Abstract
The invention relates to a high definition loop court trial direct broadcast host belonging to the network court trial direct broadcast technology field. The host provided by the invention comprises a coding and decoding processor, a video decoding circuit, an audio decoding circuit, and a storage circuit. The video decoding circuit and the audio decoding circuit are respectively connected with the input end of the coding and decoding processor, and the output end of the coding and decoding processor is connected with an audio/video output interface. The communication end of the coding and decoding processor is connected with a 485 interface. The high definition loop court trial direct broadcast host is advantageous in that the functions such as the audio/video loop, the audio/video coding network fluidization, the image synthesis, the audio gain control, the audio noise suppression, and the friendly user control client can be provided by one device, and therefore the current court trial host of the court can be fully used or even replaced, and therefore the court trial direct broadcast can be realized quickly.
Description
Technical field
The present invention relates to the logical live court's trial main frame of a kind of high definition ring, belong to network live court's trial technical field.
Background technology
Along with country accelerates the paces of trial open, public network live court's trial becomes inevitable trend.But the existing court's trial main frame of law court, unit type is various, if unifying to the live platform of same public network, relating to and carrying out software docking with each manufacturer, wasting time and energy very much.It is therefore desirable to a simple and effective equipment, it is possible to make full use of the existing court's trial main frame of law court or even replace, thus quickly realizing public network live court's trial for law court.
Summary of the invention
The invention solves the problems that and technical problem is that: the shortcoming overcoming above-mentioned technology, it is provided that one quickly realizes the logical live court's trial main frame of law court's public network live court's trial high definition ring.
In order to solve above-mentioned technical problem, the technical scheme that the present invention proposes is: the logical live court's trial main frame of a kind of high definition ring, including: codec processor, video decoding circuit, audio decoding circuit and storage circuit；Described video decoding circuit, audio decoding circuit connect the input of described codec processor respectively；The outfan of described codec processor is then connected to audio and video output interface；The communication ends of described codec processor is connected to 485 interfaces.
Such scheme is further improved by: the communication ends of described codec processor is also associated with RJ45 interface and USB interface.
Such scheme is further improved by: described video decoding circuit includes the sdi signal decoder that 4 route GV7601 chips are constituted.
Such scheme is further improved by: described audio decoding circuit is the audio decoder being made up of AIC23B chip.
Such scheme is further improved by: described audio and video output interface is USB interface.
Such scheme is further improved by: described codec processor is also associated with the SD card reader being made up of chip RTS553.
High definition ring provided by the invention leads to live court's trial main frame；Achieve that an equipment solves that the ring of audio frequency and video is logical, the coding network fluidisation of audio frequency and video, picture synthesis, audio gain controls, audio noise suppresses, friendly user controls client, such that it is able to make full use of the existing court's trial main frame of law court or even replace, quickly realize law court's public network live court's trial.
Accompanying drawing explanation
Fig. 1 is one preferred embodiment structural representation of the present invention.
Detailed description of the invention
