Abstract: In one of many possible embodiments, a method is provided for controlling trick mode playback speed. Frame indices associated with video frames of a digital video stream are monitored and a Group-of-Pictures (GOP) size is determined from the frame indices. One or more trick mode play speed parameters are calculated based on the determined GOP size. Presentation of the video frames is controlled based on the calculated trick mode play speed parameters. In one embodiment, the trick mode play speed parameters include a frame-skip count (FSC) and a frame-repeat count (FRC).

Abstract: A DTV operating screen is displayed on the CRT display screen of a DTV which is the controlling apparatus of a network. In the event that the user selects the DVHS from the buttons displayed on the DTV operating screen, data corresponding to the DVHS operation screen is input to the DTV, and a DVHS operation screen is displayed on the CRT display screen 61. The user operation executed regarding the DVHS operation screen are notified from the DTV to the DVHS, so the DTV can execute control corresponding to the operations of the user, without transmitting commands for directly controlling the DVHS.

Abstract: A recording apparatus of this invention detects the state of management information, which pertains to a recording address of an image signal, and which is reproduced from a disk-like recording medium having a first area for the image signal and a second area for the management information. On the basis of the detection result, management data is reproduced from the first area of the disk-like recording medium. On the basis of the management data reproduced from the first area, the management information reproduced from the second area is modified. A modify unit records the modified management information in the second area.

Abstract: A television receiving system displays an advertisement for a future television program. If the future television program is identified as recordable, the system also displays an option to set a reminder for the advertised program and/or an option to record the advertised program on a video recorder. If a viewer of the advertisement selects the reminder option, then a reminder is programmed in the system. If the viewer selects the record option, then the system automatically programs the video recorder to record the advertised program. If the viewer has established an interactive session during a television advertisement, and has not completed the interactive session when the advertisement ends, then the current television program is paused until the interactive session is completed.

Abstract: The present invention relates to an information processing apparatus and a program for executing a sequence of processing operations including the recording of video data recorded to a first recording medium in a first format to a second recording medium in a second format without user's manual intervention. If the information processing apparatus determines that the recording time of a frame just reproduced by a predetermined reproduction device is earlier than the recording time of a frame reproduced by said reproduction device immediately before the above-mentioned frame (step S89) or an unrecorded area has been reproduced by the reproduction device for more than a predetermined period of time (step S90), the information processing apparatus stops the acquisition of the data recorded to a digital video tape reproduced by the reproduction device (step S92), thereby stopping the reproduction of the digital video tape (step S93).

Abstract: An image recording and reproducing apparatus for re-compressing and re-recording once stored data, and a method thereof. The image recording and reproducing apparatus comprises an encoder for compressing input digital image data by a first compression rate, thereby generating and outputting first compressed data, a storage part for storing the first compressed data, a decoder for expanding the first compressed data of the storage part to restore a digital image data, and outputting the digital image data, and a controller for controlling the decoder such that the digital image data output from the decoder is transmitted to the encoder, compressed by the encoder by a second compression rate into second compressed data, and stored to the storage part.

Abstract: A program capable of individually decoding video data and audio data from data storing, mixed together, the video data, the audio data, and attribute data interleaved, wherein an SYS parse routine parses data MXF_D to extract system data SYS; a PIC parse routine parses the data MXF_D to extract video data PIC and decodes the related extracted video data PIC based on system data SYS extracted by the SYS parse routine 61, and an SOU parse routine parses the data MXF_D to extract audio data SOU and decodes the related extracted audio data SOU based on the system data SYS extracted by the SYS parse routine.

Abstract: An AVClip, and a PLMark specifying a playback start position in the AVCLip, are recorded on a BD-ROM. A cue-up operation for choosing a playback start position in the AVClip is performed by three types of instructions, namely a user-skip operation, a chapter search operation, and a Link command. Among these three types of instructions, attribute information included in marker information indicates whether only a branching command operation is allowed for choosing a corresponding playback start position, or the user-skip operation and the chapter search operation are allowed adding to the branching command.

The attribute information of the AV stream is recorded in the ClipInformation, whereby the attribute information may include address information corresponding to the discontinuous point in the AV stream, information correlating the time information in the AV stream and the address information, and the time information corresponding to a characteristic picture in the AV stream. This enables a preset mark to be retrieved promptly.

Abstract: An electronic device including an image pick-up element and an image pick-up device including a recording and reproducing element are provided in which shutter sound is muted or decreased, so that the artificial electronic shutter sound is not mixed with audio signals when recording is performed and the shutter sound may not be reproduced at the time of reproduction. The shutter sound generated by the electric artificial shutter sound data unit and the shutter sound of the reverse phase stored in advance in the sound effect data unit are mixed to cancel each other after the occurrence of the electric shutter sound, and in the canceled state audio signals are recorded.

Abstract: A recording apparatus repeatedly records an image received by a tuner such that a reproduction time reaches a predetermined time, when any key provided on an operating portion or a remote control device is continuously pressed for a constant time during recording. Therefore, when a program is recorded on a recording medium, a user continuously operates any key provided on the operating portion or the remote control device, to thereby put a section on the program. As a result, the user can simply confirm the section of the program recorded on the DVD when reproducing.

Abstract: Video data of a plurality of different formats is mixedly recorded onto one disc-shaped recording medium so that they can be continuously reproduced. A clip is constructed by video data, audio data, auxiliary AV data, and time-sequential meta data which are time-sequentially associated. The data is managed by a directory structure. The data constructing the clip is collectively stored into clip directories under a directory CLPR. When the format of, for example, the video data is changed during the recording, the clip is divided at the changing position, a clip directory is newly formed, and a new clip is formed. The mixture existence of the formats among the clip directories is permitted. The mixture existence of the formats in the file stored in the clip directory is not permitted.

Abstract: The video processing device calculates evaluation levels of frame images in video data. Scene evaluation levels are then calculated from the frame evaluation levels in each scene. The playback times for the digest video of each scene are determined from the scene evaluation levels. Collections of frame image data with the playback time are extracted from each scene and are combined to produce digest video of the desired playback time.
