MPEG-2 Configuration
VBrick MPEG-2 Appliance Admin Guide 25
Configuration: Encoder > Video
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.
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.

Stream Type
The user can configure the appliance to transmit an Elementary
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.
