DVS-644/SCTE18 Client Configuration Interface, top half of table
Discussion:
Various information fields must be configured to identify and correctly communicate to the DVS-
644/SCTE18 client. The most basic fields are the
Remote Host Unicast or Multicast
and
Remote Host Port.
Enter these addresses according to the specific DVS-644/SCTE-18 target server. Often this is an MPEG-2
multiplexor, such as a Stream Encryptor Modulator, serving a defined set of digital cable channels.
Multicast TTL
- This value determines the number of router hops that are allowed during multicast of the
DVS644/SCTE18 Cable Alert Message before the UDP message is blocked. Enter a sufficiently large value
(from 0..200) if you are multicasting. Multicasting requires proper configuration of a network outside the DASDEC
II.
Advanced DSG Delivery
- Defaults to Disabled. The default method for delivering the DVS644/SCTE18 Cable
Alert Message MPEG2 system table uses a standard MPEG2 Transport Stream. Check to switch to Advanced
DSG delivery. Use DSG delivery for communicating with DOCSIS Standard Gateway equipment.
If
Advanced DSG delivery
is used then the a text field option is displayed for setting the
Network MTU
(Max
transmission unit) is available. This defaults to 1500 but can be set lower if needed based on a specific network.
