There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an embodiment of a digital broadcast receiver for storing / purchasing a video scene according to the present invention. In detail, FIG.

Here, since the general structure of the digital multimedia broadcasting (DMB) receiving terminal and the like are well known technologies, the present invention will be described with reference to the video scene processing unit, which is the core technology of the present invention, and other components will be described in detail. The description will be omitted.

As shown in FIG. 1, a video scene processing unit of a digital multimedia broadcasting (DMB) receiving terminal according to the present invention includes a receiving unit (not shown) for receiving a digital multimedia broadcasting (DMB) signal, and through the receiving unit. A video decoding block 10 for decoding a video stream among the signals included in the received digital multimedia broadcasting (DMB) signal, and a video output for outputting (displaying) the video stream decoded by the video decoding block 10. Block 20, temporarily storing / managing video frames at a corresponding point in time according to a video frame capture command from a user while watching a broadcast, and supporting a payment / purchase procedure for the temporarily stored video frames after watching a broadcast. Video frame temporary storage / management block 30, and the video frame temporary storage / management And a store terminal 40 to store the corresponding video frame to the purchase in accordance with the control of the block 30.

Next, the configuration and operation of each component will be described in more detail as follows.

First, a receiver (not shown) of a digital multimedia broadcasting (DMB) terminal receives a digital multimedia broadcasting signal. The digital multimedia broadcasting signal received as described above is divided into a video stream, an audio signal, and additional data and transmitted to a corresponding processing block, as is known.

Then, the video decoding block 10 receives a video stream from the signals included in the digital multimedia broadcasting signal received by the receiver, decodes it, and delivers the video stream to the video output block 20.

Then, the video output block 20 receives the decoded video stream from the video decoding block 10 and outputs (displays) the screen. That is, the decoded video stream is output to the user. In this case, the user may give a signal (video frame capture command) to store a desired video scene as if the user presses the shutter of the digital camera while watching the digital multimedia broadcasting. That is, the user may input a video frame capture command to the video output block 20 through an input device such as a remote controller or a voice command. Of course, it will be obvious that the video frame capture command may be implemented through a block other than the video output block 20. Accordingly, the video output block 20 transfers the video frame at the time of receiving the video frame capture command to the video frame temporary storage / management block 30.

Then, the video frame temporary storage / management block 30 serves to temporarily store and manage the video frame selected by the user received from the video output block 20. As a result, the video frame temporary storage / management block 30 performs a function of temporarily storing / managing a video frame at a corresponding point in time according to a video frame capture command from a user while watching a broadcast.

On the other hand, after watching the broadcast, the user can store the video frame temporarily stored at a desired time by paying for the terminal storage 40 according to the purchase. That is, according to a known payment / payment procedure, a process for searching / selecting and purchasing a video frame to be purchased from among video frames temporarily stored in the video frame temporary storage / management block 30 is performed by a specific processor (eg After performing in the central processing unit (not shown in the drawing), when the specific processor transmits a storage command of the video frame to the video frame temporary storage / management block 30, the video frame temporary storage / management block 30 transmits the video frame to the terminal storage 40 to be stored.

Then, the terminal storage 40 provides a function of storing the purchased video frame while being controlled by the video frame temporary storage / management block 30. The stored video frames can be used as a start screen of a personal terminal.

Meanwhile, there may be a slight time difference (for example, 0.5 to 2 seconds) between when a specific video frame is output to the screen and when a user inputs a video frame capture command when the specific frame is output. In this case, the specific frame that the actual user wants to capture is already gone, so the next unintended frame may be captured.

Thus, in another embodiment of the present invention, some buffers or storage devices (not shown) are placed in or after the video output block 20 for a predetermined time period (e.g., about 3 By saving the video frame in seconds, the point in time (e.g., 0.5 seconds, 1 second, 2) ahead of the user entering the video frame capture command together with the corresponding video frame at the time the user enters the video frame capture command Corresponding video frames) may also be implemented to be delivered to the video frame temporary storage / management block 30.

FIG. 2A is a flowchart illustrating an example of a video scene storage / management process of a video scene storage / purchasing method in a digital broadcast receiving apparatus according to the present invention, wherein a user selects a video frame (scene) and temporarily stores / manages it. It shows the flow of.

First, a video stream is received (200). That is, a receiver (not shown) of the digital multimedia broadcasting (DMB) terminal receives the digital multimedia broadcasting signal.

Thereafter, the received video stream is decoded (decoded) (201). That is, the video decoding block 10 decodes the video stream from the digital multimedia broadcasting signal received by the receiver. As described above, the decoding of the video stream in the digital multimedia broadcasting signal is generally performed in a conventional digital multimedia broadcasting (DMB) receiving terminal.

Thereafter, the decoded video signal is output to the screen (202). That is, the video output block 20 outputs the video stream decoded by the video decoding block 10 to the user. In this case, a user may input a signal (video frame capture command) to store a desired video scene as if the user presses the shutter of the digital camera while watching the digital multimedia broadcasting.

While outputting the video signal as described above, it is determined whether there is a video frame capture command by the user because there is a video frame preferred by the user (203). Here, the user's preferred video frame will be a scene that the user instantly likes while watching a digital multimedia broadcasting (DMB) program.

As a result of the determination 203, if the video frame capture command does not exist, it is determined whether the program is the end (205). If the end of the program is terminated, the entire process is terminated. "Process and repeat the following process.

On the other hand, if there is a video frame capture command, the determination result 203 temporarily stores / manages the video frame at the time when the video frame capture command is input (204), and proceeds to step “205”.

FIG. 2B is a flowchart illustrating a video scene purchase process of a video scene storing / purchasing method in a digital broadcast receiving apparatus according to the present invention, and purchases and stores a video frame to be purchased from temporarily stored video frames (scenes). The flow of the process is shown.

First, the user supports the user to search the temporarily stored video frame at the desired time remaining time, so that the user checks whether there is a video frame to purchase (210). That is, after watching the broadcast, the user searches for and selects a video frame to purchase from among video frames temporarily stored at a desired time.

Thereafter, the user checks whether there is a video frame to purchase (211).

As a result of the check 211, if the desired video frame does not exist, the user confirms whether to end the purchase process (214), and if the user wants to proceed with the purchase process, the process proceeds to the “210” process and repeats the subsequent process. The purchase process is complete.

On the other hand, if the check result 211, if there is a video frame that you want to purchase to pay for the video frame through the payment (212). That is, according to a known payment / payment procedure, a video frame desired to be purchased is purchased from among the temporarily stored video frames.

Thereafter, after storing the purchased video frame (213), the process proceeds to "214". The stored video frame is used as a start screen of a personal terminal.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

As described above, the present invention may allow a user of a digital broadcast receiving terminal to temporarily store a specific frame desired while watching a digital broadcast, and then pay the cost and purchase the user at a desired time.

That is, the present invention temporarily stores the video included in the digital multimedia broadcasting stream frame by frame at the moment desired by the user, and then selects the desired frame at the desired time after the broadcast and pays an amount to purchase and store the video. can do.

Therefore, through the present invention, a user can obtain a desired video scene (frame) while watching a video even without purchasing the entire program provided through digital multimedia broadcasting.
