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.

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 information-recording apparatus and the like according to the invention, digital information is recorded in a magnetic tape according to a recording format in which two types of sync lengths exist. The recorder records digital information having a first information-recording length and digital information having a second information-recording length, which is shorter than the first information-recording length in the magnetic tape. The recorder records a CTL signal serving as a reference during reproduction of the digital information between a recording portion of the digital information having the first information-recording length and a recording portion of the digital information having the second information-recording length. A gap portion between the recording portions of digital information having different sync lengths and a recording portion of a CTL signal are utilized as a signal processing space required for carrying out error correction such as C1 correction during reproduction of the digital information.

Information-recording apparatus, information-recording method, information-reproducing apparatus, information-reproducing method, and information-recording medium

When a recording start executed in a variable-speed recording mode, at STa signal having a variable frame rate is selected on the basis of a validity signal from among image signals having a predetermined output frame rate in which the images having the variable frame rate are contained and stored in a memory. If it is decided at STthat a phase difference between a write position and a read position in the memory has reached a recording start level, the stored signal is recorded in a recording medium at ST. If it is decided at STthat the phase difference has decreased to a recording stop level, recording to the recording medium is stopped at ST. When an end operation is executed at ST, the signal in the memory is recorded in the recording medium to then end actions. The signals are selected and recorded, thus resulting in a smaller signal quantity. Further, if the variable frame rate is varied, video effects can be confirmed only by reproducing the recorded signals.

The digital information is acquired by shooting an object from the left and right at the same time. The recording apparatus comprises a recorder for recording in the magnetic tape the digital information for three-dimensional display with the digital information being alternately arranged in the left and right frames at a speed which is 'n' times as high as the speed of recording digital information on one frame for normal display and in units of an error correction configuration and an information recording format, which correspond to the digital information on one frame for the normal display.

In a data reproduction method and a data reproduction apparatus in the present invention, video data having a frame frequency of 23.97 Hz is recorded on a tape, and in correspondence with this video data, audio data having a sampling frequency of 48 kHz is also recorded on the tape. In a normal reproduction, video data having a frame frequency of 23.97 Hz is reproduced from the tape. In this case, the rate converter outputs audio data of each field without making any conversion. Contrarily, in a compatibility reproduction, video data having a frame frequency of 25 Hz is reproduced from the tape. In this case, the rate converter outputs the audio data of each field after converting the number of items of sampled data into the number corresponding to the reproduction frame frequency.

Data reproduction method and data reproduction apparatus

In a data recording method and a data recording apparatus relating to the present invention, ECC blocks using 36 product codes are recorded on 12 tracks through scanning operations performed three times. First of all, first sync-blocks each constituted by adding a C1 parity to the data string of video data constituting an internal encoding calculation data stream are sequentially recorded. When the first sync-blocks are completely recorded, second sync-blocks each constituted by adding the C1 parity to the data string of C2 parity constituting the internal encoding calculation data stream are sequentially recorded. By recording the C2 parity at one time in a later stage, the system delay can be minimized.
