Playing back video content including a video and partial area information representing a partial area of the video;
And outputting output to the display unit an image of the entire region at the time of reproduction start, an image of the area specified by the partial area information after a predetermined time has elapsed on the display unit,
It is characterized by including.

図７は実施例２に係る映像再生装置の構成の一例を示すブロック図である。図７に示すように、本実施例に係る映像再生装置は、アンテナ７０１、情報取得部７０２、信号分離部７０３、映像再生部７０４、メタデータ処理部７０５、領域変更部７０６、制御部７０７、タイマ７０８を有する。これらの機能は実施例１と同様である。図７の例では、映像再生装置は、さらに、描画部７０９、合成部７１０、解像度情報取得部７１１、記憶部７１２を有する。そして、本実施例に係る映像再生装置は、表示可能な最大解像度が１０８０ｉである外部表示部７１３に接続されている。外部表示部７１３は、実施例１の表示部１０７と同様のため説明は省略する。 FIG. 7 is a block diagram illustrating an example of the configuration of the video reproduction apparatus according to the second embodiment. As shown in FIG. 7, the video playback apparatus according to the present embodiment includes an antenna 701, an information acquisition unit 702, a signal separation unit 703, a video playback unit 704, a metadata processing unit 705, an area changing unit 706, a control unit 707, A timer 708 is included. These functions are the same as those in the first embodiment. In the example of FIG. 7, the video playback device further includes a drawing unit 709, a combining unit 710, a resolution information acquisition unit 711, and a storage unit 712. The video playback apparatus according to the present embodiment is connected to the external display unit 713 whose maximum displayable resolution is 1080i. Since the external display unit 713 is the same as the display unit 107 of the first embodiment, description thereof is omitted.

ステップＳ８０６では、制御部７０７が、再生する映像コンテンツの番組情報と、記憶部７１２に記憶される番組情報とを比較し、再生する映像コンテンツが過去に再生されたことがあるか否かを判断する。具体的には、再生する映像コンテンツと過去に再生された映像コンテンツの番組名および番組に関する説明を比較することにより、再生する映像コンテンツが過去に再生されたことがあるか否かを判断する。再生する映像コンテンツが過去に再生されたことがあると判断された場合には（ステップＳ８０６：ＹＥＳ）、ステップＳ８１０へ進む。再生する映像コンテンツが過去に再生されたことがないと判断された場合、即ち、再生する映像コンテンツが初めて再生する映像コンテンツである場合には（ステップＳ８０６：ＮＯ）、ステップＳ８０７へ進む。 In step S806, the control unit 707 compares the program information of the video content to be reproduced with the program information stored in the storage unit 712, and determines whether or not the video content to be reproduced has been reproduced in the past. to decide. Specifically, it is determined whether or not the video content to be played has been played in the past by comparing the program name of the video content to be played back and the description of the video content played back in the past and the explanation about the program. If it is determined that the video content to be played has been played in the past (step S806: YES), the process proceeds to step S810. If it is determined that the video content to be played has not been played in the past, that is, if the video content to be played is video content to be played for the first time (step S806: NO), the process proceeds to step S807.
