Description

Record simultaneously seeing and hearing possible Apparatus for digital broading different each other}

The present invention relates to a device capable of simultaneously recording and viewing different digital broadcasts capable of smoothly watching different digital broadcasts while recording digital broadcasts using the PVR function.

PVR is a personal digital video recording device that records and plays back information on a hard disk. Unlike a VCR that stores video signals on a magnetic tape, a PVR is a new concept of digital recording device that records and plays back information on a hard disk. It is a next-generation recording device that can record a certain amount of broadcast programs depending on the capacity without a VCR through the hard disk drive built into the set-top box or television body.

When the PVR selects a channel, the signal currently broadcasted on the hard drive is digitally stored and played simultaneously. Therefore, if the stop button is pressed and the play button is pressed again, the stored broadcast signal is played again from the point where it was stopped. You can also watch the program that's currently being broadcast, play it back in slow motion, or skip the boring part, making it easy to find and edit the part you want.

In the future, as analog broadcasting ends, the function of the existing DTV receiver is expected to change significantly, and the PVR function, which is currently being issued, has many advantages in terms of users.

Hereinafter, the PVR will be described in detail with reference to the accompanying drawings.

1 is a block diagram schematically showing the configuration of a PVR.

Referring to FIG. 1, the PVR includes an IR receiver 100, a microcontroller 110, a tuner 120, a first decoder 130, a multiplexer 140, a video processor 150, a video outputter 160, The display unit 170, the TP control unit 180, the IDE unit 190, and the HDD 200 are included.

The IR receiver 100 receives the remote control code selected by the user and transmits the code to the micro controller 110.

The micro controller 110 analyzes a remote control code transmitted from the IR receiver 100 and transmits remote control code analysis information to a corresponding device.

For example, if the remote control code interpretation information is a channel change request command, the micro controller 110 transmits the channel change request command to the tuner 120, and the remote control code interpretation information is applied to the data stored in the HDD 200. If it is a play command, the micro controller 110 transmits a play command of the stored data to the multiplexer 140.

The microcontroller 110 will be described in more detail. The microcontroller 110 includes a second decoder 112, a CPU 114, and a storage 116.

The second decoder 112 interprets the remote control code transmitted from the IR receiver 100 and transmits the code to the CPU 114.

The CPU 114 transmits remote control code interpretation information transmitted from the second decoder 112 to a corresponding device such as a tuner 120, a multiplexer 140, and extracts the corresponding software from the storage unit 116. Operate.

The storage unit 115 includes a flash ROM 117 for storing software such as an operating system and a DRAM 118 for storing a virtual screen in a bitmap form that can be represented in a CRT area.

The tuner 120 converts the radio signal transmitted through the antenna into an IF signal according to the analysis information of the remote control code selected by the user and transmits the converted radio signal to the IF decoder 130.

The first decoder 130 converts the IF signal transmitted from the tuner 120 into TP data and transmits the TP data to the multiplexer 140.

The multiplexer 140 selects the corresponding data according to the data selection command of the remote control code analysis information transmitted from the micro controller 110.

For example, if the data selection command of the remote control code interpretation information is a program selection command transmitted from the first decoder 130, the multiplexer 140 selects a program transmitted from the first decoder 130 and performs a time shift. If it is a command for selecting stored data, the data is time-shifted to select the stored data.

In addition, the multiplexer 140 stores the TP data transmitted from the first decoder 130 through the microcontroller 110 when the remote control code interpretation information is a storage command of the TP data transmitted from the first decoder 130. Transfer to HDD 200.

The video processor 150 converts the TP data transmitted from the multiplexer 140 into image data and transmits the image data to the video output unit 160.

The video output unit 160 corrects the image data so that the image data transmitted from the video processor 150 is displayed to match the display unit 170.

When the TP data storage command is received from the micro controller 110, the TP controller 180 transmits the transmitted TP data to the HDD 200 through the IDE unit 190.

In addition, when the TP controller 180 receives a time-shifted data playback command from the micro controller 110, the TP controller 180 receives the time-shifted data stored in the HDD 200 through the IDE unit 190. To 110.

The HDD 200 stores data transmitted from the IDE unit 190.

Hereinafter, the operation of the PVR configured as described above will be described.

The remote control code selected by the user is transmitted to the second decoder 112 through the IR receiver 100. The second decoder 112 analyzes a remote control code transmitted from the IR receiver 100 and transmits remote control code analysis information to the CPU 114.

The CPU 114 extracts and operates the software corresponding to the remote control code interpretation information transmitted from the second decoder 112 in the flash ROM 117 and operates the device corresponding to the remote control code interpretation information. For example, if the remote control code interpretation information is a channel change request command, the CPU 114 adjusts the tuner 120 and then tunes the TV frequency to catch the TV signal.

The input TV signal is converted into a TP signal while passing through the first decoder 130 and transmitted to the video processor 150. The video processor 150 converts the TP signal into image data and transmits the image signal to the display unit 170 through the video output unit 160.

In addition, when the remote control code input by the user is a command for displaying a menu for adjusting a function on the screen, the CPU 114 may execute a predetermined memory area of the DRAM 118 according to a command of a program code stored in the flash ROM 117. And configure a virtual screen as a bitmap capable of expressing a menu on the display unit 170 in the allocated area.

The bitmap created in the DRAM 118 is transmitted to the video processor 150, and the video processor 150 synthesizes the video inputted through the first decoder 130 and the OSD generated by the micro control unit 110. The display unit 170 transmits to the display unit 170 through the output unit 160.

The time-shifted data is temporarily stored in the HDD 200, and when a request for reproducing the temporarily stored data is received, the temporary stored data is transmitted to the multiplex 140 through the IDE unit 190 and the TP controller 180. Delivered. Then, the multiplex 140 selects input data and transmits it to the video processor 150, and the video processor 150 converts the transmitted TP data into image data and outputs the image data through the video output unit 160. do.

However, conventionally, when recording the currently received digital broadcast using the PVR function, other digital broadcasts cannot be received. If you want to receive other broadcasts while recording with the PVR function, there is an inconvenience of switching to the analog and receiving. .

Accordingly, an object of the present invention is to provide a device capable of simultaneously recording and watching different digital broadcasts capable of receiving different digital broadcasts while recording digital broadcasts using the PVR function.
