Description
Technical field
The present invention relates to a kind of processing television signals technology; Particularly a kind of television set and remote controller that loads the method for television channel identifying information and utilize this information; So that television set can obtain and utilize this television channel identifying information to preset television channel, and be convenient to TV watching person and utilize corresponding remote controller to select interested TV programme easily.
Background technology
After the remote controller invention, using a teleswitch, (also claim: switching TV channel television set) is that the televiewer controls one of the most general mode of television set to the control television receiver.
Using a teleswitch and control the operation of television set switching TV channel, is to be accomplished by the interlock circuit in remote controller and the television set.Its basic principle is: press digital keys or the function button that is provided with on the remote controller as the user; For example: buttons such as "+", "-", " on turn over (▲) ", " turning over
down "; The integrated circuit that is provided with in the remote controller will produce the coding to respective keys accordingly; And with this coded modulation to carrier wave with certain frequency; Via the infrared remote-controlled signal radiating circuit that is provided with on the remote controller, there is the carrier wave of keyboard-coding to send aforementioned modulation.On television set, be provided with corresponding infrared remote-controlled signal receiving circuit.After this infrared remote-controlled signal receiving circuit receives the carrier signal from remote controller, it is carried out demodulation, and therefrom obtain corresponding keyboard-coding.In addition; In television set, also be provided with the circuit that is used for keyboard-coding identification; This circuit is discerned keyboard-coding; Corresponding to which function button or digital keys on the remote controller,, and be transmitted to corresponding functional circuit in the television set with the coding confirming to receive with the order that obtains to carry out.
For example: after television set receives aforementioned " on turn over (▲) " pairing coding of button; After aforementioned circuit identification, know that the control command that remote controller sends is: require television set that the current television channel of playing is switched to last television channel forward to keyboard-coding identification.Related circuit in the television set then can obtain the tuner parameters of last television channel based on this order, and uses this parameter control television set tuner to select the TV signal of last television channel.
Strictly speaking, television channel is a frequency range in the notion of radio broadcasting; It refers in particular to the TV programme of in this frequency range, transmitting.According to the standard of the channel division of Chinese radio and television, the 8MHz bandwidth is used at each wireless channel station, because the centre is inserted with factors such as FM broadcasting, actual incorporating in the radio frequency range of using to TV programme can be arranged 68 television channels.If through wired closed-circuit television system TV transmission program,, can on the basis of 68 television channels, further increase again because there is not other radio traffic.Although the division of the TV broadcast channel of the U.S., Europe, Japan is different with China; Different (for example: the TSC-system TV that the U.S. adopts closes the ripple signal because of standard is different but these differences also only are bandwidth that wireless channel takies; From 2 channel to 69 channels; The bandwidth of each channel is 4MHz), other aspects are consistent basically.For digital television signal,, can transmit hundreds of even thousands of TV programme signals owing to do not receive the influence of radio broadcasting frequency bandwidth.
Existing simulated television be furnished with at least usually a TV tuner (be commonly called as: tuner) and the TV programme preselector (hereinafter to be referred as: preselector).About the technology contents of TV tuner and preselector all has disclosure in the textbook of many television sets and television broadcasting.For example: just at length introduced the ABC of radio and television and the technology of television set in " TV Principles and technology " book that publishing house of He'nan University publishes.
TV tuner is the important devices in the television set, is divided into two kinds of analog television tuner and digital TV tuners.The effect of analog television tuner be to the TV signal that receives amplify, gating, frequency conversion, the demodulation of figure sound, it is transformed into a fixing intermediate frequency output with the high-frequency TV signal of many different frequencies, accomplishes moving of frequency spectrum.When analog television tuner selects the high-frequency TV signal with a certain frequency to be transformed into fixing intermediate frequency output, need a local oscillation signal, this local oscillation signal generally derives from preselector.
The effect of digital TV tuner is that digital television signal is carried out high frequency amplification, comparison process, channel-decoding and demodulation.During digital TV tuner receiving digital broadcast TV signal, not only to accomplish analog tuner the frequency spectrum shift function that will accomplish, separate the mediation channel-decoding but also will accomplish.For digital TV tuner, from digital broadcasting-television signal, select the needed television channel of user, come down to utilize the relevant parameter of digital television program that packet specific in the digital television code stream is separated the mediation channel-decoding.The relevant knowledge of this respect can be consulted " digital television broadcasting principle and application " book that the People's Telecon Publishing House publishes in September, 2007.And the relevant parameter of foregoing digital television program, typically refer to digital television program the bag identifier (Packet Identifier, hereinafter to be referred as: PID), its effect is a program specific in the reference numbers TV code flow.
