Systems and methodologies for employing bidirectionally decodable Wyner-Ziv video coding (BDWZVC) are described herein. BDWZVC can be used to generate M-frames, which have multiple reference frames at an encoder and can be forward and backward decodable. For example, optimal Lagrangian multipliers ...
