The present invention relates to an automatic search for a channel in an over-the-air wireless broadcast receiver, and more particularly, to an apparatus and method for automatically searching for a broadcast channel of a wireless receiver which reduces a search setting time by arbitrarily selecting a channel search section.

BROADCASTING is the transmission of information to be transmitted by an unspecified number of people, and there are cable broadcasting and wireless broadcasting, and the cable broadcasting, even if a reception-only equipment is prepared, a corresponding cable line between a sender and a receiver. Since it has to be hypothesized, there is a problem that it takes a lot of cost and time, but there is an advantage of the quality of the transmitted broadcast signal, the wireless broadcast, by transmitting the information wirelessly over the air, between the sender and the receiver There is no need to install a separate line in the network, and if there is only a receiving device, it has the advantage of receiving and immediately confirming the contents of broadcasting by receiving it anywhere regardless of the place, but it affects the quality of the broadcast signal transmitted by the surrounding wireless environment. .

In the above-mentioned airwave broadcasting, wireless broadcasting which receives and confirms the contents of broadcasting while freely moving is spreading much more than cable broadcasting, and the price of receiving equipment is also very cheap due to mass production.

Examples of the radio broadcasting include radio broadcasting and television broadcasting, and radio and mobile communication terminals and radio pagers are also included in the scope of wireless broadcasting. DIGITAL MULTIMEDIA BROADCASTING).

In the radio broadcasting, a radio frequency signal is divided into a predetermined band, each channel is set, and the broadcasting is performed using the frequency band assigned to each channel. As a result of the development of communication technology, the frequency band given for each channel becomes smaller. At the same time, techniques have been developed for allocating multiple channels using frequencies in the same band.

Among the above-mentioned wireless broadcasts, multimedia broadcasting or television broadcasting, which simultaneously transmits a video signal, an audio signal, and a text signal, has been further developed, and a corresponding channel has also increased. In particular, the number of broadcasting channels by satellite broadcasting or DMB broadcasting is increased. And new broadcast channels continue to increase.

As described above, in the case of an airwave radio television station broadcasting a multimedia signal or an AM, FM or digital radio airwave radio station broadcasting a voice level signal, a channel using a unique radio frequency is allocated to the radio receiver. Since a radio channel is selected and tuned, a tuner for receiving a corresponding broadcast signal is provided.

In the case of producing the receiver or receiver as described above, the tuner can be fixedly selected by the tuner, but the wireless broadcaster continues to increase, change or integrate, and at the same time, the contents of the broadcasting content to be broadcast are specialized. Since broadcasting, climbing, religion, hobby, music, cooking, and the like are broadcasted separately, a fixed allocation method for all channels is very inefficient, and the channels frequently selected by the user's taste are limited.

Therefore, a method of having a number of channels mechanically limited in an over-the-air wireless broadcasting reception device or a receiver (hereinafter referred to as a receiver) and fixedly setting a preferred broadcast to select a corresponding channel so that the preferred wireless broadcast channel is selected. Is used.

In order to set a preferred broadcast channel in the mechanical channel of the receiver as described above, all broadcast signals are tracked to search for broadcast signals, and when a broadcast signal is detected, the broadcast signal is received and outputted, and the user There is a method of setting the preferred receiving channel by the selection of.

However, due to the commercialization of satellite broadcasting and DMB broadcasting, such as voice broadcasting radio broadcasting, and the commercialization of more than 100 television broadcasting channels, the tracking of the broadcasting channel takes much time, so wireless broadcasting There is a problem that takes a long time to set a preferred channel in the receiver.

Therefore, there is a need to develop a technique for reducing the time required to select and set a preferred channel among the many broadcast channels as described above.

Hereinafter, a broadcast channel automatic search method of a wireless receiver according to the prior art will be described with reference to the accompanying drawings.

Attached to explain the prior art, Figure 1 is a general configuration diagram of a wireless broadcasting system functional configuration, Figure 2 is a flow chart of a broadcast channel automatic search method of the conventional radio receiver.

Referring to FIG. 1, a general wireless broadcasting system will be described. The wireless broadcasting receiver 10 selects, by tuning or tuning, a broadcast signal transmitted by a wireless broadcasting station 20 or a broadcasting satellite 30 by radio. Receive it.

