Scheduling of dataflow models within the Reconfigurable Video Coding framework
The upcoming Reconfigurable Video Coding (RVC) standard from MPEG (ISO/IEC SC29WG11) defines a library of coding tools to specify existing or new compressed video formats and deco...

Lower Bounds on the Rate-Distortion Function of Individual LDGM Codes
Abstract-- We consider lossy compression of a binary symmetric source by means of a low-density generator-matrix code. We derive two lower bounds on the rate distortion function wh...

Improved CAVLC for H.264/AVC Lossless Intra-Coding
Context-based adaptive variable length coding (CAVLC) for the H.264/advanced video coding (AVC) standard was originally designed for lossy video coding, and as such does not yield ...

Optimal Constellation for General Rectangular PAM/QAM with Arbitrary Code Mapping
Abstract— Recently the exact expression for the BER of rectangular QAM with arbitrary code mapping was obtained [1]. It is then natural to ask for the optimal constellation desig...
