The present invention relates to a new recording display device and method, and more particularly, to a broadcast receiver having a DVR function, in which a recorded alarm message to be overlaid when a system initial screen starts when there is a program recorded but not watched by a user is overlaid with a broadcast signal. It relates to how to display.

In general, a personal video recorder (PVR) device is equipped with a nonvolatile storage device in a TV or a set top box to record a broadcast signal or other external input signal so that a user can watch and record a recorded program when desired. Device to ensure that

Recently, the demand of digital broadcasting receivers equipped with DVR function is gradually increasing in each home, and the digital broadcasting receiver equipped with such DVR function stores predetermined broadcast streams received from the broadcasting network on a hard disk installed therein. Output and play back at the time you want.

In particular, the digital broadcasting receiver enables scheduled recording without the addition of a separate recorder due to this DVR function. In general, the reserved recording of the digital broadcasting receiver equipped with the DVR function allows the user to specify each time and channel information. In this way, the broadcast program is manually performed through the EPG (Electronic Program Guide).

Recently, a digital broadcast receiver DVR (Digital Video Recorder) product for embedding a storage medium such as a hard disk and recording / reproducing a digital broadcast with the diffusion of a digital broadcast receiver has been released.

These DVR products are expected to rapidly replace existing VCR (Video Cassette Recorder) products due to the full-fledged digital broadcasting. The digital broadcasting receiver DVR is equipped with a high performance CPU and uses a method of recording digital broadcasting programs on a storage medium such as a large capacity hard disk (HDD) in a file unit so that the stored programs can be easily searched for, and repeated playback and editing can be easily performed. There is an advantage that you can watch.

In addition, the digital broadcast receiver DVR provides an electronic program guide function called an electronic program guide (EPG) to increase user convenience. It can be thought of as a full program schedule that is broadcast on the day as seen in the newspaper. The user can pre-record a desired program in advance using the EPG data or store a category, title, and plot together with the program.

In particular, the category information is divided into major categories, mid-classes, and small classes, although there are some differences among broadcasters, and includes characteristic information about a program that is currently being watched or recorded.

The conventional method for recording a broadcast program using a conventional digital broadcast receiver DVR is simple. In order to schedule recording of general program, you can set the time and duration you want to record by using DVR remote control or schedule recording using EPG program data.

The PVR device displays the recorded video to the user in the form of a list, but if the user uses the scheduled recording function or does not watch immediately after recording, the user must check the recorded video list by operating the remote control to check the unrecorded video. .

Therefore, there is a need for a method in which a user can easily recognize and access a new recording.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide a user with a list of new recordings when the PVR device is powered on.

Another object of the present invention is to provide a user with a list of recordings that the user did not watch when powering on.

According to one aspect of the present invention, a recording display device includes: a user interface for receiving a recording signal and a power supply signal from a user; A controller for generating a recording file and an execution file descriptor of the corresponding video data according to the recording signal, searching for the execution file descriptor of the recording file by inputting the power supply signal, and extracting the execution file that is not executed; A hard disk configured to store data information of the recording file and the execution file descriptor; And an image processor for overlaying the extracted recording file alarm message with the received broadcast signal stream and outputting the same.

In addition, the present invention provides a method for displaying a recording of a broadcast receiver, the method comprising: extracting a recording file that is not played by searching a file descriptor for executing a recorded multimedia file; And outputting a recording file alarm message when the recording file is not played.

The objects, features and advantages of the present invention will be more readily understood by reference to the accompanying drawings and the following detailed description. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the description thereof will be omitted.

1 is a block diagram showing a broadcast receiver having a DVR function according to the present invention.

The tuner 10 receives a broadcast signal corresponding to a channel selected by a user according to a power supply signal. A register according to a channel selected by a user is set, and a broadcast signal having a frequency band corresponding to the set value is received. The QAM signal, which is a VSB or digital cable signal output from the tuner 10, is demodulated into a TS (Transport Stream) to be separated into a video, audio, and data stream. The digital video signal is temporarily stored in the buffer, and the broadcast signal is sequentially stored in the HDD 70.

