Do not list whole television channels that the Beijing area can be watched in the table 1 shown in above being noted that.In the superincumbent table 1, TV station's name represents to carry out the title of the TV station of television broadcasting, the channel designation of wherein useful English alphabet abbreviation, and for example the platform name of each channel of the Chinese Central Television (CCTV) is represented with " CCX ".Platform name with the abbreviation of phonetic transcriptions of Chinese characters captions is also arranged, for example, " BJ " of BTV, " GD " of Guangdong Television etc.In addition, if there are many cover TV programme in certain TV station, can after the abbreviation of platform name, add the numbering of tricks of the program of TV station.For example, " Beijing five covers " can be expressed as " BJ5 ".
Above-mentioned central authorities and provincial 's identification code can once be set in the storage chip of television set by encoder, and the user also can be provided with voluntarily one by one according to coding schedule.
According to the remote control method of channel selection based on Pinyin coding of the present invention,, the Pinyin coding of corresponding TV station should be set at first if the user wishes to utilize phonetic to carry out channel selection.Then, be input in the storage chip of television set with the corresponding coding of Pinyin coding TV station set.After this, when the user wishes to utilize the phonetic mode to carry out channel selection, only need under phonetic channel selection pattern, to press the respective keys of representing letter and number and can select required television channel.
According to coding method of the present invention, for example, the table 1 that provides from above as can be known, if the user wants to watch the program of " Chinese Central Television's second cover ", only need under spelling mode, press twice of numerical key represent alphabetical " C ", and the numeral " 2 " of representative " two covers " once, and promptly push button " 112 " can select the program of the Chinese Central Television's second cover.Remote controller will output to television set with the push button signalling that the user presses.Television set finds the television channel corresponding with " CC1 " in the coding schedule of its memory stores, TV programme can be switched to user-selected channel subsequently.In another example, if the user wishes to select the program of " BTV's the 5th cover ", coding method by Pinyin coding, the user knows that with " BTV's the 5th cover " Pinyin coding that program is corresponding be " BJ5 ", the user only need press the numeral " 145 " on the remote controller under spelling mode, that is, just can choose required television channel by three buttons.Forget the channel that required TV programme is corresponding with the user, and the situation of utilizing the numerical key of remote controller to search for compares, significantly reduced touch potential, and accelerated the speed of channel selection.
In addition, as can be seen, also there has been the situation of repeated code in the Pinyin coding in the table from top table 1.For example, respectively corresponding " ShX " and " ShX " its coding of the phonetic of " Shan Xitai " and " Shan Xitai " is " 0X ", promptly corresponding and numerical key " 08 ".In this case, the phenomenon for fear of repeated code appears in two TV stations the coding of " Shan Xitai " can be changed into " SX ", and the coding of " Shan Xitai " still is " ShX ".Like this, if the user selects " Shan Xitai ", then under spelling mode, press numeral " 78 "; If select " Shan Xitai ", then press numerical key " 08 ", thereby avoided coincident code problem.In addition, according to the present invention, for not causing situation about obscuring, numerical key " 0 " also can be represented "? h ", wherein "? " can represent " Z " respectively, " C " and " S ".In addition, numerical key " 0 " also can be represented " n " or " 1 " so that southerner's pronunciation custom.In addition,, also numerical key " 0 " is set to representative " Hu ", to reduce the situation of repeated code for the ease of distinguishing the pronunciation of " lake (Hu) " and " river (He) ".In this case, if the user selects " Hu Beitai ", its corresponding codes is " HuB ", and the numerical key that need press is " 01 ", if the user selects " He Beitai ", its corresponding codes is " HB ", and the numerical key that need press is " 31 ".
The another kind of situation problem that to be the program of distinguishing certain TV station occur when ten covers or ten covers are above.For example, for " Chinese Central Television (CCTV) ", broadcast tens programs its every day.For example, in order to distinguish " Chinese Central Television's first cover " program and " Chinese Central Television's the 11 cover ", the program of " Chinese Central Television (CCTV) the 11 cover " etc., promptly distinguish Pinyin coding " CC1 ", " CC11 ", " CC12 ", as an embodiment, its solution is can select to carry out timing by the controller that is provided with in television set time interval to button when the user presses button at every turn, has surpassed predetermined duration if press the time interval of button, thinks that then the button input finishes.For example, when the user after pressing numerical key " 111 " under the spelling mode, if at the fixed time in the interval, for example 2 seconds, do not continue to press button, the controller of television set judges that then the television channel that the user will select is " CC1 ", promptly, " Chinese Central Television's first cover " program, and switch to corresponding channel.If the user preset time at interval in, for example in 2 seconds, continue to press numerical key, then accept the code signal of back, the code signal that itself and front have received is considered as a whole, in table, find the TV station of correspondence.Yet, the invention is not restricted to this, also can adopt alternate manner to distinguish.
