Presented by Sachin Rehan

DVIS Product Overview

• The DVIS line of products are network-edge local content insertion devices for digital video networks

DVIS

DVISn

DVISm

Any application requiring locally generated baseband analog

content to be delivered within a property provisioned with digital

only TVs, STBs or DTAs or where analog spectrum is not available

• Security or surveillance camera feeds (MDU’s, retirement

homes, etc.)

• Text/character generator or local information channel (hotels,

conference centers, gated communities, etc.)

• ‘Custom’ insertion of encrypted digital channels to a

commercial property lineup (I.e. insertion of specialty channels

to a hotel lineup)

• Distribution of ‘in-house’ or private channels throughout a

property (I.e. sports stadiums, network studios)

DVIS Applications

‘Old’ way – Analog System

‘New’ way – Digital System

• QAM modulated carrier on each EIA frequency

• Multiple programs per QAM carrier

• Virtual channel map instructs STB which frequency to

tune to and which MPEG program from multiplex to select for display

ATX Digital Video Insertion Products

• The “DVIS” product line was developed to facilitate

any of these applications

• Over 2000 “DVIS” units have shipped to date

• The DVIS consists of three MDU Hardened

products:

• DVIS, DVISm and DVISn

DVIS

DVISn

DVISm

•Modem Pocket


DVISm

•MDU hardened, wall mounted enclosure with front access to all plug-ins and connections

•Integrated TS Multiplexer,

QAM modulator & RF upconverter

•Scalable thru plug-in application cards:

•Single/Dual encoders,

•QAM demodulator

•10/100/1000 Copper/SFP output


DVISm•QAM output: 1-10ch

•QAM output Add Drop: 1-4 Ch

•IP:10/100/1000 /QAM output: 1-4Ch

•Integrated RF Management and RF Filter eliminates the

requirement for external equipment



DVISn•Small form factor, MDU hardened, wall or table mounted mounted enclosure

•Integrated TS Multiplexer, QAM modulator & RF upconverter

•Cost effective solution with QAM or GigE output only (Add/Drop function not supported)

•QAM output: 1 or 2ch

•GigE output: 1 or 2ch

•QAM/Add Drop currently not supported but could be developed



Form Factor

• MDU hardened wall mount solution – no need to install a wall

rack

• All connections & interfaces located on front panel and are

concealed behind a lockable door

DVIS Advantages

• Rack mount ‘ears’

available for rack mount

applications

Integrated RF management

• All RF connections, directional couplers

and leads are built-in for ‘add/drop’ type

application

• No need for external RF splitting or

combining with additional DCs, external

filters, jumpers, etc.

• SIGNIFICANTLY SIMPLIFIES AND

REDUCES TOTAL INSTALL TIME AND

COST

• Input and output test points for

installation and troubleshooting without

disruption of RF signal

DVIS Advantages

Scalability & Modularity

• PCI based expansion cards allow for easy field upgrade up to

4 (DVISm) or 8-10 (DVIS) channels plus demod functionality

DVIS Advantages

• Hot-swappable cards to

eliminate any service

interruption

• Removable fans, power

supply, filter, encoder

and demod cards for

easy field upgrade,

maintenance or

replacement

Filter Expertise

• ATX has been manufacturing and selling filters to the cable

industry (previously as PCI filters) for over 10 years

− Invested significant R&D effort to optimize filter tuning for DTA environment

− Current best performing filter on market (competitive filter performance is questionable at high freqs)

• One Stop Shop

− Can order DVISm with encoder card(s), demodulator card and

deletion filter with 1 part number

− No need to deal with multiple vendors for support on various

components of insertion solution
