A data transmission apparatus for conveying proper timing information to the destination application without embedding such information in transmission data packets. Particularly, the apparatus comprises a timing component for generating and inserting additional timing information into the header at least first packet of each frame of the data stream for transmitting to a destination node. The apparatus further comprises a receiving device for extracting the additional timing information from the transmission path header and inserting the additional timing information to data packets to be sent to application. The application utilizes the added timing for processing the received data simultaneously.

A data processing system provided with: input means for inputting stream data; management information decoding means for decoding management information transmitted together with the input data; file forming means for cutting the input data at a predetermined file length and adding part or all of the management information obtained by said management information decoding means to form a file; storage means for recording the formed file; and a cutting position definer for setting a start point and an end point of cutting of the file from the input data when the file is formed or before the file is formed, wherein the file forming means cuts the input data in accordance with the set start and end points.

Data processing system, recording/reproducing device, data processing method and file management method

A plurality of digital signals having total data rates of n bit/s or less are input to a digital recording device recording digital signals having a data rate of n bit/s. The digital signals are subjected to format-conversion for the digital recording device to be recorded therein. Furthermore, signals having a data rate of n/i bit/s or less are subjected to format-conversion to be recorded i times in the digital recording device. In the case where the data rate of the digital signals to be input is n/j bit/s, the digital signals are subjected to format-conversion so that the amount of data capable of being recorded per unit time is decreased by i/j; thus, the digital signals are recorded for a long period of time under the condition that the data recording time is prolonged j times. Furthermore, when input data to be recorded on a magnetic tape at a normal data rate by using a magnetic head mounted on a rotary cylinder is recorded, the recording device of the present invention makes it possible to select a plurality of types of track angles generated by the rotation number of the cylinder, the tape traveling speed, and the like.

A plurality of digital signals having total data rates of n bit/s or less are input to a digital recording device recording digital signals having a data rate of n bit/s. The digital signals are subjected to format-conversion for the digital recording device to be recorded therein. Furthermore, signals having a data rate of n/i.sub.1 bit/s or less are subjected to format-conversion to be recorded i.sub.1 times in the digital recording device.

Method for recording digital data including a data conversion or format

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. A packet selector (16) detects the reconstructed identification signal to determine whether the recording packet is of the digital signal or of the auxiliary signal, and then the digital signal or auxiliary signal is reconstructed by a signal reconstructor (17) in the transmission format using the selected recording packet, whereby a high quality image output conforming to the transmission format used in the normal reproductions mode is also obtained during the special reproduction modes.

A reference picture signal is stored defining a plurality of image pixels of a reference picture. The input picture signal is divided into a plurality of input block signals each defining a plurality of image pixels of a corresponding input block. Decimation information is set in advance for specifying a portion to be decimated among the plurality of image pixels of each input block. Selected image pixels of each of input blocks are addressed in accordance with the block decimation information to obtain a corresponding decimated input block having an addressed subset of image pixels relative to the plurality of image pixels of each input block. An image motion associated with each input block is estimated by comparing the addressed subset of image pixels of each corresponding decimated input block with the image pixels of the reference image.