Above-mentioned cataloged procedure is equivalent to Hash (Hash) table in fact,, searches object element fast with a cover keyword that is.The design principle of Hash key is to reduce the repetition rate of coding as far as possible, also is the probability of the corresponding a plurality of object elements of same code word.If N is coding sum, N
cBe the number of repeated code, L
eBe mean code length.The repetition rate of coding is calculated by following formula:
Mean code length calculates by following formula (2):
L wherein
iBe the length of i coding.
In the superincumbent table 1, repeated code is counted N
c=0, so repetition rate of coding R
c=0, also promptly be an optimum code scheme at present; Mean code length is 2.3, also is the selection that average 2.3 buttons promptly can be finished a channel.Compare with scan situation about pressing with numerical key, greatly reduced the number of times of button.
According to the present invention, the user can be the TV station that does not list in a certain channel or the coding schedule, and for example local broadcasting stations define or deletion channel another name.In order to carry out this two operations, at first, turn on the television set Administration menu by remote controller " menu " key then with the channel of digital channel selection mode switch to the definition of will encoding.
Fig. 2 shows the schematic diagram of setting menu according to an embodiment of the invention.Setting menu can be multilevel menu.When the user will carry out " another name management ", the menu key of pressing on the remote controller entered the setting menu.Next stage menu shown in selection " another name management " item enters, television set operating system is called corresponding hypervisor.Enter the menu of " setting another name " and " deletion another name ".When the user will delete the current another name that is provided with for corresponding TV station, can select " deletion another name ".For example, as shown in Figure 2, built-in " Shandong TV Station " of " SD " expression system wherein, " SDXL " then may be the abbreviation of user-defined " the legend of condor hero ", represent that present Shandong TV Station plays " the legend of condor hero ", be the another name of Shandong TV Station place channel, press digital alphabet key " SDXL " after, promptly selected " Shandong TV Station " of broadcast " the legend of condor hero ".Press definite key after selected " SDXL ", can delete the another name " SDXL " of " Shandong TV Station ".Equally, the user can set new channel coding by setting menu.
Specify the step of setting another name and deletion another name below respectively.It is as follows that another name is set step:
1) with figure pattern, spelling mode, or enter a certain channel that will set as current channel by modes of operation such as channel increasing-and-decreasing keys;
2) press remote controller " menu " key, open the setting menu, enter " another name management-setting another name " menu item;
3) press the digital alphabet key of remote controller, inputting channel another name coding, i.e. Dui Ying phonetic alphabet;
4) content of affirmation input, in order to reduce number of keys, can be with the directionkeys on the right, normally in volume increasing-and-decreasing key and the channel increasing-and-decreasing key is defined as acknowledgement key; Withdraw from the setting menu, in order to reduce number of keys, can be with the directionkeys on the left side, normally another in volume increasing-and-decreasing key and the channel increasing-and-decreasing key is defined as ESC Escape.
Another name deletion step is as follows:
1) with figure pattern, spelling mode, or enter a certain channel that will set as current channel by modes of operation such as channel increasing-and-decreasing keys;
2) press " setting " key of remote controller, open the setting menu, enter " another name management-deletion is called " menu item, select an existing another name;
3) content of affirmation deletion, the definition of acknowledgement key is as mentioned above; Withdraw from menu, the definition of ESC Escape as mentioned above.
After the user sets the another name of corresponding TV station, its another name encoding scheme may with the defined coding repeated code of system, clear up mode according to foregoing repeated code cleared up this moment.
Describe below with reference to Fig. 3 and to carry out the internal structure of the television set of remote control channel selection based on phonetic transcriptions of Chinese characters according to inventive embodiments.For ease of description, the part that has nothing to do with content of the present invention in the not shown television receiver, and omitted its description.As shown in Figure 3, according to embodiments of the invention, television set inside comprises infrared receiving circuit 1, screen display drive circuit 2, tuning circuit 3, interface circuit 4, storage device 5, controller 6 and communication interface 7, infrared receiving circuit 1 receives the command signal that the user sends from remote controller, and is sent to controller 6 by interface circuit 4.Screen display drive circuit 2 drives display screen and shows the corresponding information of importing with the user of instruction.For example, when the user utilizes Pinyin coding to select TV station, occurring under the situation of repeated code, showing the alternative candidate TV station that the coded message imported with the user is corresponding.Interface circuit 4 is used to the related circuit of television set inside that interface is provided, and carries out corresponding conversion of signals.Memory 5 storage Pinyin coding tables and coding-channel map (hereinafter describing) of downloading from encoder, and required program and other data necessary of operation of the related circuit of controller control television set.As an example, memory 5 can adopt EEPROM (Electrically Erasable Programmable Read Only Memo) (EEPROM) etc.The operation of various piece in the controller 6 control television sets.Controller 6 produces harmonic ringing by interface circuit 4, is used to produce screen pattern output.In addition, controller 6 is also downloaded coding-channel map by communication interface 7 from encoder.
