Query: On Quantizer Design to Exploit Common Information in Layered Coding of
  Vector Sources   This paper studies a layered coding framework with a relaxed hierarchical
structure. Advances in wired/wireless communication and consumer electronic
devices have created a requirement for serving the same content at different
quality levels. The key challenge is to optimally encode all the required
quality levels with efficient usage of storage and networking resources. The
approach to store and transmit independent copies for every required quality
level is highly wasteful in resources. Alternatively, conventional scalable
coding has inherent loss due to its structure. This paper studies a layered
coding framework with a relaxed hierarchical structure to transmit information
common to different quality levels along with individual bit streams for each
quality level. The flexibility of sharing only a properly selected subset of
information from a lower quality level with the higher quality level, enables
achieving operating points between conventional scalable coding and independent
coding, to control the layered coding penalty. Jointly designing common and
individual layers' coders overcomes the limitations of conventional scalable
coding and non-scalable coding, by providing the flexibility of transmitting
common and individual bit-streams for different quality levels. It extracts the
common information between different quality levels with negligible performance
penalty. Simulation results for practically important sources, confirm the
superiority of the work.
