Common Mezzanine Distribution Format (CMZF): For ABR TV Distribution

Pay TV service providers need a way to re-use their extensive multicast MPEG-2 TS based infrastructure with scalable and reliable workflows for Ad Insertion and Fast Channel Change for managed (and OTT) ABR TV services. — Recent industry developments provide Common Media Application Format (CMAF) as a normalized playout format for efficient storage and distribution. CMZF proposes carriage of CMAF (ISOBMFF) fragments over MPEG-2 TS streams. — Video can be packaged in CMZF using existing workflows, and stored securely in origins and caches. The desired final CMAF (and HLS/DASH/SS) format is generated as needed via a simple container transformation in the gateway or STB without the need for re-encryption.
