Apparatus and Method for displaying Record list in Digital Broadcasting Receiver}

The present invention displays a list of recorded programs of a PVR composite device, which records and reproduces a broadcast signal as a digital signal, with a thumbnail image, so that the TV screen is minimized and the user performs many functions with minimal remote control operation. The present invention relates to a method and apparatus for displaying a recording list in a digital broadcast receiver.

Recently, the terrestrial receiver has become more complicated and various products are released according to the trend of widespread and advanced. Recently, the most popular topic is the personal video recorder (PVR).

PVR is a personal digital video recording device that records and plays back information on a hard disk. Unlike a VCR that stores video signals on a magnetic tape, a PVR is a new concept of digital recording device that records and plays back information on a hard disk. It is a next-generation recording device that can record a certain amount of broadcast programs depending on the capacity without a VCR through the hard disk drive built into the set-top box or television body.

When the PVR selects a channel, the signal currently broadcasted on the hard drive is digitally stored and played simultaneously. Therefore, if the stop button is pressed and the play button is pressed again, the stored broadcast signal is played again from the point where it was stopped. You can also watch the program that's currently being broadcast, play it back in slow motion, or skip the boring part, making it easy to find and edit the part you want.

Hereinafter, a screen for displaying a list of programs recorded in the PVR will be described.

1A to 1C are diagrams illustrating a recording list having only a conventional string.

1A to 1C, a list of recordings and some additional information are displayed using text only, and a user selects a desired item to perform a desired operation such as playback or deletion. However, the operation of the remote control for the desired task and the scenario for the desired task are complicated.

If you want to see the detailed information of items 1 to 5 and delete the desired item, you need quite a lot of remote control operation. That is, in order to operate a command desired by a user, select up and down arrow keys, and then select a confirmation key. The detailed menu is then displayed. In the displayed detailed menu, the user selects a desired operation and then presses a confirmation key. Then, an operation desired by the user is performed, and when an operation end key is selected, the operated menu ends. Then if you want to select a different list, repeat the above process.

For example, when the user selects a 'mermaid girl' using the left and right arrow keys and selects a delete command from the command menu, a screen as shown in FIG. 5C is displayed. If the user wants to delete the selected 'mermaid', the user selects 'yes' to delete the selected 'mermaid'. In such a state, when the user scrolls the left and right arrow keys and selects 'fall of New York', the operation command maintains the selected delete command. Therefore, after deleting the 'mermaid girl', the user can also delete 'fall of New York' using only the left and right arrow keys.

Here, the item of the horizontal axis and the vertical axis can be changed.

As described above, the user selects a thumbnail of a desired program by using the left and right arrow keys and presses the confirmation key to play the thumbnail. For the non-playback operation, the detailed operation command menu appears only when the down arrow key is selected so that the OSD hides the user's TV screen to a minimum. The operation command menu selects a desired operation with the up and down arrow keys. In this case, the user may use the left and right arrow keys to move to the menu of another program while using one program menu. That is, three-dimensional and independent movement of a menu and a selection item in a horizontal / vertical direction can be selected and performed in a three-dimensional manner so that a user can continuously perform the same operation while changing a program.
