packet identifier (MPEG) (PID)

  1. In DigitalVideo Broadcast( DVB), the Packet Identifier (PID) is used for error protection. It is a unique integer value that accompanies the Packetized Elementary Stream( ES) within a single or multiple program streams. Each individual stream is identified with Packet IDs. Arbitrary digits are assigned to the PIDs, but they remain the same for the same media content - audio, video, ancillary data - across the entire program stream. The packet identifier enables the receiver to filter out and process the corresponding data packets.
  2. Packet identifiers (PID) are also used in the USB protocol, where all transaction types start with an 8-bit PID field.
