To make it possible to easily use video data of raw data of a high frame rate input from a single-chip camera in a server system that is different from an AV server system in which an AV server itself is included. First AV clip data is obtained by performing a compression encoding process to raw data of a high frame rate input from a single-chip camera and is written in a storage. The raw data of the high frame rate is obtained by reading the first AV clip data from the storage and processing a compression decoding process on the first AV clip data, video data of a high frame rate is obtained by performing a demosaic process on the raw data, and second AV clip data is obtained by performing a compression encoding process on the video data and is written in the storage. The second AV clip data is read from the storage and transmitted to a second AV server system that is different from a first AV server system in which an AV server itself is included.

AV server and AV server system

To increase the number of IO ports and to increase the storage amount easily. An AV server system includes: a plurality of AV servers including internet protocol (IP) input-output ports for connecting to other AV servers, the IP input-output ports being independent from input-output ports to an outside of the system; a client controller configured to control the plurality of AV servers; a manager storing information relevant to AV clip data recorded in the plurality of AV servers and AV clip data input into the plurality of AV servers; and a frame synchronization unit configured to perform frame synchronization between the plurality of AV servers.

AV server system and AV server

The present invention relates to a non-tracking VTR apparatus. The data reproducing apparatus is characterized in that, of tracks of the predetermined number serving as the editing unit, tracks of a part of the rear side are set to a pre-writing priority area and the remaining tracks are set to a post-writing priority area, with respect to each recording block reproduced from the pre-writing priority area and which is error-corrected by C1 error correction, it is determined whether or not the reproduced data of the recording block with the same ID as that of the recording block is written in the memory. The reproduced data of the recording block in which the reproduced data was not written is written in the memory and the reproduced data of the recording block in which the reproduced data was written is inhibited from being written in the memory.

Data reproducing apparatus and data reproducing method

In an apparatus for reproducing a recorded signal and the like of this invention, two reproducing heads are provided for a single track with their set positions being deviated in the track width direction. A signal selecting unit discriminates a reproducing head whose tracing condition of a target track is appropriate based on an error correction result of a C1 correcting unit and output levels of reproducing heads. A signal obtained by the discriminated reproducing head is supplied to a C2 correcting unit to generate an output signal. Consequently, an off track allowance is increased as compared with a case where the target track is traced with a single reproducing head. At the time of a special reproducing operation or even if a narrow track pitch system is adopted, a recorded signal is reproducible properly.

Apparatus and method for reproducing recorded signal

Digital data recording apparatus includes a modulator for modulating a recording clock by a recording data. A reference voltage and a reference current in signal processing are set based on a reference clock having a multiple cycle of the cycle of the recording clock when the reference clock is supplied via a rotary transformer. A demodulator demodulates a modulation signal supplied via the rotary transformer to produce a demodulation signal, from which a recording signal is generated for recording on a recording medium. The demodulator obtains a modulation signal and an inverted modulation signal from which first and second saw-tooth wave signals are produced when the reference current is supplied. A mixer mixes the first and second saw-tooth wave signals, and the demodulation signal is obtained, based on the mixer output and the reference voltage.
