The present invention relates to a digital broadcast receiver equipped with an HDD, and more particularly, to a memo editing method using a time shift in a digital broadcast receiver equipped with an HDD.

In general, a digital broadcast receiver is a device for receiving and displaying various TV image data of a multi-channel transmitted through a network or a satellite, and an MPEG-2 transmitted through a network or a satellite. By receiving the digital broadcast data compressed by the method, the compressed data is decompressed, the encoded data is decoded and converted into a standard NTSC signal to be displayed on a TV receiver.

That is, the digital broadcast receiver receives a bit-stream type digital broadcast signal transmitted by a broadcasting station and broadcasts a channel selected from the broadcast signals received by transport demux. It is configured to extract the signal, decode the extracted broadcast signal in a moving picture experts group (MPEG) -2 scheme, and display the extracted broadcast signal.

On the other hand, in the digital broadcasting receiver as described above, if the user leaves the seat for a while while watching TV, the user can save the seat by using the PVR (Personal Video Recorder) function to prevent the user from missing part of the broadcast. It also provides a time shift function that allows you to check again what you missed while you were away.

However, in the conventional time shift function as described above, the broadcasting signal received from the selected channel is recorded for a predetermined time by allocating a predetermined area to the HDD, and the memo content associated with the broadcasting signal at any time of the broadcasting signal that the user is watching is recorded. If you want to insert a letter after the recording is complete, there was an inconvenience to go through a separate editing procedure.

Accordingly, an object of the present invention is to provide a simple memo editing method using a time shift in a digital broadcast receiver equipped with an HDD.

The present invention for achieving the above object is a method of editing a memo using a time shift in a digital broadcast receiver equipped with a HDD, (a) when the power is turned on to tune to the channel set by the user to display a broadcast signal received from the selected channel (B) time-shift recording the broadcast signal using a time shift function, (c) receiving a memo insertion request at an arbitrary position of the time-shifted broadcast signal, and (d) Inserting memo contents input according to the memo insertion request at the insertion position of the broadcast signal; and (e) after inserting the memo, return to the current broadcast time of the corresponding channel through a time shift function to provide a broadcast signal. And displaying the display.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the preferred embodiment according to the present invention.

1 is a block diagram of a digital broadcast receiver capable of audio / video selection processing according to a determination of whether a user views an embodiment of the present invention.

Referring to FIG. 1, the key input unit 118 generates a key data signal according to a key operation of a user and applies it to a micom 116. The memory unit 120 stores an operation program for operating the digital broadcast receiver, and stores and outputs various program information output from the tuner unit 100 under the control of the microcomputer 116.

The tuner 100 tunes and receives a bit stream of a channel corresponding to the tuning control signal of the microcomputer 116 among the bit streams received from the terrestrial wave or satellite. The channel decoder 102 decodes the signal selected from the tuner unit 100 in a VSB, QPSK, QAM, or the like manner according to a transmission method, and applies the demultiplexed signal to the demultiplexer 104.

The demultiplexer 104 receives the digital stream decoded by the channel decoder 102, divides the video stream into video, audio, and additional information streams, and applies the decoded video stream to the MPEG-2 decoder 106. Then, the MPEG decoder 106 separates and decodes the broadcast signal provided from the demultiplexer 104 into an audio signal and a video signal, and then performs a predetermined signal processing process through the video / audio processing units 108 and 110 to display the TV receiver display unit ( 112) to be displayed on the screen.

The video processor 108 receives a video signal decoded and output from the MPEG-2 decoder 106 and converts the video signal into a displayable image signal on a screen of the display 112 of a TV receiver such as a CRT, a PDP, an LCD, or the like. On the screen, the audio processor 110 receives the audio signal decoded and output from the MPEG-2 decoder 106 and reproduces the audio signal through the audio output unit such as the speaker 114.

The memo converter 124 converts the memo contents input through a key input means such as a remote controller (not shown) or the key input unit 118 into the OSD and provides the MPEG-2 decoder 106 with the MPEG-2 decoder during playback. In operation 106, the memo content inserted together with the corresponding broadcast signal may be displayed.

The time shift buffer 126 stores an image buffer for storing the broadcast video signal decoded from the MPEG-2 decoder 106, data of memo contents input by the user, and position information for the corresponding memo contents to be inserted into the broadcast signal. And a memo buffer.

