Built-in central processing unit S-MCU of described music integration module and interface circuit.
Described self-defining serial or parallel port is the I/O port of TV-MCU and an I/O port of the integrated module interface circuit of music.
The input of described music integration module, output signal are inserted by switching and are connected.
The utility model compared with prior art has many advantages and good effect:
1, the utility model is by installing the music integration module additional on television set.Make that the performance of television set aspect audiovisual obtains expanding, contain melody and its built-in S-MCU program of curing in the music integration module.TV central processing unit TV-MCU sends various control commands by iic bus or self-defining serial or parallel port to the music integration module, switch, selected songs, volume, the speed of control music integration module.The music integration module can keep its original operating state always before receiving new instruction, just change its operating state when the new instruction of receiving that TV central processing unit TV-MCU sends.Like this, can think music appreciating at any time, and can select song easily, improve practicality, the interest, recreational of television set in the gap of seeing TV programme.
2, simple in structure, easy to make, be convenient to implement and promote.
Description of drawings
But Fig. 1 is music integration module and the control circuit figure of an embodiment of television set of the utility model independently playing music.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Referring to Fig. 1, but a kind of television set of independently playing music mainly is made up of decoder 2, audio frequency power amplifier 4, the loud speaker 5 of TV central processing unit TV-MCU1, exportable AV or TV audio signal.Described TV central processing unit TV-MCU 1 is connected with the I/O port P2-0 of a music integration module 6 by self-defining serial communication port I/O-2.The audio output port V01 of music integration module 6 is connected to an input A of an electronic switch 3, the AV audio signal of decoding signals output 2 and TV audio signal are connected respectively to two input B, C in addition of electronic switch 34, the output of electronic switch 3 is connected with the input of audio amplifier circuit 4, the output of audio amplifier circuit 4 connects loud speaker 5, and the control end of electronic switch 3 is connected to the control signal delivery outlet I/O-1 of TV-MCU.Music integration module 6 built-in central processing unit S-MCU and interface circuits.The input of music integration module, output signal comprise that audio output signal V01, serial communication signal I/O-2, power vd D and GND insert 7 by switching and be connected.
Described self-defining serial communication port present embodiment is the I/O end I/O-2 of TV-MCU and an I/O port P2.0 of music integration module 6 interface circuits, and the communication protocol of employing is as follows:
The control impuls transmission specification of music integration module 6 is set at:
Logic level " 0 "
Logic level " 1 "
The control command data transmission is a unit with byte (8).
The effective control command data beginning that sends has start bit, finishes to add check digit.
The start bit impulse waveform:
Minimum interval (greater than 10ms) is arranged between per two subcommands.
For example: it is as follows to send order (10100101B) waveform:
Check digit adopts even parity check, and when promptly the number of " 1 " in the 8 order of the bit data was even number, check digit was " 0 ", and check digit is " 1 " during for odd number.
Command code is divided into two parts, and preceding 4 is the command functions symbol, and back 4 is to quantize symbol, is defined as follows table:
