EQAM’s and Bandwidth What is the relationship?

• MSO’s need more bandwidth to offer more content– Offer more HD– Offer more VOD/on-demand– Offer more high speed data (Internet Access)

• BW Reclamation and Expansion– Use SDV to reclaim BW– Digital Simulcast, DTA, and the transition to all digital– Create new BW: expand to 1 GHz plants

• When more BW is available:– What to do? Add more QAM channels– How to do it? Install more EQAM devices!



• Deliver Narrowcast Content

• GigE to QAM/RF

• Deliver digital video and audio– VOD and SDV– Broadcast Video

• Deliver high speed data– M-CMTS– DOCSIS 3.0 channel bonding

• Competition– Functionality and reliability– Density– Price/QAM

Narrowcast Bandwidth Trends

• Tuners (STB’s) per downstream service group are decreasing

• QAM channels per downstream service group are increasing

• QAM channels per EQAM RF port are increasing (density)

• $$/QAM channel is decreasing

• Capacity for simultaneous usage is increasing– Approaching Switched Unicast Model!

End Game: Switched Unicast Dedicated BW per Subscriber!

• Switched Unicast allow for 100% simultaneous usage

• Each subscriber has their own digital channel– Tuning happens in the headend

• Each subscriber is individually accessible– Accessibility of an IPTV system

• Huge opportunity for highly targeted advertising– Send relevant custom advertisements to individual subscribers



EQAM Key Features

Economics– Price/QAM

Environmental– Physical size (RU) and weight– Power draw (watts/QAM)– Operating Environment

QAM/RF Output– RF performance (DRFI)– Frequency Range – QAM density (QAM/RF port)– RF output redundancy– Output level / combining

GigE Reception– De-jitter capability (buffer size)– Support for IGMP V3– Transport Stream Redundancy

Systems and protocols– SDV standard protocols– Standardized UDP port mapping– M-CMTS

Encryption– Broadcast encryption– VOD encryption (CTE/Privacy)– DTA security

REM1000 Redundancy Switch• REM 1000 Overview

– Used to protect against APEX module failure– Eliminate need to re-wire RF if APEX module fails– Switch has 12 RF inputs and 10 RF outputs– Two APEX1000 units per each REM1000 switch– APEX optional redundancy configuration

• Each APEX can provide up to 5 RF outputs (up to 40 QAM)• One RF output is redundant

• REM1000 Requirements– Bi-directional communication with APEX units– 3 Ethernet ports (allow point to point connections, APEX to switch)– Fail in passive manor so not single point of failure