The task of preselector receive, the parameter of television channel deposits memory in, the parameter of a television channel deposits a memory cell in.Generally speaking, have a plurality of memory cells that are used for store electricity tv channel parameter in the memory of preselector.The memory cell of preselector is many more, and the television channel parameter that can store is just many more, when the quantity of memory cell when being plural, can be these memory cell serial numbers, for example: 0,1,2,3,4.......At present, the preselector of most of television sets has the memory cell more than 100; That is to say: the television channel parameter that present television set can be stored reaches more than 100 mostly.
What store in the preselector of simulated television generally is: the VT parameter of each television channel and various function Control Parameter and memory cell serial number (are also referred to as: channel).Wherein, the VT parameter of television channel is used to offer tuner.What store in the preselector of digital television generally is: the parameter and the channel of the parameter of control figure tuner medium frequency synthesizer, control qpsk demodulator and channel-decoding.
The television channel of television for play switches, and is exactly the parameter that changes television channel on technical spirit; That is to say: the switching of the control television channel that uses a teleswitch; Be actually and utilize remote controller to control control circuit in the television set; From the memory of preselector; Take out the parameter of the television channel that institute will switch to, control TV tuner and select the high-frequency TV signal of a certain frequency is transformed into fixing intermediate frequency output, with the completion frequency spectrum shift.For example: when the user uses a teleswitch after television set sends " 3 ", " 8 " two numerals continuously; Television set is just known after receiving these two numerals: the user will be switched the TV programme of television for play, and the parameter of the target television channel that will switch to be stored in the preselector in the memory cell that is numbered " 38 ".The control circuit of television set can take out the television channel parameter of being preserved from the memory cell of aforementioned being numbered " 38 ", and uses this parameter control TV tuner to select the pairing television channel of this parameter.Like this, television set has just been accomplished the operation based on the channel switching of remote controller.
The fit applications of technology such as remote controller and preselector selects the operation of television channel to bring great convenience to people.People can utilize television set " search platform " function and preselector, and the parameter of the television channel that can search is stored in respectively in the memory cells different in the preselector.For example: utilize producer to be arranged on the TV signal that automatic " searching platform " function in the television set is searched for each TV programme.In case search after the TV programme; The parameter of the television channel that these TV programme are corresponding is just automatically recorded among the memory cell of preselector; So constantly repeat; Up to having searched for all TV programme, and, record in the preselector the parameter of the pairing television channel of these TV programme mode according to table 1.If watch a certain TV programme; Just can import the corresponding memory cell of this TV programme numbering (people with this numbering be commonly called as into: television channel number); The control circuit of television set will be numbered according to this; Corresponding memory cell obtains the parameter of television channel from preselector, chooses the TV signal of corresponding frequencies with the control TV tuner.

Embodiment
The inventor finds under study for action: though people are limited for the memory capability of the corresponding relation of the numbering of things and things itself; But; If use relevantly with things itself, and the character with certain implication or rule remembers, and then the ability of memory will significantly strengthen.Use letter, synthetic information with implication or the pattern of symbols to remember corresponding television channel, then be very easy to memory.For example: as shown in Figure 1; " one in central authorities " this television channel is remembered in first alphabetical letter character of English combination " CCTV1 " with " Chinese Central Television's first programs (hereinafter to be referred as: one in central authorities) ", be more than remembering much easier with " 15 ", " 28 " such numbering.If using the station symbol pattern of one in central authorities as shown in Figure 1 just to remember has been more prone to.
Like Fig. 2,3, shown in 4; Under the prerequisite of using letter character combination 111 or station symbol pattern 112; These letter character combinations 111 or station symbol pattern 112 are shown on the display screen 11 of TV remote controller 10; And be used the operation push-button 12 on the remote controller 10, even need not remember the corresponding relation between the numbering of television channel and preselector memory cell, the control that yet can realize the television set switching TV channel with remote controller 10 like a cork.Certainly, also can the display screen on the remote controller 10 11 directly be configured to touch-screen, can save operation push-button 12 like this, make remote controller 10 miniaturization more, and conveniently use such as special populations such as the elderlys.
