Note

From Multicam 9, the VarID has been introduced to allow a redundant

architecture where the VarID can be identical on two different servers. All

servers can stay on the same SDTI network. Consequently, this does not

require a full replication of the XNet network. With the Um ID, the full

replication was necessary as this clip ID has to be unique on the XNet

network.

4.2.2 CLIP IDENTIFIERS USED BY THE PROTOCOLS

VDCP Protocol

The VDCP can use two identifier types, the ‘fixed 8-byte length’ identifier and the

‘variable length’ identifier. The XT[2] server imposes the maximum length for the

variable ID, i.e. 32 characters in this instance. The VDCP protocol will use

completely different commands depending on the ID that will be used. The VDCP

protocol provides only this variable ID management.

The uniqueness and visibility functions are provided by the XT[2] servers to allow

the network architecture and redundancy management.

The protocol configuration for the ID management is performed via two interfaces:

• Multicam Application

In the ‘RS422 Protocols’ Section, on page 1 of the Setup menu (SHIFT-F2), the

ID type field allows the users to select the ID type to be used for all relevant

protocols, i.e. Xten DD35, Odetics and VDCP. The other protocols (Sony BVW,

AVSP et IPDP) do not manage the ID type, except for OSD display.

• VARID.ini File

The configuration of the VarID settings is performed via the VARID.ini file. The

content of this file is displayed in page 5 of the Setup menu. For more

information, refer to Section 1.3.5 ‘Dolby Audio Management’, on page 15.

pending on how the VDCP protocol will be used, various configurations

detailed in the table below can be performed in the Setup menu and the

VARID.ini file. When the parameter is not specified in the table (“-“ symbol), its

value does not influence the configuration.
