Patent DE-2737166-A1 (DE)
Title: Synchronisation pulse separator for video signals - has binary switching stage for interface suppression
Inventor: KREMERS ERNST ING GRAD
IPC: H04N5/12
Filed: 1977-08-18
Abstract: The video signal passes through an amplitude filter (AS) to a sync. pulse separator stage. From one output (AHS) line sync. pulses pass to the horizontal driver whilst from the other (AVS) vertical sync. pulses pass by way of an AND gate (4) to a monostable. This, in turn, feeds a vertical oscillator (VO) and the frame deflection circuit. The horizontal sync. pulses are additionally fed to the and gate by way of an OR gate (0). A switch (S) feeds either a binary "0" or a binary "1" to the OR gate to enable or disable the interface.

Inventor: JANAK MILOSLAV DIPL ING
IPC: G11B20/12
Filed: 1979-06-20
Abstract: Method and apparatus for dividing a track on a magnetizable information storage disc into sectors by writing sector identification information into the track. In order to optimize the storage capacity of a track on a magnetizable information storage disc the track is first filled with information bytes in response to the occurrence of the leading edge of an index pulse (a) derived from the disc in such manner that a predetermined number of bytes fill a portion (ix) of the track, followed alternately by sector identification bytes and further bytes defining the data field of the relevant sector in portions SK and DT respectively until the final group of sector identification bytes has been written into portion SKn, followed by further bytes into portion z until the leading edge of the next index pulse occurs. The (positive or negative) difference between the total number of bytes in the portions z+ix and the number of bytes in each of the data field portions (DT) is then determined and the write operation is then repeated in the same track with the number of bytes written in the data field portions modified in accordance with the difference determined, so that the difference is distributed uniformly over the various data field portions. The write operations are controlled by apparatus comprising counters which address a read-only memory containing the information bytes, an arithmetic unit for determining the difference, and a store storing the modified number of bytes to be written to define each data field.
