  • Digital broadcast recording apparatus
    Patent number: 7558470
    Abstract: The present invention provides a digital broadcast recording apparatus which prevents an unnecessary recording in a situation where it is not possible to descramble a program or it is prohibited to record a scrambled program. The digital broadcast recording apparatus includes a descrambler that detects a channel where a descrambling-not-possible situation occurs. The apparatus also includes a service manager which terminates the recording and writes, into a management table, that a descrambling-not-possible situation has occurred during recording, when there is recording data showing that recording is being executed on the channel which is detected as having the descrambling-not-possible situation.

  • Model optimization adaptive control method
    Patent number: 6625586
    Abstract: A state of a control object is detected, the detected state of the control object is made an initial value, and a simulation with a control rule, a control gain, and an instruction signal value, which control the control object, as parameters is sequentially carried out by using an internal model expressing its own control system and by a computation method to optimize a predetermined evaluation standard, so that the control rule, the control gain, and the instruction signal value to optimize the evaluation standard are obtained and the control object is controlled.
