	MPEG-2 Configuration
Audio PID	MPEG-2 transmits its data in packets of 188 bytes each. At the start
	of each packet is a packet identifier (or PID) that identifies the data
	stream associated with that packet. It is possible that a non-VBrick
	decoder may only accept audio streams with a certain PID setting. If
	so, then this feature allows compatibility with these decoders.
Video PID	MPEG-2 transmits its data in packets of 188 bytes each. At the start
	of each packet is a packet identifier (or PID) that identifies the data
	stream associated with that packet. It is possible that a non-VBrick
	decoder may only accept video streams with a certain PID setting. If
	so, then this feature allows compatibility with these decoders.
PCR PID	MPEG-2 transmits its data in packets of 188 bytes each. At the start
	of each packet is a packet identifier (or PID) that identifies the data
	stream associated with that packet. It is possible that a non-VBrick
	decoder may only accept PCR (Program Clock Reference) streams
	with a certain PID setting. If so, then this feature allows compatibility
	with these decoders. Note that certain decoders may require the PCRs
	to be embedded in the video stream. If so, these decoders are not
	compatible with the VBrick encoder.
Destination 2	The user can configure the appliance to transmit an Elementary
Stream Type	stream as a secondary stream. A video ES, or video elementary
	stream, consists of all the video data for a sequence, including the
	sequence header and all the subparts of a sequence. A Transport
	stream contains both video and audio.

These parameters are used to configure the Encoder video settings. The encoder video and audio configurations change if the appliance has an SDI, Serial Digital Interface. Please refer to SDI Configuration on page 57 for more information.
