B2C2 Broadcast Software
• B2CAS– IP Multicast CAS system
• B2MON– Monitor Over Network, Multicast based network
control and monitor.
• B2CAST– IP Multicast data distribution with error correction.
Used for remote software upgrades, etc.
• B2Capture and B2Analyzer– Capture live streams, store and analyze streams.
Corporate Software
• What is it?– IP Data, Unicast or Multicast– IP data that isn’t related to the Video/Audio program.– Other data related or not related to the Video/Audio program.

• 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

• The next best thing since color TV
• Consumers want the movies when & how they want
• Content Providers & Service Providers know VOD may the “Killer App”
• But it has not been possible for mass consumers
Video On Demand
VODServer
Unicast ApproachNot for Broadcasters
• Not scalable• Only possible for small scale services• i.e., Hotel VOD
Video On Demand
VODServer
DSL/Cable Modem UnicastNot for Broadcasters
• Not scalable• Backbone congestion & expensive• Server congestion
Video On Demand
VODServer
DSL/Cable Modem with Edge ServerNot for Broadcasters
• Reduced backbone traffic• Edge Server still congested• Expensive – no economy of scale

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

Media Distribution - Business
• Distance Training/Learning– New networks being developed.
– Content delivery directly to the desktop.
• Digital Billboard– Outdoors
– In-store advertising/Promotion• Plasma displays replacing posters, other advertising.
• Updates, changes and new content broadcasted.
• Most content video encoded in MPEG4, Flash.
Conclusions
• Consumers– New devices will enable services that haven’t been possible or imagined.– New services just starting– Content protection will be a key– Main contents will be Games, Music, Films, etc.– New standards, video encoders improving quality/compression
• DASE/MHP• ITU-T H.264
• Business– Cost saving opportunities with new services.– Leverage existing infrastructure.– Main content will use MPEG4/H.264, Flash, etc.– Enhanced presence for telecommuters.
