A disc used for the replay and protection of phonograph records on an automatic changer is disclosed which disc has a center hole and a keyway extending therefrom allowing the disc to slide down the changer spindle when the keyway is aligned with the spindle record release lever or to remain atop the spindle when the keyway is misaligned with the release lever.

A replay appliance for recording media containing information blocks, the appliance comprising means which are independent of the contents directory for access to files and information, and which allows replay even if the contents directory or file system is damaged. The appliance includes search means for searching for a designator of a file which is to be localized in blocks of the recording medium, evaluation means for determining the designator of following bytes which indicate a number of 2...

The invention relates to a tape handling device associated with a picture-taking (recording) or reproducing (replay) device having a drive motor, a transmission gear to be actuated by the motor, a reversing device for reversing the sense of rotation of the drive consisting of the motor and gear train, and a control device likewise actuated by the motor.

Improvements to the acquisition and replay systems for direct-to-digital holography and holovision are described. A method of recording an off-axis hologram includes: splitting a laser beam into an object beam and a reference beam; reflecting the reference beam from a reference beam mirror; reflecting the object beam from an illumination beamsplitter; passing the object beam through an objective lens; reflecting the object beam from an object; focusing the reference beam and the object beam at a...

High quality replay of a streaming multimedia video segment on demand is provided. The multimedia segment may be transmitted as a stream by a server system and received by a client system over a fixed bandwidth communications path. The client system receives a base layer of the stream, decodes the base layer and displays the decoded base layer at a first quality level. The client system stores at least a portion of the base layer in a cache. When a request for replay service for the multimedia s...

This is a system to record process data only when it has changed enough to be significant to the process being controlled and monitored. Unlike conventional fixed interval data loggers it does not miss a significant event which occurs between fixed time interval data sets. Neither does it fill its memory with repetitive constant data values. The time for data recording is determined by the process behavior and not known in advance. For this reason the time at which a data set was recorded is inc...

A data recording medium and a data replay apparatus are provided for allowing an automatic return to a menu at the completion point of a replay of one content and allowing an arbitrary jump to the next or previous content during a replay of one content. An entire disk of DVD for a musical product such as karaoke is made up of a single program chain (PGC) and tunes are divided into cells. An instruction to jump to a tune selection menu is written in a cell command (cell CMD) of each cell. On comp...

A slow motion replay system comprises a data transmitting section which adds null data to picture data at every predetermined unit to make transmission data which has N (N.gtoreq.2, N: integer) times length of the picture data. A decoding section receives the transmission data and picks out the picture data from the transmitting data to decode the picture data into decoded data. The decoding section supplies the decoded data to a display N times for every frame. The display displays each frame N...

In a record and/or replay system of the type wherein magnetic tape moves in a loop about a drum which is rotated by a motor to scan transducer gaps across the tape, drum stall conditions are overcome by momentarily reversing the intended rotational direction of the motor when a command is given to rotate the drum in the intended rotational direction but such rotation does not occur because of tape sticktion on the drum.

A tape has a format of the type wherein digital video information is recorded with each frame or field disposed on a set of multiple tracks and with at least one track being intended for replay during scene search modes of operation, only the most significant bits of pixels are recorded on the search tracks.
