Chapter1 Product Overview
New Features in IP/TV Version 3.5
Support for Different Viewers
IP/TV Server Version 3.5 and IP/TV Content Manager Version 3.5 support both
the QuickTime Player and IP/TV Viewer. Users can use either IP/TV Viewer or
the QuickTime plug-in to watch a program. Only the QuickTime plug-in—and not
the QuickTime standalone client—is supported by this feature.
Web-Based Question Manager
IP/TV Version 3.5 introduces a web-based Question Manager. This feature allows
users to access Question Manager from IP/TV browser plug-in as well as from the
QuickTime plug-in window. The Click Here to Ask a Question to the Speaker
link in the browser window takes you to the web-based Question Manager. The
questions entered in the Question Manager window are then sent to the
QuestionManager daemon on IP/TV Content Manager. For more information on
the web-based Question Manager, see the “Using Question Manager” section on
page 4-32.
MPEG-4 Codec for SlideCast
In order to improve the clarity of slides in the SlideCast feature, IP/TV
Version3.5 uses MPEG-4 Simple Profile encoding. Previous versions of IP/TV
used H.261 encoding for SlideCast. MPEG-4 supports higher resolutions and
better compression than H.261 and ensures quality SlideCast presentations.
Improved Streaming
IP/TV Version 3.5 supports four to eight MPEG streams per server on the new
IP/TV Server hardware: the Cisco IP/TV 3426 and IP/TV 3427 Broadcast Servers.
Table 1 -1 describes the new hardware platforms and the number of
streams supported.
