Video server, control apparatus, control method, and recording medium
First Claim
1. A video server which can accumulatively record a video signal reproduced by a video signal reproducing apparatus, comprising:
- communicating means for communicating with said video signal reproducing apparatus which reproduces and outputs the video signal on the basis of time information corresponding to an edition unit of said video signal;
control means for allowing said communicating means to communicate with said video signal reproducing apparatus, obtaining said time information on said video signal reproducing apparatus, and controlling said video signal reproducing apparatus so as to reproduce the video signal on the basis of said time information;
video signal processing means for performing a predetermined process on the basis of said time information to said video signal outputted from said video signal reproducing apparatus on the basis of the control by said control means; and
recording means for recording said video signal subjected to said predetermined process by said video signal processing means, wherein said control means obtains said time information on said video signal reproducing apparatus at a period longer than said edition unit.

Abstract
It is an object of the invention to reduce a load of an inquiry of a VCR about time information by a video server. For example, in response to an instruction from a host controller 105, a VCR 101 is controlled by a video server 100, a tape is reproduced by the VCR, and a video signal is outputted. The video signal is supplied to the server, encoded, and recorded. A common reference signal is supplied to the server and VCR. The server executes an encoding process while inquiring of the VCR about the time information. Upon inquiry of the VCR for the time information, the server detects a current state of the VCR and adjusts an inquiry interval of the time information in accordance with a detection result. The server presumes the time information in the VCR on the basis of a reference signal, thereby reducing the number of times of inquiry of the VCR for the time information by the server. Thus, a communication load between the server and the VCR is reduced.
