Abstract

A recording and playback apparatus including a recording unit configured to download additional information of a content stored in the server to perform a preparing operation for starting download of the content, and to download the content from the server upon completion of the preparing operation to record the downloaded content in the recording medium, and a display data creating unit configured to create data of a list image for displaying information of each content in all or part of contents stored in the recording medium. The display data creating unit creates the data of list image so that a list image displayed when the recording unit is downloading additional information is different from a list image displayed when the recording unit is downloading the content.

Claims

1. A recording and playback apparatus capable of recording a content downloaded from a server in a recording medium and playing back the content, comprising:

a recording unit configured to download additional information of a content stored in the server to perform a preparing operation for starting download of the content, to download the content from the server upon completion of the preparing operation, and to record the downloaded content in the recording medium; and

a display data creating unit configured to create data of a list image for displaying information of each content in all or part of contents stored in the recording medium, wherein

the display data creating unit creates the data of the list image so that a list image displayed when the recording unit is downloading additional information is different from a list image displayed when the recording unit is downloading the content.

2. The recording and playback apparatus according to claim 1, wherein

the display data creating unit creates the list image such that the list image does not include information for a content of which additional information is being downloaded.

3. A recording and playback apparatus capable of recording a content downloaded from a server in a recording medium and playing back the content, comprising:

a recording unit configured to download a content stored in the server and including attribute data and to record the content in the recording medium; and

a display data creating unit configured to create data of a list image for displaying information of each content in all or part of contents stored in the recording medium, wherein

the display data creating unit creates the data of the list image with a plurality of contents having the same attribute data handled in one bundle, and

the display data creating unit handles content which is being downloaded and has the same attribute separately from the one bundle to create the data of the list image.

4. A recording and playback apparatus capable of recording a content downloaded from a server in a recording medium and playing back the content, comprising:

a download recording unit configured to download a content stored in the server and record the content in the recording medium as a download content;

a broadcast recording unit configured to record a broadcast program received through a broadcast wave in the recording medium as a broadcast content; and

a display data creating unit configured to create data of a list image for displaying information of each content in all or part of contents stored in the recording medium, wherein

the display data creating unit creates the data of a list image so as to display information representing the download content together with information representing the broadcast content.

5. The recording and playback apparatus according to claim 4, further comprising an instruction receiver configured to receive an instruction for designating an attribute of the content recorded in the recording medium, wherein

the display data creating unit creates the data of the list image for a content which is recorded in the recording medium and has an attribute designated by the instruction receiver.

6. A recording and playback apparatus capable of recording a content downloaded from a server in a recording medium and playing back the content, comprising:

a recording unit configured to download a content stored in the server and having additional information and to record the content in the recording medium;

a playback unit configured to play back the content recorded in the recording medium by the download;

a display data creating unit configured to create data of a list image for displaying information of each content in all or part of contents stored in the recording medium, wherein

before the playback unit plays back the content, the display data creating unit acquires a thumbnail image from the additional information of the content to create the data of the list image including the acquired thumbnail image, and

after the playback unit plays back the content, the display data creating unit generates a reduced moving image based on the content to create the data of the list image including the generated reduced moving image.

7. The recording and playback apparatus according to claim 6, wherein

the display data creating unit changes the thumbnail image into the reduced moving image in the list image when acquiring license information of the content.
