Estimating the term…
A method and apparatus for performing template-based prefix caching advantageously identifies common prefixes (i.e., initial video segments) in video titles, stores common prefixes only once in a prefix cache, and uses these common prefixes when serving requests for video content. This advantageously enables a prefix cache to scale to a large number of video titles, since the cache stores each common prefix only once. A new video title that uses an already existing prefix may be advantageously added without requiring additional storage in the prefix cache. Template-based prefix caching also advantageously reduces the bandwidth required to distribute prefixes when new titles are ingested into the system—if the required template is already available in the prefix cache, prefix-caching is enabled instantly for this title and no additional bandwidth is required to distribute the prefix.
A method for use in the delivery of video content comprised in and selected from a plurality of video titles, the method performed with use of a cache and comprising the steps of:

A method for use in the delivery of video content comprised in and selected from a plurality of video titles, the method performed with use of a cache and comprising the steps of:
An apparatus comprising a cache for use in the delivery of video content comprised in and selected from a plurality of video titles, the cache comprising data representative of one or more prefix templates, each of said prefix templates representing an initial portion of video content comprised in two or more of said video titles in said plurality of video titles and being associated with said two or more of said video titles, each of said prefix templates for use in said delivery of said video content.
