Hi,
 
According to H.222.0 when a Discontinuity in Continuity Counter Occurs in a
Elementary Stream Data TS Packet then payload of same packet begins with an
Access Unit Start.
 
I just could not understand what does the Broadcaster tries to signal by
setting
this Flag?How is it a Discontinuity and should the Demuxer reject this
packet
or accept it.
 
 
Consider this:
 
CASE 1
 
1)<ES_PID_Packet><AU End>
2)<Next_ES PID_Packet><DI = 1><New AU Start>
 
OR
 
CASE 2
 
1)<ES_PID_Packet><AU MID>
2)<Next_ES PID_Packet><DI = 1><New AU Start>
 
DI-Discontinuity Indicator
 
 
If its case 2 then Demuxer has to Reject the first packet ,but if its case 1
then Demuxer must accept both the Packets.
 
 
Thanks
Mohit
