Reproduction device, reproduction device control method, and recording medium

A server apparatus includes a storage, an acquisition unit, and a controller. The storage stores association information that associates access information on the program processing apparatus corresponding to user identification information with the user identification information. The acquisition unit acquires the user identification information and program-specifying information that specifies a broadcast program. The controller specifies the access information on the association information from the user identification information. Then, the controller causes the program processing apparatus to perform processing regarding the broadcast program specified by the program-specifying information acquired by the acquisition unit by using the access information.

Information processing system and server apparatus

Information processing system, server device, and control program

A recording and playback apparatus capable of recording a content downloaded from a server to a recording medium, and playing back the content, includes a recording unit configured to download the content with a playback time limit from the server and record the content to the recording medium, a playback unit configured to play back the content recorded in the recording medium, and a display data generating unit configured to generate data of a list image for displaying a list of information of each of part or all of contents recorded in the recording medium. The data of a list image is generated so that, before the playback unit plays back a content with a playback time limit, the list image includes information indicating an allowed playback period of the content, and, after the playback unit plays back the content, the list image includes information indicating the playback time limit of the content.

Record-playback device

A first index corresponding to a first conversation operation and a second index corresponding to a second conversation operation are selectably displayed on a screen of a video output device. When a communicator receives a conversation request from another device, a controller determines whether the first index or the second index is selected on the screen or whether an operating member is operated. If the first index is selected, the controller performs the first conversation operation. If the second index is selected, the controller performs the second conversation operation. If the operating member is operated, the controller performs the second conversation operation.

Communication device, communication method therefor, and communication program therefor

A transmission control device generates, based on a content stream acquired from an external source, auxiliary information necessary for at least one of recording and playback of a content in the content stream and transmits a transmission target stream to an external device. The transmission target stream includes a first stream portion based on the content stream and a second stream portion based on the generated auxiliary information.

Transmission controller, reception controller, transmission control method, reception control method and transmission control program

A recording and playback apparatus capable of recording and playing back a content downloaded from a server, includes a recording unit configured to download the content with a playback time limit, stored in a server and record the content to a recording medium, an instruction receiver configured to receive an instruction for starting playback of the content, a playback unit configured to play back the content recorded in the recording medium in accordance with the instruction received by the instruction receiver, and a warning output unit configured to output warning information related to the playback time limit of the content before the playback unit stars playback of the content, when the instruction receiver receives the instruction for starting playback of the content during download of the content.

Recording/reproducing device

A recording and playback apparatus can continue the playback of a content with playback time limit, even after the playback time limit expires during the playback of the content, and does not play back the content even though an instruction receiver receives a playback instruction when the playback of the content is stopped after the playback time limit of the content expires during the playback of the content with the playback time limit. The recording and playback apparatus outputs the warning information, when the instruction receiver receives the stop instruction after the playback time limit of the content expires during the playback of the content.

Recording and playback apparatus

A recording/reproduction device is provided wherein service content having interactivity can be restored even when recorded. In recording mode, a transport stream from a receiving deviceis received and a conversion deviceconverts this to a packet-multiplexed stream in a condition suitable for recording, which is then output as a converted stream. The conversion deviceselects packets relating to a desired service from the transport stream and, of these packets, selects only packets needed for reproduction and uses these to generate a converted stream. A recording devicerecords this converted stream on a recording medium. In reproduction mode, the converted stream from recording mediumis read by means of a reading deviceand supplied to a restoration device. Restoration device, in accordance with the content of this converted stream, restores and outputs a service content signal (for example a composite signal such as NTSC). A video/image output devicereceives this service content signal and outputs video/images. These are recorded, still in packetized condition. Consequently, since recording can be achieved including the control data, recording/reproduction can be formed without impairing the functionality of the satellite broadcast provided by the control data.

Recording/reproduction device and method for digital broadcasting

A recording and playback apparatus includes a recording unit configured to download a content stored in a server and to record the content in a recording medium, an instruction receiver configured to receive a stop instruction for stopping download of the content done by the recording unit, and a controller configured to control the recording unit. The controller controls the recording unit so as to stop the download of the content when the instruction receiver receives the stop instruction for stopping download of the content, and to restart the download of the content when a predetermined time elapses in which the recording unit is in a stop state of the download.

When a program transmission apparatus divides a program into a plurality of partial programs before transmission, a program reception execution apparatus executes a partial program when the partial program has already been received, and, when the execution needs to proceed to from a present partial program to a next partial program, executes the other partial program when the next partial program has been received.

Program reception/execution apparatus that can commence execution of a machine program having only received the program in part, and a program transmission apparatus that enables such execution

A fixed form data broadcast playback apparatusof the present invention has fixed form data broadcast playback meansthat inserts predetermined data to fixed form datafrom fixed form data storing meanswith data inserting means, makes the resultant data into an MPEG transport stream by MPEG-TS meansand playbackly transmits the resultant to a digital broadcast receivervia a digital interface. This construction enables to operate the fixed form data broadcast playback apparatuseven from a digital broadcast receiver that does not have a control function to the fixed form data broadcast playback apparatus, and further, enables to unify the operability of the screen and remote controller between the digital broadcast receiverand the fixed form data broadcast playback apparatus.

Broadcast playback and/or recording apparatus

A manager or an issuer issues a participation certificate, for an ordinary user who will newly join a group formed on a network made up of specified users, on which the manager or issuer creates a digital signature by the use of a private key of the group. Members belonging to the group authenticate one another as belonging to the same group and as authorized members of the group, on the basis of their respective participation certificates.
