When the time information provided from the transmitter matches the set time, the user automatically switches to the corresponding channel to watch the program reserved by the user.

However, such a general reservation method of a satellite receiver is a simple reservation method in which a reservation mode is performed only by a time and a channel set by a user, and it is impossible to reserve a title of a specific program or a program of the same genre.

Accordingly, the present invention has been proposed to solve various problems occurring in the conventional satellite broadcasting receiver as described above.

An object of the present invention is to enable the program reservation by the "title" and satellite broadcasting to provide the convenience of viewing to the user by automatically displaying a message on the channel switching or alarm transmission or screen according to the user's mode selection when viewing the reservation It is to provide a program reservation method of the receiver.

The method of the present invention for achieving this object,

A first step of displaying program guide information received after entering a program reservation mode when a program is reserved for each title and storing a program title selected by a user in a memory;

A second step of searching for the same program by comparing the stored program title with the received program title after storing the title, and storing the searched program broadcasting time and channel in the memory;

When the stored program airing time is reached, it is characterized in that it comprises a third step of sending an alarm or switching a channel to a reserved channel according to the user's mode selection, or displaying data related to the airing of the reserved program on the monitor.

A demodulator 2, a channel decoder 3 for correcting errors and errors in the channel data obtained from the tuner and the QPSK demodulator 2, and a descrambler for descrambling the encrypted data obtained from the channel decoder 3 ( 4) an MPEG decoder 5 which decodes the descrambled broadcast data into original data and separates and outputs the audio and video signals, an alarm unit 6 for transmitting an alarm, and the MPEG decoder 5 Encoder (7) for encoding a signal obtained by the sig- nal according to the color format, and audio and video encoded by the encoder (7) to a speaker and a monitor. And a matrix unit (8), a central processing unit (9) for performing overall control of the satellite broadcasting reception and making reservations in the reservation mode, and a program for operating the central processing unit (9). A memory 10, a nonvolatile RAM 11 for storing a content nibble corresponding to a title or genre reserved in the reservation mode and storing a broadcast time and a channel of the program, an interface with a smart card or an interface of a user or It consists of an interface unit 12 for interfacing with a personal computer and a modem 13 for data communication via a PSTN.

With reference to the satellite broadcasting receiver to which the present invention configured as described above is applied, a detailed description will be made based on FIG. 2 and FIG. 3 attached to the title and genre program reservation method according to the present invention.

First, in general TV viewing, a broadcast signal processed by the high frequency processor 1 is tuned and QPSK demodulated by a tuner and a QPSK demodulator 2, and an error and error of data are corrected by the channel decoder 3, followed by an MPEG decoder. (5) is passed.

Then, descrambling of the data encrypted by the descrambler 4 is performed, the compressed MPEG stream data is expanded to the original data, and the program guide data is transmitted to the central processing unit 9, and audio and video are transmitted to the encoder ( After encoding in accordance with the color format (NTSC or PAM / SECAM) in 7), audio is transmitted to the speaker and video is transmitted to the monitor in the switch and matrix section 8.

In addition, the central processing unit 9 stores the transferred program guide data in the memory 10, and interfaces with an external video device through the interface unit 12 or the modem 13.

Next, the reservation operation will be described.

First, in the program reservation method for each title as shown in FIG. 2, when entering the program reservation mode (ST1), the central processing unit 9 displays the received program guide information on the monitor (ST2), When the program is guided as described above, the user selects a desired program title (ST3).

Here, the title can be easily selected by operating a key provided in the remote controller or the main body.

When the title is selected, the CPU 9 stores the title selected by the user in the nonvolatile RAM 11 (ST4). Here, a plurality of titles to be reserved can be selected.

After storing the title selected by the user, the reserved program title is compared with the string of the event name field in the event guide table in which the program guide information is transmitted from the transmitter (ST5), and the program corresponding to the same title is broadcasted. The time and the channel are stored in the nonvolatile RAM 11 (ST6).

In addition, the program compares the broadcast time of the reserved program with the time data table value, which is the current time information sent from the transmitter (ST7), and operates in the designated mode when the scheduled time arrives (ST8 ~ ST10).

Here, the mode designation is made by the user at the time of program reservation, and the mode is the alarm mode that sends an alarm when the scheduled time arrives and the automatic channel switching mode and reservation that automatically switches the channel to the program broadcast channel when the scheduled time comes. When the time comes, there is a screen display mode that displays data about the program on the on-screen display (OSD).

Next, the reservation method for each genre is shown in FIG.

That is, when entering the program reservation mode (ST11), the central processing unit 9 displays the program on the monitor (ST12), and when the program is guided in this way, the user selects the desired program genre (ST13).

Here, selection of the genre can be easily performed by operating keys provided in the remote controller or the main body.

When a genre is selected, the CPU 9 stores the genre delimiter called Content Nibble, which is regulated by the transmitter and the receiver corresponding to the genre, in the nonvolatile RAM 11 (ST14).

After storing the content nibble of the genre selected by the user, the content nibble value indicating the reserved program genre is compared with the content nibble value of the event in the event guide table containing the program guide information sent from the transmitter (ST15). The airtime and channel of the program corresponding to the same content nibble are stored in the nonvolatile RAM 11 (ST16).

Then, it compares the airtime of the reserved program with the time data table value, which is the current time information sent from the transmitter (ST17), and operates in the designated mode when the scheduled time arrives (ST18 to ST20).

Here, the mode designation is made by the user when the program is scheduled, and the mode is the alarm mode that sends an alarm when the scheduled time arrives, and the automatic channel switching mode that automatically switches the channel to the program broadcast channel when the scheduled time comes. When the time comes, there is a screen display mode that displays data about the program on the on-screen display (OSD).

According to the present invention "program reservation method of the satellite broadcast receiver" described above, if you reserve the title of a continuous program such as a daily soap opera only once, there is a convenient advantage that you can always watch in the airing time of the program.

In addition, since the program can be viewed by the title, there is an effect that can maximize the program selectivity of the user.

In addition, there is an effect that the user can select and watch a genre reservation once without having to confirm the desired genre by using the program guide information.

In addition, since the mode for informing the reservation time is various, such as an alarm mode, an automatic channel switching mode, and a screen display mode, there is an advantage in that it can be more customized to a user's preference.