The decoder 20 extracts and decodes the digital video signal compressed by the MPEG method from the HDD 70.

The image processor 30 converts the decoded video signal into an analog video signal and outputs the data signal by overlaying it with the OSD (On Screen Display) method.

The output unit 40 combines the recorded file alarm message according to the present invention with a broadcast signal and outputs the synthesized signal.

The user interface 50 receives a power supply signal and calls a recording file alarm message at system initialization to access a list of recording files to play.

The controller 60 detects the recording signal input from the user interface 50 and records the corresponding digital multimedia broadcasting program to be reproduced. At this time, the file descriptor whether the recorded multimedia file is executed is attached. The execution file descriptor changes and updates the recorded recording file information when the recording file is played by the user.

The hard disk 70 stores the recorded broadcast signal in the form of TS (Transport Stream) or PES (Packet Elementary Stream) and stores a recording file database including a file descriptor.

2 is a block diagram showing the function of a recording display device in the broadcast receiver of the present invention.

Record a multimedia broadcast signal to be played to create a file descriptor for execution of a recorded file. The executable file descriptor is provided to determine whether to play the recorded file. The execution file descriptor is 'Y' and the execution file descriptor is executed as 'N' (S200).

The execution file descriptor search unit extracts the execution file descriptor from the recording file database stored in the hard disk in the system initial ON state according to the power supply signal of the system input through the user interface. At this time, if there is a recording file that has not been executed, the controller overlays the recording file alarm message with the broadcast signal of the channel to be output (S201).

 The non-executed recorded files retrieved from the file descriptor searching means are listed in order of the latest recorded time and are provided as recording file information to be reproduced by the user as a lower item in association with the recorded file alarm message (S202). The recording file list provides functions of editing and deleting the selected recording file.

 The power supply signal through the user interface is detected to initialize the system of the broadcast receiver (S300 and S301). The controller searches for a file descriptor indicating whether a recorded file is executed from the recorded file database of the hard disk (S302). Whether the recorded file is executed or not is detected through the file descriptor (S303). If a new or unplayed recorded file exists, the recorded file alarm message is overlaid with the broadcast signal and output to the screen display unit (S304). Receiving the recording confirmation signal associated with the alarm message through the user interface to display the list of recording files stored in the latest time sequence (S306). When a new or unplayed recording file does not exist or the recording confirmation signal is not input through the user interface during system initialization of the broadcast receiver, the broadcast receiver performs the corresponding function of the broadcast signal output and the signal input through the user interface ( S307).

Represents a database including a list of recorded files stored in the hard disk of the broadcast receiver and whether or not file descriptors (N, Y) are executed. The title of the recording file can be entered by using the user interface and can be updated and stored with numeric information during automatic saving. The recording date of the recording file is listed in chronological order. The file descriptor detects the recording file indicated by 'N' during system initialization. The recording file list includes recording time, recording length information, and the like.

5 is a diagram illustrating a broadcast signal and a recording display alarm on a screen of a broadcast receiver according to an exemplary embodiment of the present invention.

The broadcast receiver receives a power supply signal and processes and outputs a broadcast signal of a channel CH.7 that is initialized and received by the system. At this time, if there is a recording file to be played by searching the file descriptor for execution from the recording file database of the hard disk, the recording file alarm message is overlaid with the broadcast signal and displayed. The recording file alarm message may be provided in various display methods according to user menu settings, such as flickering of text output or displayed as a specific alarm voice signal.

Although the invention has been described in detail only with respect to the specific examples described, it will be apparent to those skilled in the art that various modifications and variations are possible within the spirit of the invention, and such modifications and variations belong to the appended claims.

The present invention searches for whether a recording file is executed during system initialization of the broadcast receiver, and outputs a recording file alarm message by overlaying a recording file alarm message with a received broadcast signal when a new recording or a non-playing recording exists. There is an effect that is achieved simultaneously with the broadcast viewing function without using any other means to do so.
