The DBI memory enables the host to perform the defect management operation at a later time. Thus, no influence appears during the real time recording.
Software Defect Management
The DRT-DM is expected to be implemented into up-coming software applications (Ahead, Sonic, Pinnacle, Roxio, ArcSoft etc). The drive reports the location of any defective blocks. UDF File Driver performs the operation to ?spare the defective block?. The device driver (EDR) transports the necessary information between them.
The DRT-DM commands for implementation can be found in the "Mt Fuji Commands for Multimedia Devices SFF8090i Version 5, Revision 1.49".
The interesting thing about DRT-DM is that it can be used in "Real-Time" video streaming operations. Since the defected areas have been spotted beforehand, no loss of speed is expected when rewriting on DVD-RW media. Which is especially suited for ?seamless video recording?.
Pioneer's DRT-DM could be compared to Mt Rainier defect management in the following ways:
DRT-DM (Software Defect Management) Mt. Rainier ( Hardware Defect Management)
DVD Forum Standard for DVD-RW media
+RW Alliance Unique Local Standard for +RW media
Defect Management is controlled by the software. The Host PC can adopt flexibility accordingly to the defect level.
Defect Management by the Control Driver on the Hardware.
DRT-DM is not only for Data Recording but also a target for real-time Video Recording which Includes the DVD-Video Recording Format.
Mt.Rainier is only for Data Recording. No compatibility is expected for Video Recording.
DRT-DM adopts UDF2.0 File System. Host PC registers the address of the defective blocks in the UDF file table which enables any drives & players to read the disc / contents
The information of defective blocks are registered on the special reserve area which hinders general compatibility with drives & players to read.
DRT-DM uses UDF2.0 platform, most DVD-ROM Drives can read without any drivers installed.
DVD-ROM Drives are required to install the Address Conversion Driver to read.
