Still optionally further, OTT playback terminals could pass through local firstly the need of the waiting information for obtaining programme televised live The program playing plan of outside DVB playback terminals is presented to user for OTT playback terminals：By the EPG of DVB programme televised lives front end (program guide) broadcasts server by the waiting information output of programme televised live and carries out package according to the form of network bag, by with Too net is transmitted, and during transmission, OTT playback terminals can be monitored by ethernet channel, receive this network bag, The network bag that will be got is packaged, parsed, and finally gives the waiting information of programme televised live, and these information include program frequently Road title, program generic, programming events play beginning and ending time etc..
Still optionally further, OTT playback terminals can be according to the programme televised live local played column of waiting information editing for getting Table：The data content of programme televised live waiting information is transferred, program channel title, the program of outside DVB playback terminals is therefrom obtained Generic, programming events play the information such as beginning and ending time, are compiled as local playlist, and these information are played eventually in OTT Presented to user in the form of picture on end, and a Property Name is increased to each program channel, such as belonged to local Program, or belong to the outside program such as programme televised live, it is the program or OTT playback terminals of DVB playback terminals for differentiation Program, facilitates user to select to play.Implementing can in the lump referring to the drawings 9：When user selects the second frequency in the rendition list column During road, OTT playback terminals carry out the programming events waiting information in this channel one week by a form for list to user Represent, user can by hand-held remote control moving focal point, and the programming events that select one of them and will broadcast preengage or Selection is played, such as in schematic diagram No. three program.
Still optionally further, in order to support user can directly use OTT playback terminals remote control equipment select reservation or Directly switch programme televised live, the embodiment of the present invention can realize the operation content control DVB according to user on OTT playback terminals Playback terminal, so that DVB playback terminals switch programme televised live, the audio, video data of the programme televised live that user is specified is transferred to OTT playback terminals：Set up for controlling the simulation of DVB playback terminals to control mapping table；Obtain corresponding to the distant of OTT playback terminals At least one control signal for controlling DVB playback terminals of control equipment；The control signal that will be got recorded simulation control Mapping table processed.
In specific implementation, one can be presented by human-computer interaction interface in OTT playback terminals first and commonly used including remote control The button image layout of function button (volume add-substract key, program switch key, Menu key, mute key, treat switch etc.), on image Button Name ＆ Location is consistent with the OTT remote control equipment material objects of OTT playback terminal actual dispositions；Focus is controlled by timer again Pattern be spaced at regular intervals button image layout in from top to bottom, travel through each key icon successively from left to right, often During one new key icon of secondary arrival, the button value of the OTT remote control equipments corresponding to current key icon is recorded, and point out The function button on the relevant position on DVB remote control equipments that user's operation DVB playing terminal equipments are configured；When user clicks on After corresponding function button (such as volume plus key) on DVB remote control equipments, OTT playback terminals provided by driving interface from Its key assignments buffer zone captures the physics key assignments that DVB remote control equipments are emitted, and physics key assignments is saved in into storage region, Wherein, the physics key assignments mentioned by the embodiment of the present invention is the control signal for controlling DVB playback terminals, the control signal Can be general infrared signal, can also be other wireless signals.When the OTT playback terminals as local terminal are detected When user controls DVB playback terminals by OTT remote control equipments, corresponding control can be transferred by the mapping table of storage region Signal, you can realize the corresponding operating control to the DVB playback terminals as exterior terminal.
Still optionally further, the reservation information of the programme televised live of user is read, and sends control signal and give DVB playback terminals Afterwards, whether can also further confirm that now DVB playback terminals are switched to is programme televised live that user wants viewing, checking Method can be realized by the significant image of program：Gather live by the audio, video data of DVB playback terminal pre-transmission The program identification of program；Correlating programs are identified and local playlist.OTT playback terminals can be from the sound of DVB playback terminals transmission An optional frame image data is used as sample image in video data, then gathered out from sample image and can represent programme televised live Program identification, such as station symbol, then station symbol is associated with local playlist, corresponding to corresponding live in local playlist Program.The program identification of collection can be a kind of prefabricated station symbol, and it can be used for checking DVB playback terminals is according to control signal The no programme televised live for being switched to user's reservation, fails to be switched to when verifying after DVB playback terminals cut platform according to control signal During the programme televised live of user's reservation, need to continue to send control signal, until DVB playback terminals are switched to the live section of user's reservation Untill mesh.
