When Chu not be with the Multicast MAC Address of identification code, the fixed receiving end 2 in all information of current UHF band reception, no longer into
The switching of line frequency section.
The building of multicast address is also associated with Encryption mode (encryption mode), according to encryption mode, determines multicast
First numerical value of the 5th byte of MAC Address is also ready for the calculating of next data packet length.Such as:
When encryption mode is Open, 01-00-5e-25-C0-01；
When encryption mode is WEP, 01-00-5e-25-D0-01；

MAC Header, FCS, IP Header, UDP Header length are fixed, such as: MAC Header=24, FCS=
4, IP Header=20, UDP Header=8；(remarks: MAC Header:MAC head；FCS；Frame Check Sequence；IP
Header:IP head；UDP Header: User Datagram Protocol head).
The length of MAC Extra Length with cipher mode and QOS, HT whether unlatching changes,
Therefore, UDP Data=Total Length+C, C are customized constant.
Constant C is once define, then data packet length and actual content mapping are as follows:
Send 1<--- -->UDP data length=1+1
Send 2<--- -->UDP data length=2+1
......
