VIDEO PLAYER-RECORDER WITH NON-LINEAR MARK LENGTH MODULATION
VIDEO PLAYER/RECORDER WITH NON-LINEAR MARK LENGTH MODULATION In a video disk system a mark along a record data track is modulated in length to represent multi-bit binary code blocks of a first length (such as three or four bits) and the player system associated with the disk operates in multi-bit co...

| description | VIDEO PLAYER/RECORDER WITH NON-LINEAR MARK LENGTH MODULATION In a video disk system a mark along a record data track is modulated in length to represent multi-bit binary code blocks of a first length (such as three or four bits) and the player system associated with the disk operates in multi-bit code blocks that axe generally longer (for example eight bits) so that two marks on the disk may represent a single code block in the associated system. The bits of the code block in the associated system are assigned to bit positions of the appropriate number of marks on the disk in a way that minimizes the effect of errors in the operation of initially writing or subsequently reading a mark. The increments of mark length are also made non-linear to further minimize the effect in the associated system of errors in mark length. PO9-78-023 |
