Embodiment
Fig. 1 is the system framework figure of the optimum implementation on simulated television of the present invention.It has comprised MCU, tuner, EEPROM, remote control receiving unit, output of Voice ﹠ Video or the like.Wherein tuner is digital tuner, and it is divided into two kinds of voltage synthesis mode and PLL frequency synthesis modes, and its corresponding channel selection data are exactly tuning voltage and frequency dividing ratio.This programme adopts frequency synthesis mode tuner, and the channel selection data are frequency dividing ratio.Pass through I between MCU, EEPROM and the tuner
2The C bus is controlled.If watch which channel, MCU just obtains the channel selection data (frequency dividing ratio) of this channel and it is sent to tuner from EEPROM, and after tuner was received the channel selection data, the fixing intermediate-freuqncy signal of output was used for the rear end.
All channels all were stored in the EEPROM channel selection tables of data after TV was searched platform.In China, channel bandwidth is 8M, general tuner, and same channel selection data that obtain do not differ can surpass 50K.If therefore the channel selection data of two channels differ in certain limit, we can assert that these two channels are same set of programs, like this can be general about the setting of this two programs.It judges flow process as shown in Figure 3.General this difference is defined in the 1M scope just passable, and it can be littler certainly, mainly depends on the sensitivity of tuner and decoding unit.
Receive decoding for Digital Television, generally finish by digital TV set-top box.Composition frame chart is by shown in Figure 2, and it also comprises MCU, tuner, and EEPROM, etc.Pass through I between MCU, EEPROM and the tuner
2The C bus is controlled.Distinguishing different channel can carry out according to the mode of above-mentioned simulated television.Because the particularity of Digital Television, it can be loaded into channel information in the signal, in decoding information reverting is come out.Like this, MCU obtains just can judging whether two channels are identical after the information.Equally, also the unlabeled data of each channel can be put in the EEPROM.If the unlabeled data of two channels is identical, assert that then these two channels are same channels and carry out associative operation.According to " digital TV broadcasting service information (SI) standard ", can comprise such message segment in network information table (NIT) lining, as transmit the stream identifier, channel frequence, the satellite launch vehicle number, modulating characteristic, version number etc., we can select one or multinomially be used as the judgement that the channel information specific is carried out same channel.It judges flow process as shown in Figure 4.
No matter be simulated television or Digital Television, the bandwidth of its channel is a certain value.In China, bandwidth is 8M, and therefore, the carrier frequency difference between any two channels should be more than or equal to 8M.If it is very little that two carrier frequency data are separated by, as 1M, such channel is non-existent in the reality, if there is such channel in the channel table of television set, can assert that these two data are same channels.For the user, as long as certain channel has a piece of data just much of that.
Based on last surface analysis, the broadcast TV channel filtering technique is exactly the relevant channel channel selection data of comparison in tv channel list, sees that its difference is whether in certain scope, if in certain scope, then think same channel, so just delete or skip one of them channel.Specific implementation as shown in Figure 5.
If the setting at deleted channel is arranged in program navigating, displaying predetermined programme, time management, hobby program, then setting deleted or that skip channel is composed to the channel identical with it with certain rule.In addition, S-SYSTEM, sound standard, beautiful sound are selected or the like, so long as the setting relevant with channel can be composed to same channel in some way as the information that needs protection.
Because program can be made as default value with the setting of each channel of searching out when automatic channel search, and considers that channel order can change, and therefore can dispose contents such as program navigating, displaying predetermined programme, time management, hobby program.Like this, the former data of setting up of user have just been lost.But generally speaking, the variation of channel is limited, and this variation comprises the adjustment of TV signal, searches platform hardware system and the uncertain factor of searching the platform program, or the like.Therefore, Wu Duan deletion will inevitably cause inconvenience to the user.The relevant part of searching platform of the present invention has been considered user's this demand.Data in the channel table are arranged from low to high by frequency, whenever search out a platform after, seek identical with it channel in the channel table, if having, then the setting of all relevant these channels is composed to the channel that newly searches out by certain way.In the time of automatic channel search, generally be to begin to search platform to high band from low frequency end, after searching out first platform, the platform that newly searches out is designated as A, and in the channel table first is designated as B, and both compare, according to above-mentioned standard, if A is identical platform with B, then being provided with of all relevant B composed and give A, preserve A then to the position of B; If more than the little 8M of frequency of A than B, B is moved the end of channel table, and it is caused about variation is set to upgrade this change in location, preserves the move preceding position of A to channel table B then; More than the big 3M of frequency of A than B, then directly preserve A to the position of B.Whenever after searching out a platform later on, also will compare in top mode, just the data that will compare not only comprise current channel, also comprise moving the last data of channel table.At first, with the channel that just searched out and current channel relatively, if same channel, then all are provided with to compose and give the platform that has just searched out with this channel, because the frequency of moving the channel table end is littler than current certainly, all delete; If more than the little 8M of frequency ratio current channel, then current channel to be moved the channel table end, and compare with the remaining channel at channel table end, the channel that frequency is identical is provided with to compose and gives the channel that has just searched out and preserve, and deletes all then than just searching out the little channel of platform frequency.Like this, when searching after platform finishes, Useful Information is just saved from damage.It is realized as shown in Figure 6.
For digital broadcast television, at first it can utilize the channel selection data as criterion, secondly because the amount of information that digital broadcast television carries is more, can load some channel information data in signal, like this, utilizes these data just can come channel-identification.Its usage just has only identical and different two kinds of selections to top similar in relatively.When channel filters, if channel is identical, then save information from damage, delete one of them channel.When searching platform, save information from damage if channel is identical, otherwise deletion.
In order to allow the user setting of relevant channel can be become default setting, in menu, can allow the user be chosen in and search whether save information in the platform process from damage.
Should comprise S-SYSTEM with the setting of channel, the sound standard, frequency range is at beautiful sound selection, CCD selection and the V-CHIP setting of certain channel, displaying predetermined programme, program navigating, channel designation, index setting, skip and be provided with etc., new setting or way to manage may be occurred in addition, only otherwise break away from its spirit, scope of the present invention all should be belonged at channel.
