Title: Magnetic recording and reproducing device of rotary head type
Inventor: KIKUTANI SATOSHI
IPC: H04N5/93
Filed: 1978-10-11
Abstract: PURPOSE:To generate video and sound signals recorded on a slow-run tape without causing a step-out, by outputting a reproduced sound signal with delay corresponding to an interval between sound recording and reproducing heads. CONSTITUTION:On magnetic tape 1, video and sound signals are recorded at the same time by rotary magnetic head 2 and sound recording head 19. The video signal, recorded on this tape 1, is reproduced by head 2 and the sound signal, on the other hand, is reproduced by reproducing head 18 provided distance DELTAl behind head 19 in the run direction of tape 1 and then outputted by way of delay circuit 31 of delay time determined in accordance with distance DELTAl and the run speed of tape 1. Therefore, the reproduced video signal and sound signal are synchronized each other as well as recording without reference to the tape speed, so that even when the tape run speed is reduced for high-density recording, video and sound signals with simultaneity can be reproduced.

Title: Encoder and decoder for moving compensation frame for color television signal
Inventor: HIRANO AKIRA
IPC: H04N11/04
Filed: 1981-08-12
Abstract: PURPOSE:To perform efficient encoding and decoding, by estimating a moving vector at chroma signal parts with time compression from a moving vector detected at luminance signal parts and obtaining a forecasting signal from both vectors. CONSTITUTION:An NTSC color television signal of AD-conversion is inputted to a sequence converter 201 via an NTSC/TDM conversion circuit 200. The output of the converter 201 is given to a delay circuit 203 and a vector detector 211. A subtractor 205 takes the difference between a delayed signal and a forecast signal from a line 216. This difference is multiplexed at a multiplexer 220 together with a moving vector from an encoder 218 through a quantizer 207 and an encoder 209. On the other hand, the moving vector of luminance signal parts is applied to a vector operator 250 to estimate the moving vector of chroma signal parts and is given to a variable delay circuit 256. Thus, the extension in the moving vector detection error to chroma signals can be prevented, allowing to encode color television signals with good efficiency.
