How to Display Notes on a Satellite Broadcast Receiver

The present invention relates to a satellite broadcasting receiver, and more particularly, to a memo display method of a satellite broadcasting receiver configured to display a memo recorded by a user on a monitor at a predetermined time set by the user.

Satellite broadcasting is a broadcasting system that can receive broadcast signals sent from ground stations (broadcasting earth stations) using a satellite that floats on a stationary orbit about 36,000 km above the equator, and can receive them directly from the satellite receiving antenna in each home. Compared to terrestrial or cable broadcasting system, the broadcasting system has greatly expanded the information selection range.

The satellite broadcast receiver used for the satellite broadcast receives the bit stream provided from the satellite, processes the broadcast signal of the selected channel, and then provides it to a display device (for example, a TV).

In this case, the bit stream provided from the satellite includes various information such as broadcast signals (video data and audio data), event information table (EIT), and time data table (TDT) for each channel.

The satellite broadcasting receiver used for the satellite broadcasting receives the bit stream provided from the satellite, processes the broadcast signal of the selected channel, and then provides the signal to a display device (for example, TV) to display on the screen. The receiver is provided with various menu screens or guide screens for providing the above-mentioned various information and additional functions.

However, in the conventional satellite broadcasting receiver, the memo setting / display function is not provided by the user, so that when the viewer is immersed in watching the broadcast program, he or she forgets to do something or thinks about other things to do. There were problems that could not be done.

Accordingly, the present invention has been made in view of the above-described problems, and when the user sets a predetermined memo and a time for displaying the memo, the user records the current time during reception of the satellite broadcast and records the user at the time set by the user. The present invention provides a memo display method of a satellite broadcasting receiver configured to display a memo on a screen.

The generated key signal is provided to the system controller 200.

The system controller 200 controls the overall satellite broadcast receiver in response to a key signal provided from the key input unit 100 and a signal provided by each component constituting the satellite broadcast receiver, and in particular, the key input unit 100. When a memo key signal is provided from the control unit, the OSD processing unit 700 is controlled to display a memo screen previously stored in the storage unit 400, and information on memo and memo display time provided as a key signal from the key input unit 100 is displayed. Store in the storage unit 400. In addition, the memo display time set by the user is compared with the information on the current time provided from the tuner and demodulator 130, and if the comparison time matches the current time and the memo display time, the memo stored in the storage unit 400 The OSD processing unit 700 is controlled to withdraw information about and display the extracted memo information on a preset memo screen.

The tuner and demodulator 300 transmits a broadcast signal received through a broadcast signal receiver (i.e., a satellite reception antenna), not shown, to a broadcast channel selected by a user based on a tuning control signal provided from the system controller 200. And converts the tuned broadcast channel signal into an intermediate frequency, and then demodulates the converted intermediate frequency into a transport stream through a process such as demodulation and error correction, and converts the demodulated transport stream into a next stage MPEG decoder ( 150).

In addition, the tuner and demodulator 130 extracts TDT (Time Date Table) data included in the bit stream provided from the satellite, and provides the extracted TDT data to the system controller 200. In this case, the TDT data may include information on the current time.

The storage unit 400 previously stores information on a memo screen for providing to a user and a key code corresponding to a key signal, and at a memo screen display time set to display memo information recorded by the user and the memo information. Information about this is stored.

The MPEG decoder 500, based on the system controller 300, considers the spatial and spatial correlation of the compressed coded video signal of the tuned satellite broadcast channel provided from the tuner and the demodulator 130, for example, the video signal. The decoded video signal is restored to the original signal before encoding by using a decoding technique such as variable length decoding, inverse DCT, inverse quantization, and motion compensation, and provides the reconstructed digital video signal to the video encoder 600.

The video encoder 600 converts the digital video signal provided from the MPEG decoder 500 into an NTSC or PAL analog video signal, and provides the converted signal to the image synthesizer 180.

The OSD processor 700 OSD processes the information on the memo guide screen and the information on the memo screen provided from the system controller 200, and outputs an OSD signal corresponding to the information on the memo guide screen and the information on the memo screen. The image synthesizer 800 is provided.

If the OSD signal is not provided from the OSD processing unit 700, the image synthesizing unit 800 bypasses the analog satellite broadcasting signal provided from the video encoder 600 to the display unit 900, and displays the OSD screen from the OSD processing unit 700. Data is provided, and the provided OSD signal and the analog satellite broadcast signal provided from the video encoder 600 are mixed in a predetermined format, and the mixed image data is provided to the display 900.

The display unit 900 includes a monitor (not shown) and the like, and displays the image data output from the image synthesizing unit 800 on a monitor.

Hereinafter, a process of implementing a memo display method according to an exemplary embodiment of the present invention using a satellite broadcast receiver including a component that performs the above-described function will be described in detail.

