The present invention relates to a method and apparatus for storing received broadcast content in a storage medium in a digital broadcast receiver.

As TV technology is developed, a method of transmitting broadcast signals is also developed, and accordingly, interest in digital TV using a digital transmission method is increasing.

The digital TV has a function of storing a video in real time and playing it at a desired time using a personal video recorder (PVR) while a user is watching a broadcast. In addition, it can be used for recording meetings when conducting video conference using digital TV.

In this case, the PVR system is a system for recording or playing back a broadcast signal (digital broadcast, analog broadcast, video, etc.) by using an internal storage medium (hard disk).

Generally, a HDR (Hard Disc Recorder) system is a DVR system equipped with a hard disk (HDD), and the HDR system is capable of playing an inserted optical disk (DVD), and also records recording data on the optical disk on the hard disk. In addition to reproducing the recording, the broadcast program received through the antenna is recorded on the hard disk so that the broadcast program recorded on the hard disk is reproduced at the user's request. In addition, with the recent increase in the capacity of the memory card, not only the function of recording and playing broadcast programs on the memory card is supported, but also the trend of supporting a detachable hard disk.

PVR system supporting only one conventional storage medium For example, in a PVR system that supports only hard disks When recording a broadcast program on a disc, if the broadcast time of the broadcast program to be recorded is greater than the remaining recordable time, there is a problem in that a part of the broadcast program selected by the user cannot be recorded.

An object of the present invention, when recording the broadcast content received from the digital broadcast receiver, by comparing the remaining recording time of the recording target content and the storage medium, if the remaining time is insufficient to automatically select another storage medium to replace the corresponding broadcast The present invention provides a method and apparatus for recording control of a digital broadcast receiver, which prevents recording of all or part of broadcast content due to insufficient capacity of a storage medium.

The method of recording a program of a digital broadcasting receiver according to the present invention comprises the steps of determining whether a recordable storage medium exists before a predetermined time for recording and connecting a storage medium that can be notified to the user if the recordable storage medium does not exist. It is characterized by building.

Preferably, if the storage space is insufficient during recording, the method further comprises the step of proceeding to the recording after selecting the storage medium by determining whether there is a recordable storage medium according to the priority set by the user.

To achieve the above object, a storage medium of a digital broadcasting receiver according to the present invention determines whether or not recording is possible by checking whether a free space of a storage medium exists for the broadcast time of a program to be recorded, and records the recording medium according to a predetermined storage medium priority. And a media interface unit for transmitting / receiving a storage medium storing a program recording and an external storage medium.

Preferably, the storage medium includes a hard disk drive (HDD), a DVD recorder (DVDR), a memory card, and an external hard disk drive (External HDD).

More preferably the media interface is characterized in that it comprises an IEEE1394, USB (USB), memory card slot , PCI slot.

Hereinafter, a program recording method and apparatus of a digital broadcast receiver according to the present invention will be described in detail with reference to the accompanying drawings.

A multiplexer 104, a decoder 106 for decoding the separated audio and video signals, an output 108 for outputting the decoded audio and video signals, and tuning and recording / playback control of the broadcast channel A control unit 110 for recording, a media interface unit 112 for recording and reproducing processing and path control of broadcast content, and a storage medium unit 114 connected to the media interface unit 112 to store broadcast content. do. The storage medium unit 114 is composed of at least one or more storage media. Here, the storage medium unit 114 includes a HDD, a DVDR, a memory card, and an external HDD as a storage medium that can be connected. It is based on a structure that can freely connect or separate media. The output unit 108 includes a speaker device and a display device (LCD, PDP, CRT, etc.).

Referring to the operation of the digital broadcast receiver according to the embodiment of the present invention as described above is as follows.

The tuner unit 110 receives the digital broadcast signal, and the demodulator 102 demodulates the received broadcast signal and restores the original signal.

The demultiplexer 104 separates the signal demodulated by the demodulator 102 into a video and audio signal, and the decoder 106 decodes the original video and audio signal into the decoder 106. Video and audio signals decoded by It is output to the user by the output unit 108.

