Media Server Development Challenges
4
Service Provider Needs

• Deliver highest quality cross-network services
  for mobile and IP devices
• Voice/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

5
Service Provider Needs

• Video deployment demands are still relatively
  small compared to voice deployment
• Flexible channel media type assignment is
  required to reach entire audience
• Price and ROI
• Smooth and flexible migration from voice
  systems to voice and video systems
• Fast integration into current infrastructure

6
Media Server Development Challenges

• Growing number of codecs
• Interoperability signaling and media
• Quality issues due to environmental changes

Buying Boards or Chips

• Why Boards?

• Why Chips?

• 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

• 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
11
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 -gt 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

12
Why Run 3G-324M (H.223) on the DSP and Not on
the Host ?

• Minimal delay -gt higher overall quality gateways
• Same DSP runs 3G-324M, audio transcoding, video
  transcoding and sends audio/video RTP directly to
  IP network
• Scalability
• When H.223 is running on the DSP, host processor
  performance is not a limiting factor for moving
  to higher densitiesjust add more DSPs/boards.
• Lower operational expenses
• Less components in the system. No need for
• Specific DSP board/module for audio transcoding
• Specific DSP board/module for video transcoding
• Controller module/board for 3G-324M

13
Media Server Development Challenges

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

• Generic

• Generic
