ABSTRACT:
A content distribution network includes a central content management system that acquires digital assets for distribution over the network to on-demand serving locations for on-demand delivery to customers. A digital asset includes a package of files. The files are processed prior to distribution from the central content management system to provide trick mode support. The content distribution network distributes the processed files from the central content management system to the serving locations. A method includes breaking up the digital asset at the central content management system into chunks, utilizing a pipelined distribution process between the central content management system and the serving locations for the digital asset chunks, and re-assembling the digital asset chunks at the serving locations.
