Abstract

A system and a method for recording digital broadcasting programs are disclosed. The system executes the clipping function that allows a user to select a portion of a recorded video signal, time-shifted video signal, or real-time broadcasting video signal through a guide bar in an OSD form, and stores only the video signal of the selected portion in an HDD. This prevents the HDD from being unnecessarily wasted and allows the user to easily perform the clipping function. Even a time-shifted program is stored in the HDD through the clipping function so that the user can reproduce the time-shifted program whenever he wants to watch it.

a storage medium for storing a corresponding broadcasting signal when a recording or time shift function is set;

a key input unit through which a user inputs a clipping start key and a completion key at the start position and end potion of a clipping region in order to set the clipping region in a broadcasting signal being displayed, the key input unit transmitting user'"'"'s commands in wired or wireless;

an application for controlling the entire system in order to perform operations according to commands of the key input unit;

an OSD unit for displaying a guide bar in an OSD form on a predetermined position of a screen under the control of the application in order to display the state of the broadcasting signal currently being displayed, the clipping region being distinctively indicated on the guide bar;

an engine for processing a video signal reproduced from the storage medium or a real-time broadcasting video signal to display the processed signal under the control of the application, the engine controlling only broadcasting signals of the clipping region to be stored in the storage medium when the user sets the clipping region through the guide bar; and

a file system for managing information about files stored in the storage medium, the file system generating a new file name and correcting existing file information when the broadcasting signals of the clipping region have been stored.

2. The system as claimed in claim 1, wherein the user moves a cursor to a desired clipping start point on the guide bar and inputs a start key for clipping, and then he moves the cursor to a desired clipping completion point and inputs a completion key for clipping, to thereby set the clipping region, the user setting a plurality of clipping regions by repeating the above-described process, the guide bar being displayed, being linked with the displayed broadcasting signal.

3. The system as claimed in claim 1, wherein the OSD unit displays the clipping region and other regions in different colors under the control of the application, to allow the user to recognize the clipping region.

4. The system as claimed in claim 1, wherein the start key and completion key for clipping are allocated to one key of the key input unit and the clipping region is set by toggling the key.

5. The system as claimed in claim 1, wherein the start key and completion key for clipping are respectively allocated to different keys of the key input unit, to set the clipping region.

6. The system as claimed in claim 1, wherein the broadcasting signal of the clipping region is a broadcasting signal that is stored in the storage medium through the recording function and then reproduced.

7. The system as claimed in claim 1, wherein the broadcasting signal of the clipping region is a broadcasting signal that is stored in the storage medium through the time shift function and then reproduced.

8. The system as claimed in claim 1, wherein the broadcasting signal of the clipping region is a broadcasting signal received through a channel in real time.

9. The system as claimed in claim 1, wherein the engine deletes broadcasting signals excluded from the clipping region, among reproduced broadcasting signals, when the displayed broadcasting signal is a broadcasting signal stored in the storage medium through the recording function and, simultaneously, updates file information of the file system.

10. The system as claimed in claim 1, wherein the OSD unit displays file information stored in the storage medium in a list form with reference to the file system under the control of the application, and the user selects files he wants to merge into one file from files of the list and determines merging order of the selected files.

11. A method of recording broadcasting programs of a digital TV system including a storage medium for storing a corresponding broadcasting signal when a recording or shift time function is set and a file system for managing information of files stored in the storage medium, the method comprising the steps of:

(a) displaying a guide bar on a predetermined position of a TV screen in an OSD form and indicating the state of a broadcasting signal currently being displayed on the guide bar;

(b) a user inputting a start key and a completion key for clipping at a desired clipping start point and an end point on the guide bar, to set a clipping region, when the user wants to set the clipping region from the displayed broadcasting signal;

(c) discriminating the clipping region from other regions on the guide bar when the clipping region is set in the step (b) and

(d) storing only the broadcasting signal of the clipping region in the storage medium and updating file information of the file system when the clipping region is set in the step (b).

12. The method as claimed in claim 11, wherein, in the step (b), the user moves a cursor to a desired clipping start point on the guide bar and inputs a start key for clipping, and then he moves the cursor to a desired clipping completion point and inputs a completion key for clipping, to thereby set the clipping region, the user setting a plurality of clipping regions by repeating the above-described process, the guide bar being displayed, being linked with the displayed broadcasting signal.
