Jelaskan Unsur penting transport stream dari Transport stream dalam bahasa sunda

A packet is the basic unit of data in a transport stréam.  It consists of a sync byte, whose value is 0x47, followed by three one-bit flags and a 13-bit PID.  This is followed by a 4-bit continuity counter. Additional optional transport fields, as signaled in the optional adaptation field, may follow. The rest of the packet consists of payload. Packets are 188 bytes in length

, but the communication medium may add some error correction bytes to the packet.  DVb-ASI uses 204 bytes and ATSC 208 bytes as transport stréam packet. (DVB t=8 and ATSC t=10 i.e. extra bytes = 2*t). ATSC transmission adds 20 bytes of Reed-Solomon forward error correction to créate a packet that is 208 bytes long .  The 188-byte packet size was originally chosen for compatibility with ATM systems    .
