Channel Information Storing and Sharing Methode of Broadcasting Reciever}

The present invention relates to a method of storing and sharing channel information of a broadcast receiver. More particularly, the present invention relates to a method of storing and sharing channel information of a broadcast receiver by mounting a memory stick in which the channel information is input / stored to the broadcast receiver, and using the channel information input / stored in the memory stick. The present invention relates to a method of storing and sharing channel information of a broadcasting receiver for viewing.

In general, the number of broadcast channels received by a digital broadcast receiver continues to increase with the development of a broadcast environment. Accordingly, broadcast program services are also greatly developed in terms of quantity and quality. In the case of the previous analog broadcasts, the number of channels has reached dozens, but in the case of digital broadcasts, four to eight channels can be set in the frequency band of one analog broadcast channel, thus having hundreds of channels. The desired broadcast content is provided to the viewers of the hierarchies having various tastes according to the region and the region.

It is not easy to find the type of broadcast desired by the user every time among the numerous channels having such various contents. Even if the user finds the broadcasting channels according to the user's preference, it is difficult to select only the channels that the user has previously watched among the numerous channels for later viewing.

In order to solve this problem, information about a channel that a user prefers to watch is stored in a memory embedded in a broadcast receiver, and the channel information stored in the memory is loaded and used for later viewing. You can watch your favorite channels without searching.

However, this method of storing channel information is inconvenient to find a desired broadcast by searching a channel again when watching a broadcast program using a broadcast receiver other than a broadcast receiver storing information of a channel preferred by a user.

For example, if a user has stored 3, 5, 33, 35, 69, 79, 86, and 90 channels in memory in a broadcast receiver in his home, the user can later use the broadcast receiver to broadcast. When watching a program, the channel setting information stored in the memory can be loaded and used so that the user can easily watch the program by searching for the desired channel without having to search for the channel again. In this case, the channel 3, 5, 33, 35, 69, 79, 86, 90 must be searched again so that the user can watch the desired broadcast program. In addition, when the number of channels desired by such a user is large, a lot of time is required for channel searching, which is inconvenient. In addition, when applying the channel setting information of the other user to his broadcast receiver, there was an inconvenience to search and store the channel one by one.

The present invention has been invented to solve such a problem, by storing information about a preferred channel in a memory stick, and mounting the memory stick to a broadcast receiver to search for a channel to watch a broadcast program, the preferred channel for each viewing There is no need to search for.

Another object of the present invention is to enable other users to share channel setting information of one user.

According to the method of storing and sharing channel information of the broadcast receiver of the present invention having the above object, when storing the channel setting information of the user in the memory stick and watching the broadcast program again in the future, the channel setting information stored in the memory stick is simply loaded by loading the channel information. To watch a broadcast program, use the channel setting information stored in the memory stick to watch the desired channel without having to search for the desired channel again, even if the broadcasting receiver is changed, and to store the channel setting information of other users. You can save it on a stick and share it.

A method of storing and sharing channel information of a broadcast receiver according to the present invention includes: a first step of determining whether channel setting information exists in a main area of a memory stick when a memory stick is connected; And

In the first step, if present, the channel setting information of the internal memory is moved to the buffer area of the memory stick, and the channel setting information of the main area of the memory stick is copied to the internal memory. .

The additional information stored in the memory stick 20 and separated and processed by the demultiplexer unit 12 is stored in the internal memory unit 18.

In addition, the key input unit 19 is provided with keys for setting the functions of the above-described control unit 17, so that the user can set the above-described functions using the keys.

Hereinafter, a preferred embodiment of a method of storing and sharing channel information of a broadcast receiver according to the present invention will be described in detail with reference to FIG. 2.

First, it is determined whether the memory stick 20 is connected (21).

As a result of the determination 21, when the memory stick is connected, it is determined whether the channel setting information exists in the main region 320 of the memory stick 20 (22).

As a result of the determination 22, when the channel setting information does not exist, the broadcast program is watched by the channel setting information stored in the internal memory 18 of the broadcast receiver. On the other hand, when the channel setting information exists, the internal memory Channel setting information stored in (18) is moved to and stored in the buffer area 310 of the memory stick 20 (23).

In this step, the channel setting information stored in the internal memory 18 is moved to the buffer area 310 and stored, and then the channel setting information stored in the main area 320 of the memory stick 20 is stored in the broadcast receiver. Copied and stored in the internal memory 18 (24).

Thereafter, the user selects a channel by using the up / down key of the key input unit 19 as the channel setting information stored in the internal memory 18 (25), and selects a channel which is not set in the channel setting information. In the case of inputting a predetermined channel number to the key input unit 19, it is selected (26). When the selected channel is added to the channel setting information of the internal memory 18, an additional command is added to the key input unit 19 to add the channel, and when the unwanted channel is deleted from the channel set in the channel setting information. The channel is deleted by inputting a delete command to the key input unit 19 (27).

In the above step, when the channel setting information is changed due to the addition / deletion of a channel, it is determined whether the changed channel setting information is stored in the main area 320 of the memory stick 20 (28).

