MRFP Development Challenges

IMS Service Provider Needs
Deliver highest quality media processing to support mobile and IP services
Audio/video mail
Video portal
Video conferencing
Multimedia servers
Recording servers
Support multiple formats for multiple devices
Combine traditional TDM-based applications with next-generation IP Audio/Video services
Simple migration path for supporting future formats

IMS Service Provider Needs
A single solution for all media types
Flexible channel media type assignment is required to reach entire audience
Price and ROI
Smooth and flexible migration from ‘audio’ systems to ‘audio and video’ systems
Fast integration into current infrastructure

Growing number of codecs
Interoperability
Each media type has its own interoperability issues
New media formats are introduced – i.e., iLBC, H.264, WMA9, WMV9
Quality issues due to environmental changes
DSP code optimization
Application type optimization
System bottlenecks
New hardware standards

Buying Boards or Chips
Why Boards?
Pre-requisite:
Standard form factor or
Standard mezzanine-card connector
Lowest risk
Lowest initial investment
Cheapest solution in the long run
Negotiation
Change vendor
Easiest migration path to next generation DSPs
Why Chips?
Proprietary form factor
Single-DSP solutions
Very high volumes (10K+)
Prediction: By 2008 all new Tier-I infrastructure solutions will be based on standard boards and modules that are made by third parties.

New Hardware Standards Well defined control mechanism in spec No defined control mechanism Up to 30 Watt Up to 15 Watt Hot swap Non hot swap Rapid I/O TDM GB Ethernet MII PCI Express PCI AMC PTMC Megs of traffic 10s of Megs in back plane Gigs of traffic 10 Gig per AMC in back plane Not Ready for next generation DSPs Ready for more powerful DSPs

Why Put Audio & Video on the Same Chip/Module?
Easy migration path from 0% video / 100% audio to 100% video / 0% audio and anything in-between
Minimal system delay -> higher overall quality
No need to separate audio from video and send each to a separate chip/module
Easier to establish lip-sync between audio and video when packets are lost or delayed
Lower operational expenses
Only need to support one chip/board
Lower integration efforts
Single API for audio and video
No need for an aggregation device to combine/split audio and video

A typical MRFP is composed of four components:
Media processing DSP code
Host-based state machines and APIs
Hardware platform
MRFP application
