Description

A kind of device and method that is used for television channel management
Technical field
The present invention relates to a kind of radiovisor and method of being used for, relate in particular to a kind of radiovisor and channel management method that receives that be used for moving.
Background technology
At present, along with the development of technology, the especially universal and development of digital broadcast television technology, it is also more and more ripe to be used for moving the radiovisor technology that receives.But, move to be received as and watch that broadcast TV program brings new problem.In the past, television set was to be fixed in local a use, and the signal that it received is also fixed, and the general user just can obtain channel information easily by searching platform or fixed channel table, watched and oneself wanted the program seen.Yet, for mobile TV, if with its from A transform to B ground, because signal changes, the pairing channel table in A ground can not adapt to B ground, just must search the channel table that platform is provided with suitable B ground this moment again, therefrom selects channel to come TV reception again, is not easy to so very much the user and watches in time, fast and oneself want the TV programme seen.
In addition, radiovisor and method can receive broadcast television signal by different modes now, as antenna, and CATV transmission line, or satellite receiver.Each method all is first television channel searching, then channel is stored, because the content of the signal of these three kinds of receive modes transmission has nothing in common with each other, when the user when a kind of receive mode switches to another kind of mode, also must search platform again to obtain current channel information, and the result of search is the channel update of storing former, if switch the original receive mode of meeting again, also need channel searching again, this can not make full use of the resource of TV, concerning the user, use, operate all extremely inconvenient.
Therefore,, be necessary to provide a kind of device of television channel management, make the user when difference makes land used or uses different receive modes, can obtain corresponding channel information easily and efficiently at the problems referred to above.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of devices and methods therefor that is used for television channel management is provided, makes the user can watch local broadcast TV program easily and efficiently when different local, the different receive modes by the broadcast TV channel table of managing each place, variety of way.
To achieve these goals, the present invention adopts following technical scheme to realize: a kind of device that is used for television channel management, it includes receiving system, tuner and the memory of CPU control.Wherein, store memory contains two covers or the above programme channel table of two covers is selected a wherein programme channel table that overlaps as current use for the user by certain way, and selects a cannel broadcast from this channel table.
Channel information under the channel information of each geographic area or the every kind of receive mode all gives organization and administration as a cover channel table.For a television set, its channel table of storing can be some covers, corresponds respectively to above-mentioned different geographic area or different receive modes.
In memory, can distribute fixing memory space to every cover channel table, also can be to the variable memory space of every cover channel table dynamic assignment.The present invention has adopted two kinds of dynamic management approachs, and first kind of dynamic management approach is the channel in each cover channel table to be mixed be stored together, and each channel is provided with a channel table attribute and is used to represent which channel table this channel belongs to.Second kind of dynamic management approach is that the positional information of all channel tables is concentrated management, and the sets of channels of each channel table correspondence is stored together.Wherein, above-mentioned positional information can comprise the original position of channel, the channel number that is comprised, or both combinations.
Wherein, each channel data can be obtained by television channel receiving system and the external equipment mode by data communication.
A kind of method that is used for television channel management, implementation step is:
The channel table of channel table as current use overlapped in a, selection one;
B, channel searching;
C, the channel that searches are set to the attribute of current channel table;
D, above-mentioned channel information is left in the memory.
Wherein, can store two covers or the above channel table of two covers in the memory, each overlaps channel table and corresponds respectively to different receive modes or different geographic regions.Comprise several channels in every cover channel table, for each channel, it includes relevant parameters such as channel frequency parameter, channel identification information again.
Under the situation of changing place and receive mode, local or current channel table need be set, start for the first time need repeat above-mentioned step channel table and channel information are set, and after setting, can situation as required select corresponding channel table.
In memory, can distribute fixing memory space to every cover channel table, memory space that also can channel table is set to dynamically changeable.
Wherein, for the dynamic management approach of first kind of channel table, the channel in all channel tables can be mixed being stored together, each channel is provided with a channel table attribute in order to corresponding with corresponding channel table institute.Under this cynamic channel management method, the mode of selecting a cover channel table is to adopt menu-style, by searching for all channel tables, forms the tabulation of an existing channel table, and the user therefrom selects one again.
Under the dynamic management approach of above-mentioned channel table, channel can sort by the channel table attribute, and the channel that all channel table attributes are identical puts together, and the result after will sorting writes the channel gauge outfit.This ordering work can be in the AV pattern, the PC/DTV pattern, and holding state waits non-channel to finish in the operating time.
For the dynamic management approach of second kind of channel table, can be to the channel position information unified management of all channel tables, its positional information can be an original position, channel number, or the combination of the two.At this moment, if upgrade channel table information, carry out channel search in a manner mentioned above earlier, if the channel number that searches out and different in the past then needs special processing; If the channel that searches out is than former lacking, need will be thereafter all channel tables to reach, and empty all data that last channel table ending place is stored in the memory; If the channel that searches out is than many in the past, need all channel tables are thereafter moved backward, after finishing, the number that searches out channel is write the pairing extension position of this channel in the channel gauge outfit.
