iTV (DASE) vs. Internet

• TV is relax media but PC is intensive media
• Internet always online, TV is broadcast defined
• Internet (PC) Application runs on more powerful
  H/W then DTV
• DASE 1 page browser, Internet scrollable.

Whats possible with DASE

• Program dependent data service
• Contents and applications selected to maximize
  relevancy and compelling complement to A/V
  content
• Example Music, Drama

Consideration of Set-Top-Box

• Environment Limitations
• CPU power 200MIPS Pentium, 100Mhz Memory
• Middleware optimization
• Font - unpredictable layout concerns
• Metrics
• Screen resolution (DPI) 72DPI 11 Pixel/pt,
  optimized resolution
• Outline font
• Content Size
