• No shrink-wrap solution
– New Franchising Companies with ready-to-deploy systems.
• Needs a return link, usually a dial-up ISP.
– Wireless return link, GPRS/GSM
• Cost/scalability problems
– Sectorized antennas, Crown Castle UK.
• Needs to be tested/developed for ATSC.
– New ATSC proposals.
• TCP/IP issues over asymmetrical and long delay networks
– There are a number of proposals and implementations to overcome TCP/IP

Content Encoding
• Encoding
– Higher compression MPEG4
• Saves storage & transmission cost
– Near DVD quality at much lower bit rate
• 700K – 1.5M bit/sec
• CIF resolution
– Off-line or On-line encoding
• Off-line: multi-pass, VBR encoding for highest possible
visual quality
• On-line: single pass, CBR encoding for real time streaming
– ISO Standard
• Multiple suppliers
• Philips, Envivio, iVast, DiVX…etc
Hotel Video Distribution
Content Reception
• Small footprint 19’ rack
– VHF/UHF Antenna or Satellite dish
– RF signal divider
•
Optional for multiple channels
– MPEG-4 STB
– RF Modulator
•
1 modulator for 1 STB
– RF signal combiner
•
Optional for multiple channels
– Small TV for monitoring
•
• 1 TV per channel
