Map estimation of multiple description encoded video transmitted over noisy channels

Robust decoding of a 3D-ESCOT bitstream transmitted over a noisy channel

“…Redundancy introduced by FEC and synchronisation markers may readily be used by JSC decoders, which have been successfully applied to several multimedia coders such as JPEG2000 [9], MPEG4 [10], H.263+ [11], H.264/AVC [12], or MPEG4/AAC [13]. These techniques have been applied only recently to DWT-based video coders [14]. The difficulty here comes from the very little amount of residual redundancy left by an entropy coder such as 3D-ESCOT [15] used in Vidwav (no entropy coder was considered in [14]).…”

The difficulty here comes from the very little amount of residual redundancy left by an entropy coder such as 3D-ESCOT [15] used in Vidwav (no entropy coder was considered in [14]). Moreover, a trellis-based decoding technique such as that used in [16] cannot be applied here, since 3D-ESCOT cannot be easily represented by a finite-state automaton (from which the trellis is derived) with a reasonable number of states.…”
