Background technology

The IPTV terminal is a kind of conversion equipment that digital television signal is converted to analog signal; But the signal source interface of most of service terminals has only one; And must be connected use with fixing cable, therefore limit the scope of application and the usage quantity of service terminal, and in the home network several kinds of medias such as telephone wire, coaxial cable, power line can have been arranged all at present; Because the communication between them remains separate; If the interface that is provided with one by one as shown in Figure 1, then existing needs knob-and-tube wiring, problems such as wiring complicacy.

The utility model content

There are problems such as signal source is limited, high at the inner integrated various information source modular converter cost of IPTV service terminal, the household internal wiring is complicated, difficult in maintenance in the utility model when having only one or two independent signal source interface to ordinary numbers IPTV service terminal product in the current market; And based on the popularization and the application of Ghn standard criterion; A kind of novel I PTV service terminal based on Ghn is proposed; The user can make full use of any media in the existing home network wiring as information source channel; Be converted into the needed signal source of IPTV service terminal CPU module through the Ghn module; Thereby enlarged the information source channel of IPTV service terminal; Simplified the network layout of household internal; Reduced user's use cost, for reaching this purpose, the utility model provides a kind of IPTV terminal based on the Ghn control protocol; Comprise Signal Separation conversion equipment, IPTV service terminal CPU, control power supply and audio frequency and video output mechanism based on the Ghn agreement; Said control power supply links to each other with the audio frequency and video output mechanism with Signal Separation conversion equipment, IPTV service terminal CPU based on the Ghn agreement, and said audio frequency and video output mechanism input links to each other with IPTV service terminal CPU output, and said IPTV service terminal CPU input links to each other with Signal Separation conversion equipment output based on the Ghn agreement; Said Signal Separation conversion equipment based on the Ghn agreement is connected with incoming line; Said Signal Separation conversion equipment based on the Ghn agreement comprises and separates that conversion equipment main body, AFE are amplified chip and based on the PHY&MAC conversion of signals chip of Ghn agreement, and said AFE amplifies chip and is arranged at PHY&MAC conversion of signals chip based on the Ghn agreement and separates in the conversion equipment main body, and said incoming line links to each other with AFE amplification chip one end; Said AFE amplifies the chip other end and links to each other with PHY&MAC conversion of signals chip one end based on the Ghn agreement, and the said PHY&MAC conversion of signals chip other end based on the Ghn agreement links to each other with IPTV service terminal CPU input.

Improve as the another kind of the utility model, said incoming line is telephone wire or cable or power line, and this patent is owing to adopt the Signal Separation conversion equipment based on the Ghn agreement, so telephone wire or cable or power line all can be used as incoming line.

There are problems such as signal source is limited, high at the inner integrated various information source modular converter cost of IPTV service terminal, the household internal wiring is complicated, difficult in maintenance in the utility model when having only one or two independent signal source interface to ordinary numbers IPTV service terminal product in the current market; Based on the up-to-date family wired network standard Ghn of ITU-T; Design a kind of novel I PTV service terminal that uses Ghn; Utilize existing home network and this terminal; The user can choose at random transmission medium and be transferred to the Ghn module as information source channel; The Ghn module is done the IPTV service terminal signal in the information source channel according to user's demand and is separated conversion, is transferred to IPTV service terminal CPU then, after the IPTV service terminal CPU signal that transmission comes to Ghn is done decoding processing; The final audio frequency and video that realize are exported; Therefore this patent can be simplified the routing network in the room, reduces unnecessary knob-and-tube wiring, and the user needn't receive the restriction of existing home appliance transmission medium just can enjoy various multimedia services convenient, fast, efficiently.
