Based on above-mentioned mobile terminal hardware configuration and communication system, each embodiment of the inventive method is proposed.
As shown in Figure 3, first embodiment of the invention proposes a kind of program automatic obtaining method, comprising:
Step 301, program broadcasting apparatus and a mobile terminal set up wireless connections.
Because current program broadcasting apparatus (as intelligent television) and mobile terminal have Bluetooth function mostly, thus in the present embodiment, program broadcasting apparatus and mobile terminal can adopt bluetooth connected mode, program broadcasting apparatus as main side, mobile terminal as from end, all need to open Bluetooth function initial time both sides, main side is carried out active and is searched in program playing process, initiate pairing, and from after hold link setup successfully, program broadcasting apparatus and mobile terminal both sides get final product transceiving data.
Concrete pairing method of attachment is: main side makes a call, first find out around be in can by search from end; Main side is found after end, matches with from end, now may need to input the PIN code from end, also may not need to input the PIN code from end, determine according to the bluetooth configuration information from end.
Certainly, the radio connection of program broadcasting apparatus and mobile terminal is not limited to bluetooth approach, also can adopt widely used WIFI connected mode etc., more can adopt traditional wired connection mode, communicates as long as can realize both.
Step 302, in program playing process, whether real-time detection beholder leaves program viewing area, when detecting beholder and leaving program viewing area, performs step 303.
In this step, detector can be installed near program broadcasting apparatus, be detected the state of beholder by detector.
Particularly, detector can be microwave detector, utilizes field interference principle or beam break formula principle to realize detection, is made up of microwave transmitter, transmitting antenna, microwave receiver, reception antenna.Microwave transmitter goes out the good modulated microwave bundle of directionality by transmission antennas transmit, and operating frequency is selected usually at 9 to 11GHz, and reception antenna and transmitting antenna need staggered relatively, to receive the modulated microwave bundle of transmission antennas transmit.
In actual applications, microwave transmitter, transmitting antenna can be laid on the housing of program broadcasting apparatus, microwave receiver, reception antenna are laid in the rear, beholder position on program broadcasting apparatus opposite, as the sofa seat back of frequent institute position when beholder watches TV.
When having obstacle or the detection of a target between reception antenna and transmitting antenna, owing to destroying the normal propagation of microwave, the microwave signal that reception antenna is received weakens to some extent; When not having obstacle or the detection of a target between reception antenna and transmitting antenna, the microwave signal normal propagation of transmission antennas transmit, reception antenna will receive stronger microwave signal.Thus, detector the power of microwave signal received by reception antenna can judge the state of the detection of a target: when the microwave signal received is more weak, judge that the detection of a target is in search coverage; When the microwave signal received is stronger, judge that the detection of a target leaves search coverage.
In the present embodiment, the search coverage of detector is optionally set as roughly the same with the program viewing area of program broadcasting apparatus, can improve the accuracy of result of detection like this.Certainly, detector is not limited to adopt said structure, other also can be adopted to form arbitrarily, as long as can realize identical detection object.
Step 303, for the current TV programme play, be extracted in beholder and leave programme information in the time period of program viewing area, whether real-time detection simultaneously beholder return in program viewing area, if return, then perform step 304, otherwise continue to perform this step.
In this step, the kind of the programme information extracted includes but not limited to: screen shot, audio file, video file; Extracting mode includes but not limited to: according to predeterminated frequency extraction interval time, extract etc. according to program pictures content type.
Due to program pictures in addition to images, also may there be captions and/or sound, and captions and sound have very important effect for quick and precisely passing on of information, thus, the present embodiment is extracted in the method that beholder leaves the programme information in the time period of program viewing area and can be specially: if actual program picture has captions voiceless sound, then sectional drawing is carried out to actual program picture, store according to the order of sequence according to after default naming rule name; If actual program picture has sound without captions, then recording audio file stores; If actual program picture has sound for there being captions, then sectional drawing is carried out to actual program picture and store according to the order of sequence, simultaneously recording audio file corresponding stored.This implementation method, obtains comparatively complete caption information and audio-frequency information as much as possible, browses to facilitate user the main program content looked back in its time departure section rapidly.
For extracted screen shot, audio file, can name according to extraction time (as: during the XX month XX day XX XX divide XX second+title of TV programme), make it possible to sequential storage, facilitate subsequent treatment to show beholder; The screen shot that correspondence is extracted simultaneously and audio file, must adopt corresponding naming rule, to facilitate the matching treatment of follow-up both realizations.
In addition, detect in this step in the Methods and steps 302 whether beholder return in program viewing area and detect beholder whether to leave the method for program viewing area identical, analyze judgement by the microwave signal Strength Changes received by the reception antenna to detector equally, repeat no more herein.
Step 304, when detecting beholder and returning in program viewing area, stop operating the extraction of current program information, the programme information extracted directly is sent to mobile terminal, or send to mobile terminal after treatment in beholder's time departure section.
In this step, for promoting the experience of user, needed to carry out preliminary treatment to this programme information before programme information is sent to mobile terminal: according to priority sequence of extraction, the matching relationship of screen shot/audio file, loading is carried out to the screen shot extracted and/or audio file and is made into lantern slide.Like this, beholder directly clicks to play and can browse the programme content outline looked back in its time departure section after mobile terminal receives information.
To sum up, when beholder returns after of short duration leaving, also can fast, the main program content be well understood in its time departure section, greatly improve the experience of user.
Embodiment two
In embodiment one, program automatic obtaining method is based on separate program broadcasting apparatus and a mobile terminal, wherein, program broadcasting apparatus has program playing function (as intelligent television), and mobile terminal also has portability while having various application function (as audio and video playing function, picture look facility, memory function), embodiment one realizes program automatic acquisition by means of both features just, namely the programme information needed for program broadcasting apparatus extracts, be sent to mobile terminal to store, user carries out browsing checking on mobile terminals.
And in the present embodiment two, program broadcasting apparatus also can be specially a mobile terminal in fact, now program broadcasting apparatus itself has program playing function, audio and video playing function, picture look facility, memory function simultaneously.Thus in the present embodiment two, in the method flow realizing program automatic acquisition, programme information without the need to sending programme information to other mobile terminals again, can be stored in local terminal by program broadcasting apparatus after the programme information needed for extracting, and to be browsed at any time check by user afterwards; The concrete extracting method of programme information and preprocess method identical with embodiment one, repeat no more herein.
Embodiment three
