High-Speed Encoding Addresses Trends in CE and
Automotive Markets
Home Media Servers, HDD based stereo systems,
High Speed CD rippers

• Growing variety of consumer equipment capable of
  audio storage
• Need to be able to rip music quickly without the
  complexity of a PC
• Need low-cost, consumer equipment price points

Navigation, Multimedia Systems, Virtual CD
changers and A/V Foundation Systems

• HDD in navigation systems used as audio storage
• Eliminate mechanical CD changers with NAND
• Need to playback from other than radio/CD (USB,
  SD/MMC)
• CD Ripping needs to be quick and transparent

High-Speed Encoding Market Needs

• End User Experience
• Users dont want to spend a long time ripping CDs
• System should be usable for other functions while
  ripping

• Cost-effective System
• Needs to be cost-effective versus a PC-based
  system
• Needs to hit consumer price points

• Design Flexibility
• Design final product from menu of hardware
  interface options
• Design final product from menu of software
  algorithms

• Time to market
• Growing and evolving consumer/automotive encoder
  market
• Need to get products out quickly to capitalize on
  current trends

TIs New High Speed Encoding System Solution

• Design flexibility
• Supports choice of popular encode formats
  including MP3, WMA, ATRAC3, and AAC
• Interface to CD, USB, HDD, NAND, Disk-On-Chip and
  others

• High Speed Encode solution improves end user
  experience
• Fast transfer from CD to storage with up to 20X
  ripping speeds
• Simultaneous encode and decode enables listening
  while ripping
• Consumer price points
• DSP manages all the interfaces eliminating
  microcontroller cost
• Single DSP for encode and decode reduces chip
  count
• Modular, scalable solution allows tailoring to
  meet cost target

• Time to market
• Drivers, encoders, decoders, and system software
  included as part of the solution
• High Speed Encode EVM is a full prototype system
• 3rd party Mistral helps speed design and
  customization
