In this case, the television 100 generates a control signal for executing the electronic album program and transmits it to the computer 300 through the Anynet, and the computer 300 responds to the control signal received from the television 100 in response to the electronic album. Run the program.

Next, the television 100 generates a first image data request command for requesting the first image data (step S520). The television 100 sends the first image data request command to the computer 300 via the Anynet cable 400. The process of generating the first image data request command in the television 100 will be described in detail with reference to FIG. 4.

Subsequently, the computer 300 converts the compression method of the first image data into a compression method suitable for the television 100 using the electronic album program (step S530). The computer 300 transmits the converted first image data to the television 100 through the Anynet cable 400. Here, the computer 300 generates transmission data including the first image data according to the Anynet protocol using an electronic album program. Accordingly, the computer 300 may provide the first image data to the television 100 via Anynet.

Next, the television 100 extracts first image data from the received transmission data and displays an image corresponding to the first image data (step S540). A process of outputting the first image data on the television 100 will be described in detail with reference to FIG. 6 to be described later.

Accordingly, the television 100 may receive and display first image data embedded in the computer 300 using Anynet without having to include a removable storage medium or additionally a USB port and a USB cable. . Accordingly, since the television 100 may provide the electronic album service using the first image data, the television 100 may improve user convenience and service quality.

On the other hand, the television 100 displays a video corresponding to the video signal (step S550). Here, the video signal may be a broadcast signal received from the antenna 200 or may be a video signal provided from a video cassette recorder (VCR) or a digital video disk (DVD) player connected to the television 100. have.

Subsequently, the television 100 pauses the moving image according to a user's operation and detects second image data corresponding to the still image (step S560). The process of detecting the second image data in the television 100 will be described in detail later with reference to FIG. 7. The television 100 transmits the second image data to the computer 300 via the Anynet cable 400.

Then, the computer 300 displays an image corresponding to the second image data (step S570). A process of displaying the second image data in the computer 300 will be described in detail with reference to FIG. 8 to be described later. As a result, the computer 300 may display a still image of the moving picture being displayed on the television 100, and thus may provide various electronic album services to the user.

Referring to FIGS. 1 and 4, first, the controller 150 generates a control signal to display an electronic album menu on the image display unit 135 in response to an input signal received from the input unit 145 to display the OSD processor 130. To provide. Subsequently, the OSD processing unit 130 generates an OSD signal corresponding to the electronic album menu and provides it to the image display unit 135, and the image display unit 135 displays the electronic album menu (step S521).

FIG. 5 is a diagram illustrating an example of a screen displaying an electronic album menu in the image display unit illustrated in FIG. 1.

Referring to FIG. 5, the image display unit 135 displays the electronic album menu PM in an OSD menu manner. The electronic album menu PM includes a photo file open menu M1 for searching for image data to display an image, background music M2 for searching for voice data to be output from the voice output unit 140 together with the image, and the like. .

Referring back to FIGS. 1 and 4, following step S521, the controller 150 selects a photo file open menu M1 from the electronic album menu PM (see FIG. 4) according to a user's operation. It is determined whether a menu for requesting first image data stored in 300 is selected (step S522).

Subsequently, when a menu for requesting first image data embedded in the second memory 160 is selected in operation S522, the controller 150 may select the first image data selected according to a user's operation from the second memory 160. Extraction (step S523).

In operation S522, when a menu for requesting first image data stored in the computer 300 is selected, the controller 150 generates a first image data request command (operation S524).

Subsequently, the communication unit 115 transmits the first image data request command to the computer 300 through the Anynet cable 400 under the control of the control unit 150 (step S525).

6 is a flowchart illustrating a process of displaying first image data shown in FIG. 3.

Referring to FIG. 6, first, the communication unit 115 receives first image data from the computer 300 through the Anynet cable 400, and the control unit 150 receives the first image data received through the communication unit 115. Is stored in the first memory 155 (step S155).

Subsequently, the controller 150 provides the first image data to the first image processor 120, and the first image processor 120 decodes the first image data and provides the first image data to the image display unit 135. The image display unit 135 displays an image corresponding to the first image data (step S543). Here, the image corresponding to the first image data is any one of a photo, a video, and an image generated using a program for generating an image.

As such, the television 100 may receive image data from the computer 300 through Anynet to provide an electronic album service. Accordingly, the television 100 may improve user convenience and service quality.
