Analog to Digital Transition(2008-2010)
• Forced Thinking - What are our needs?– Upgrade Head-ends
(signal processors/modulators)– Replace Old CRTs to LCD TVs (ATSC/NTSC/QAM)
– Digital (HD) Signage replace SD System?• Costs – Ethernet system vs Existing RF network
– $600-1200 drop for Cat 5 (14 locations)– Add Media Player per TV
Digital Signage Needs
• What should it do…– Need for separate content in different locations– Want ability to easily change from digital signage
(multiple channels) to TV channels– Adjust volume/mute– Need Control of TVs– Do all of this with CM system
Cable-Modem System• B/T Cable Modem Termination System– Uses existing RF network (DOCSIS)– Interfaces with IT network– Static IP & MAC Address Filter
• At TV – Splitter (TV Ant & CM)– Cable-modem– Serial Server (RS-232 Control)
Ethernet