The media interface unit 112 It transmits a signal to store the video and audio signals separated by the demultiplexer 104 in the storage medium 114, and reads the signals to be decoded from the storage medium 114 to the decoder 106. It serves to convey.

At this time, the controller 110 determines whether or not there is a free space of the storage medium 114 for the program to be recorded by the user from among the storage media. According to the priority set by the user, the next priority storage media is selected to control recording.

When there is no free space to record at all on the currently mounted storage medium 114, the controller 110 allows the user to connect a storage medium 114 that can be notified that there is no free space.

The storage medium 114 is removable so that the user can connect to another storage medium while recording. The storage medium 114 is not only removable, but also capable of moving audio / video files between storage media, and provides a user interface for transmitting files between the storage media in a digital broadcasting receiver.

2 is a flowchart illustrating a program recording method of a digital video receiver according to the present invention.

According to FIG. 2, it is checked whether a program to be recorded exists (S200).

It is checked whether the recording time is reserved by the user (S202), and whether or not a storage medium capable of recording is present (S204).

Judgment of step 204 As a result, if no recordable storage medium exists, the user is notified that the recordable storage medium is not connected in the form of an OSD-based message or a voice notification (S206).

Judgment of step 204 Result If a recordable storage medium exists, recording is performed.

After notifying that there is no recordable storage medium, Connected recordable storage media Check whether or not (S208).

If a recordable storage medium is connected or there is another recordable storage medium in step S204, the recording medium is selected and recording is performed (S210).

Judgment of step 208 Result If the user has not connected a recordable storage medium Stop recording.

next, Search whether the storage space is insufficient during recording (S212). As a method of searching / determining whether the storage space is insufficient during recording, information on the remaining capacity of the storage medium and the amount of broadcast content to be recorded is used. If the remaining capacity of the storage medium is smaller than the amount of broadcast content to be recorded, the storage space is insufficient. Therefore, the storage medium to be replaced is selected. If the storage space is sufficient, recording is continued on the currently selected medium.

In other words, Step 212 judgment If the result storage space is insufficient, it is searched whether there is another storage medium that can be recorded subsequently (S214).

Step 212 judgment If the result storage space is not short, the recording is continued (S218).

Step 214 Decision As a result, if there is a storage medium that can be recorded subsequently, the next storage medium is selected according to the priority selected by the user, and recording is performed (S216 and S218).

In this way, the recording can be continued by automatically selecting another storage medium as an alternative storage medium according to a predetermined ranking, or when the user is expected to run out of capacity, a menu screen prompting the user to select an alternative recording means (storage medium). If the user selects another alternative recording means in consideration of the remaining capacity or the like, the recording may be continued to the selected storage medium.

Step 214 Decision Result If the recordable storage medium does not exist, the user is notified that there is no recordable storage medium.

3 is an exemplary screen illustrating a process of determining the priority of a storage medium of a digital broadcast receiver according to the present invention.

Referring to FIG. 3, the priority selection screen includes a priority number 200 indicating a storage medium to be recorded first and a storage medium selection cell indicating the type of the selected storage medium corresponding to the priority number 200. 201 and a size information cell 202 representing a free space of each storage medium, the key input unit to be implemented in the remote control or OSD The navigation buttons 204 and 206 for selecting the type of storage medium to be stored, and the selection button 208 for selecting the storage medium.

The priority number 200 indicates a storage medium to start the first storage from No. 1, and the higher the number, the lower the priority.

The media selection cell 201 indicates the type of storage medium that can be stored.

The size information cell 202 allows the user to check the remaining space of the storage medium, so that the remaining storage time can be easily selected in consideration of the remaining time to be recorded.

The up button 204 and the down button 206 of the remote controller are used to select or move a storage medium according to the priority number 200.

The select button 208 of the remote controller is used to select a storage medium or determine the type of the priority cell.
