Title: Picture encoding and decoding device
Inventor: TSUJIKADO MITSUO
IPC: H04N19/60
Filed: 1990-08-08
Abstract: PURPOSE:To attain prediction between moving compensating frames, and to enable encoding at a high efficiency by multiplying a local decoded picture signal by a leak coefficient, and outputting the result to the first frame memory so that the result can be stored as the predicted picture signal of the next frame. CONSTITUTION:A DCT inverter 307 inverse-transforms a reproduced conversion factor into a reproduced residual signal. The reproduced residual signal obtained by the CDT inverter 307 is turned to the local decoded picture signal after adding a picture signal (predicted value) from a frame memory 310 to it by an adder 308. A multiplier 309 multiplies the local decoded picture signal being the output of this adder 308 by a leak coefficient alpha. The output signal of the multiplier 309 is stored in the frame memory 310 as the predicted signal of the next frame. Thus, the prediction and encoding of the picture are operated in a time area so that the prediction between the moving compensating frames is attained, and the encoding can be operated at the high encoding efficiency.

Filed: 1983-11-08
Abstract: PURPOSE:To prevent unjust reception by storing an address specific to a pay television receiver to a ROM and also storing a fixed address and a logical address for the purpose of reception of a special program to a customer's RAM. CONSTITUTION:A signal transmitted from a pay television managing device is inputted to a frequency converter 8 via a directional coupler 6 and a distributor 7, and after the frequency is decreased at the converter 8, the result is fed to the television receiver via a distributor 9 and a horizontal period restoration circuit 10.
