Abstract
The invention relates to a radio time shifting signal processing method for an on-vehicle entertainment messenger system. The method comprises the following steps of: 1) detecting a flameout/ignition state and a power state to judge whether a vehicle is powered on or not by using a vehicle interface processing board, and executing a step 2) if the vehicle is powered on; 2) after a modem receives a radio signal, converting the radio signal into a digital signal by using a signal processor; 3) transmitting the digital signal to an application processing board; 4) storing the digital signal into a circulating storage file by using the application processing board; 5) compressing the circulating storage file and storing the compressed circulating storage file in a hard disk; 6) pressing a pause button down to start a radio time shifting processing module, and decompressing and reading the digital signal at any position along with operations on a human-computer interface by using a radio digital signal read pointer; and 7) transmitting the read digital signal to the signal processor, and converting the digital signal into an analogue signal and outputting the analogue signal by using the signal processor. Compared with the prior art, the method has the advantages of enabling a user to move back to a position from which the user wants to start listening at any time, and the like.

Technical field
The present invention relates to a kind of time-shifting signal processing method, especially relate to the time-shifting signal processing method and the device of broadcasting in a kind of car entertainment communication system.
Background technology
The vehicle-mounted driver of being broadcast to provides the more information source, provides colourful amusement to enjoy also for simultaneously the uninteresting driving work of driver, and the broadcasting in the car entertainment communication system is a kind of basic and important equipment of automobile.But the broadcasting in the existing car entertainment communication system has the following disadvantages:
1) as user during at broadcast listening, if when in the broadcasting user's interest telephone number of broadcast or station address being arranged, wish hard of hearingly as the user, can't suspend the back rollback, interested content hard of hearing.
2) as user during at broadcast listening, stop as needs and to refuel, by suspending, after returning car, can then listen to, but can't fast forwarding and fast rewinding have been delayed but the program wanting to hear to any user by continuing key.
Summary of the invention
Purpose of the present invention is exactly that the time-shifting signal processing method and the device of broadcasting in a kind of car entertainment communication system that can allow the user return back at any time oneself to want the position of listening to be listened to is provided in order to overcome the defective that above-mentioned prior art exists.
Purpose of the present invention can be achieved through the following technical solutions:
The time-shifting signal processing method of broadcasting in a kind of car entertainment communication system is characterized in that, may further comprise the steps:
1) the vehicle interface disposable plates judges by detecting flame-out fired state and power supply status whether vehicle has electricity, if yes, and execution in step 2);
2) be translated into digital signal by signal processor behind the modulator-demodulator receiving broadcast signal;
3) digital signal is imported the application disposable plates into via bus;
4) use disposable plates and deposit digital signal in a circulation storage file;
5) after being compressed, the circulation storage file is placed in the hard disk;
6) pause button is pressed and starts the time-shifting processing module of broadcasting, and the read pointer of broadcast figure signal can and read digital signal along with any local decompress(ion) of operating in of man-machine interface;
7) digital signal that reads is via bus input signal processor, and signal processor is exported after being translated into analog signal.
Judge in the described step 1) whether vehicle has electricity as follows:
11) when car igniting and power supply have electricity, for vehicle has electricity condition;
12) when car igniting and power supply do not have electricity, for vehicle has electricity condition;
When 13) flame-out and power supply has electricity when car, for vehicle has electricity condition;
When 14) flame-out and power supply does not have electricity when car, be the vehicle electroless state.
The time-shifting signal processing apparatus of broadcasting in a kind of car entertainment communication system, it is characterized in that, comprise and use disposable plates, vehicle interface disposable plates, hard disk, man-machine interface, modulator-demodulator, signal processor, described application disposable plates links to each other with the vehicle interface disposable plates, described man-machine interface is connected respectively at using disposable plates with hard disk, described modulator-demodulator links to each other with signal processor, and described signal processor links to each other respectively with the vehicle interface disposable plates with the application disposable plates.
Described application disposable plates comprises audio management module, time-shifting processing module, compression/decompression module.
Compared with prior art, the present invention has the following advantages:
1, in office and can suspend when listening to the radio programme, return back to and want the place of listening.
When 2, vehicle is flame-out, the content of broadcasting can be preserved, broadcast listening can be continued in the time of in the user gets back to car.
When 3, stopping working running background, when exhausting soon, can withdraw from automatically as electric quantity of power supply.
4, use the Compress softwares algorithm, reduce broadcast figure signal storage capacity.

Fig. 2 is a structural representation of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Figure 1 and Figure 2, the time-shifting signal processing method of broadcasting in a kind of car entertainment communication system may further comprise the steps:
1) the vehicle interface disposable plates judges by detecting flame-out fired state and power supply status whether vehicle has electricity, if yes, and execution in step 2);
2) be translated into digital signal by signal processor 2 behind modulator-demodulator 1 receiving broadcast signal;
3) digital signal is imported into via bus and is used disposable plates 4;
4) use processing 4 plates and deposit digital signal in a circulation storage file;
5) after being compressed, the circulation storage file is placed in the hard disk 6;
6) pause button is pressed and starts the time-shifting processing module of broadcasting, and the read pointer of broadcast figure signal can and read digital signal along with any local decompress(ion) of operating in of man-machine interface 5;
7) digital signal that reads is via bus input signal processor 2, and signal processor 2 is exported after being translated into analog signal.
The time-shifting signal processing apparatus of broadcasting in a kind of car entertainment communication system, comprise and use disposable plates 4, vehicle interface disposable plates 3, hard disk 6, man-machine interface 5, modulator-demodulator 1, signal processor 2, described application disposable plates 4 links to each other with vehicle interface disposable plates 3, described man-machine interface 5 is connected respectively at using disposable plates 4 with hard disk 6, described modulator-demodulator 1 links to each other with signal processor 2, and described signal processor 2 links to each other respectively with vehicle interface disposable plates 3 with application disposable plates 4.Described application disposable plates 4 comprises audio management module 41, time-shifting processing module 42, compression/decompression module 43.
