Abstract

The present invention relates to a speech recognition TV, and the channel selection method in the conventional speech recognition TV that is generally used uses a DDD number, which means that even if the area of the same DDD number is different in the channel number of each broadcasting station depending on the region. In some cases, the channel number assignment of the original interregional broadcasting station does not generally match the region of the DDD number, and the selection method of the interregional broadcasting station channel number by the DDD number is very redundant, and when the DDD number is changed or added, There is no countermeasure.

Accordingly, the present invention was conceived to allow a user to directly input a channel number for each broadcasting station by using a channel number input step in view of the deficiencies according to the conventional circuit as described above. If the channel numbers of the broadcasting stations are different, the channel numbers of the broadcasting stations can be freely input.

The present invention relates to a voice recognition TV, and more particularly, to an interregion broadcast station channel number selection circuit of a voice recognition TV, which is suitable for supplementing the shortcomings of the conventional method of selecting an interregional broadcast station channel number by a DDD number.

In general, the voice recognition TV includes a channel change function by a broadcaster name. However, since the channel number of each broadcasting station varies from region to region, the conventional voice recognition scheme uses a DDD number to solve this problem.

That is, in the mode of inputting the DDD number, when the DDD number of the area where the user lives is input by the remote controller, the recognition TV selects and stores the channel number of each broadcasting station. After that, the user sets the channel number simply by pronouncing “MBC” in the recognition mode. For example, if the area used was Seoul, it would be set to channel 11.

However, this method has a lot of problems. Even in the region of the same DDD number, the channel number of each broadcasting station is different depending on the region. For example, in the case of Europe and America (DDD = 0564), MBC = In the 11 or border zone, the MBC channel number of the neighboring area is used instead of MBC 11.

The allocation of channel number of the original inter-regional broadcasting station does not generally match with the DDD number area, and the selection method of inter-regional broadcasting station channel number by DDD number is very redundant, and countermeasures are applied when the DDD number is changed or added. There will be no.

Accordingly, the present invention allows the user to directly input the channel number for each broadcasting station by using the channel number input step in view of the deficiencies according to the conventional circuit as described above, and the channel of each broadcasting station depending on the area even if the DDD number area is used. If the numbers are different, the channel number of each broadcasting station can be freely input.

1 is a circuit diagram of the present invention, as shown therein, a wireless transceiver unit 1,3 for wirelessly transmitting and receiving a user's voice, and an A / D converter 2 for converting an analog voice signal into digital data. A program memory 5 and a data memory 6 for storing program and temporal data, a voice memory 8 for storing modulated ADPCM data of analog voice, and ADPCM data from the voice memory 8; A voice synthesizer 7 for reconstructing and reconstructing it into PCM data and reproducing it as an analog signal, a TV interface unit 9 for checking or controlling the TV, and the wireless receiver 1 and A / D conversion Analyzes the voice coming from the unit (2), extracts the feature, and stores it in the data memory (6), while comparing the input voice with the registered voice feature group in the data memory (6). A is chosen and configured in a digital signal processing unit 4 and a remote control 11 for the input of a channel change or the registration / recognition mode for controlling the functions of the TV corresponding thereto.

Referring to the operation and effect of the circuit of the present invention configured as described above in detail as follows.

First, the process of inputting the number of channels according to the present invention will be described based on the flowchart of FIG. 2, 1) the user first presses the channel input key of the remote controller 11 to enter the channel input step. 2) At this time, the message “Enter the channel number of KBS1” on TV is synthesized. The user inputs a 2-digit channel number using the numeric keys of the remote controller 11 (for example, “09” in Seoul).

If the input channel number is out of the range of 02 ~ 83, repeat the process of 2) above. If the input channel number is within the range of 02 ~ 83, input the channel number to CHNO [KBS1] of the data memory. Save it.

Then, the above steps 2) and 3) are repeated except that KBS2, MBC, SBS, and EBS are replaced in the order of KBS1.

Meanwhile, a process of selecting a broadcasting station in the recognition mode will be described based on the flowchart of FIG. 3.

1) The user sets the TV to the recognition mode by pressing the [Registration Recognition] key of the remote controller 11.

2) Pick up a broadcasting station with the radio transmitter 2, for example, select "KBS1" and pronounce it "KBS1".

3) The TV performs recognition of the input broadcast station name, and the TV reads the channel number of the selected broadcast station from the data memory 6 and transmits it to the TV through the TV interface unit 9.

As described above, the present invention can freely input the channel number of each broadcasting station even if the channel number of each broadcasting station is different according to the region even in the region of DDD number.

Claims (1)

Wireless transceivers 1 and 3 for wirelessly transmitting and receiving user voices, A / D converters 2 for converting analog voice signals into digital data, and program memory 5 for storing programs and temporary data. And a data memory 6, a voice memory 8 for storing modulated ADPCM data of analog voice, and reading ADPCM data from the voice memory 8, restoring it to PCM data and reproducing it as an analog signal. The voice synthesizer 7, the TV interface unit 9 that checks the control and status of the TV, and the voices received from the wireless receiver 1 and the A / D converter 2 are analyzed and extracted.
