4.2 CLIP IDENTIFIER MANAGEMENT WITH
PROTOCOLS
4.2.1 POSSIBLE CLIP IDENTIFIERS
LSM ID
The clips are identified with three different fields. The protocols can access the
clips via one of these fields:
LSM ID
The LSM ID is a clip identifier based on the XT[2] server structure.
The LSM ID is made up of 3 digits and 1 letter, for example 112B, where the digits
and letter represent the following elements in the server structure:
The digits after the LMS ID correspond to the Net Number of the server on which
the clip is stored, i.e. the XT[2] server ID on the XNet network. They are not part
of the LSM ID.
UmID
The UmID is an 8-bytes ID with fixed length. It is used for the unique clip
identification on the SDTI network.
By default, all the protocols access and identify the clips via the UmID.
VarID
The VarID is a 32-bytes ID with variable length and format.
It can only be used in the VDCP protocol. When this protocol uses the VarID, the
following VarID parameters need to be set up:
• Length (8 bytes, 32 bytes)
• Format (ASCII, binary)
• Uniqueness level (local = server level, global = network level)
• Protocol visibility (list of Net Numbers of the servers)
For more information on the parameters, refer to the ‘RS422 Protocol Settings’
page in the VGA Setup screen. This page is described in the XT Software
