Abstract: A content can be recorded for certain in a video recording system including a video recording apparatus and a video recording and transmitting apparatus. The video recording apparatus includes: a recording control unit that starts recording the content when a period of time indicated by scheduled recording information starts; and a message transmitting unit that transmits recording-state information to the video recording and transmitting apparatus at regular intervals. The video recording and transmitting apparatus includes: a recording-state monitoring unit that determines whether or not the continued reception of a signal has been suspended during the period of time; and a recording control unit that starts recording the content when the recording-state monitoring unit determines that the continued reception of the signal has been suspended.

Abstract: Provided is a recording and playing system that prevents, even when a client terminal having no recording function receives emergency information, missing out on a program viewed with the client terminal. The system includes a server terminal and a client terminal connected to each other via a network. From among a plurality of broadcast contents, the server terminal receives a portion of a broadcast content that is broadcast after an instruction to perform recording is received. It transmits the portion to the client terminal as a recorded content. The client terminal detects start and finish of reception of the emergency information, and during the emergency information reception, notifies the user of the emergency information.

Abstract: A playback device according to the present invention has a function of supporting application development. The playback device acquires, via a network, file system information of a recording medium storing an application and mounts the acquired file system information to file system information of a recording medium equipped in the playback device. A playback control engine executes playback of an AV content that is accessible in the file system resulting from the mounting. A platform unit executes the application that is accessible the file system resulting from the mounting. When executing the application, the platform unit transmits an execution log to a debugging device that is for debugging the application to support the application development.

Abstract: Disclosed is a digital broadcast receiving apparatus for informing a user that multi-channel broadcasting of a plurality of programs is scheduled to start, prior to the start of the multi-channel broadcasting. The digital broadcast receiving apparatus receives and executes an application that a broadcast station transmits a predetermined time period (five minutes, for example) before the start of multi-channel broadcasting. In accordance with the application, the digital broadcast receiving apparatus displays a listing of preview images of the programs.
