Problems and Solutions for Multicast
•
Problem : Wireless Multicast environment
• Packet losses
• No Modulation & Coding scheme adaptation
• No retransmission
•
Solution : Forward Error Correction
•
Problem : FEC efficiency is low at “small size” (10KB) of
source block
• FEC need large numbers of source block to
recover well
•
Solution : Use DASH segments rather
than RTP frames
•DASH segment have at least 1 GoP
( about 30 frames )
•
Problem : DASH need file delivery
• MPEG-DASH uses HTTP but HTTP can not be
multicasted.
•
Solution : FLUTE for File Delivery
