Manage device model VS4210, Video decoding module model IT66121.
As preferred technical solution, centralised video processor is controlled by MCU control module, the MCU control module
Upper connection serial ports control module.
The beneficial effects of the utility model are：A, HDMI seamless switching techniques:Audio and video is kept to be established in transmission switches
Link is not disrupted, and PCR is allowed to mark (PTS, DTS) synchronous with the time, makes PCR continuous afterwards before the handover.In audio and video processing
The time is added in frequency processing, ensures that audio output is synchronous with image frame.
B, audio and video splicing:It realizes and multiple HDMI input signal sources diversifications splicing is transmitted to a display eventually
End, is adapted to the application of a variety of varying environments, and can be used for security protection monitoring, and a display terminal can monitor multiple simultaneously
Picture.
C, using serial ports control technology：A kind of on-line software updating is provided, the difference of product according to environment and application makes
User can update equipment software upgrading, support remote control and manual key operational control unit, moreover it is possible to support computer remote
Control operation equipment, provides to user and greatly facilitates.
D, HDMI audio and video treatment technology, embedded audio signal sound picture synchronous correction software technology realize HDMI inputs
The selection of signal source, splicing HDMI Signal separators go out SPDIF audios, belong to innovation in HDMI traditional industries, meet HDMI cities
The demand of field.
