摘要： A data processing method is disclosed which involves storing on an optical disk main line data as video data and low-resolution data, the latter data corresponding to the main line data but having a lower resolution and a smaller data amount than the main line data. The main line data and low-resolution data are read and decoded individually. The decoded result of the low-resolution data is selectively output until preparations for outputting the main line data are found completed. Once the preparations for outputting the main line data are complete, the decoded result of the main line data is output selectively.

摘要： The application describes a technique of synchronizing a digital video signal for transmitting it in the uncompressed form via a synchronous hierarchy network having its internal clock, by standard frames of the network. The technique comprises steps of obtaining the video signal as a Serial Digital Interface (SDI) signal having its initial video clock and presenting a succession of video frames, storing said video signal, using the video clock, in a buffer memory having capacity of one or more complete video frames, reading said video signal from the buffer memory using a transport clock derived from the internal clock of the synchronous hierarchy network.

摘要： A direct sequence spread spectrum approach to wireless video transmissions is utilized. This approach provides a lowered spectral power density and also can provide scrambling of the video signal. By providing lower spectral power density the transmitter portion of the invention can operate at higher radio frequency output power levels while remaining in compliance with government regulation for unlicensed use. For example, in the United States, the Federal Communications Commission Part 15 rules allow for higher total conducted output power as long as the spectral power density is limited to null8 dBm for any 3 KHz bandwidth within the allocated band.

摘要： A digital video interface device interfaces a digital video signal transmitted from a first, source, digital video processing device to a plurality of second digital video processing devices. The digital video interface device receives a digital video signal having a transition minimized differential signaling (TMDS) format, translates the received digital video signal to a second signaling format, buffers the translated digital video signal to produce a plurality of substantially identical buffered translated digital video signals, and translates each of the plurality of substantially identical buffered translated digital video signals back to the TMDS format. The digital video interface device includes a first translator receiving a TDMS digital video signal and translating the received TMDS signal to a second signaling format, a buffer receiving the translated digital video signal and outputting a buffered translated digital video signal, and a second translator translating the buffered translated digital video signal back to the TMDS format.

摘要： An in-car video system with inputs for one or more analog or digital video cameras, one or more of which may be wireless, and having inputs for one or more microphones, one or more of which may be wireless. The system includes circuitry to digitize the input signals, if necessary, merge the data with system status data and compress the resulting data with any algorithm, preferably MPEG 4. A digital data cassette recorder records the compressed data, and a decompression circuit and active matrix display and audio channel provide monitoring capability of live video and audio. In some embodiments, a hard disk continuously records all data and archives previously recorded data to tape when so ordered to provide after-the-fact recording capability. In some embodiments, anti-tampering circuitry renders the recorded data tamper-proof, and a local playback circuit allows local playback of either live or previously recorded video.

摘要： Video signals input from a video input/output section are sequentially recorded on a magnetic tape section. Desired procedure information is selected from a plurality of pieces of procedure information each of which is stored in a digest video procedure storage section and defines image information capture start timing and capture time in the recording process. A capture section acquires a video signal in accordance with the capture timing and capture time of the selected procedure information and stores the video signal in a digest temporary storage section as a digest video signal. After video signal recording is ended, the digest video signal is recorded on the magnetic tape section.

摘要： In recording audio information, an information medium in a format obtained by expanding the RTR (recordable/reproducible DVD) standard is used. For management information about each piece of information recorded on the information medium, an nullaudio information cellnull is defined as a playback unit even for audio information as in the RTR standard. To a PGC (program chain) higher in level than the cell, nullplayback sequencenull information about the relationship between other video information (movie cells) and/or still picture information (still picture cells) is given.