For the dynamic management approach of second kind of channel table, the mode of selecting a cover channel table is to adopt menu-style, and the channel designation that the channel gauge outfit is comprised reads, and forms the tabulation of an existing channel table, and the user therefrom selects one.
After having adopted the present invention, commute A ground and B ground or more location, only need to each setting of each local channel table once just can therefrom select suitable channel table and watch local program easily when the user carries this device; When perhaps the user was switched receive mode, only a channel table need be set can select suitable TV programme, thereby avoided each troublesome operation of searching platform again.

Embodiment
As shown in Figure 1, this simulated television receiving system comprises: digital tuner, MCU (MicroprogrammedControl Unit, microprogram control unit), image and sound accompaniment processor, a row drive circuit, E 2PROM, audio driven, picture tube driving, audio amplifier, display, receiver of remote-control sytem and remote controller.Tuner is tuning by MCU control, and the composite video signal of its tuning generation drives by the picture tube outputting video signal through the space field, and audio signal is exported by loud speaker.MCU comprises that also the ROM memory is used for the TV software program of storing driver whole TV system with operate as normal.Memory E 2Some relevant settings of the tuning data of each channel of storage and this channel among the PROM.Receiver of remote-control sytem is used to receive the control command that sends from remote controller, and it is transferred to MCU, and subsequently, MCU promptly controls E to this command response 2The selection and the storage of PROM mid band tuning data.
Shown in Figure 2 is the digital television receiving apparatus schematic diagram, and it comprises MCU, tuner, E 2PROM etc.Wherein, MCU, E 2Control by the I2C bus between PROM and the tuner.At E 2There are some relevant settings of tuning data and this channel of each channel in the PROM.
For each channel, it includes channel frequency parameter, channel identification information and other useful informations such as S-SYSTEM, sound standard or the like.
At E of the present invention 2The PROM internal memory contains some cover channel tables, Figure 3 shows that the E that programme channel table length is fixing 2The PROM planning table.If at E 2Set 300 channel spaces in the PROM and plan that then in the present embodiment, the space of 100 channels of each channel table fixed allocation can be supported 3 channel tables so altogether.As the current channel table, this moment, as the channel setting, skipped to the operation of channel by channel according to one of them channel table of ground point selection of its use for radiovisor, and channel exchanges, and the channel navigation setting is searched platform etc. and all finished in the current channel table.Adopt this E 2The PROM storage mode is simple to operate, is easy to realize, but because the distribution method of each channel table memory space is more stiff, to E 2PROM utilizes not science.
In order rationally to utilize limited E 2The PROM memory space makes it can support more channel table, can adopt the dynamic management of channel table.Two kinds of methods are arranged among the present invention.First method is all to give a channel table attribute to each channel, and which channel table this channel of this attribute representation belongs to, and with the same storage of other data of this channel.Figure 4 shows that the programme channel data comprise the E of channel table attribute item 2The PROM planning table.After selected certain channel table was as the current channel table, the channel table attribute was that all channels of this channel table will constitute a set in total channel table, and the operation of all relevant channels is all carried out in this set.Channel table can be deleted, and the subordinate channel Table Properties that belongs to all channels of this channel table after the deletion all will be cleared.Equally also can a newly-built channel table, the channel that all channel table attributes are cleared can be set as and belong to this channel table.If a newly-built channel table, as long as the current channel table is set as the channel table attribute that certain is not used, search platform then, the channel that searches out can be saved in the channel that the channel table attribute is cleared, and is taken up to the channel space.This method is more flexible, also is easy to realize, but the channel skewness of same channel table, it is more time-consuming to search channel.
The dynamic management approach of second kind of channel table is that its positional information can be an original position with the channel position information unified management of all channel tables, and channel number, or the combination of the two are chosen the channel number here.Shown in Figure 5 is exactly the E that the programme channel data comprise each channel table length 2The PROM planning table.At this moment, the head of channel table has comprised the information of channel table, comprises the number of the channel that the title of each channel table and this channel table are comprised, and keeps for the information of channel table head can be suitably more.After the channel gauge outfit is each data of showing frequently, and beginning is the information of first first channel of channel table.First channel table is the information of second channel table after finishing, the rest may be inferred channel information to the last.Just can learn the original position of its channel table and the position of corresponding channel from the channel number that the channel table head is comprised.
Channel table for regular length, because the number of channel table is fixed, the length of each channel table is also fixed, and its process of searching platform is similar to existing radiovisor, unique different be before searching platform, to select a channel table as the current channel table.But the platform of searching of the channel table of dynamic management uses and has now mode and has more different.Describe the process of setting up of the channel table of dynamic management below in detail.
