Abstract

PURPOSE: A set top box channel searching method is provided to reduce a period of time required for a user to select a desired channel among a plurality of channels. CONSTITUTION: A user sets a search range through a key operation unit formed at a set top box when the user searches channel information stored in the set top box(S4). When the user calls the channel information using the key operation unit in order to search the channel information stored in the set top box, the channel information is displayed(S5). The user searches the displayed channel information according to the set search range(S6), and then selects a desired channel(S7). The key operation unit includes a range setting part. The search range is inputted in such a manner that the user inputs a set value corresponding to the search range through the key operation unit while pushing the rand setting part.

Description

{Method Searching channel of set top box}

The present invention relates to a channel search method of a set top box, and more particularly, to a channel search method of a set top box that enables a user to select a search range when a user searches for channel information.

In general, satellite broadcasting refers to television or radio broadcasting using a broadcasting satellite located 35,784 Km above the earth. Satellite broadcasting is intended to receive broadcasts directly to the general public, and to receive signals from space stations mounted on satellites. It is a broadcasting method of transmitting or retransmitting.

Since satellite broadcasting transmits radio waves directly from satellites to satellite antennas, the image quality is clear due to the low image quality, and high quality is possible because of multiplexing and QPSK modulation using MPEC-2. Because of this, it is possible to broadcast all over the country in an emergency without being damaged by nature or war.

On the other hand, the set-top box that can receive the satellite broadcasts GUI to allow the user to check the channel information of the received broadcast, and to adjust the function selection and settings for viewing and listening to the broadcast and the user convenience options Provides a menu screen in the form of (Graphic User Interface).

1 is a block diagram showing the configuration of a general satellite receiver.

A typical satellite receiver includes a satellite antenna 10 capable of receiving channel information transmitted from a plurality of satellites, a set top box 30 in which channel information received by the satellite antenna 10 is stored, and a set top box provided by a user. Selecting the desired channel information through the key operation unit 31 formed in the 30, the satellite selection unit 20 to select the satellite according to the, and the user can check the channel information stored in the set-top box 30 It is composed of a display unit 40 for displaying the channel information to the outside, the key operation unit 31 means a plurality of key buttons or remote controller formed on the outside of the set-top box 30.

2 is a flowchart illustrating a channel searching method of a set top box according to the related art.

In the conventional channel search method of a set-top box, first, in step 1, when a user calls channel information using the key operation unit 31, channel information corresponding thereto is displayed on the display unit 40 (S1). Reference)

In step 2, the user searches for the channel information displayed in step 1 by using a key button for performing a channel search function on the key operation unit 31 (see S2).

Herein, the key button means a channel up / down key or a page up / down key. The channel up / down key increases or decreases the channel by one unit, and the user searches for channel information. The key increases or decreases the channel by ten units and searches for the channel desired by the user.

In step 3, the user repeats the operations of step 2 to search for and select a desired channel (see S3).

However, the conventional channel search method of a set-top box has a problem that a user spends a lot of time searching for a desired channel when a user searches a plurality of channel information received from a plurality of satellites using a key manipulation unit.

The present invention has been made to solve the above-mentioned problems of the prior art, the object of which is to consume the user to search the desired channel by setting the desired search range when the user searches for channel information stored in the set-top box To reduce time.

According to a feature of the channel search method of the set-top box according to the present invention for solving the above problems, when the user searches for channel information stored in the set-top box range setting to set the search range through the key operation unit formed in the set-top box And displaying, when the user calls the channel information by using the key operation unit to retrieve the channel information stored in the set-top box, the channel information corresponding to the channel information is displayed, and when the user is displayed in the display step. A channel search step of selecting a desired channel after searching the channel information according to the search range set in the range setting step.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a block diagram showing the configuration of a satellite receiver according to the present invention.

The satellite receiver according to the present invention uses a set top box 30 in which channel information transmitted from a plurality of satellites is received and stored through a satellite antenna 10, and a user through a key manipulation unit 31 formed in the set top box 30. Selects the desired channel information, and selects the corresponding satellite so that only the channel information is received accordingly, and is formed in the key operation unit 31 so as to search a range when the user searches for the channel information. It is composed of a range setting unit 31a for enabling the setting, and a display unit 40 for displaying the channel information so that the user can search for the channel information.

Looking at the operation of the present invention configured as described above are as follows.

4 is a flowchart illustrating a channel searching method of a set-top box according to the present invention.

First, in step 1, the user sets a search range to be used when searching for the channel information by using the range setting unit 31a. (See S4.)

In step 2, when the user calls the channel information through a key operation of the key operation unit 31 to retrieve the channel information stored in the set-top box 30, the channel information corresponding thereto is displayed in the display unit 40. Is displayed (see S5).

In step 3, the channel information displayed in step 2 is searched according to the search range by using a key button related to channel information search in the key operation unit 31 (see S6).

Here, the key button means a channel up / down key or page up / down key formed in the key operation unit 31, and the channel information is obtained using the channel up / down key or page up / down key. When searching, the channel information is searched according to the search range.

In step 4, the user selects a desired channel after searching for the channel information in step 3 (see S7).

In the channel search method of the set-top box of the present invention configured as described above, when the user checks the channel information stored in the set-top box, the user can set a desired range from the plurality of channel information by setting a range to search through the key operation unit. There is an effect that the time spent to select is reduced.
