Abstract: DVD-video data and DVD-audio data are recorded in a DVD-Avd disc. The DVD-audio data is composed of an audio manager having an audio manager information, an audio manager menu, a first audio title set including first audio data and a second audio title set including second audio data. The first audio data of the first audio title set is connected with audio contents included in the DVD-video data, and a real time information (RTI) pack or a still picture (SPCT) pack is included in the second audio title set. Therefore, the audio contents of the DVD-video data and the audio data of the DVD-audio data are managed by the audio manager information, and text information indicated by real time information or a still picture is displayed while reproducing the audio data. Also, DVD-video data recorded in a DVD-video disc, which is normally reproduced by using a reproducing apparatus dedicated to the DVD-video disc, can be reproduced by using a reproducing apparatus for the DVD-Avd disc.

Abstract: In the known color stripe process for preventing recording of video signals, the color burst present on each line of active video is modified so that any subsequent video tape recording of the video signal shows variations in the color fidelity that appear as undesirable bands or stripes of color error. This color stripe process is improved by a combination of modifying the phase of the color burst on only part of the color burst. Additional improvements were obtained by incorporating techniques of widening the normal color burst envelope towards the trailing edge of horizontal sync and towards the beginning of active video. These techniques are useful in improving the performance of the color stripe process in both the NTSC and PAL color systems. However, additional improvements are described in the PAL system whereby the phase modifications are controlled so as to avoid disturbing the so-called PAL ID pulse.

Abstract: A method of operating an electronic video device such as a DVD player, wherein video clock signals and audio clock signals are derived from a system clock signal using two phase-lock loops, and these video and audio clock signals are used to process encoded video data and encoded audio data, but digital-to-analog conversion of the audio data stream is controlled by the system clock signal rather than the audio clock signals. By using the system clock signal to control the audio digital-to-analog converter (DAC), the DAC avoids the poor performance issues that can arise from the jitter introduced into the audio clock signals by the PLL. The system clock signal may be divided by an integer to generate the sampling clock for the audio DAC. In the illustrative embodiment, the system clock signal has a rate which is not an integer multiple of the sample rate of the audio data stream. For example, the system clock rate might be 27 MHz while the sample rate of the audio data stream is 44.1 kHz.

Abstract: A field editing system for editing materials in a material collecting place.

Collected materials can be processed on the common disc-like recording medium from image pickup to editing.

Abstract: An AV data recording/reproducing device is connected to a digital broadcasting tuner and the like via an IEEE1394 bus, in order to realize high-speed transfer when duplicating or transporting AV data between devices such as audio-visual data recording/reproducing devices. A synchronous transfer input/output portion inputs and outputs stream data that are AV data by isochronous transfer with an MPEG-2 transport stream. A recording control portion and a reproduction control portion generate timestamped data and reproduce the stream data, and an HDD stores the timestamped data. An asynchronous transfer input/output portion asynchronously inputs and outputs the timestamped data by SBP-2 transfer. Consequently, the timestamped data that can reproduce the stream data are transferred at high speeds, regardless of an actual time required for performing the display or the like of the stream data.

Abstract: A relay appliance at a defined playing time for accessing information on recording media containing information blocks, if the recording medium has no concordance list producing a relationship between the replay time and the recording location, or the concordance list is damaged. In order to access or to replay information from a recording medium at a defined playing time, the recording medium being, for example, a Digital Versatile Disk (“DVD”) which does not include DVD Video Title Set Time Map Table, a replay appliance is provided which drives a scanning device using a binary search to a point on the recording medium which corresponds to the access point defined by the playing time. The field of application of the invention extends to replay appliances for recording media containing information blocks, such as a digital video/disc (also called a DVD).

Abstract: A hard disk recorder has a time-shift playback function of storing, on an HDD, a program which is now being received, displaying the stored program, even if program-storing is still under way, in such a manner that the program is displayed from an arbitrary section of the program among program sections that have already been stored, and pausing the display of the program or changing the display speed according to an operation by a user while the program is being watched. A control unit sets, in response to a channel-switch instruction, the HDD in a pause state from which a storing operation can immediately be started, thereafter sets the HDD in a recording-wait state to switch the channel, and sets the HDD in a playback state according to a determination that the HDD is in a recording-wait state.

Abstract: A digital signal recording apparatus for recording in blocks on a recording medium an input digital signal in the form of a plurality of input packets. Each of the input packets has a predetermined number of bytes. A first time stamp has been added to each of the input packets in advance for indicating a time of transmission of the input packet. A time stamp generator generates a second time stamp having a different format than the first time stamp added to each of the input packets in advance. A time stamp adding circuit removes the first time stamp added to each of the input packets in advance and adds the second time stamp to each of the input packets. A recording signal processor generates a recording signal in blocks from the input digital signal with the second time stamp added to each of the input packets.

Abstract: A dynamic method and system for processing video source frames (e.g., a television movie) with a video processing system (VPS) that includes a processor, a memory structure, input devices, and an output display. The video source frames, which are received by the VPS from a video source, are executed by the processor. While the video source frames are being executed, a subset of the frames, called key frames, are extracted from the video source frames and stored in the memory structure. The extracting of the key frames is implemented in accordance with a frame extraction algorithm. The extracting is terminated prior to completion of execution of the video source frames. Following termination of extracting, the key frames are reviewed by a user with the output display to determine whether to watch the remainder of the video source frames. The key frames are erased after being reviewed.

Abstract: Audio signals and video signals are recorded as follows. Three video PES packets, each being formed of one video frame, are combined to form a video editing unit. Then, the video editing unit and the associated audio editing unit are alternately disposed on a magnetic tape. The recorded PES packets are output as a TS as follows. A STC is initialized, and then, PSI packets of a PAT and a PMT are output. TS packets specially used for a PCR for storing the STC are then output at certain intervals. Subsequently, video PES packets are converted into TSs, and the output of the video TSs is started while synchronizing a time obtained by subtracting vbv_delay from the first I-picture DTS with the STC. Audio PES packets are converted into TSs, and the output of the audio TSs is started while synchronizing a time obtained by subtracting the start up delay from the first frame with the STC. Data streams are recorded in the following manner.

Abstract: Often, during an event, such as a movie, play, concert, opera, etc., viewers of the event attempt to illicitly record the event. Such illicit recording attempts may be interfered with by using emitters that emit radiation that interferes with recording and/or operation of the recording devices. For example, infrared emitters may be used to saturate an event viewing area. The infrared, while non-visible to human viewers, is received and recorded by recorders using charge-coupled devices (CCDs), such as conventional digital cameras, movie cameras, television cameras, telescopes, etc. Other radiation can be emitted based on the type of recorder with which one desires to interfere. Alternatively, or in addition thereto, emitters may also be used to send commands to recorders, such as stop, rewind, eject, etc., to interfere with operation of the recorders.