The following describes according to the present invention, utilize Pinyin coding to realize the manipulation of TV programme channel selection.When the user turned on television set, the default channel selection pattern of television set was digital channel selection pattern.Under digital channel selection pattern, the user can directly select channel by the channel number font size.As mentioned above, numerical key " 0 " is set to mode switching key.For example, under digital channel selection pattern, " 0 " key of remote controller is pressed odd number, enter phonetic channel selection pattern, press even number and return digital channel selection pattern.Under phonetic channel selection pattern, the user gets final product by the channel code word that defines in the digital keys input Pinyin coding schedule on the remote controller, shows the optional channel list under the current keystroke sequence simultaneously on the television screen synchronously.The user can use " channel (number) increase " and " channel (number) minimizing " key on the existing remote controller to change channel at any time.The following describes when repeated code has taken place for user's self-defined setting and default, how to select the television channel of wishing.
Shown in Fig. 4 a, when the corresponding different channel of same Pinyin coding, repeated code promptly takes place, at this moment, on video screen, show and the pairing TV station of this Pinyin coding name.Fig. 4 a shows and has three examples with the pairing TV station of this Pinyin coding name.According to the present invention, controller 6 automatically switches to first channel in the repeated code channel list, and (for example upper right corner) shows the expression candidate information on screen, shown in the runic frame among the figure.The runic frame table shows the program of in progress first repeated code channel on the current screen.Do not wish the channel watched if the program of first repeated code channel that shows on the screen is not the user, can select other candidate channel by pressing " channel increase " and " channel minimizing " key.Fig. 4 b shows the displaying contents of pressing screen behind " channel increase " key.As we can see from the figure, current channel has switched to the program (frame of numeral 2 has become the runic frame) of second repeated code channel.Surpass the scheduled time if the user stops on a candidate channel, for example, 1.5 seconds, 6 of controllers confirmed that the user has selected current candidate channel.
Usually, cable television operators are modulated on the different channel shown in the table 1 after satellite received television program downstream signal and demodulation again.The regulation of China's Mainland cable television channels resource is as follows:
| DS1-5 | ?Z1-7 | ?DS6-12 | ?Z8-16 | ?DS13-68 | ?Z17-35 |
Wherein DS represents the standard channel, and Z represents the additional channel of cable TV, and each channel accounts for the frequency range of 8MHz.
Memory encoding-channel map in the storage device 5 of television set inside.Usually, the channel arrangement of different regions is also inconsistent, but after arranging to determine, just remains unchanged basically (when new program is arranged, then may arrange new channel).Consider that TV station cited in the table 1 all can watch in most of place in the China's Mainland, so can set up a coding-channel map shown in theing contents are as follows:
The Dian Shitai channel of encoding
…… ……
Central authorities one the cover CC1 Z3
…… ……
This form has represented how the coding of user's input is mapped on the television channel, and by set up such table in television set storage device 5, television receiver just can jump to definite channel.For example, if the user wants to watch the program of " central authorities' one cover ", under spelling mode by pressing digital alphabet key " 111 " corresponding with its Pinyin coding " CC1 " on the remote controller to television receiver transmission channel selecting signal.Television receiver is searched the coding-channel map of storage device 5 storages after receiving this signal, and jumps to corresponding channel Z3.
As previously mentioned, because the different channel use table that cable television operators arranged and inconsistent, so need to use encoder that the channel use table that cable television operators provide is input in the television receiver, under the default situation, code table can be sky.Encoder can and be responsible for by the television receiver dealer maintenance television receiver of selling is encoded.
In Digital Television, owing to can carry station symbol information in the digital television program signal, so coding-channel map can be generated automatically by the CPU in the television set.
Encoder can be formed by any computer development that possesses standard communication interface.Encoder comprises following two functions: 1) operator is sent to (programming mode) in the encoder to coding-channel map by computer; 2) operator is written to (distribution mode) in the television receiver to the coding-channel map of storage by encoder through the communication interface 7 of television receiver.As an alternative, also encoder can be arranged in the television receiver, and by external equipment, for example network downloads to coding-channel map in the storage device 5 of television receiver.