When using radiovisor at first, the E that it is inner 2Do not store any channel data among the PROM, and the number of channel table is 0.The management of channel table has the content of following several respects: 1, a newly-built channel table: 2, refresh a channel table; 3, select a channel table as current channel; 4, channel table of deletion; 5, channel table name management.
It at first is a newly-built channel table.For the dynamic management approach of first kind of channel table, newly-built channel table meaning has started one and has searched the platform process.Search platform from first channel of channel table, if current channel is empty, the platform that then newly searches out can write its shared memory space, and the channel table attribute is made as the current channel table, writes related data otherwise seek next channel forward for empty memory space.Begin to search for next platform then, and the like, up to having searched platform or institute has living space and all taken.For second method, the platform of searching of newly-built channel table is that last begins from the ending of current existing channel table, searches out first and just writes above-mentioned position, whenever searches out a platform later on, just write next position successively, up to searched platform or have living space and all taken.After finishing, the number that searches out platform is write its pairing extension position in the channel gauge outfit.
Be to refresh a channel table then.For the current channel table that is using, because signal changes, the user need refresh channel information, can search for all channels again.For first method, its searching method is from first channel, whenever searching out a channel just writes data the channel table attribute and is empty platform for the platform of this channel table or channel data, search for next platform then, after searching out, in channel table, find next channel table attribute to be empty platform for the platform or the channel data of this channel table, write channel data, the rest may be inferred, searched all platforms after, remove that all properties is the platform of this channel table in the channel table thereafter.For second method, can bother a little than first method.It is the same searching the mode that platform begins and the platform mode of searching of newly-built channel table, if when the platform number that searches out and different in the past, needs to handle especially.If the platform that searches out is than former lacking, needs general's all channel tables thereafter to reach, and empty last channel table ending place all data to the 300th platform.If the platform that searches out is than many in the past, need all channel tables are thereafter moved backward.After finishing, the number that searches out platform is write the pairing extension position of this channel of channel gauge outfit.
The mode of selecting a channel table is the form by menu.For first method, at first search for all channel tables, form the tabulation of an existing channel table, the user therefrom selects one.For second method, because a channel gauge outfit is arranged, the channel designation that only needs the channel gauge outfit is comprised reads, and forms the tabulation of an existing channel table, and the user therefrom selects one.
For channel table of deletion, as long as first method is the data dump of the platform of this channel table with all channel table attributes in all channel tables.Second method also will be with all channel table data reaches thereafter except emptying.
The channel table name needs, because can make things convenient for the user to manage.The name of first method need be opened up a memory space in addition.Because the channel table attribute is unique,, generally be a numeral for conserve space.At each numeral that the channel table attribute is comprised, can specify a name space for it, edit generation by the user.Second method only needs to get final product at each channel table name because head has the channel table title.
For two kinds of top dynamic management approachs, can learn from other's strong points to offset one's weaknesses obtains a kind of more rational management method.Only all channels of first method management need be sorted by channel table, the platform that all channel table attributes are identical puts together, and the result after will sorting writes the channel gauge outfit, makes the channel table order of channel gauge outfit the same just passable with the PS in the channel table.Because ordering work is a time-consuming procedure, ordering work can be in the AV pattern, the PC/DTV pattern, and holding state waits non-channel to finish in the operating time.
Generally, the user is on A ground, and a newly-built channel table A after search is finished, forms channel table A.On B ground, a newly-built channel table B after searching platform and finishing, forms channel table B.If the user carries radiovisor on A ground, select channel table A as the current channel table, if to B ground, select channel table B as the current channel table.When the user frequently commuted A ground and B ground, it was conveniently well imagined.This is that channel table is organized by the region.
In addition, general radiovisor, can receive by antenna, also can pass through the cable TV received signal, or satellite receiver, the content of these three kinds of signal transmission is also inequality, and the user can preserve three channel tables simultaneously on a receiving system, and the user only needs each setting once just can switch these three kinds of receive modes very easily and need not search platform again.This is that channel table is organized by signal type.
Certainly organizing of channel table also can be dual mode line and staff control by top, as A ground antenna channel table, and A ground cable channel table, B ground cable channel table etc.
For broadcast receiver, it with the radiovisor principle on be the same, adopt similar method also can realize.
Equally, analog TV broadcasting receiving system and digital broadcast television receiving system, they are basic identical in the management of channel, above described method can be suitable for for the two.
Channel table data of the present invention can be by storing in the program or E in advance 2Among the PROM, perhaps by data communication, as the serial line interface of standard, USB interface, wireless telecommunications, perhaps self-defining communication modes is perhaps obtained by the receiving system decoding in broadcast television signal by loading these data.
Certainly, the present invention also has other multiple implementation methods, and as the channel that each channel table comprised is adopted chained list, methods such as concordance list are organized.
