Value Propositions

SurfUP for Transcoding: Value Proposition (1)

Voice, Video and fax/modem processing on the same DSP:

Supports a flexible usage model

Always balance between voice and video processing

One integration for support of all media types

Eliminates voice/video synchronization issues

Other solutions separate Voice & Video processing (different DSPs/host) causing system to be unbalanced.

Direct DSP  network interface for lowest possible delay

DSPs connected to Ethernet eliminate the need for an aggregation unit that causes excessive delay

Solutions with DSPs that do not have direct IP network interface suffer from unnecessary delay and bottlenecks.

Open Platform

Vendors are able to add SW modules to the DSP code, in order to create a competitive advantage, without the need to recompile the DSP or host interface code

Integration of new Voice and Video standards takes no more than a few days

Closed system solutions don’t allow vendors to add value to the media processing sub-system. External memory is a must for providing an open platform.
