| Outline of Final Research Achievements |
In this study, universal variable-length data compression schemes for broadcasting are investigated.
Data compression for video distribution on network is formalized as lossy coding problem in the multiterminal information theory. This study investigates the one-to-many lossy source coding with side-information at decoders, and gives general bounds on the error exponents.
Further, the problem of distributed data compression for function computation is considered. For functions with certain structures, the optimal rate for computing those functions is characterized.
