IP Overhead

The IP overhead calculation when mapping MPEG-2 TS packets into IP frames is
shown in

Table F.1

Table F.1 IP Overhead

Overhead

factor

Comments

MPEG-2 TS

1.0

UDP 1324/1316

1.006

(UDP header=8 bytes)

1344/1324 = 1.015

(IP header=20 bytes)

Ethernet

1358/1344

1.010

(Eth header=14 bytes)

Total overhead factor becomes: 1.006 x 1.015 x 1.010 = 1.031 or 3.1% overhead.

Note:

The number of MPEG-2 TS packets one can map down into each UDP
frame is variable (between 1 and 7). Usually 7 is used for minimum
overhead. This is also used in the above calculation.
