VBrick Systems VB5000, VB6000, VB4000 manual Configuration Encoder Transport

Configuration: Encoder

Configuration: Encoder > Transport

Transport Rate	This option allows selection of the actual transport rate for the
	MPEG-2 transport stream transmitted from this encoder. If Auto is
	selected, the VBrick will choose an appropriate conservative transport
	rate, which will allow any video interval to be clearly transmitted. If
	you enter a rate that is less than the combined video, audio and over-head an
	error message will be displayed indicating that the rate selected is too low.
Actual Transport	This read-only parameter provides the actual transport stream rate. It
Rate	is of particular interest when the automatic option is selected above.
	Even if a transport rate is explicitly selected, the actual transport rate
	will differ from the selected rate since only certain rates are
	supported.
Transport Content	If the model number ends in -xxx1/-xxx2, the user can choose the
	transport content to be Video + Audio, Video only or Audio only. If
	the model number ends in -xxx0, the option is not displayed and
	video and audio always comprises the transport content.
Delay Mode	If the model number ends in -xxx1/-xxx2, the delay mode can be set
	to Low, Medium or High Delay. If the model number ends in –xxx0,
	the delay mode can be set to Low or High Delay. In low and medium
	delay modes, the Reference Distance is forced to 1 (no B frames).
	Low delay reduces latency but may also reduce video stability,
	depending on video content. If minimum latency is not an issue in the
	application, high delay will maximize video stability. Default Delay
	Mode is set to High Delay.
