Adaptive system for selectively recording from a plurality of video sources and method thereof
First Claim
1. An adaptive video recording system for selectively recording a plurality of video signals outputted from a plurality of video sources one after another, comprising:
- a recording disc, to which at least the video signals and recording information data related to the video signals, are to be recorded in a directly accessible manner;
a recorder for recording the video signals, by a field or frame unit in a time divisional manner by use of a recording format, which is set in accordance with the number of said video sources (k) and in which a field or frame number of the video signals of each video source is expressed by {kn+(1, 2, ..., k)} on said recording disc wherein k denotes the number of said video sources and n denotes the block number of the video signals, and the recording information data, which is related to the video signals and includes information indicating the number of said video sources (k) and the block number (n), to said recording disc; and
a switcher, coupled to said video sources and said recorder, for switching and outputting the video signals from said video sources to said recorder by the field or frame unit.

9. An adaptive video recording method for selectively recording one after another at least one of a plurality of video signals outputted from a plurality of video sources and/or a plurality of video signals corresponding to a plurality of image data divided and extracted from one image data, said method comprising the steps of:
-
reading out recording information data from a recording disc, to which at least the video signals and the recording information data, which is related to the video signals and includes information indicating the number of said video sources or said divided image data (k) and the block number of the video signals (n), are recorded in a directly accessible manner, said video signals being recorded by a field or frame unit in a time divisional manner by use of a recording format, which is set in accordance with the number of said video sources or said divided image data, (k) and in which a field or frame number of the video signals of each video source or each divided image data is expressed by {kn+(1, 2, ...., k)} on said recording disc wherein k denotes the number of said video sources or said divided image data and D denotes the block number of the video signals, according to an operation indication for record start; determining a record starting address at which recording is to be started on the basis of the read out recording information data; selecting one after another the video signals on the basis of a predetermined condition; recording the selected video signals to said recording disc from the determined record starting address by use of the recording format; stopping recording the video signals according to an operation indication for record stop; and recording the recording information data related to the recorded video signals to said recording disc. - View Dependent Claims (10, 11, 12)
