poor are solved.

Description

technical field [0001] The invention relates to the technical field of multi-screen monitoring, in particular to a hardware decoding-based ultra-high-definition audio-visual program quality detection device. Background technique [0002] In the field of multi-screen monitoring, as well as streaming media reception, audio and video codec, audio and video anomaly monitoring, picture synthesis output and other fields, traditional equipment adopts x86 architecture, relying on CPU and GPU to realize decoding, monitoring and display of multi-screen streams Screen. However, the prior art has the technical problems of insufficient processing capability and poor stability for high-definition programs. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a hardware decoding-based ultra-high-definition audio-visual program quality detection device to alleviate the technical problems of insufficient processing capacity and poor stabil...
