Live-Video and ACNS: Different documentation?

Answered Question
Sep 30th, 2009

I had found two statements regarding live- video and ETV:

First in

http://www.cisco.com/en/US/partner/prod/collateral/video/ps9339/ps7063/data_sheet_c78-504500.html

"... Cisco ACNS provides both live unicast and multicast streaming services and on-demand access in which digital media files are cached locally for retrieval and viewed over the WAN at LAN speeds (Figure 3)."

And the second statement in

"Cisco Digital Media System 5.1 Design

Guide for Enterprise Medianet":

"... For Digital Signage and Enterprise TV live content, multicast is required as the transport. Cisco ACNS

does not support unicast to multicast conversion for the delivery method used by Digital Signage and

Enterprise TV. For this reason, Cisco ACNS does not provide any benefit for live content...."

Is there an difference or is this an failure?

I have this problem too.

We use ACNS to deliver both unicast and multicast for Desktop Video. We are not using Digital Signage yet, but I think the 2nd statement must only apply to Digital Signage. Yes, there is different documentation for DMS and ACNS, and they are almost totally exclusive of each other.

I think the first statement should read:"ACNS does support unicast and multicast splitting for live broadcasts TO THE DESKTOP and with Windows Media streaming"

The second statements hints to HighDefinition streaming which is mostly compressed with H.264 MPEG4, and i don't think ACNS is able to split this (or convert unicast -> multicast)
