When all settings have been completed, click Submit to activate the changes. If the settings are not activated and you

close the screen, any new settings will not be applied and will be lost.

If all RF parameters are correct and the A/V ports are set up correctly, submission should enable the DVISn QAM modulator

and your new QAM channel should be available at the RF output port.

RF Output Connections

The output power level at RF OUT is set between 45 and 58 dBmV in the DVISn Settings screen.

3.4

Legacy Set-Top Box Settings

For systems using older set-top boxes such as DCT2000 and older Motorola STBs based on Cisco

Lock to V-sync and QBA Enable are selected on the DVISn Settings screen (a check mark appears in the box).

Allows modification of the video signal to increase or decrease saturation. There are

128 levels available (0-127).

A codec (compressor-decompressor) converts an audio signal to a specific file format

or streaming audio format that reduces the required storage space or bandwidth.

MPEG-1 supports stereo (two channel) signals while the AC-3 codec (licensed by

Dolby Laboratories) supports 5.1 surround sound.

Sampling rate at which an audio signal is encoded. The higher the bit rate, the better

the sound quality Audio rate options are 192, 256 and 384 kbps.

A unique number assigned to each program (1-65535).

The video PID (Packet Identifier) is a hexadecimal 13 bit number from 21 to 8190

that uniquely identifies a video transport stream in an MPTS (multi-program transport

stream) so that it can be filtered and routed appropriately.

The audio PID (Packet Identifier) is a hexadecimal 13 bit number from 21 to 8190 that

uniquely identifies an audio transport stream in an MPTS (multi-program transport

stream) so that it can be filtered and routed appropriately.

The PCR (Program Clock Reference) PID (Packet Identifier) is a hexadecimal 13 bit

number from 21 to 8190 that uniquely identifies the time base for synchronization of

individual frames or fields of the video stream and their associated audio.

The PMT (Program Map Table) PID (Packet Identifier) is a hexadecimal 13 bit number

that uniquely identifies a PMT in an MPTS (multi-program transport stream). The

PMT contains a data structure specifying which PIDs carry the video, audio and data

stream that collectively constitute the broadcast program.

Selects whether locking to vertical sync is enabled. This function is required when

DVISn signals are sent to some legacy STBs.

An IP (Internet Protocol) address is a numerical identification and logical address

assigned to devices participating in a computer network utilizing the Internet Protocol

for communication between nodes. When a computer is configured with a Static IP

address it always uses the same IP address. When a computer is configured with

Dynamic IP addressing it automatically procures an IP address when required.

A subnet mask allows the flow of network traffic between hosts to be segregated

based on a network configuration, improving network security and performance.

The node on the computer network chosen when an IP address does not belong to

any other entities in the Routing Table. Usually the node connecting internal networks

to the Internet and associated with a router and a switch.

DNS (Domain Name System) servers translate human-readable domain names into

machine-readable IP addresses and the reverse.

DHCP (Dynamic Host Configuration Protocol) automates network-parameter

assignment to network devices from one or more DHCP servers, making it easy to

add new machines to a network.