The microcomputer 116 controls the overall operation of each part of the digital broadcast receiver according to the operation program stored in the memory unit 120, and generates a control signal for performing a corresponding function according to the key data from the key input unit 118. It is applied to the function part. That is, for example, the tuner 100 provides a tuning control signal for tuning a broadcast channel selected by a user, and generates a decoding control signal for decoding the tuned broadcast signal.

In addition, when there is a request for inserting a memo content into a broadcast signal during time shift recording, the microcomputer 116 receives a memo content corresponding to the broadcast signal at the time of the insertion request through the memo switch 124. By converting the memo contents into the OSD and inserting them into the broadcast screen at the time of insertion request, the memo contents can be simply recorded in the broadcast signal without additional editing procedure after the recording is completed.

2 is a flowchart illustrating a memo insertion process using a time shift function in a digital broadcast receiver equipped with an HDD according to an embodiment of the present invention. Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, the digital broadcast receiver micom 116 waits for a user's command through the key input unit 118 when the power is turned on in step S200. Accordingly, the user can select a channel for time shift viewing through the key input unit 118.

When the user selects a channel for time shift viewing as described above, the microcomputer 116 receives channel information selected by the user in step S202 and displays a broadcast signal received from the channel selected by the user in step S204. In operation S206, the displayed broadcast signal is stored in the time shift buffer 126 in the HDD 122 using the time shift function.

In this case, the user who views the broadcast signal of the selected channel may select his or her own memo content corresponding to the screen of the corresponding broadcast signal to obtain information associated with the broadcast screen when playing in any section of the broadcast signal being viewed according to the present invention. Can also be inserted.

That is, when the user requests to insert a memo in an arbitrary section of the broadcast signal during time shift recording, the microcomputer 116 recognizes a memo insertion request from the user in step S208 and proceeds to step S210 to insert a memo. Implement a memo input screen to insert a memo in the broadcast screen of the requested time.

Accordingly, the user inserts the memo contents to be input corresponding to the corresponding broadcast screen on the memo input screen. In this case, the memo content to be inserted may be input through a number and a letter key implemented in key input means such as a remote controller or a key input unit 118, and the input string may be displayed on the broadcast signal screen at the time of inserting the memo. After that, it may be input through the user's character selection by key input means such as a remote controller or a key input unit 118.

Then, the microcomputer 116 receives the memo content input by the user in step S212, and inserts the memo content input by the user in the corresponding broadcast signal in step S214 together with the screen of the broadcast signal during playback. To be displayed.

Subsequently, the microcomputer 116 completes the insertion of the requested memo to the corresponding broadcast signal at the broadcast time at which the memo insertion is requested in step S214, and then returns to the current broadcast time of the corresponding channel by using the time shift function to return the current channel. It will display the broadcast signal received from.

That is, the memo content requested to be inserted by the user is inserted into the broadcast signal of the memo point 1 requested to be inserted at the time of being actually broadcasted through the time shift function as shown in FIG. 3, and the memo is inserted. Afterwards, it returns to the point in time 3, which is actually broadcasted, and shows the currently broadcast screen to the user.

As described above, in the present invention, in a method of inserting a memo using a time shift in a digital broadcast receiver equipped with an HDD, there is a request for inserting a memo corresponding to a corresponding broadcast signal at an arbitrary broadcast time of a selected channel for time-shift recording. In this case, by inputting the memo contents corresponding to the broadcast signal and inserting the memo contents into the broadcast screen at the time of insertion request through the time shift function, the memo contents are simply added to the broadcast signal without additional editing procedure after recording is completed. You can record.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the invention should be determined by the claims rather than by the described embodiments.

As described above, in the present invention, in a method of inserting a memo using a time shift in a digital broadcast receiver equipped with an HDD, a request for inserting a memo corresponding to a corresponding broadcast signal is added at an arbitrary broadcast time of a selected channel for time-shift recording. If there is, the memo content corresponding to the broadcast signal is received and the memo content is inserted into the broadcast screen at the time when the insertion is requested through the time shift function. Thus, the memo content is simply recorded in the broadcast signal without additional editing procedure after the recording is completed. Since it can be recorded there is an advantage that the convenience of use is greatly increased.
