Although most of the proposals for implementing motion-compensated temporal filtering (MCTF) schemes are based on the wavelet transform, in this paper, we propose an MCTF framework based on the discrete cosine transform (DCT).
Using DCT decimat[...]

In this paper, we present a two-stage forward error correction (FEC) scheme with an enhanced link-layer protocol especially for multimedia data transmission over wireless LANs.
At the application layer, packet-level FEC (stage-one) is added acr[...]

This paper addresses the efficient adaptation of encrypted scalable video content (H.264/SVC).
RTP-based in-network adaptation schemes on a media aware network element (MANE) in an IPTV and VoD scenario are considered.
Two basic alternatives t[...]
