Abstract: A conversion apparatus and method is disclosed by which a file including data multiplexed therein can be edited or handled readily while maintaining the compatibility. A standard/independent conversion section converts a file of a standard AV multiplex format wherein video data and audio data are placed in a multiplexed state in a body into a file of an AV independent format wherein video data or audio data are placed collectively in a body. Meanwhile, an independent/standard conversion section converts a file of the AV independent formation into a file of the standard AV multiplex format.

Abstract: In a recording control apparatus and method, in recording areas on an optical disk, consecutive empty areas for an ALLOCATION_UNIT are reserved as reserved areas. Multiplexed data in units of packets which can be recorded in the reserved areas is recorded in the reserved areas. A remaining part of the reserved areas in which the multiplexed data in units of packets is not recorded is freed as empty areas. Subsequently, multiplexed data is similarly recorded.

If the AV data recorded on the optical disc cannot be reproduced in a real-time manner, a compile simulation unit and a compile execution unit respectively select extents from the AV data recorded on the optical disc and relocate the extents to a relocation area.

Abstract: An information processing apparatus includes a file-time-code (FTC) sort unit and a logical block number (LBN) scheduling unit. The FTC unit sorts data items recorded on an optical disk based on the playback times of the pieces of data. The LBN scheduling unit sorts the data items recorded by the FTC sort unit based on the recording positions of the data items on the optical disk. The LBN scheduling unit also uses the sorting result as the result of scheduling the order of reading the data items from the optical disk.

Abstract: A minimum buffer data amount and a minimum reproduction delay time are found from a line approximation graphic form approximating a media read line and used as a basis for determining whether or not data can be reproduced in a real-time manner from a recording medium at a requested reproduction rate. The media read line is a line expressing the change in cumulative amount of data read out from the recording medium. The minimum buffer data amount is the minimum of the amount of data stored in a buffer as data required in reproduction of the data in a real-time manner at the requested reproduction rate. The minimum reproduction delay time is the minimum of a reproduction delay time from the start of an operation to read out the data from the recording medium to the start of an operation to reproduce the data.

Abstract: The rewriting counts in respective areas of a rewritable medium are uniformized. If empty areas are present on the rewritable medium rearward of a recording start position in terms of addresses, then data is recorded in those empty areas. When no empty areas become available rearward of the recording start position, data is then recorded in empty areas forward of the recording start position. The numbers of times that data is recorded in recording areas of the recording medium are thus averaged.
