Update a DVD Server With New Files
Overview
This section describes how to update a dvd server with new files to ensure that set-
top boxes receive needed data.
To support SARA’s DVD burning capability, the dvd server places the following
To support SARA’s DVD burning capability, the dvd server places the following
files on the BFS:
•
•
dvdImage.bin, which is sent over an inband data path
•
dvdIndex.dat, which is sent over an out-of-band data path
Whenever these files are revised, the dvd server must be updated with the new files.
Otherwise, the new files will not be placed on the BFS and DHCTs will not receive
the new data. As a result, DVR-DVD set-top boxes are unable to fully support the
DVD burning feature.
Why Are These Files Needed?
As the following definitions explain, the SARA client uses the dvdImage.bin and
dvdIndex.dat files to inform subscribers that copy-protected content on the disc can
be played back by only the authorized device.

dvdImage.bin —A DVD ISO disc image
file that the SARA client writes to the
first border of a Cisco Trusted Domain
Format (TDF) disc. Because content on
the TDF disc is encrypted and can be
played back by only a specific DVR-
DVD set-top box, this image serves to
warn the subscriber that the DVD
cannot be played when it is inserted into
a commercial DVD
player or an Explorer DVR-DVD set-top box other than the one that burned the
program. The image displayed is similar to the example shown above.
Content that is tagged as “copy freely” is burned using standard DVD-Video
Content that is tagged as “copy freely” is burned using standard DVD-Video
format. These discs will not have this image because they can be played back on
any commercial DVD player as well as on other Explorer DVR-DVD set-top boxes.
Note: Cable service providers may use any DVD authoring product to customize
Note: Cable service providers may use any DVD authoring product to customize
the dvdImage.bin file that Cisco provides. When customizing the image, cable
service providers must ensure that the file size is less than 1 MB.
•
dvdIndex.dat — A text file that tells the SARA client where to look on the BFS to
find the ISO image file, which the client uses when burning TDF discs.