But problem is: how to make the numbering of the preselector memory cell in combination of the pairing letter character of many television channels or station symbol pattern and concrete each television set corresponding; And,, and be sent in the TV remote controller with numbering that they have a preselector memory cell of corresponding relation with combination of the pairing letter character of these television channels or station symbol pattern.Only under the prerequisite that realizes aforementioned two targets; Further in remote controller, realize the demonstration of corresponding letter character combination or station symbol pattern again; With the corresponding function of the numbering of remote controller emission preselector memory cell, then just can realize the present invention the purpose that will reach.Certainly, also can not get rid of foregoingly, television set utilizes the controlled function that cooperates of original preselector and TV tuner.
Based on the above-mentioned problem that will solve, major technique content of the present invention comprises:
1, one side is carried out necessary processing for the TV programme signal source that will broadcast away in the television program broadcasting source; Make and carry letter character combination or the station symbol pattern corresponding in these TV programme signals, to use these letter character combinations or the corresponding TV programme of station symbol pattern-information sign with these TV programme signals.
2, in television set one side; Necessary software and hardware is set; TV programme signal for receiving, carry the letter character corresponding with television channel combination or station symbol pattern is handled; Therefrom extract and preserve these letter character combination or station symbol pattern-informations, in the process of carrying out " searching platform ", the numbering of these letter character combinations or station symbol pattern-information and preselector memory cell, corresponding television channel parameter are set up incidence relation.And; Can utilize the communication interface that has on the television set to carry out the circuit of swap data being provided with on the television set, this circuit can together send these letter characters combinations or the station symbol pattern-information numbering together with the preselector memory cell corresponding with them.
3, in remote controller one side; Necessary software and hardware is set, enables to receive letter character combination or the station symbol pattern-information that aforementioned television set sends, and the numbering of the preselector memory cell corresponding with them; And can show these letter character combination or station symbol pattern-informations; In the time of one among these selected these information of operation, can be via its infrared remote-controlled signal radiating circuit that has, the numbering of the preselector memory cell that this information is corresponding sends to television set.
For foregoing the 1st point; One side need be carried out necessary processing to the TV programme signal source that will broadcast away in the television program broadcasting source; Make and carry front said, corresponding letter character combination or station symbol pattern in these TV programme signals, to use these letter character combinations or the corresponding TV programme of station symbol pattern-information sign with these TV programme signals.For example, in one TV programme signal of central authorities, add " CCTV1 ", perhaps the station symbol pattern-information of one in central authorities shown in Fig. 1-4.Concrete adding mode can mainly be divided into following two kinds according to the type in TV programme signal source:
For anolog TV signals, can adopt teletext technology, in the inverse-range signal of anolog TV signals, add " CCTV1 ", perhaps the station symbol pattern-information of one in central authorities shown in Fig. 1-4.According to the standard of Chinese analog television broadcast, the television screen per second shows 25 frame TV signals, every frame 625 row, and every row is swept to the right side from the left side of television screen, and every frame is divided into two, sweeps to bottom from the screen top.Every frame TV signal 625 the row in actual displayed on television screen have only 575 the row, 50 row of can't see in addition are inverse-range signals.Inverse-range signal also can be used to transmit extra data message the transmitted test signal except being used for usually, comprising: figure, Word message etc.Here it is usually said " teletext ".Teletext utilizes between the TV Field blanking and transmits code signal when transmitting the normal tv program, does not influence normal TV programme, needn't extraly acquire transmitting apparatus.Because adopt coded data to replace writings and image information, transfer rate is very fast.Therefore, in adopting the system of anolog TV signals, can utilize the mode of teletext, the code information that adds and transmit foregoing TV programme at TV programme signal.The technology of relevant teletext can repeat no more at this referring to " teletext and the television data broadcast " of Higher Education Publishing House's 1997 publication.
Certainly; In order to make letter character combination or the station symbol pattern-information that adds in the aforementioned anolog TV signals; Can distinguish mutually with other data, information in the figure message TV signal; Television set is necessary to adopt specific sign that letter character combination or station symbol pattern are identified, so that after receiving figure message TV signal, can therefrom extract letter character combination of the present invention or station symbol pattern.How to confirm as for aforesaid specific identifier, can stipulate, perhaps confirm by the program merchant that the TV programme signal source is provided through industry standard.This is actually letter character combination and/or station symbol pattern, forms the television channel identification information according to certain predetermined form.This way in fact also is the mode of the employing particular communication protocol of general data communications.Such as: aforementioned certain predetermined form can constitute according to following combined sequence:
Station symbol pattern data+the check digit of television channel identification information head (for example: adopt 23 continuous binary zeroes)+letter character combination head information+letter character data splitting+station symbol header+image exchange file format etc. as sign
Must be noted that: traditional teletext information does not have fixing getting in touch with a certain television channel usually.For example: the figure message TV signal that in aforesaid CCTV1 television channel, carries, also can in the channel of CCTV5, CCTV12, carry, and their content can be just the same.But, in the present invention,, can only in the signal of corresponding television channel, carry uniquely, and can not in the television channel of other channels, carry with a letter character combination or a station symbol pattern that the channel TV program is corresponding.
