摘要： In a video signal recording/reproducing apparatus for emphasizing an input video signal, recording by adding an additional signal necessary for recording, and de-emphasizing when reproducing, the emphasis processing is stopped on the time axis in a period in which the additional signal is to be added. Besides, by adding an additional signal before emphasis processing, the waveform deterioration in the end portion of the effective period occurring due to addition of additional signal after emphasis processing is decreased, and a favorable waveform reproduction is realized over the entire period of effective portions.

摘要： Conventional serial bus of IEEE 1394 can not manage a transmission bandwidth and transmission channel for a future time. Therefore, it is not possible to make a reservation for recording from a STB to a VCR connected to the bus. The present invention makes it possible to perform a reservation management of the bus by defining and utilizing registers on CSR space for managing reservations of transmission bandwidth and transmission channel from present time to a future time.
In order to achieve the objects, a serial bus control apparatus of the present invention includes a means for providing a table for controlling a serial bus which has a function for securing a transmission bandwidth for the packet to the serial bus. The table is a reservation control table at least indicating a reservation of a transmission bandwidth and a transmission channel which is required from time T1 until time T2, the reservation control table is stored and controlled on a first register assigned to an address space which is accessible for reading and writing from an arbitrary node on the serial bus. The serial bus control apparatus of the present invention preferably includes a first detection part to detect that the present time is the time T1, the time T2, or the time between T1 and T2. Moreover, the serial bus control apparatus of the present invention preferably includes a rewriting part for rewriting a second register and a third register assigned to a particular address space for a particular node on the serial bus, which second register indicates the available transmission bandwidth at present time and which third register indicates the utilization status of the transmission channel at present time. The particular node on the serial bus is a node, which belongs to the serial bus control apparatus, and a node which includes the second register and the third register control apparatus of the present invention. The serial bus control apparatus of the present invention preferably includes a register providing part for providing a register for reservation control table which table is accessible for reading and writing from an arbitrary node of an arbitrary bus of the N piece of serial buses having the same standard time. In accordance with the present invention, a reservation management for future time using a serial bus for securing the transmission bandwidth and transmission channel according to IEEE 1394 can be achieved, which is not possible with conventional technology. Moreover the serial bus control apparatus of this invention is compatible with conventional systems.
