Packet Identifier of a MPEG2 Transport Stream Packet.

The PID is a 13-bit number that is used by the MPEG2 Multiplexer or MPEG2 Demultiplexer to identify the Elementary Stream to which this TS Packet belongs. A MPEG2 Transport Stream can thus contain up to 2^13 = 8192 multiplexed Elementary Streams.

Some PIDs are defined by the MPEG2 Standard and the DVB Standard to be used for reserved purposes:

**Reserved PIDs**
PID (hex)	Purpose
0x00	PAT - Program Association Table
0x01	CAT - Conditional Access Table
0x10	NIT - Network Information Table
0x11	SDT - Service Description Table
0x12	EIT - Event Information Table
0x13	RST - Running Status Table
0x14	TDT - Time and Date Table