As a result of the determination 28, in the case of not storing the channel setting information, it is determined whether a return command has been input (29).

On the other hand, in the case where the determination result 28 stores the channel setting information, it is determined whether or not the memory stick 20 exists (30).

Referring to the twenty-ninth step of determining whether or not the return command has been given, first, if the return command is not issued, the broadcast program is continuously watched with the channel setting information stored in the internal memory 20. It is determined whether or not the stick 20 exists (31).

The determination result 31 determines whether to turn off the power when the memory stick does not exist (36). Meanwhile, when the determination result 31 and the memory stick 20 exist, the memory stick ( The channel setting information stored in the buffer area 310 of 20 is moved to the internal memory 18 and then overwritten and stored in the channel setting information existing in the internal memory 18 (33).

In this step, it is determined whether to turn off the power after storing the channel setting information in the internal memory 18 (36).

On the other hand, when the process after step 30 is described, it is determined whether to turn off the power when the memory stick 30 does not exist, and if present, the channel setting information stored in the internal memory 18 is stored in the memory. Copied and stored in the main area 320 of the stick 20 (32).

Subsequently, it is determined whether or not to delete the channel setting information stored in the main area 320. If not, it is determined whether to turn off the power of the broadcast receiver (36). After the channel setting information is deleted (35), it is determined whether to turn off the power (36).

As a result of the determination 36, when the power is turned off, the process ends. If not, the process returns to the twenty-first step.

For example, a method of storing and sharing channel information of the broadcast receiver may be connected to the broadcast receiver without channel setting information in the memory stick 20. In this case, when the memory stick 20 is connected, the channel setting information stored in the internal memory 18 is applied to the broadcast receiver. Thereafter, the channel is selected by the channel setting information stored in the internal memory 18. The channel is limited to the channel set in the selected channel setting information. When the channel is deleted, the key input unit 19 deletes the channel according to the delete command. In addition, when a channel is added to the channel setting information, a channel key of the key input unit 19 is used to select and add a channel not set in the channel setting information, and then add the channel according to the selection.

After the above step, it is determined whether to store the channel setting information stored in the internal memory 18 in the main area 320 of the memory stick 20, and the channel setting information is stored in the main area 320. In the case of copying and storing the channel setting information, the channel setting information is simultaneously present in the main region 320 and the internal memory 18 of the memory stick 20. In this process, the channel setting information of the internal memory 18 may be stored and shared in the memory stick 20.

On the other hand, when the channel setting information is present in the memory stick 20 and connected to the broadcast receiver, the channel setting information stored in the internal memory 18 is first stored in the buffer area 310 of the memory stick 20. Move to save. In this case, the channel setting information does not exist in the internal memory 18 because it is moved and stored.

Thereafter, the channel setting information stored in the main area 320 of the memory stick 20 is copied and stored in the internal memory 18. In this case, the same channel setting information exists in the main area 320 and the internal memory 18 because the data is copied and stored. Subsequently, the channel is selected and the channel setting information is deleted / added according to the selection (a description overlapping with the description in the above-described example will be omitted).

In the above step, when the deleted / added changed channel setting information is to be stored in the memory stick 20, first, the memory stick 20 is stored in the internal memory 18 when it is connected. The channel setting information is copied to the main area 320 of the memory stick 20 and overwritten. Therefore, the channel setting information stored in the internal memory 18 and the main area 320 becomes the same. Thereafter, it is determined whether or not to delete the channel setting information stored in the main area 320 and deleted according to the selection.

In case of returning to the initial state without storing the channel setting information of the internal memory 18 in the main area 320 of the memory stick 20, after determining whether the memory stick 20 is present, the memory is present if it exists. The channel setting information stored in the buffer area 310 of the stick 20 is moved to the internal memory 18 and then overwritten and stored. In this case, since the channel setting information does not exist in the buffer area 310 and the channel setting information of the main area 320 of the memory stick 20 does not change, the state before the memory stick 20 is connected. Is restored. Through this process, the channel setting information existing in the internal memory 18 may be stored in the memory stick 20, and the channel setting information existing in the memory stick 20 may be stored in the internal memory 18 or may be stored in the memory. After watching the broadcast program with the channel setting information stored in the stick 20, the setting may be returned to the initial state. After that, while carrying the memory stick 20 separated from the broadcast receiver and carrying it, the memory stick 20 is mounted on another broadcast receiver to watch a broadcast program with channel setting information desired by the user.

On the other hand, while the invention has been shown and described with respect to certain preferred embodiments, the invention will be variously modified and changed without departing from the spirit or field of the invention provided by the claims below It will be readily apparent to one of ordinary skill in the art.

The method for storing and sharing channel information of the broadcast receiver according to the present invention described above in detail, selects and stores only the channels to be viewed and stored in a memory stick, thereby facilitating viewing of a preferred channel without having to search for the channel again. By using a memory stick that is easy to attach / detach and carry, it is easy to search for a preferred channel even when the broadcasting receiver is changed, and also to share channel information among users.