In specific implementation, the method for gathering program identification is specifically as follows：From the live section that DVB playback terminals are transmitted Sample image is extracted in purpose audio, video data, and sample image is saved in storage device into (storage with document form Equipment can be USB storage or mobile hard disk etc.), storage device is then accessed by computer, obtained from storage device Get sample image；Or sample image is pushed directly to by object-computer by network channel by OTT playback terminals.In meter On calculation machine, sample image is opened by image analysis tool is analyzed, according to program station symbol pattern display form, from sample image Middle extraction can represent the crucial point coordinates of the program identification (can reflect program station symbol pattern) of program and record Come, and R, G, B value of these crucial point coordinates are obtained by image analysis tool.Thus the sample graph of each program has just been obtained As included in the set of program identification Grid Track and along path each coordinate points rgb value.Wherein, collection In the station symbol of program identification, i.e. programme televised live, the prefabricated storage region to as the OTT playback terminals of local terminal, and support Server end is updated by network channel, added or deleted.
In specific implementation, when using station symbol as the standard of comparison, it is thus necessary to determine that the spatial dimension of case of marking on a map is put into effect, by this model Interior image is enclosed as analysis and identification object, such that it is able to improve the recognition efficiency and accuracy of station symbol pattern.Determine station symbol The method of the spatial dimension of pattern is to read the coordinate information of known each program station symbol, by comparing the starting of each station symbol Method with coordinate value size is terminated, the maximum region scope where obtaining station symbol pattern, and by the coordinate value of this regional extent Record, using the image in this regional extent as analysis, identification object.Because the station symbol pattern of each program is built-in Presented in program video image, the sample image that we obtain be also station symbol pattern and video pictures are overlapped it is mixed Result after conjunction.By observation, it is understood that the color of station symbol pattern, form and position are changeless, and video figure Seem to do dynamic change over time, can thus cause that sample image is appeared on the stage video image of the case under sometime of marking on a map What is showed under the influence of background is not clear enough, it is difficult to recognize.Such as, when in the regional extent where station symbol pattern, at certain Carve, video image color and the station symbol color of the output of DVB playback terminals relatively when, the morphological feature of station symbol pattern will not Substantially, the sample image for obtaining in this case is difficult to gather station symbol.
For this kind of situation, in this element, present invention introduces the gray scale processing method in image domains, gray value refers to black The color depth of pixel in white image, typically from 0 to 255, white is 255 to scope, and black is 0, therefore black and white picture is also referred to as ash Degree image, after each point R, G, B values are converted into gray value in image, is more convenient the extraction of characteristic pattern in image.Based on above-mentioned Knowledge, the specific implementation method in the present invention is to select in multiple sample images of not sampled to same program channel in the same time, The grey level of image is asked for according to averaging method to each point pixel in the range of station symbol region in every sample image, such as The color of certain point is RGB (R, G, B) in regional extent, then, we can be converted into gray scale by mean value method Gray, i.e.,：, then with Gray be replaced for the original RGB of pixel (R, G, B) unification by Gray=(R+G+B)/3, is formed New color RGB (Gray, Gray, Gray), all of pixel in region is entered using the new color value that the method is obtained The image that row is represented is exactly gray-scale map.Obtained gray-scale map, it is possible to compare gray value in the range of station symbol region from To the variation tendency at center, by statistical comparison, area grayscale value in image border is approached and edge in the range of chosen area at edge Region is with the obvious image of central area grey value difference as sample image.For example：Known each program platform is read first Target coordinate information, the method by comparing the starting of each station symbol and terminate coordinate value size, obtains where station symbol pattern most Big regional extent, upper left corner area Range Representation is：Laterally [XLmin~XLmax], longitudinal direction [YLmin~YLmax], the upper right corner Regional extent is expressed as：Laterally [XRmin~XRmax], longitudinal direction [YRmin~YRmax], and the coordinate value of this regional extent is protected Leave and；HDMI input driving interfaces are recalled, the audio, video data that is currently played of DVB playback terminals is obtained, and according to The package feature (the beginning sign part of video data) of video data therefrom extracts a frame video image data, and storage is arrived In video image buffer zone；Read the station symbol pattern region scope of foregoing storage, [XLmin~XLmax], [YLmin~ YLmax], [XRmin, XRmax], [YRmin, YRmax], along this regional extent, each picture is extracted from vedio data Vegetarian refreshments information, and be saved into station symbol buffer zone；Gray value is asked for pixel each point in station symbol, the gray scale of station symbol is obtained Figure, and judge whether the gray-value variation trend of each pixel gray-scale map Nei meets condition：Fringe region gray value is close, side Edge region is obvious with central area grey value difference；When meeting, close fringe region gray value, fringe region and central area are grey Angle value difference substantially the two conditions when, confirm station symbol gather successfully.
