Title: Correction system for sample time difference of digital controller
Inventor: AKIYAMA MINORU
IPC: G06F3/05
Filed: 1988-12-22
Abstract: PURPOSE:To obtain a control system which is free from the influence of the time difference by using the output of a 2nd subtractor which performs the subtraction of the output of a multiplier as the input to an arithmetic process mechanism. CONSTITUTION:A signal memory means 12 stores the output of an A/D converter at every sample time point. A 1st subtractor 13 subtracts the sample value 1b preceding the output of the A/D converter, i.e., the output of the means 12 from the sample value 1a obtained at the present sample time point of the output of the A/D converter. A time difference ratio production means 14 produces and holds a time differential 1c equal to the value deltan/T from a sample period T and a delay deltan. A multiplier 15 performs the multiplication between the output of the subtractor 13 and the ratio 1c, i.e., the output of the means 14. Then a 2nd subtractor 16 subtracts the output of the multiplier 15 from the value 1a. The output of the subtractor 16 is used as the input to be applied to an arithmetic process mechanism. Thus it is possible to estimate the input signal at an ideal sample time point.

IPC: H04N5/44
Filed: 1987-12-23
Abstract: PURPOSE:To prevent the video recording from being interrupted on its way even if there is a change in the broadcast time by assigning a code to each program, comparing a code sent from a broadcast station with a reservation data at the start of program, starting the video recording in the case of coincidence and terminating the video recording by the end code. CONSTITUTION:Every time a program code is received from a broadcast station 1, a scanner 5 sends the code to a reservation video recording control section 9, which gives an instruction of video recording to a video recording section 8 only when the code is coincident with the reservation program code. Scanners 6, 7 scan other reservation channels during the video recording, and in the reception of a new program code from other scanners 6,7, the reservation video recording control section 9 gives higher priority the succeeding code to switch the channel. When the video recording end code is received from the channel during the video recording, the section 9 gives an instruction to the video recording section 8. Thus, even when the broadcast time is subject to change, the reservation video recording is attained.
