Handoff Architectures Ahkd Protocols For Transmitting Compressed Multimedia Information In Mobile PCSs

A bstract Cont inuous med ia , e.g., video, t ha t are transmit ted in mobile personal communica t ion sy s t ems (PCSs) should be in t h e compressed f o r m a t , e.g., t he MPEG f o r m a t , in order t o reduce t h e bandwidth requirement. T h e corresponding handof f architectures and protocols are thus dif ferent f r o m t h e traditional ones, wh ich are f o r transm i t t i ng uncompressed med ia . In this paper, we present several handof f architectures and protocols t o resolve t h e associated handof f issues f o r transmit t ing compressed mu l t imed ia inforrnation.
