Abstract
The present invention is applied to a video camera using an optical disk based on the DVD system. Data for determination changing each time data corresponding to a recording unit from a start of a recording operation until the end of the recording operation is generated based on management data recorded in a recording medium and is recoded in the recording medium 5. A type of a recording apparatus having recorded a recording unit recorded last is determined by comparing the data for determination recorded in the recording medium 5 to the management data, thereby switching a management unit.
Claims6
A recording apparatus capable of generating management data so that a system stream with an audio stream and a video stream multiplexed therein can be managed as one recording unit from a recording start to a recording end corresponding to the recording start and also a plurality of recording units can be managed as another management unit, and also recording the system stream and management data,
- characterized in that data for determination changing each time data corresponding to said recording unit is recorded in the recording medium is generated based on the management data and is recorded in the recording medium;
- said data for determination recorded in the recording medium is compared to the management data to determine a recording apparatus having the recording unit for data recorded last, and said management unit is switched according to a result of said determination.
A recording method for a recording medium enabling generation of management data so that a system stream with an audio stream and a video stream multiplexed therein can be managed as one recording unit from a recording start to a recording end corresponding to the recording start and a plurality of recording units can be managed as another management unit, and recording said system stream and said management data in a recording medium, said method characterized in that it comprises the steps of:
- generating data for determination changing each time said recording unit is recorded in said recording medium based on said management data and recording said data for determination in said recording medium;
- and
- determining a recording apparatus having recorded said recording unit recorded last by comparing said data for determination recorded in said recording medium to said management data and switching said management unit based on a result of said determination.
A program for a recording method for a recording medium for making a computer controlling operation of a recording apparatus execute a prespecified sequence of processing steps,
- wherein said processing sequence is executed for generating management data so that a system stream with an audio stream and a video stream multiplexed therein can be managed as one recording unit from a recording start to a recording end corresponding to the recording start and also a plurality of recording units can be managed as another management unit, and also for recording the system stream and management data in a recording medium, said sequence characterized in that it comprises the steps of:
- generating data for determination changing each time said recording unit is recorded in said recording medium based on said management data and recording said data for determination in said recording medium;
- and
- determining a recording apparatus having recorded said recording unit recorded last by comparing said data for determination recorded in said recording medium to said management data and switching said management unit based on a result of said determination.
