Description
Technical field
The present invention relates to mobile Internet and communication technical field, more particularly to television set and machine are realized by USB interface
The device and method of top box Synchronization Control.
Background technology
Digital video switching box（English：Set Top Box, abbreviation STB）, box on so-called Set Top Box or machine is one
The equipment of individual connection television set and outside source.The data signal of compression can be changed into television content by it, and in television set
On show.Signal can come from wire cable, satellite antenna, broadband network and terrestrial broadcasting.It is interior that Set Top Box is received
Hold in addition to image, sound that simulated television can be provided, be more can to receive digital content, including electronic programming refers to
South, internet webpage, captions etc..Enable users to watch digital television program on existing television set, and can be entered by network
The amusement of row interactive digitalization, education and commercialization activity.
Set Top Box modules in the high-peed connection of Internet, collaborative work.User first please by sending order
Seek a URL.In a process of exchange using PPP point-to-point protocols, the order eventually arrives at the offer of Internet business
In the modem common frame of person.Then by dynamic allocation method, the user obtains the IP address used in this transaction,
And Internet is sent in request.After the content of Internet is found, the offer of Internet business is then sent to
Person（ISP）There, then by the router of ISP it is responsible for being sent to cable television network, eventually passes back to the Set Top Box of user.Having
The Set Top Box of line TV, the information content is trapped.Set Top Box completes the task of a gateway between television set and cable system.
Its task is the communication flows for managing IP, once the ability IP bag arrival Set Top Box with control user's turnover network, regarding
Frequency signal is separated from the bag, and to data therein row decoding is entered, and is then sent to prepare in television set browser
Upper display.
The course of work of DTV STB：DTV STB selects channel by Network Interface Module, goes forward side by side
Row demodulation channel decoding process, exports MPEG-2 MPTS data, gives demultiplexer, and demultiplexer is from MPEG-2
Extract the video and audio basic flow packed of a program in transmission flow data out（PES）Data, including set-top box video PES, sound
Frequency PES and assistance data PES, include a descrambling engine in demultiplexer, data that can be in transport stream layer and PES layers to scrambling
Descrambled, demultiplexer output is video and audio PES for having descrambled.Video PES sends into Video Decoder, takes out MPEG-2 and regards
Frequency according to and after decoding it, output to analog encoder is encoded into analog video signal, then the output of Jing video output circuits.
Audio frequency PES sends into audio decoder, takes out MPEG-2 voice datas and decodes it, and output PCM audio data to audio frequency D/A becomes
Parallel operation, audio frequency D/A converters output analog stereo audio signal, the output of Jing audio output circuits.
Only audio-video signal is transmitted by audio-video interface between Set Top Box and television set, respective state letter is not provided
Breath, therefore Set Top Box and television set are in open and close machine, and respective remote control is used respectively, or respective power switch is pressed,
It is cumbersome.A kind of miniaturization network machine top box is have also appeared on existing market（Be otherwise known as HDMIDongle, HDMI intelligence electricity
Depending on rod, MINIPC etc.）, the equipment allows user it to be directly inserted on the HDMI input interfaces of television set, same to television set
Composition one, allows television set to become as internet intelligent TV at once, but because the equipment is now hidden in behind television set, its work
Making state cannot recognize, and easily cause the machine of opening by mistake or the state do not shut down for a long time；To cause the waste of power supply, meanwhile, cause to IP
