MPEG-4 AAC-LC
IP/TV Version 3.5 supports MPEG-4 AAC-LC, which makes it compatible with
ISMA standards. MPEG-4 AAC-LC support enables IP/TV to archive and stream
high-quality audio content over low-bandwidth Internet links.
IP/TV Version 3.5 supports AAC in the following areas:
• Scheduled rebroadcast of AAC-based MP4 files
• Video-on-demand streaming of AAC-based MP4 files
• Playback of IP/TV AAC streams on Apple QuickTime 6 Player
• Playback of IP/TV AAC streams on IP/TV Viewer Version 3.5
QuickTime Plug-In Support for the Web-Based Program Guide
IP/TV Version 3.5 supports the Apple QuickTime 6.0 software as a client
application. When the web-based program guide is used to view a program, this
feature automatically launches the QuickTime plug-in if the IP/TV plug-in is not
installed. However, this feature does not work when the program’s Enforce IP/TV
Viewer option is checked.
QuickTime supports ISMA MPEG-4, MPEG-2, and SlideCast with live video and
basic audio and video streaming from the IP/TV Server to the QuickTime 6.0
client. For more information on the QuickTime plug-in, see the “Using
QuickTime as a Plug-In” section on page 6-5.
Note To view an MPEG-2 stream on QuickTime, you need a decoder from Apple
installed on your device.