For digital television signal; Can be based on DTV source encoding standard; For example: MPEG2 (Motion Picture Experts Group) standard, H.264 standard (the video compression coding standard of being formulated by joint video team of new generation), digital audio/video encoding and decoding technique standard (AVS) etc. add aforesaid letter character combination or station symbol pattern-information in corresponding digital TV programme video encoding.Regulation according to aforementioned video encoding standard: in the digital television program video encoding, can add field by user oneself definition and use.Therefore; Just can utilize these the self-defining field transmission in the video encoding of digital television program to carry and transmit aforesaid letter character combination or station symbol pattern-information, and realize utilizing among the present invention the TV programme signal transmission letter character relevant of broadcasting to make up the perhaps purpose of station symbol pattern-information with television channel.
Identical with anolog TV signals is: it also is necessary in the video encoding of digital television program, adopting specific sign that letter character combination or station symbol pattern are identified, and can these letter characters combinations or station symbol pattern be distinguished with other user-defined fields like this and come.In addition, also can in video encoding, how adding aforesaid letter character combination or station symbol pattern stipulating, perhaps also confirming by the program merchant that the TV programme signal source is provided by industry standard.Concrete video encoding technology can be referring to relevant textbook or technical manual, standard, for example: " the digital television techniques basis " that " digital television broadcasting principle and application ", the Electronic Industry Press that the People's Telecon Publishing House publishes in September, 2007 publishes in July, 2005, " GY/T 230-2008 digital TV broadcasting service information standard " etc.
In addition; For the digital television program signal; Be not only to be to carry aforesaid letter character combination or station symbol pattern-information in the video encoding; In all links of digital television program broadcasting service; Nearly all can add these information; For example: technical data such as " the digital television techniques basis " that " digital television broadcasting principle and application ", the Electronic Industry Press that publishes in September, 2007 referring to aforementioned People's Telecon Publishing House publishes in July, 2005, " GY/T 230-2008 digital TV broadcasting service information standard ", these information also can be packaged into basic stream (ES), divide into groups basic stream (PES), Program Specific Information (PSI), perhaps in transmission (TS) stream.As for finally how selecting, can be by the personnel that implement the relevant art scheme with reference to relevant technical standard, for example: MPEG2, DVB etc., practical implementation.Reasonable way is to be carried in after the PID, is packaged among divide into groups basic stream or the TS stream.
Obviously, no matter adopting anolog TV signals still is that digital television signal transmits letter character combination or station symbol pattern-information as media, and letter character makes up than the station symbol pattern-information, and it is much little that its data volume is wanted.Therefore; In TV signal, only transmit the letter character combination and come corresponding corresponding television channel just can realize the object of the invention, and can save certain transmission bandwidth, only be to use the have better effect of station symbol pattern-information for the identification television channel; Therefore; Even can sacrifice some bandwidth, also can be in TV signal the more station symbol pattern-information of Data transmission amount, perhaps both together transmit.For example: referring to " microcomputer graphics file format collection " book of Xueyuan Press's in December, 1993 publication; Wherein disclosed image pattern as DIF (Graphics InterchangeFormat; Hereinafter to be referred as: GIF) such computer picture file just can be utilized to write down simultaneously and transmit pattern-information and a spot of character data information.In the standard of gif file, stipulate: the GIF image file can comprise: the application program extent block wherein can comprise user's oneself text data.Certainly, other are any to have and the similar image file format of gif file, also can be used to write down simultaneously, transmit pattern-information and a spot of character data information.Therefore; In TV signal, utilize gif file to transmit letter character combination simultaneously and the station symbol pattern is a kind of reasonable selection; In the predetermined form that can be enumerated in front like this; Neglect " letter character combination head information " and " letter character data splitting ", but they are stored in transmission in the lump in the station symbol pattern of gif file.