Since the receiver 10 is wirelessly connected to the broadcasting station 20 or the broadcasting satellite 30, it does not require a separate facility, and receives the broadcasting signal anywhere in the place where the movement is free and the wireless broadcasting signal is received. Watch or listen.

Wireless broadcasting is provided worldwide by the advantage of having only the receiver 10, the advantages of simultaneously delivering the same content to a large number of users, and at the same time receiving and confirming at the same time, and delivering to a large number at a very low cost. It is a means of universal media delivery.

The radio broadcasting station 20 specializes in the contents of the content to be broadcast for the purpose of business, such as sports, hobbies, religion, education, entertainment, music, art, theater, opera, etc., the user of the receiver 10 The channel of the preferred broadcasting station is selected by tuning or tuning and the corresponding broadcast is received.

In addition, since the broadcast satellite 30 also transmits a plurality of broadcast signals, the receiver 10 should select and receive a desired broadcast channel by tuning.

As described above, the wireless broadcast channels vary greatly depending on the variety of contents. In particular, the number of channels broadcast by the broadcast satellite 30 is over 100.

The receiver 10 wirelessly receives all 100 or more channels wirelessly broadcasted by the radio broadcasting station 20 or the broadcasting satellite 30, but it is difficult for the user to store all the channels. Since all channels must be searched in order to solve the problem of time-consuming and inconvenient, selecting and recording a preferred broadcast channel to a specific channel button or dial button (hereinafter referred to as button) assigned to the receiver 10 and Since the button is selected, the broadcast contents of the preferred channel are selectively received.

Each channel button included in the receiver 10 has an automatic tracking function for searching a plurality of broadcast channels and selecting a preferred channel.

The tracking function, by sequentially tracking (TRACKING) and searching all channels currently being broadcast wirelessly, when the radio broadcast signal is received, temporarily fixed to the corresponding channel, so as to receive and output the radio broadcast signal, the user confirms and selects If so, record the frequency of the channel in the corresponding button.

Since the above process is repeatedly recorded in every button, a preferred channel is assigned to the provided button, and the button is selected in a one-touch manner to immediately receive the preferred channel.

Each channel button of the receiver 10 records and outputs the selected and recorded channel radio frequency information in the allocated memory area, but channel recording may be erased due to power failure or error, and the channel recording may be erased as described above. In this state, the tracking operation should be repeated to record and store radio frequency information of a preferred channel again.

It is difficult to memorize the preferred channel information in a state where the number of the over-the-air broadcast channels is large, and in order to record the preferred channel information on the channel button, the tracking operation must be repeated, which is time-consuming and complicated. There is a problem.

Hereinafter, with reference to the accompanying FIG. 2, a broadcast channel automatic search method for a radio receiver according to the prior art will be described.

When the radio broadcast receiver 10 wants to record and store the radio frequency of the preferred channel in the channel button (S10), all radio broadcast channels (CH) received by the receiver are sequentially tracked (TRACKING) and searched. (S20).

In step S20, it is determined whether the over-the-air radio broadcast signal is detected by the STRAKING search (S30), and when the over-the-air radio broadcast signal is received and detected in the determination (S30), the channel is temporarily fixed and received. The over-the-air broadcast signal is output (S40).

In the case of the voice level receiver 10, the broadcast signal output by wireless reception in the step S40 outputs only the sound level signal of an appropriate level through the corresponding audio unit, and the multimedia receiver 10 or the television TELEVISION. In the case of the receiver 10, an image and a text signal are output through a corresponding MONITOR and an audio level signal is output through the corresponding audio unit.

As described above, the signal of the channel output through the receiver 10 is checked and it is determined whether to select (S50).

If the current reception channel is not selected in the determination (S50), the process proceeds to the second step (S20), repeats the sequential tracking search of the channel in the following order, and selects the current reception channel in the determination (S50). In this case, since the radio frequency of the channel is recorded and stored in the memory area allocated to the corresponding channel button, it is set as the preferred reception channel (S60).

The conventional technology of the above-described configuration, for example, when the air channel radio frequency information recorded and stored in the allocated memory area of the channel button is erased or an error occurs, for example, the tracking process of more than 100 air wave broadcasting channels for the first time Since starting again, there is a time-consuming problem.
