Refer to Fig. 2, a kind of flow chart of the advertisement broadcast method of starting shooting in the embodiment of the present invention.The present embodiment is to the further illustrating of embodiment mono-, in detail handling process step as described below:
201, Set Top Box receives start-up command, according to start-up command, opens CPU;
Wherein, Set Top Box is a kind of conversion equipment that digital audio-video signal is converted to analog signal, it is to the reduction of decode through the image of digitalization compressed and voice signal, and video and voice signal that generation is simulated, provide high-quality TV programme by display device.Set Top Box is mainly comprised of CPU, codec and nonvolatile memory (internal memory), and wherein CPU can be called the heart of Set Top Box.After CPU control codec completes digital signal decoding, what obtain is audio and video data streams, because display device cannot be to this audio frequency and video number stream according to playing, therefore first to carry out demultiplexing to audio, video data, audio and video data streams is divided into video data and voice data, CPU carries out filtering processing by video data and voice data subsequently, remove unnecessary interference signal and obtain more satisfactory quality signal, to obtain again quality signal and deposit in internal memory, as the input data of display device.
Therefore, in Set Top Box, receive after start-up command, first will make power module supply electric-opening CPU to CPU according to start-up command, CPU can automatically perform initialization setting after opening, then with the time of part second, carry out self-test, with assurance system, move in normal condition.
202,, in time threshold, judge between Set Top Box and display device and whether set up and communicate by letter, if go to step 203; Go to step 204 if not;
Above mention the high-quality sound, vision signal of Set Top Box output as the input data of display device.This signal is to carry out transfer of data by the audio and video output interface of Set Top Box and display device.Common audio and video output interface has: composite video broadcast singal (CVBS) interface of only supporting SD, a left side for simulation, right audio channel interface, audio frequency (S/PDIF) interface of numeral, support S terminal video (S-Video) interface of bright signal separation, support component vide (YPbPr or the YCbCr) interface of brightness and color difference components signal, support Video Graphics Array (VGA) interface of color mode (RGB) signal, support high-definition multimedia (HDMI) interface, component vide (D4) interface of the SCART standard pronunciation video interface in Europe and Japan etc.Whether whether CPU can have transfer of data to judge between Set Top Box and display device to set up and communicate by letter by monitoring above-mentioned audio and video output interface, thereby indirect proof display device has been opened and started transfer of data with this Set Top Box, then just can enter step 203.In preferred embodiment, consider that current HDMI interface is the main interface of audio, video data transmission between Set Top Box and display device, so the present invention is example by the communication of monitoring HDMI interface, be further described.
Please refer to Fig. 3, the pinouts of HDMI interface and digital visual interface (Digital Visual Interface, DVI).Wherein, the interface pin figure that the left side is HDMI, the interface pin figure that the right is DVI, the function of HDMI/DVI is that hot plug detects (HPD).HPD is sent to a monitor signal of set-top box CPU from display device output, whether this signal sets up the foundation of communicating by letter as the CPU monitoring HDMI/DVI display device of Set Top Box with Set Top Box.
The effect that hot plug detects is when display device is connected with Set Top Box by DVI interface or disconnects, and the CPU of Set Top Box just can monitor by the HPD pin (19 pins in Fig. 3) of HDMI/DVI this event and occur, and makes corresponding response.When the CPU of the Set Top Box HPD pin by HDMI interface monitors display device and is connected with Set Top Box, CPU can transmitted signal request Set Top Box establish a communications link by this HDMI interface and display device.In like manner, when the CPU of the Set Top Box HPD pin by HDMI interface monitors display device and Set Top Box and disconnects, CPU can transmitted signal request Set Top Box disconnect by this HDMI interface and display device.When the voltage that conventionally CPU monitors HDMI/DVI interface HPD pin is greater than 2V, is judged as display device and is connected with Set Top Box, when monitoring the voltage of HPD pin and be less than 0.8V, be judged as display device and be connected and disconnect with Set Top Box.
It should be noted that, CPU is the read-only digital signal of getting conventionally, but it is an analog signal that HPD is drawn high what produce after current potential, can not be read by CPU, therefore, before CPU reads HPD signal, this HPD signal also will be through a step analog-digital conversion process, analog signal is converted to corresponding digital signal (as high potential correspondence 1, electronegative potential correspondence 0),, when CPU receives digital signal " 1 ", determine that Set Top Box is connected with display device.Therefore the CPU of Set Top Box can easily monitor the connection status of this Set Top Box and display device, thereby just can judge the input pattern whether display device has been opened and has selected HDMI.Because after only having display device to open, the start advertisement of broadcasting could viewed arriving.
If but gone wrong in observation process, for example the pin of HPD damages or the display device that the other reasons of display device causes is connected with Set Top Box, when but the CPU of Set Top Box does not monitor HPD signal, if Set Top Box is not play start always, advertisement does not just make other modules of Set Top Box normally not open yet, and causes Set Top Box cannot enter the main interface of normal system and can not normally be used.In order to solve above-mentioned fortuitous event, the present invention has also added a time threshold in step 202, this time threshold arranged according to the time of the average start of Set Top Box, because the current set-top-box opening time average of Android system is about 20 seconds, if in transmitter top box start-up command after 20 seconds, also do not monitor HPD signal, Set Top Box just cannot enter the main interface of normal system, also just cannot carry out subsequent operation, therefore time threshold is made as and is more than or equal to 20 seconds, when surpassing this time threshold, also do not monitor HPD signal, just can think that monitored end breaks down, can skip subsequently broadcasting start advertisement and continue start process.That is to say, if the CPU of Set Top Box does not monitor HPD signal in default time threshold, think and occur fortuitous event.In order to guarantee under fortuitous event, Set Top Box can also normally start, and now, by skips steps 203, carry out step 204.
203, play start advertisement;
According to above-mentioned monitoring method, after the CPU of Set Top Box monitors Set Top Box and display device and establishes a communications link, prove that this display device has had the condition of broadcasting start advertisement, so CPU will transfer the address of the start advertisement prestoring from the internal memory of Set Top Box, by HDMI interface, send to display device, make display device according to this address, from the internal memory of Set Top Box, obtain the audio and video data streams of start advertisement, the broadcasting of the advertisement of then starting shooting.
204, enter the main interface of system.
In the ordinary course of things, after start advertisement finishes playing, CPU will controller top box power module give that other operational modules (as data broadcast, system upgrade, network connection etc.) power on, initialization, then on display device, just can present a main interface of complete system, be just all processes of set-top-box opening.
If but there is above-mentioned accident, just can skip and play start advertisement, proceed start, the main interface of the system that enters.Arranging like this can guarantee that the system of Set Top Box opens smoothly after monitoring unsuccessfully, improved the reliability of system.
As can be seen here, the present invention, by whether setting up communication between monitoring display device and Set Top Box, determines the opportunity of playing start advertisement; If set up communication confirm current display device selector top box be input equipment, and then start to play start advertisement, in the time of therefore just can guaranteeing to start shooting, user can watch start advertisement.
