| Name | Numberof bits | 32-bit BE mask | Description |
|---|---|---|---|

| Sync byte | 8 | 0xff000000 |
Bit pattern of 0x47 (ASCII char ‘G’) |
| Transport Error Indicator (TEI) | 1 | 0x800000 |
Set when a demodulator can’t correct errors from FEC data; indicating the packet is corrupt. |
| Payload Unit Start Indicator | 1 | 0x400000 |
Set when a PES, PSI, or DVB-MIP packet begins immediately following the header. |
| Transport Priority | 1 | 0x200000 |
Set when the current packet has a higher priority than other packets with the same PID. |
| PID | 13 | 0x1fff00 |
Packet Identifier, describing the payload data. |
| Scrambling control | 2 | 0xc0 |
’00’ = Not scrambled.For DVB-CSA only:’01’ (0x40) = Reserved for future use’10’ (0x80) = Scrambled with even key’11’ (0xC0) = Scrambled with odd key |
