The system also has a data editing-side unit including a receiver receiving the data transmitted from the data transmitting-side unit; editing instructions for performing the final editing of the video recorded on the recording medium by using the data received by the receiver; and a final editor performing the final editing of the video recorded on the recording medium based on the editing instruction.

Abstract: The present invention is built on a time out control apparatus to control the time out when a packet is transferred between terminal units connected to different buses. In the time out control apparatus, delay measuring means measures the delay time required for a response packet to be received after a request packet is sent to a terminal unit (control unit) connected via a bus. Delay information list generating means generates a delay information list in which the delay times measured by the delay measuring means are related to the individual identification information on the respective terminal units. Information output means reads out the delay time from the delay information list in accordance with a request from the terminal unit and outputs the delay time to the terminal unit. This sets the delay time on the time out register of the terminal unit.

Abstract: A serial bus control apparatus is disclosed. The apparatus includes a device for providing a reservation control table for reserving a transmission bandwidth and a transmission channel used at a future time on a serial bus. The reservation control table is organized such that transmission of data of certain bandwidth and channel at a certain future time can be reserved for a transmission between arbitrary nodes. The reservation control table is stored and controlled on a first register. The register is accessible for reading and writing from an arbitrary node on the serial bus. The apparatus may further include a detection part to detect present time and a second and third register for securing available transmission bandwidth and channel at present time. By having this reservation control table, it becomes possible for each node on the serial bus to secure transmission of data of certain bandwidth and transmission channel in a desired future time.

Abstract: In a digital signal recording and reproducing apparatus, digital input data is transmitted in a transmission packet format and is recorded in a recording packet format. In a recording stage, an auxiliary signal generator (3) generates an auxiliary signal for special reproduction in the transmission packet format, and the digital and auxiliary signals are converted into respective recording packets by means of recording signal converters (5, 6). Recording means (9, 10) performs a specific recording process on the recording packets and an identification signal for identifying between the recording packets of the digital signal and of the auxiliary signal. While in a reproducing stage, reproduction signal processing means (14, 15) performs a specific reproduction process on the reproduction signal to thereby reconstruct the recording packets and the identification signal.

Abstract: The present invention is to provide a cooling system for cooling a strip in a vertical path of a continuous strip heat-treating process in which cooling nozzles are arranged in a width direction of a strip on the surfaces of cooling headers arranged closely opposed to both surfaces of the strip, and each cooling nozzle is inclined to both edge portions in the width direction of the strip by an inclination angle in such a manner that a center line of a jet of a cooling medium, which is jetted out from the cooling nozzle, is inclined with respect to a normal line at a position on the strip surface where the center line of the jet of the cooling medium crosses the strip.

Abstract: A recording apparatus for recording digital signals to plural tracks formed sequentially on a tape using plural heads includes a first selector for selecting the first through n track sets, continuous tracks within the plural tracks formed on the tape. A disposer disposes the first through k separated high speed reproduction data areas to the same positions in each of the m tracks comprising the first through n track sets. A first recording unit records the same high speed reproduction data to the same track position in at least the tracks having the same azimuth within the m*k high speed reproduction data areas belonging to the same track set. A second selector selects the n+1 through n+N, each track set comprising M tracks selected from among the tracks to which the high speed reproduction data areas are not disposed. A second disposer disposes a continuous very-high speed reproduction data area to the same position in each of the M tracks forming the n+1 through n+N track sets.

Abstract: Recording apparatus for recording video signal on a tape by helical scan heads has a special frame data detector for detecting a special frame data that can be processed during a reproducing operation, without any additional data, to reproduce an image, a memory for storing the special frame data, and inserting arrangement for inserting a selected track after a predetermined number of tracks. One selected track is written with a portion of the special frame data repeatedly, and another selected track is written with another portion of the special frame data repeatedly, and so on. During the high speed reproducing mode, various portions of the special frame data as obtained from a number of selected tracks are gathered to form an image.

The recording and reproducing apparatus includes: an input interface for outputting the input encoded data stream to two channels; recording processors, connected to the outputs of the input interface, for converting the input encoded data stream into a signal suitable for writing onto a magnetic tape by a recording head; a tape speed controller for varying the speed of the magnetic tape in accordance with the bit rates of the input encoded data stream; a reproducing head for reading the signal from the magnetic tape; reproducing processors for processing a reproduced signal; and an output interface. The input interface divides and outputs the input encoded data stream to both of the two channels when the bit rate of the input encoded data stream is N.sub.

Abstract: In a time-base inversion type linear phase filter, an input signal is time-base inverted, and thereafter delayed. The delayed signal is time-base inverted back to the original time sequence and then filtered by a first IIR filter. First and second selectors alternately select the time-base inverted signal and the delayed signal in opposite phases to each other. Output signals of the selectors are filtered by second and third IIR filters and then alternately selected by a third selector. An output of the third selector is time-base inverted back to the original time sequence and added to an output of the first IIR filter. A nonlinear emphasis/de-emphasis apparatus is constituted by using this linear phase filter.

Abstract: In a video signal recording/reproducing apparatus for emphasizing an input video signal, recording by adding an additional signal necessary for recording, and de-emphasizing when reproducing, the emphasis processing is stopped on the time axis in a period in which the additional signal is to be added. Besides, by adding an additional signal before emphasis processing, the waveform deterioration in the end portion of the effective period occurring due to the addition of additional signal after emphasis processing is decreased, and a favorable waveform reproduction is realized over the entire period of the effective portions.

Abstract: A signal processing apparatus for changing the frequency characteristics of an input signal, e.g.--a video or audio signal, allows a signal to pass through a transmission circuit in a positive time sequence and then, allows the signal to be transmitted through another transmission circuit having the same transmission characteristics in a reverse time sequence with respect to the positive time sequence. Also, while the transmission circuit is arranged to have a zero-phase characteristic, each segment of a continuous signal is processed throughout a period which is equal to at least two times a duration of an impulse response direction of the transmission circuit. Accordingly, unwanted wave errors appearing at discontinuous regions of the signals are eliminated.
