Abstract: Authentication information (125) obtained by a device (100) at one level of a transformation sequence is securely communicated to another device (200) at another level of the transformation sequence. To assure that the communicated authentication information (125) is not merely a copy of previously communicated authentication information, each communication (145) includes an item (255) that the receiving device (200) can verify as having been recently generated.

Abstract: An information processing apparatus includes: a reception unit that receives multiple captured images that are captured with a capture device in parallel from an external apparatus to which the capture device that captures an object is connected; a detection unit that detects a priority image that is included in the multiple captured images being received by the reception unit and is assigned priority information that specifies the priority image to be preferentially displayed on a display device; and a controller that controls the reception unit to stop receiving other captured images which are not detected by the detection unit and to receive the priority image detected by the detection unit and controls the display device to display the priority image on the display device when the priority image is detected by the detection unit.

Abstract: The invention prevents unwanted sounds from being outputted from an AV output apparatus such as a HDTV receiver. In the invention, when a streaming signal of a predetermined format having video data and audio data is inputted to a streaming input terminal 10, separation unit 23 of a relay apparatus 2 separates this signal into the video data and audio data. HDMI transmitter 27 generates and outputs a streaming signal having the video data separated by the separation unit 23, of the same format as that of the streaming signal inputted to the streaming input terminal 10.

Abstract: A player model (1) includes an output section (10) that reads out a source packet having a transport packet and arrival time stamp from TS1 and TS2 connected seamlessly to each other and outputs the transport packet according to the arrival time stamp, and a decoder (20) that decodes the transport packet. The output section (10) inputs the transport packet according to the arrival time stamp of the source packet to the decoder (20). The decoder (20) includes an audio buffer TBn having a capacity capable of buffering the audio data corresponding to the time required for inputting I picture, which is the first picture of TS2, to a video buffer TB1.

Abstract: This invention relates to a position/orientation measurement apparatus which can measure a position and orientation while achieving both high stability and precision. An image including indices laid out on a space is captured, and the indices are detected from the captured image. When a plurality of indices are detected, their distribution range is calculated, and an algorithm to be applied in position/orientation calculations is selected according to the size of the range (S3033, S3050, S3060). For example, when the indices are distributed over a sufficiently broad range, six parameters of the position and orientation of an image capture device are calculated as unknowns (S3070). As the distribution range of the indices becomes smaller, the degrees of freedom of unknown parameters to be calculated are reduced (S3035, S3025).

Abstract: The present invention provides a moving picture data processing apparatus for outputting moving picture data by adding time information thereto, which includes: a moving picture input section which receives an input of the moving picture data for which a standard screen rate and one or more screen rates are switchable at an arbitrary timing; a time information addition processing section which adds input time information to the moving picture data; a timer section; an input start time acquiring section which acquires an input start time for the moving picture data; an input time information generating section which calculates the input time information by integrating the time information with the input start time; a moving picture playback section which plays back picture frames of the moving picture data at the standard screen rate; and a time information extracting section which extracts the input time information from the moving picture data.

Abstract: On a BD-ROM, PlayList information is recorded. The PlayList information includes MainPath information and SubPath information. The MainPath information and SubPath information include connection_condition information and sp_connection_condition information, respectively. The connection_condition information and sp_connection_condition information indicate that, when the connection state between two MainClips referred to with the MainPath information is seamless connection (CC=5), the connection state between two SubClips referred to with the SubPath information is also seamless connection (SP_CC=5). In the case of CC=5 and sp_CC=5, IN_time of PlayItem is equal to IN_time(SubPlayItem_IN_time) of SubPlayItem.

Abstract: A method to record high frame rate video, compatible with existing industry standards, that permits selecting either slow-motion playback or true speed playback with synchronized audio.

Abstract: A system comprising first input means for receiving a transport stream from an external source, second input means for receiving an input from a memory, means for connecting the first and second input means to an interface which is arranged to provide an output stream to a decoder. The second input means is arranged to provide an output to the interface in such a form that the interface does not distinguish between the output from the first and second input means.

Abstract: An image display device and an image display method are provided. The image display device includes: a signal processing unit receiving and processing a broadcasting program; a storage unit storing the broadcasting program; an outputting unit decoding and outputting the broadcasting program; and a control unit controlling a progress bar that displays a storing or playing progress state and a thumbnail image of the broadcasting program according to a progressing state to be displayed when the broadcasting program is stored in the storage unit or the broadcasting program stored in the storage unit is played.

Abstract: There are provided an information storage medium capable of real-time recording/playback of digital moving picture information, and a digital information recording/playback system using this medium. In a medium that records/plays back data including video data and control information, the control information (DA21 in FIG. 4; RTR_VMG in FIG. 30) includes information (VOBU entry in FIG. 31) for accessing a specific portion (VOBU) of the video data.

Abstract: When data of image information is compressed and is recorded on a recording medium, additional information about the image information is recorded in a conveniently usable state. There is provided read/write unit information as a unit of reading and writing the compressed image information to the recording medium. The read/write unit information contains a plurality of units of decoding and reproducing unit information that comprises one frame (or one field) of the image information. At least one piece of decoding and reproducing unit information is subject to compression encoding through the use of only image information in the decoding and reproducing unit. In the read/write unit information, there is multiplexed and recorded additional information about the decoding and reproducing unit information for a plurality of units within the read/write unit in an extractable manner separately from the compressed image information.

Abstract: A media server in a home entertainment network allows a media rendering device to act as a digital media receiver. The media server enables trick mode functions such as scan forward or reverse, slow motion, pause, and seek on rendering devices with capabilities limited to 1× playback. The media server receives commands from user input at the rendering device transmitted over the network to the media server. The media server manipulates the media stream before transmission over the network by deleting or adding frames to the media stream as necessary to emulate the desired playback functions and replacing frame timestamps to create a media stream that appears to the media rendering device as a sequential 1× stream. The transmitted media stream may not contain all of the media content stored in the corresponding media file on the media server, thus avoiding limitations on the download bandwidth and local client storage.
