Use the Statistics tab to monitor the reception
of individual data streams. Each stream is identified as unicast
(UC), broadcast (BC), or multicast (MC), and all active PIDs are listed.

Data Streams
To receive data from an Internet/data channel,
the tuner tunes to specific streams of packeted digital information. Each stream
is identified by a code called a Program ID, or PID. The digital
receiver uses PIDs and MAC Addresses to filter the streams. There are three
types of Internet Protocol packet streams received by the digital receiver card:
- A broadcast stream is a transmission
made widely available to the general public. When a conventional radio station
broadcasts a signal, the signal blankets every antenna in the area of the
radio station; the transmission does not take a specific addressed path.
- A multicast stream is a single transmission
sent to a set of multiple users. The multicast sent from the Internet to a
network travels most of the distance as a single stream. At the last instant
the stream splits to reach multiple users.
- A unicast stream is a transmission sent
to an individual user. A media access control address (MAC address)
is a numerical code used to address the information.
