PacketType Statements
The PacketType is the second-level element within the file. It is nested within the Protocol
element.
There must be at least one PacketType element within the file but there is no maximum number.
Each PacketType element describes an individual packet among the ones defined for the selected
protocol. Only those packets that are of interest need be defined: for any other packets, the
Extended DataView will simply display the message ‘No Definition Found’ together with the
packet’s Data ID.
<PacketType Attributes > … </PacketType>
Attributes:
PacketIdentifier=" string " (required)
where string specifies the Data ID that (together with any Secondary Data ID, see below)
identifies the type of ANC packet that is being described – as given in the specification for the
packet. This identifier must be unique to the packet as it is the item by which the software
identifies which XML description to use to analyse the data it contains.
e.g. PacketIdentifier="0x2E7"
PacketName=" string " (required)
where string describes the Packets decoded by this PacketType element. This name is displayed
at the start of the description of the packet.
e.g.
PacketName="HDTV audio Group 1"
DescriptionLabel=" string "
where string defines a heading to go above the data. This is particularly useful where a tabular
layout is used for the data.
e.g. DescriptionLabel=" Sample Z V U C F"
LabelOffset=" integer "
where integer specifies that the above label should be positioned one or more lines below its
default position in the Extended DataView display.
e.g.
LabelOffset="1"
Repetative=" boolean "
where boolean is set to "true" where the target packet consists of a repeated sequence of bit
fields and "false" in all other instances. Note:
You aren’t asked to specify the number of
repetitions because this can be deduced in any particular case from the length information given
in the packet header.
e.g.
Repetative="false"
SecondaryPacketIdentifier=" string "
where string specifies the Secondary Data ID (SDID) associated with a Type 2 ANC packet.
Note: This attribute is optional and may be omitted for Type 1 PacketType definitions.
e.g. SecondaryPacketIdentifier="0x260"
Example:
<PacketType PacketIdentifier="0x2E7" PacketName="HDTV audio Group 1"
Repetative="false" DescriptionLabel=" Sample Z P C U V" LabelOffset="1">
