FIELD APPLICATIONS 

3.  Field Applications

In this chapter we illustrate some of the common field applications for the DigiVu systems. This listing is not exhaustive and 

does not show every combination of channel or program encoding/insertion. Reference to DigiVu infers all DigiVu platforms 

unless a specific model is stated.

FYI: 

In this guide, reference to DigiVu infers DigiVu 3RU, DigiVu CD 3RU and DigiVu Mini 1RU 

unless the model is specifically stated. Reference to DVIS is synonymous with DigiVu as these 
products run on the same firmware.

3.2  Summary of Insertion Applications

3.2.1  Insertion of a Carrier Into a Blank or Empty Channel Spectrum

It is possible to insert the DigiVu QAM carrier into spectrum space left intentionally blank without the use of a channel deletion 

filter. Generally the two scenarios for insertion are in between existing adjacent system channels and at the upper edge of the 

cable system passband.

See 

“QAM Insertion Without Decoding” on page 3-3

3.2.2  Insertion of a Carrier with use of a Deletion Filter to Remove an Existing Carrier

Using the optional channel deletion filter, the target system channel may be effectively removed to make space for the inserted 

channel. In this case, adjacent system channels are minimally affected through the DigiVu “Brick Wall” channel dropping filter 

technology.

See 

“Insertion into Locally Deleted QAM” on page 3-4

3.2.3  Digital Program Insertion into an Existing QAM with Existing Programs

This application is intended for ‘in the clear’ or encrypted QAM channels that have programming that is able to be sacrificed 

or for QAM channels that are designed for this program insertion feature. Encrypted programs will be replaced with an ‘in the 

clear’ program.

See 

“Insertion into Under-utilized QAM (Add/Drop)” on page 3-4

3.2.4  IP Video Content Insertion

This application uses the DigiVu encoding capability with IP output to locally insert programming into an IPTV property or 

remote hub for distribution or Headend encoding application.

See 

“IP Video Content Insertion” on page 3-5

3.2.5  Video Back Haul Schemes

These  applications  uses  the  DigiVu  encoding  capability  with  IP  output,  QAM  output  to  haul  a  special  remote  origination 

program to a hub for distribution.
