Business Applications
Those businesses that have already embraced DVD for the distribution of training
vids, understand that more space is often needed to deploy all of the material.
Just like with the example provided for consumer applications, higher bit rate
encoding of the video translates into better quality training video for the
viewer. Some of the world’s best companies, from major automobile manufacturers,
fast food restaurant chains, and others, depend on DVD for their training video
needs for one simple reason – it works.
Independent filmmakers and studios alike will appreciate
the ability to author a dual layer DVD video disc and
try it out without resorting to expensive and time
consuming replication. This group of users can now
fine tune their works on cost effective dual layer
DVD recordable discs before creating the master for
replication.
Certainly business users will appreciate the increased storage capacity of
a dual layer DVD recordable disc when distributing a large amount of data on
a single disc is needed, and even for desktop system backup and single server
backup with time and cost savings over traditional tape technologies. IT managers
can even create their system “images” for configuring client PCs
on a single disc for rapid deployment of new computers on corporate networks.
Dual Layer Implications For DVD Recording Software
Because double layer recordable discs are basically
one contiguous stream of block addresses, it’s
not very difficult for software makers to make their
disc mastering software compatible with dual layer
drives and media, as least where recording data is
concerned.
DVD Video authoring software has to manage the “break
point” of where the video will be split between
layers. This “layer jump” is typically
not visible when you watch a DVD movie even though
there is a very brief interruption to allow the player
to focus on the second layer. Managing this break point
is difficult, but straightforward once all of the video
for a project has been imported into the authoring
application where it is separated and allocated for
a video DVD.*****
