Abstract

PURPOSE: A system for manufacturing an image album using a motion picture capture system on a digital television and a method therefor are provided to capture motion pictures, and to store the motion pictures in a set top box, then to display stored images in image album type as transmitting a desired image to other media, thereby enabling a TV viewer to easily edit/manage captured images. CONSTITUTION: A motion picture capture unit(60) executes a motion picture capture program decoded through an information decoder(55), and captures a desired screen when a user presses a button by using a remote controller to capture the desired screen on TV. An image storage(70) converts captured image data into a motion picture capture image by using a compression format, and stores the converted motion picture capture image in an RAM. An image display(80) displays at least more than one motion picture capture image stored in the image storage(70) on a TV screen in picture album type. An image editor(90) selects a desired image, and controls a color or effect of the selected image.

Description

System for producing image album on digital television receiver using moving image capture and method therefor}

The present invention relates to a system and method for producing an image album by capturing a moving picture played on a television screen through digital broadcasting.

Conventionally, as digital broadcasting starts, DVB-MHP has been selected as a standard for satellite broadcasting. As a result, while one channel of the existing video can be transmitted, four channels can be transmitted simultaneously by transmitting with MEPG-2 compression. In addition, by utilizing a wide bandwidth, data broadcasting, which was previously broadcast simply based on text, can provide high quality services with various functions using various effects such as graphics and images as well as sound.

Conventionally, in order to capture a video played on a television, a video is recorded using another medium having a recording function such as a VTR, the recorded video is stored in a predetermined memory block, and then loaded into a computer to capture and edit the video. Since it was necessary to edit using a software program that performs a function, it was necessary to purchase expensive software for capturing or editing a video. The process and method were complicated because the video capturing step and editing of captured image images were separated separately. There was a problem of investing time and money.

An object of the present invention for solving the above problems is to capture video scenes broadcast through a television, store them in a set-top box of the television, display the stored images on the screen in the form of an image album through the television, the desired image The present invention provides a system and method for producing an image album using video capture on a digital television for allowing viewers to easily edit and manage the captured images by allowing them to be transmitted to other media.

DETAILED DESCRIPTION Hereinafter, detailed descriptions of conventionally known technologies that do not correspond to the gist of the present invention will be omitted. Referring to the drawings,

In a set-top box that can receive a digital broadcast signal or a television that is built-in such a set-top box,

A broadcast signal receiver 20 for receiving a stream of digital broadcast video data, audio data, and information data from the broadcast station 10 and a broadcast signal received through the receiver 20 are converted to MPEG-2 TS (Transport Stream). A demodulator 30 for converting to a stream, a demultiplexer 40 for extracting a broadcast signal of a channel selected by a viewer from the TS stream converted by the demodulator 30, and a compression for extracting the extracted broadcast signal. The video / audio decoding unit 50 and the information decoding unit 55, which decode by a moving picture export group phase (MPEG) method, which is a standard method, and a video in the form of a Java application (Xlet) decoded by the information decoding unit 55. A video capture unit that executes a capture program to capture a screen of the moment a button is pressed by using a remote controller when a desired scene comes out from a video provided on a television screen. 60; An image storage unit 70 for converting the captured image data into a moving image captured image using a compression format such as JPEG and storing the image data in an internal hard disk or RAM; An image expression unit 80 for displaying at least one video capture image stored in the image storage unit 70 in a photo album format through a television screen; An image editing unit 90 for adjusting a color or an effect of an image by selecting a desired image among images shown on the screen of the image expression unit 80; The image transmitting unit 100 selects a desired image among the images shown in the photo album format and transmits the image to another computer, server, or mobile phone terminal connected to the set-top box through the Internet or wireless network.

The graphic processor 56, which is not described, is a block for synthesizing the decoded video / audio data and information data and processing the graphics. The display device 57 is a display device such as a digital television monitor or LCD. The control unit (not shown) for controlling the operation of the box or the television with such a set-top box may use a control method using a conventional microprocessor, and thus detailed description thereof will be omitted.

The operation of the set-top box of the present invention as described above will be described in detail based on the flowchart of FIG. 2.

The present invention shows a flow of execution of a television album using video capture, and receives an MPEG-2 stream produced by muxing digital broadcasting audio data, video data, and information data stream transmitted from a broadcasting station in a set-top box. And separate into respective streams (step S 201);

The separated audio data is reproduced in the speaker through the decoder, the video data is reproduced in the display screen of the television through the decoder, and the information data is also decoded through the decoder, among the decoded information data, in particular, to produce an image album of the present invention. An application program (application program) is executed and displayed on the television screen (step S202);

Next, the user presses a snapshot button of the remote controller in the scene to be stored in the video played through the remote controller (step S203);

Then, the current screen is captured immediately (step S 204), and the user is asked whether the captured scene is to be shown and stored in a predetermined area of the screen (step S 205);

If you want to capture a screen you do not want, you can capture another screen without saving it.If you save the screen you want, you can convert the captured screen to a video image and compress the image to save a small amount of the image. Format (compressed format such as JPEG) method (step S206) and store in a memory built in the set-top box (step S207);

The user repeats this operation and stores several images. Then, when the user clicks a button called a television album displayed by the execution of the application program (step S208), the application file is executed to store the stored images in the form of a photo album. Displayed on the screen (step S 209);

The user can select a desired image and process it into an image that has a color and a drawing effect (bright, dark, inverted, etc.) that the user desires (steps S 210 to S211), and immediately converts it to an internet network or other communication network. It may be transmitted to another computer or server connected to the set-top box or other medium such as a mobile phone terminal (steps S212 to S213); When delivered via e-mail, the selected image is provided as an attachment and the person receiving the e-mail can receive the captured image.

The effect of the present invention having the above configuration is that by simply capturing and storing a desired screen at the moment desired by the viewer, the video provided through the television can be easily obtained simply by watching a television without using a television capturer or a computer. It has an effect.

In addition, by storing these images in a set-top box and managing the stored images through a TV album, there is an effect of efficiently processing, storing, and displaying images without mobilizing other equipment.

In addition, the user interface (UI), which is provided so that the viewer can conveniently use only a simple remote control operation through the TV album, also provides additional effects, for example, the UI can be used as a means of advertising.
