MPEG-2 Configuration

Destination • Remote COM1 using Slot1 Video Endpoint. This means that all
serial data originating at the COM1 port being configured is sent
to the COM1 port of the VBrick identified as the Slot1 video
source (if Slot1 is a decoder) or to the Slot1 video destination
VBrick (if Slot1 is an encoder).
• Remote COM2 using Slot1 Video Endpoint. Slot1 Destination 1
only. Same as above except Initiator destination is COM2.
• Dedicated. When Passthrough State is set as Initiator and the
Destination is Dedicated, the VBrick appliance (whose serial port
is the destination of this COM port) can be configured and
identified using either an IP address or a host name.
• Slot1 MetaData. If Meta Data is enabled on the Encoder > Video
page, the appliance captures incoming data from the serial port and
inserts it into the stream as metadata. In a typical application, a
GPS receiver connected to a VBrick can insert ASCII strings
representing map coordinates into a stream. This information is
saved and sent as metadata with the video. This feature is disabled
when the appliance is in Edit mode.
The data is inserted when it reaches the maximum number of
characters (58 for MPEG-2) or when the Idle Timeout (see below)
between characters is reached. This feature works for all
passthrough port baud rates but can only accept continuous serial
data at rates up to 9600 baud; at higher rates there must be some
idle time between metadata strings.
• Slot2 MetaData. Same as above except the serial port data is
inserted as metadata in the video stream from the Slot2 encoder.
