Title: Digital recording system for voice signal
Inventor: ITOI TETSUSHI
IPC: G11B20/12
Filed: 1987-12-29
Abstract: PURPOSE:To remarkably heighten a corrective capacity for a burst error by reading out and recording all of the data in sequence of row or column after applying a double Reed-Solomon code processing on four groups of data in which a voice signal is classified on a memory map. CONSTITUTION:The voice signal of right and left channels made into a digital signal is classified to an even sample group and an odd sample group at every channel, and data classified to four groups are arranged on the memory map of 40-rowX100-column, and are written in sequence of prescribed sample. Next, a double Reed-Solomon code using a Q-encode and a P-encode is added on written voice data. Thus, the data on which the double Reed-Solomon code obtained via the Q-encode and the P-encode is added is read out sequentially in such a way that the 0-th column is read out at every row following after two pairs of ident data setting sync data which supplies synchronizing reference at a leading position in a recording and reproducing system, and following that, they are read out in sequence of a first column, a second column,..., a 99-th column at every row unit, and are recorded on a magnetic recording and reproducing device.

IPC: G09G5/10
Filed: 1990-11-29
Abstract: PURPOSE:To turn the remaining white of a non-signal part on the screen to black upside down and to improve the display quality by subjecting the non- signal part to make a reverse display with a bi-directional buffer output when the signal corresponding to less data than all screen picture element number of the display element is impressed. CONSTITUTION:Vertical and horizontal synchronizing signals are impressed in a synchronizing circuit 2 and the output signal is obtained a prescribed wave form with an AND circuit. There the AND output is applied to a monostable- multivibrator circuit 3 to generate a positive puls in a period of 2.5-3 times a vertical synchronizing signal amplitude and be applied to a bi-directional buffer 6. When the positive puls is input in the bi-directional buffer 6, the input/ output terminal of the bi-directional buffer 6 becomes high impedance and the transfer of the data is stopped. During the stop period, a high level H signal is impressed on each S-RAM within a frame memory 5 and all picture memory is set at a high level and the remaining white of the non-signal part on the screen is turned to black upside down. Hence the white part generated on the lower screen turns to black upside down and the display quality is improved.