In order to realize Pinyin coding channel selection function, the hypervisor of television receiver need be done following change.At first, a channel selection pattern variable is set, the channel selection pattern that recording user is current.This pattern can be made amendment by " channel selection pattern " key (for example, numerical key " 0 " can be set as channel selection mode switch key) by the user.When the hypervisor of storing in the television set receives the user to the channel selection order,, select different processing paths (will be described later) according to current channel selection pattern.When the user carried out alias definition or deletion action, hypervisor was carried out different processing paths.If the another name of user definition TV station, television receiver receives the another name of user's input, and is written in coding-channel map.If deletion another name, television receiver are followed the tracks of the menu selection that the user carries out, locate another name to be deleted, and from coding-channel map, delete this.
Carry out the operating process of remote control method of channel selection according to the embodiment of the invention based on phonetic transcriptions of Chinese characters below with reference to Fig. 5 explanation.At first, when the user presses digital alphabet key 0-9 on the remote controller or "/--" key, judge that at step S501 current channel selection pattern is figure pattern or spelling mode.If the judged result among the step S501 is a "No", then detect whether imported the instruction of channel selection mode switch at step S502.If the judged result among the step S502 is a "No", then continue to carry out traditional digital channel selection process at step S503, and in the switching of step S505 according to the digital channel number execution channel of user's input.If detected the instruction of channel selection mode switch at step S502, this process proceeds to step S504, and current channel selection mode switch is arrived spelling mode, and confirms to handle successfully, finishes handoff procedure.
In step S501, if judge that remote control channel selection mode is to be under the spelling mode, this process is then rotated step S507.In step S507, whether the instruction that detects user's input contains the mode switch instruction, under spelling mode, when user's input " 0 ", and when not having follow-up input at the appointed time, judging that the user has sent the mode switch instruction, is figure pattern with the channel selection mode switch.After this process forwards step S506 to, enters digital channel selection pattern, and confirms manipulation process to finish handoff procedure.In step S507, if the user utilizes Pinyin coding to import the TV station that wishes selection, then filter step S508 pair of TV station's name corresponding with the coding of user's input, that is, find out all TV stations corresponding as candidate TV station with this coding.When the user selects not finish or has repeated code, have a plurality of possible candidate's platforms in the candidate list.Therefore, filter candidate list according to the button input that the user is each legal, keep possible candidate, its detailed process will be described later.At step S509, whether the quantity of judging candidate TV station is greater than 1.When the quantity of candidate TV station is zero, the not TV station corresponding with the Pinyin coding of being imported is described, that is, there is not legal candidate, this process finishes.If determine that at step S509 candidate quantity is 1, flow process then forwards step S511 to, searches corresponding channel in the coding-channel map of storage device 5 storages, and carries out tuning in view of the above.After finding corresponding channel, flow process forwards foregoing step S505 to, carries out channel and switches, and finish the channel selection process in channel selection success back.
When judging candidate quantity at step S509 greater than 1 the time, flow process forwards step S512 to, judges whether the process of searching the candidate platform is finished.After if the user imports the button of some, still have a plurality of candidate's platforms, and can not distinguish by follow-up input the time, it is complete to think that then the candidate has imported, flow process goes to step S510, carries out repeated code and clears up.It is by provide candidate's menu, the process that allows the user select on screen that repeated code is cleared up.Its concrete operations are described in front.Execute after repeated code clears up at step S510, if only remaining sole legal candidate, flow process then forwards step S511 to, searches final channel by inquiry coding-channel map, and carries out tuningly in view of the above, carries out later step.
Remain unfulfilled if judge at step S512 that the candidate platform is searched, then read the next button of remote controller input at step S513.After this, flow process forwards step S514 to, judges whether the button of input is legal, if the button of input is illegal, then determines no legal candidate platform, and finishes this process.On the contrary, if determine that at step S514 the button input is legal, flow process then proceeds to step S515, judges with this whether the time interval of pressing button is overtime.If the judged result of step S515 is then determined no legal candidate platform, and is finished this process for certainly.If the judged result of step S515 is for negative, flow process is then returned step S507, detects whether to receive the mode switch instruction.
Describe the method that the candidate among Fig. 5 filters in detail below with reference to Fig. 6.At first, in step S601, import a button.Judge at step S602 whether the inspection to candidate list finishes.If the inspection of candidate list finishes, then finish candidate and filter, and show the channel of selecting.Be not over yet if judge the inspection of candidate list, flow process then forwards step S603 to, takes out a candidate platform from candidate list.After this, flow process proceeds to step S604, and whether the individual code character of the i of the candidate platform that judge to take out (i be greater than for 1 natural number) is consistent with the character of input.If the judged result of step S604 shows that i character of the letter corresponding with the button of input and this candidate is inconsistent, then delete this candidate at step S605.If the judged result of step S604 shows two character unanimities, flow process is then returned step S602, continues to judge whether the inspection of candidate list finishes, and clears up repeated code with this, obtains filtered candidate platform.
