According to FIG. 1, the image recording / reproducing apparatus 100 includes a signal receiving unit 110, a switching unit 120, a signal processing unit 130, and a recording medium 140.

The signal receiver 110 may receive a data stream having an MPEG format from an image reproducing medium such as a broadcasting station or a DVD as an input signal. Each of the signal receivers 111 and 112 may be implemented as a tuner for receiving a broadcast signal and an external input terminal for receiving a video signal from an external medium.

When a processing command is input to a received input signal, the switching unit 120 selectively selects at least one of a signal processing unit 130 and a recording medium 140 capable of processing the received input signal in a form capable of outputting the received input signal. Switch. That is, when a recording command is input to the input signal, the input signal is transmitted to the recording medium 140, and when a playback command is input, the signal is transmitted to the signal processor 130. In addition, when recording and reproducing commands are input to the input signal, the signals are simultaneously transmitted to the signal processor 130 and the recording medium 140.

 2 is a block diagram showing a configuration of an image recording / reproducing apparatus according to another embodiment of the present invention. According to FIG. 2, the image recording / reproducing apparatus 100 may include a user interface 150 and a controller 160 in the configuration of FIG. 1. Meanwhile, the functions of the signal receiver 110 and the switching 120 are the same as the description of FIG. 1.

The user interface unit 150 receives a processing command for an input signal. Here, the user interface unit 150 may be implemented as a key input unit (not shown) and a display unit (not shown). That is, the display unit of the user interface unit 150 displays a user interface for selecting a processing command for each input signal, and provides the user interface, and the key input unit receives a processing command by the user's selection.

The controller 160 controls the switching unit 120 to select the signal processor 130 when the processing command selected by the user interface 150 is a recording command, and the recording medium 140 when the selected processing command is a storage command. Control to select. In addition, when the selected processing command is a recording and reproducing command, the switching unit 120 is controlled to select the recording medium 140 and the signal processing unit 130 together.

In addition, when the first input signal is input through one of the plurality of signal receivers 111 and 112, and a reproduction command for the first input signal is input through the user interface unit 150, the first control unit 160 receives the first input signal. The input signal is transmitted to the signal processor 130, a second input signal is input through the other one of the plurality of signal receivers 111 and 112, and a recording command for the second input signal is input through the user interface unit 150. When input, the switching unit 120 is controlled to transmit the second input signal to the recording medium 140. The switching operation of the switching unit 120 under the control of the controller 160 may be described with reference to FIG. 3.

3 is a view for explaining a switching method according to an embodiment of the present invention. 3A is a diagram showing switching when a recording or reproducing command is input to two different channels. According to FIG. 3A, a playback command is input to the first input signal received through the first signal receiver 111 and a recording command is written to the second input signal received through the second signal receiver 112. In this case, the switching unit 120 connects the first signal receiver 111 and the signal processor 130 and the second signal receiver 112 and the recording medium 140.

FIG. 3B is a diagram showing switching when a switching command is input during playback and recording processing as shown in FIG. According to FIG. 3B, the switching unit 120 switches the first input signal received through the first signal receiver 111 to be transmitted to the recording medium 140, and the second signal receiver 112. The switching state is switched to transmit the second input signal received through the signal processor 130. That is, the switching unit 120 connects the first signal receiver 111 and the recording medium 140 and the second signal receiver 112 and the signal processor 130. In this case, the recording command and the reproduction command can be converted and processed without channel retuning, thereby reducing the time spent in channel retuning.

3C is a schematic diagram showing switching when a reproduction and recording command is input for a single channel. According to FIG. 3C, it can be seen that the signal processor 130 and the recording medium 140 are switched to the signal receiver 110. That is, the received single input signal may be reproduced through the signal processor 130 and stored at the same time on the recording medium 140.

When the playback command is input to the input signal stored in the recording medium 140, the controller 160 controls the switching unit 120 to block the previous input signal switched to the signal processing unit 130, and the recording medium 140. Read out the input signal stored from the control to transmit to the signal processor 130.

The signal processor 130 is a demux 131 for dividing the input signal which is switched and input into a video signal and an audio signal, and an MPEG for decoding the video signal and the audio signal output according to the MPEG format from the de-mux 131. The decoder 132 may be implemented as an output unit 133 for outputting a decoded audio signal and a video signal.

The recording medium 140 may be an internal recording medium 141 or an external recording medium 142, and may store an input signal according to a user's selection. Here, the input signal stored in the recording medium 140 is a signal in which a video signal and an audio signal in MPEG format are compressed. The recording medium 140 may be a hard disk drive, a semiconductor memory, an optical recording medium, a magnetic recording medium, or the like.

Accordingly, it is possible to reproduce the specific input signal by switching the input signal according to the recording or reproducing command for the input signal, and to record another input signal.

4 is a flowchart illustrating a video recording / reproducing method according to an exemplary embodiment. According to FIG. 4, at least one of a reproduction and a recording command is received with respect to an input signal received from a tuned channel (S410). In this case, when the selected input is a playback command (S420), the input signal is transmitted to the signal processor (S430) and reproduced in a form that can be output. When the selected input is a recording command (S420), the input signal is transmitted to the recording medium. It is stored (S440).

Here, the input signal may be received from a single channel or may be an input signal respectively received from a plurality of channels. When a reproduction and recording command is input to an input signal received from a single channel, the input signal is simultaneously transmitted to the signal processor and the recording medium.

On the other hand, when an input signal is received from a plurality of channels, one channel can be reproduced and the other channel can be recorded at the same time. When a play command is input to an input signal stored in a recording medium among the input signals of a plurality of channels sequentially tuned (S450), reception of the input signal being reproduced is blocked and the stored input signal is read and transmitted to the signal processor. (S430).

5 is a flowchart illustrating a method of switching a reproduction and recording command of a preset input signal. When a reproduction command is input to the first input signal received from the first channel, the received first input signal is switched to the signal processing unit for reproduction (S510), and a recording command for the second input signal received from the second channel. When the input, the received second input signal is switched to the recording medium and stored (S520).

In this case, when a switching command is input (S530), the first input signal may be switched to the recording medium and stored, and the second input signal may be switched to the signal processor to reproduce the signal (S540). In other words, the switching and playback commands can be converted by controlling the switching without having to re-tune each channel. Therefore, it is possible to reduce the time spent in re-tuning.

As described above, according to the present invention, it is possible to simultaneously process reproduction and recording by selectively switching a path to which an input signal is transmitted. Accordingly, when a single input signal is input, the input signal is switched to be simultaneously transmitted to the recording medium and the signal processing unit. When a plurality of input signals are input, the input signal is switched to process recording on one input signal, and playback is performed on another input signal. Switch to processing.

In addition, the use of a single de-mux and a single decoder can reduce costs in the manufacture of a video recording / reproducing apparatus.

In addition, the input signal may be transmitted not only to the internal recording medium but also to the external recording medium.

In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the above-described specific embodiment, the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Of course, various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
