The bookmark information is the identifier of the currently executed application, the name of the application, the locator of the current channel, the channel name, the current date / time, and the list of keystrokes entered by the user in the application to be bookmarked (hereinafter referred to as 'key list'). It includes)

The term 'channel' generally refers to a service that is a collection of digital broadcast contents, and the channel is identified through a locator. The locator consists of an original network ID (ON_ID), a transport stream ID (TS_ID), and an SVC_ID (SerViCe_ID) corresponding to the channel number of the user, and each ID is parsed from a service information table (SI table). (S301).

The application identifier refers to the organization_id and the application_id parsed from the 'Application Information Table (AIT)' (hereinafter referred to as 'AIT').

The application information received in the MPEG-2 stream consists of two parts. The first consists of the files and the data that make up the application, and the second information contains the AIT, which contains information about the application status and data transmission. do. AIT is transmitted in the form of MPEG-2 private section. The AIT contains information about which applications are currently valid and how they are started, and the identifier of each application.

The PID (packet id) for receiving the AIT is known from an Elementary Stream (ES) whose stream type is 0x05 in the Program Map Table (PMT), and the version of the AIT is the program map. This is obtained by parsing an application signaling descriptor of a table.

The application name is obtained by parsing the AIT's application name descriptor.

In addition, when the execution information of the bookmark is input from the user, the controller 113 loads the bookmark so that a specific application desired is executed and the final data desired by the user is displayed. In addition, the controller 113 may display a predetermined error message when the bookmarked application is content that is not currently provided.

When the user selects a specific channel in which the application providing the weather information is operated for storing the bookmark, the screen ① is displayed, and on one side of the screen ①, the application that is automatically executed in the corresponding channel is indicated by the identification code a.

When the user performs the key operation b1 to watch the data broadcast, a new application for displaying various menus is displayed as shown on the screen ②. While repeating this process, the user can repeat the step of selecting 'news'-> 'weather'-> 'domestic weather' to run the application that provides the desired weather information as shown in screen ④. These steps are each one application, and the connection of the steps is performed by the key manipulation by the user indicated by b1 to b3. Therefore, the user's key operation serves as link information of the application that can be displayed in a predetermined step.

The user can watch the weather information of the screen ⑤, which is a desired data broadcast, through the predetermined key input b4 while watching the screen ④. In this case, the bookmark setting command is input through the input unit 111 based on the bookmark setting guides (c, d) displayed on the screen ④ or ⑤.

As such, the bookmark setting guides (c, d) may be provided on the corresponding MHP application, but according to an embodiment, the bookmark setting command is input through the input unit 111 without separately displaying the bookmark setting guides (c, d) and the like. In this case, the OSD unit 109 may generate and display a predetermined setting guide image.

When the user executes a desired application through a predetermined key input process (S301), the controller 113 initializes a predetermined key list on the memory 103. The key list, which is one of the bookmark information, is stored in the key list (S303).

The user performs a key operation such as b4 to watch the desired data information, and the control unit 113 receives such a key input through the input unit 111 (S305).

The control unit 113 determines whether the corresponding application is terminated by the user (S307), and if not, stores a code (hereinafter referred to as a 'key code') for the corresponding key input in the key list (S309).

The control unit 113 checks whether there is a bookmark setting command from the user through the input unit 111 (S311), and there is a bookmark setting command, the corresponding key list, the identifier of the currently executed application, the name of the application, the locator of the current channel, The bookmark information including the channel name, the current date, and the time is stored in the memory 103 (S313).

If the check result of step S311, if a new key input for the execution of a new application is received without a bookmark setting command, the process of S305 to S309 is repeated.

FIG. 4 is a diagram illustrating a screen display for executing a bookmark of an MHP application according to the present invention. The control unit 113 performs the process of FIG. 3 through a screen e of a display device (not shown) according to a user's command. Display the set bookmark list.

The bookmark list displayed as 'MHP Favorites' includes channel information stored in the bookmark, application name, and storage date / time.

At the bottom of the screen (e), a user may display a guide on how to execute the bookmark, such as selecting, deleting, or editing the name. The user may input a predetermined bookmark execution command through the input unit 111 with reference to this guide.

When a user inputs an execution command of a predetermined bookmark with reference to the screen of FIG. 4, the bookmark is executed according to the method of FIG. 5 below.

5 is a flowchart provided for explaining a bookmark execution method for an MHP application according to the present invention.

When the controller 113 receives a bookmark execution command from the user (S501), the controller 113 reads bookmark information corresponding to the selected bookmark from the memory 103. The controller 113 switches to a channel having ON_ID, TS_ID, and SVC-ID with reference to the locator included in the bookmark information (S503).

The controller 113 parses the program map table PMT from the switched channel to obtain AIT information, and parses the AIT to obtain application information (S505).

The control unit 113 compares the obtained application information with the application information of the bookmark information. The controller 113 compares the application identifiers organisation_id and application_id of the AIT with the application identifiers included in the bookmark information to determine whether there is a corresponding application set as a bookmark or whether the application is the same application. This is because the corresponding application may no longer be provided (S507).

If there is the same application as a result of the determination in step S507, the control unit 113 receives and executes the bookmarked application data (S509).

After the application is executed, the control unit 113 reads the key code input by the user from the key list (S511) and processes it on the corresponding application (S513).

This process automatically launches to a specific state of the application bookmarked by the user.
