摘要:
When a magnetic track is formed, the magnetic track is divided into a plurality of track areas in its longitudinal direction. Information signals are recorded in the divided track areas independently of each other. At a portion of the magnetic track, there is provided a reference track area in which a specific reference signal is recorded. When an information signal is recorded in either of the track areas, the reference signal is played back from the reference track area, and the information signal is recorded in the track area corresponding to the information signal using the played back reference signal as a reference for timing of the recording.With the described arrangement, when a plurality of information signals are recorded in a plurality of track areas, which are formed by dividing a track in its longitudinal direction, independently of each other, a signal recorded in a track area is prevented from adversely affecting another signal recorded in a neighboring track area.

Encoding parameters of picture and higher layers of importance to a number of applications, and encoding parameters of slice and lower layers of no importance to all applications are converted into auxiliary packets inserted respectively into a V-blanking area and an H-blanking area of a video-data signal output by a history-information-multiplexing apparatus employed in a video-decoding system. On the other hand, a video-encoding system extracts back the auxiliary packets superposed on the V-blanking area and the H-blanking area from an input base-band video signal. As a result, a technique of superposing information on data can be changed in accordance with the importance of the information and required information can be fetched with ease.
摘要:
In a signal processing apparatus having a plurality of signal processing circuits where predetermined data is to be output sequentially through the plurality of signal processing circuits, when signal processing is performed at each signal processing circuit, timing necessary for respective signal processing is added to the data to be transmitted, as a header information, so that a complicated construction, such that a circuit for obtaining timing necessary for signal processing is added at each signal processing circuit, can be avoided, and the data can be securely processed and delivered at each signal processing circuit.

An information data recording apparatus includes a DCT (discrete cosine transform) circuit (3) for processing a video signal in a DCT fashion, a quantizer (4) for quantizing an output signal of the DCT circuit (3), outer code circuits (5) and (10) for adding an error correction code to quantized data from the quantizer (4), and a recording head (13) for recording output data on a magnetic tape (14), whereby a high frequency component of data or outer code is recorded on first and last tracks of tracks of one field. Of the tracks constructing one field, a high frequency component of data or outer code that is less affected by a reproducing error is recorded on respective end tracks that have the large possibility that original recorded data will be broken by a mis-tracking upon editing. Therefore, even when an edit point is displaced by the mis-tracking upon editing so that the original recorded data is broken to cause an error to occur, an amount that a picture quality of a reproduced picture is deteriorated when the error occurs can be reduced considerably.

摘要:
A digital signal transmission device for reproducing plural channel informational data from a digital signal formed of plural channels of informational data accompanied by channel identification data for identifying the channels in which the informational data is to be processed the digital signal having been transmitted through a single transmission line. Identification data conversion means converts channel identification data from the form which accompanies the digital signal to a modified form that identifies different channels in which the informational data will be processed.

摘要:
A ferroelectric memory includes a base member, a first dielectric layer formed above the base member, a second dielectric layer formed above the first dielectric layer, a contact hole that penetrates the first and second dielectric layers, a plug formed in the contact hole, and a barrier layer formed above the plug, and a ferroelectric capacitor formed from a lower electrode, a ferroelectric layer and an upper electrode successively laminated in a region including above the plug. The second dielectric layer has a property that is more difficult to be polished than the plug and the first dielectric layer.
