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.
In embodiments of the present invention, increase a tuner and decoder, microcontroller is when the TV programme of the frequency that control is selected the user is play, first tuner regularly the full range point is carried out signal search, first decoder is decoded to the frequency point data of locking, microcontroller compares the frequency of storing in decoded frequency that signal arranged and the memory, then new frequency is stored in the memory, avoided the user to stop current TV programme of watching, initiatively user time has been saved in the operation of searching platform.
The platform checkout gear of searching that the embodiment of the invention provides is built in television set, when providing the pairing TV programme of frequency of controls playing active user selection for the user, searches for the full range point automatically, and newly-increased frequency is stored in memory, makes things convenient for the user.
Fig. 1 shows the structured flowchart of searching the platform checkout gear that the embodiment of the invention provides, for convenience of explanation, only provided the part relevant among the figure with the embodiment of the invention, search the platform checkout gear and comprise TV programme broadcast unit, the microcontroller that is connected with the TV programme broadcast unit, the memory that is connected with microcontroller, first tuner and first decoder, wherein:
In embodiments of the present invention, second tuner locking user selects the pairing frequency of TV programme; Second decoder is connected with second tuner, and the frequency point data of second tuner locking is decoded, and obtains television programme data; Microcontroller is connected with second decoder, and the television programme data of obtaining behind second decoder decode is play in control.
In embodiments of the present invention, first tuner is connected with microcontroller, regularly the full range point is carried out signal search, and according to carrying out locking frequency point to the order of high frequency points from low frequency; First decoder is connected with microcontroller with first tuner, the frequency point data of first tuner locking is decoded, and judge whether the frequency of first tuner locking has signal; Microcontroller is connected with first decoder, memory, will have the frequency of signal and the frequency of memory stores to compare behind first decoder decode, and new frequency is stored in the memory.
In embodiments of the present invention, judge that it is to judge whether current frequency has the output of audio or video data that current frequency has no signal; When judging that current frequency has signal, the pairing frequency point information of the TV programme of storing in current frequency and the memory is compared, if the frequency of locking has storage in memory, represent that then the pairing program of current frequency is on user's TV guide, if not then represent the TV programme of the pairing program of current frequency for not having on user's the TV guide, need this frequency is stored in the memory, increase new TV programme.
In embodiments of the present invention, when microcontroller is stored in new frequency in the memory, the prompting device that is connected with 8-digit microcontroller is controlled on the television screen window menu mode and points out the user that newly-increased channel information is arranged, in this embodiment, also can be by increasing the mode of hardware device, realize voice suggestion, but not in order to restriction the present invention.
In embodiments of the present invention, first tuner is according to carrying out locking frequency point from low frequency to the order of high frequency points, should low frequency be 45.5MHz, high frequency points is 865.5MHz, promptly the locking frequency of first tuner is from 45.5MHz to 865.5MHz, with the normal 8MHz of midfeather is that example describes, thus the locking order of tuner be 45.5MHZ, 53.5MHz, 61.5MHz ..., 865.5MHz, but not in order to restriction the present invention.
In embodiments of the present invention, when first tuner and first decoder stop channel detection work, the pairing frequency of TV programme by locking user selection, mode with picture-in-picture is play new TV programme on the tv programme picture that the TV programme broadcast unit is play, realize the two-way TV programme, wherein, the voice data of the TV programme of the frequency correspondence of first tuner locking is exported by headset mode.
As a specific embodiment of the present invention, Fig. 2 shows the realization flow of searching the platform detection method, and its detailed step is as follows:
In step S101, initial frequency is set, first tuner locks initial frequency.
In step S102, in the TV programme that TV programme broadcast unit broadcast user has selected, first decoder carries out data decode to the frequency of this first tuner locking.
In step S103, first decoder judges whether the current frequency of decoding has signal, is execution in step S104 then, otherwise execution in step S105.
In embodiments of the present invention, frequency to locking is decoded, thereby judges whether this frequency has signal, judges promptly whether this frequency has television programme data stream to transmit, be to represent that then current frequency has corresponding television programme data stream to transmit, otherwise represent that current frequency is for empty.
In step S104, microcontroller compares the frequency of storing in this frequency and the memory, judges whether decoded frequency is stored to be in the memory, is execution in step S105 then, otherwise execution in step S106.
In embodiments of the present invention, when judging that current frequency has signal, the pairing frequency point information of the TV programme of storing in current frequency and the memory is compared, if the frequency of locking has storage in memory, represent that then the pairing program of current frequency is on user's TV guide, if not then represent the TV programme of the pairing program of current frequency for not having on user's the TV guide, need this frequency is stored in the memory, increase new TV programme.
In step S105, first tuner continues next frequency of locking, and returns execution in step S102.
In step S106, microprocessor controls stores this frequency in the memory into, and prompting device prompting user has new-programme information.
In embodiments of the present invention, when the frequency of first tuner locking is higher than 865.5MHz, stop to search platform.
In embodiments of the present invention, increase a tuner and decoder, microcontroller is when the TV programme of the frequency that control is selected the user is play, first tuner regularly the full range point is carried out signal search, first decoder is decoded to the frequency point data of locking, microcontroller compares the frequency of storing in decoded frequency that signal arranged and the memory, then new frequency is stored in the memory, avoided the user to stop current TV programme of watching, the initiatively operation of searching platform, saved user time,, also make things convenient for the user to check newly-increased TV programme simultaneously.
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.
