Common Media Server Data
CMSD aims to standardize how every media server (intermediate and origin) can communicate data with each media object response and have it received and processed consistently by every intermediate server and player. Using CMSD's specification will increase efficiency and performance in distributing media workflows. Consequently, improve the quality of experience (QoE) for end-users.
You can download a copy of CMSD in CTA-WAVE's Common Media Server Data (CMSD) and follow the work in the CMSD public repository.
