Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The embodiment of the invention is by setting up second tuner in television set inside, when control first tuner carries out the broadcast of TV programme, control second tuner on the backstage according to the channel search update instruction and carry out the automatic search of channel and the renewal of channel data, easy to use.
The embodiment of the invention provides a kind of program channel update method, sees also Fig. 1.
In step S101, when control first tuner carries out the broadcast of TV programme, judge whether to carry out the automatic search and the renewal of program channel, when needs carry out automatic search of channel and update functions, carry out step S102, otherwise normal TV reception.
In step S102, receiving channels search update instruction.
In step S103, control second tuner according to the channel search update instruction that receives and carry out the search of program channel and the renewal of channel data.
Because the television set that the embodiment of the invention provides includes two tuners, wherein first tuner is used to support the normal play TV programme, second tuner is used for the automatic search and the renewal of support channel, and, when two tuners carried out work simultaneously, the high-frequency signal that television set receives antenna was distributed to two tuners of TV inside accordingly.
In specific implementation process, the input signal of two tuners all is duplicate high-frequency signal.
In step S104, after the tuner that carries out channel search searches channel information, judge at first whether this channel exists.When the channel that searches exists, proceed search, when the channel that searches does not exist, carry out step S105.
In step S105, this channel data is stored to memory, and proceeds search.
Like this, the user is TV reception on one side, carries out the search of program channel on one side, promptly TV reception with carry out channel search and carry out simultaneously, convenient for users.
The embodiment of the invention also provides a kind of television set, sees also Fig. 2, and this television set comprises MCU, and this television set also comprises first tuner and updating program frequency channel data device.
Wherein, under MCU control, first tuner is supported the normal play of TV programme.
When the normal TV reception of user, first tuner sends to intermediate-frequency circuit portion with the programme signal that receives, intermediate-frequency circuit portion is sent to Audio Signal Processing portion and vision signal handling part accordingly with this programme signal, Audio Signal Processing portion and vision signal handling part are sent to audio output part and video efferent respectively after programme signal is handled, and carry out normal play.
When the normal TV reception of user, micro-control unit (Micro Controller Unit, MCU) will judge whether that needs carry out the renewal of program channel according to user's instruction, if the user selects to carry out channel search and renewal automatically, at this moment, the MCU updating program frequency channel data device of controlling this television set inside carries out the search of channel and the renewal of channel data.
Certainly, MCU is the renewal of carrying out the search of program channel and channel data of second tuner of control updating program frequency channel data device inside.
The antenna assignment device of updating program frequency channel data device inside will be distributed to first tuner and second tuner accordingly from the high-frequency signal that antenna receives.
And first tuner and second tuner all are to be connected to MCU by iic bus independently.Wherein, the input signal of two tuners all is duplicate high-frequency signal.
Fig. 3 shows the structure of the inner MCU of television set that the embodiment of the invention provides.
Wherein, when MCU controls first tuner and carries out the broadcast of TV programme, program channel upgrades judge module and judges whether to carry out the automatic search and the renewal of program channel, if need, and control channel search update instruction receiver module receiving channels search update instruction.
The tuner control module is controlled search and the channel data renewal that second tuner carries out program channel according to the channel search update instruction.
After the tuner control module is controlled second tuner and is searched channel information, the channel searching judge module compares the channel that searches and the channel in the memory, judge whether the channel that searches exists, when the channel that searches exists, control tuner control module is proceeded search, when the channel that searches did not exist, control channel data memory module was stored to memory with this channel, and proceeds search.
In the embodiment of the invention, by setting up second tuner in television set inside, when control first tuner carries out the broadcast of TV programme, control second tuner on the backstage according to the channel search update instruction and carry out the automatic search of channel and the renewal of channel data, easy to use, solve the user and must stop the problem that TV reception carries out automatic search of channel and channel data renewal.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