In specific implementation, a program names can be uniquely determined because the station symbol of program has the station symbol of uniqueness, i.e., Claim, and the position of station symbol is relatively fixed, be usually located at the upper left corner or the upper right corner of video screen, thus can using station symbol as Standard, after confirming that DVB playback terminals cut platform according to control signal, if be switched to the programme televised live of user's reservation：DVB is played After terminal cuts platform according to control signal, the audio, video data for transmitting programme televised live gives OTT playback terminals, by HDMI, OTT After playback terminal receives the audio, video data of programme televised live, an optional frame video image is used as to be verified from audio, video data Image；The program identification of preset programme televised live is obtained, whether comparison image to be verified is consistent with program identification, if comparing out Image to be verified is consistent with program identification, it is determined that DVB playback terminals have been switched to the programme televised live of user's reservation；Or Person, if comparing out, image to be verified is inconsistent with program identification, continuation sends control signal and gives DVB playback terminals, broadcasts DVB The operation that terminal performs switching programme televised live according to control signal is put, until image to be verified is with the comparison result of program identification Unanimously.
In implementing, the program identification of preset programme televised live is obtained first, wherein, program identification can be adopted for foregoing The station symbol of collection, whether comparison image to be verified is consistent with program identification can be embodied in accordance with the following methods：Obtain program platform The included Grid Track set of mark, wherein, coordinate is indicated in units of pixel, and each coordinate points its pixel R, G, B value, each pixel take three bytes in internal memory, and R, G, B respectively account for a byte；Secondly, along in station symbol information Grid Track, R, G, B value that each corresponding with Grid Track is put are taken out from image to be verified successively, by this R, G, B Value is compared with R, G, B value of the same coordinate point of station symbol, calculates R, G, B difference of each pixel on track, and Further, calculate on image to be verified along its each pixel of station symbol track R, G, B formed difference constitute it is equal Value, its computational methods are, divided by pixel total number after carrying out adding up respectively by R, G, B difference of each point, to draw error mean, And the difference according to the pixel for obtaining is compared with error mean, judge whether it (takes here in error allowed band ± the 5% of the average that each vegetarian refreshments R, G, B difference is constituted is used as error range)；If the difference for calculating, can in error range Think R, G, B Distribution value trend of pixel in image to be verified and the R of each pixel in known reference image station symbol track, G, B value trend is identical, thinks that current DVB playback terminals have been switched to the programme televised live of user's reservation accordingly；If the difference for calculating Value is not in error range, then it is assumed that DVB playback terminals do not switch to the programme televised live of user's reservation currently, it is necessary to continue to send Control signal gives DVB playback terminals, makes DVB playback terminals that the operation of switching programme televised live is performed according to control signal, until treating Authentication image is consistent with the comparison result of program identification.
Still optionally further, OTT playback terminals support that user can be with by the method that OTT playback terminals preengage programme televised live Including：Receive user and be based on the reservation information that programme televised live is played in the selection reservation of local playlist, reservation information includes live The broadcasting initial time of program.So, after DVB playback terminals have been switched to the programme televised live of user's reservation, OTT is played eventually Hold monitor in real time reproduction time, it is ensured that user is watched the programme televised live of reservation on time：First, set based on broadcasting initial time Time threshold is put, time threshold is the switching for being switched to output programme televised live audio, video data that OTT playback terminals are set Time point, such as reservation play first 10 seconds of programme televised live time started；During arrival time threshold value, OTT playback terminals are being checked Whether the program of broadcasting is programme televised live, if programme televised live is currently played, need not be switched, if being currently played , it is necessary to switch broadcasting content during the program of OTT playback terminals, the audio frequency and video number of the programme televised live that transmission DVB playback terminals send According to display device, display device is set to play the audio, video data of the programme televised live of user's reservation.
In the embodiment of the present invention, at least one HDMI input interfaces are configured with as the OTT playback terminals of local terminal, can Using HDMI input interfaces as other exterior terminals, such as DVB playback terminals are accessed OTT playback terminals, are passed through in a program HDMI is called to be input into driving interface, very accurate, convenient can get DVB playing terminal equipments in OTT playback terminals passes through The audio, video data content that HDMI is transmitted.It is real because HDMI input interfaces are OTT playback terminals from the interface for setting When applying the embodiment of the present invention, without changing DVB playback terminals again, therefore the cost of implementation of the embodiment of the present invention is relatively low.
