Note StadiumVision deployments should avoid DMPDM, except to check the firmware’s “build date”
or release version number. For other tasks, please use the management dashboard software and
documentation that came with your StadiumVision purchase.
Tip A software user guide for DMPDM is available on Cisco.com. See

TVzilla
A Cisco-customized web browser is sometimes preinstalled on DMPs. We call this browser TVzilla.
Note Does your DMP model run TVzilla in this release? Some might not. See
http://cisco.com/go/dms/dmp/datasheets.
TVzilla uses code from the open source Mozilla project and supports JavaScript. TVzilla supports the
following file types.
• HTML and TXT
• GIF, JPEG, and PNG
• SWF (Shockwave Flash) — for supported versions, see your DMP datasheet at
http://cisco.com/go/dms/dmp/datasheets.
You cannot install browser plug-ins or any other software in TVzilla, whether to support additional file
t
ypes or for any other purpose. No Java Runtime Environment is installed.
Cisco Hinter
A technique called interleaved RTP makes it possible for some centrally managed DMPs to play
delay-insensitive unicast MPEG streams through RTSP connections. A streaming server can then
transmit this “hinted” video to DMPs on demand. The key advantages of interleaved RTP are that data
loss is impossible inside the hinted program stream, and yet synchronization of audio to video never
suffers, even in high-definition.
Cisco Hinter i
s software to prepare and stage MPEG files for interleaved RTP transmission through the
open source Darwin Streaming Server component on a Cisco
Digital Media Manager (DMM) appliance.
