Abstract
A device for recording records digitally encoded video information on a record carrier according to a predefined recording format, such as DVD+RW. The device has a unit for gathering meta-data which describes parameters of the real-time information, and records the meta-data. The record carrier has to be compatible to existing recording devices which are not aware of the meta-data. Thereto the device has control means for recording the meta-data in at least one hidden location of the record carrier which hidden location is not or less likely accessible for storing data according to the predefined recording format.
Claims16
Device for recording digitally encoded real-time information, such as video, according to a predefined recording format information on a record carrier, which device comprises recording means (22) for recording marks representing the digitally encoded real-time information, and
- control means (20, 31) adapted
- for gathering meta-data comprising parameters of the digitally encoded real-time information, and
- for controlling recording the meta-data in at least one hidden location of the record carrier which hidden location is not or less likely accessible for storing data according to the predefined recording format.
Method of recording information on a record carrier, which method comprises
- recording digitally encoded real-time information, such as video, according to a predefined recording format,
- gathering meta-data which describes parameters of the digitally encoded real-time information, and
- recording the meta-data in at least one hidden location of the record carrier which hidden location is not or less likely accessible for storing data according to the predefined recording format.
Device for retrieving information from a record carrier, which device comprises reading means (30) for reading marks representing digitally encoded real-time information, such as video, according to a predefined recording format, and control means (20, 32)
- for gathering meta-data which describes parameters of the digitally encoded real-time information from at least one hidden location of the record carrier which hidden location is not or less-likely accessible for storing data according to the predefined recording format.
Record carrier comprising a track carrying marks, which marks represent
- digitally encoded real-time information, such as video, according to a predefined recording format, and
- meta-data which describes parameters of the digitally encoded real-time information,
- the meta-data being located in at least one hidden location of the record carrier which hidden location is not or less likely accessible for storing data according to the predefined recording format.
