VBrick Systems VB5000, VB6000, VB4000 manual Configuration Decoder Video

Configuration: Decoder

Configuration: Decoder > Video

The VBrick decoder is used to uncompress MPEG streams and display them on a TV or monitor.

Decoder Video	The format can be configured to be NTSC (30fps), PAL (25fps) or
Format	PAL-M (30fps). PAL-M is a video format standard used in Brazil. The
	main difference between PAL and PAL M is a lower resolution (525
	lines instead of 625) and a higher frame count (30 frames per second
	at 60Hz versus 25 frames per second at 50Hz). Note: Changing and
	applying this parameter will cause the VBrick to reset.
Logo Display	Lets you display the VBrick logo on the decoder output (monitor).
	VBrick provides a Logo Customization Utility (available on the
	website) if you want to create an individualized logo.
No Data Mode	This allows setting the screen for a decoder with no video input to
	having either the last screen appear either frozen or blank.
Closed Caption	This setting enables or disables closed captioning. Closed Captioning
	does not operate when the Picture in Picture feature is selected. It is
	necessary to disable PIP. In SIF mode only CC1 and CC2 are valid.
	CC3 and CC4 fields are not supported.
PID	MPEG-2 transmits its data in packets of 188 bytes each. At the start
	of each packet is a packet package identifier (or PID) that identifies
	the data stream associated with that packet. Because the MPEG-2 data
	stream might contain multiple video programs, the decoder has to
	choose a particular video channel to play. The PID selection provides
	that feature. If the user selects the automatic option, the first video
	PID identified will be used to select the video channel.
