Title: Signal system adaptor for television receiver
Inventor: ABE HIROTOSHI
IPC: H04N7/00
Filed: 1989-07-14
Abstract: PURPOSE:To improve the picture quality by processing a television signal in the moving picture mode when the television signal is inputted from a simple MUSE down-converter. CONSTITUTION:When a television signal from a simple MUSE down-converter 123 is fed via a switch 124, a movement adaptive sequential scanning conversion section 107 is set forcibly to the moving picture processing mode. The signal outputted from a selector 105 is subject to the moving picture processing mode entirely in the movement adaptive sequential scanning conversion section 107. Thus, even when black and white areas have an offset between fields, no rugged ness is caused and the range of the offset becomes a gray color.

Title: Speed transforming method using elastic stored memory
Inventor: TANAKA SHINJI
IPC: H04L7/00
Filed: 1988-07-20
Abstract: PURPOSE:To realize the simultaneous control of both writing and reading jobs with the use of an elastic stored memory of a single surface by switching the reading timing based on the collision of the read and write resetting signals. CONSTITUTION:A frequency 2-divider 2 divides a read signal into two-frequency and inputs them to an elastic stored memory 1 and a switch control means 3. When an inhibited area signal is inputted to the means 3 when a reading job collides against a writing job, the means 3 switches two outputs of the frequency 2-divider 2 and inputs the signal having its polarity inverted to a switching signal output means 4. Thus the means 4 outputs the signal having an inverted polarity to a selection means 5 to switch the read signal. As a result, the reading timing is switched and the collision is avoided between the reading and writing jobs.