First, a broadcast signal for a specific channel set by a user is received by the tuner and demodulator 300, and the received broadcast signal is transmitted to the MPEG decoder 500, the video encoder 600, and the image synthesizer 800. The user inputs the key input unit 100 to memoize predetermined contents such as an appointment time, a place, etc. during the normal viewing mode displayed on the display 900 as a predetermined image through a series of signal processing processes. When the memo key included in the key is operated, the key input unit 100 generates a memo key signal corresponding to the memo key, and provides the generated memo key signal to the system controller 200. (S20)

In operation S 20, the system controller 200 receiving the memo key signal from the key input unit 100 searches for and retrieves information on the memo screen previously stored in the storage unit 400, and retrieves the information on the memo screen. While providing the OSD processing unit 700, the OSD processing unit 700 will be driven to control the OSD processing of the information on the memo screen, and the OSD processing unit 700 may be controlled by the system control unit 200. The information on the memo screen provided at 200 is reconstructed as an OSD signal and provided to the image synthesizing unit 800.

Accordingly, the image synthesizing unit 800 may provide a broadcast signal for a specific channel provided from the video encoder 600 and an OSD signal for a memo screen provided by the OSD processing unit 700 according to the execution of the normal viewing mode in step S 10. By synthesizing and providing to the display unit 900, the memo screen will be displayed in a predetermined section of the screen where an image for a specific channel is displayed. In this case, the memo screen may include a time setting field for setting the memo display time, a memo recording field for recording the memo, and a cursor for displaying the time setting and a position for recording the memo.

In step S30, in order to set the memo display time and record the memo contents, when the user operates the direction key, the numeric key and the character key provided in the key input unit 100, the key input unit 100 is adapted to the user's key operation. Corresponding direction key signals, numeric key signals, and character key signals are generated, and the generated key signals are sequentially provided to the system controller 200 (S40).

In operation S40, the system controller 200, which receives various key signals from the key input unit 100, retrieves and retrieves direction information, numeric information, and character information corresponding to each key signal from the storage unit 400. While providing the extracted information to the OSD processing unit 700, the OSD processing unit 700 will be controlled to OSD process the provided information.

By the control of the system controller 200, the direction information, the numeric information, and the character information provided to the OSD processing unit 700 are displayed in the same procedure as step S30, and the memo display time set by the user is displayed in the time setting column of the memo screen. In the memo record field, a memo recorded by the user will be displayed. In this case, the user may record, delete, or modify the memo display time and the memo content while checking the letters and numbers displayed on the memo screen.

In addition, the system controller 200, which receives various key signals from the key input unit 100 in operation S 40, stores the combination of a series of key signals provided from the key input unit 100 in the storage unit 400. In this case, the combination of the key signals will be information on the memo display time set by the user and the memo recorded by the user (S 50).

When the user who has completed the setting of the memo display time and the recording of the memo content by the operation of step S50 operates the memo completion key included in the key input unit 100, the key input unit 100 responds to the user's key operation. A memo completion key signal is generated and the generated memo completion key signal is provided to the system controller 200. (S60)

In operation S 60, the system controller 200 which receives the memo completion key signal from the key input unit 100 controls to stop driving the OSD processing unit 700, and the OSD processing unit 700 is controlled by the system control unit 200. By stopping the driving, the image synthesizing unit 800 may bypass only the broadcast signal for a specific channel provided by the video encoder 600. That is, the display 900 switches to the normal viewing mode in which only the image corresponding to the broadcast signal is displayed.

Meanwhile, the system controller 200 receives a time date table (TDT) signal from the tuner and demodulator 130 during the execution of the normal viewing mode in which the step S70 is switched, and checks the current time Tc (S80). In operation S50, the checked current time Tc and the memo display time Td stored in the storage unit 400 are determined to match. That is, it is determined whether the current time Tc reaches the memo display time Td set by the user (S90).

As a result of the determination in step S90, when the current time Tc reaches the memo display time Td set by the user, the system controller 200 may provide information on the memo contents stored in the storage unit 400 in step S50. Search and withdraw the information, and provide the OSD processing unit 700 with information on the extracted memo contents, and control the OSD processing unit 700 to OSD process the information on the memo contents. ) Reconstructs the information on the memo content provided by the system controller 200 into an OSD signal and provides the image synthesizer 800 with the control of the system controller 200.

Accordingly, the image synthesizing unit 800 may provide a broadcast signal for a specific channel provided from the video encoder 600 and an OSD signal for memo contents provided from the OSD processing unit 700 according to the execution of the normal viewing mode in step S 70. By synthesizing the information to the display unit 900, the memo recorded in step S 50 will be displayed in a predetermined section of the screen on which an image of a specific channel is displayed.

When the user who checks the memo in step S 100 operates the memo confirmation key provided in the key input unit 100, the key input unit 100 generates a memo confirmation key signal corresponding to the user's key operation to generate the system control unit 200. (S 110)

In operation S 110, the system controller 200 which receives the memo confirmation key signal from the key input unit 100 controls to stop the operation of the OSD processing unit 700, and the OSD processing unit 700 is controlled by the system control unit 200. By stopping the driving, the image synthesizing unit 800 may bypass only the broadcast signal for a specific channel provided by the video encoder 600. That is, the display 900 switches to the normal viewing mode in which only the image corresponding to the broadcast signal is displayed.

As described above, according to the present invention, the user can enhance the usability of the satellite broadcast receiver by adding a memo function to the satellite broadcast receiver to display the user's memo at a predetermined time while the user is watching the satellite broadcast program. It has an effect.
