Detailed description of the invention
Fig. 1 is the structural block diagram of the utility model.
Specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.It should be noted that not conflicting
In the case where, the feature in following embodiment and embodiment can be combined with each other.
As shown in Figure 1, a kind of KTV plate song-order machine with DVB function, including KTV plate song-order machine master control and KTV
The HDMI OUT interface of plate song-order machine master control connection；DVB master control, the HDMI connecting with DVB master control turn MIPI conversion chip；It adjusts
Humorous frequency-selecting master control, the TUNER IN interface, the first signal output/input interface and the second signal that connect with tuning frequency-selecting master control are defeated
Out/input interface, the TUNER IN interface are connected with RF radiofrequency signal, and the tuning frequency-selecting master control passes through first signal
Output/input interface is connected with the first modem, first modem also with the KTV plate song-order machine master control
Connection, the tuning frequency-selecting master control are connect by second signal output/input interface with DVB master control, and the HDMI turns MIPI and turns
Chip is changed also to connect with the KTV plate song-order machine master control.
Based on above structure, KTV plate song-order machine increases DVB function newly and can be realized by two ways:
The first implementation: RF radiofrequency signal is inputted by the port TUNER IN of tuning frequency-selecting master control (TUNER IC),
RF radiofrequency signal is changed into baseband signal by TUNER IC, then the second demodulator (Demod) built in DVB master control (DVB CPU)
Demodulation, obtains the data flow (TS stream) on logic channel, finally multiple by the solution time-division of solution/Multiplexing module (DEMUX) in DVB
With, digital television business information table and program audio, video data are taken, audio, video data is sent into decoder and is decoded, decoding
Data afterwards via HDMI turn MIPI conversion conversion IC be transferred to KTV plate song-order machine master control, finally by with KTV plate point
The digital audio-video interface HDMI OUT output TV programme that owner controls connection are sung, process of this transmission needs HDMI to turn
The conversion IC of MIPI is by audio-video signal by MIPI protocol conversion at the port MIPI RX energy received signal, last KTV plate
Song-order machine master cpu exports decoded audio-video signal by HDMI OUT.
Second of implementation: RF radiofrequency signal is inputted by the port TUNER IN of tuning frequency-selecting master control (TUNER IC),
RF radiofrequency signal is changed into baseband signal by TUNER IC, then is demodulated to obtain TS stream, the first TS stream input by the first modem
It to plate song-order machine master cpu, is time-multiplexed using the solution of DEMUX, takes digital television business information table and program audio view
Frequency evidence finally exports TV programme by the digital audio-video interface HDMI OUT connecting with KTV plate song-order machine.
By above two mode, it is exportable the received RF radiofrequency signal of DVB can be converted to KTV plate song-order machine
Audio-video signal output.
