Abstract: Mechanisms are provided for replacing default advertisement streams in a media stream with replacement advertisement streams. User profile information is obtained for a particular user and/or device. A default advertisement stream is identified and replaced with advertisement streams selected using the user profile information. Timestamp information and sequence number information is maintained to allow uninterrupted delivery of the modified media stream while customizing media streams for particular users.

Abstract: A media feed is received and delineated into groups of pictures (GOPs) for processing into output media streams having different quality levels. The media feed needs only to be decoded once. The decoded stream is split along different paths based on resolution, and resized output media data is sent to multiple encoders and fragmenters to generate variants in bit rate and frame rate for each resolution. The generated variants may be maintained as fragments on shared storage. A particular stream corresponding to a particular variant can be reconstructed using the encoded fragments.

Abstract: A media stream is received and delineated into groups of pictures (GOPs). The GOPs are encoded and fragmented while a closed captioning monitoring system tracks fragment boundaries and adjusts closed captioning information including multi-language data and text tracks for correct presentation even in the presence of fragment boundary crossings. Encoded fragments with timing accurate closed captioning can be maintained as fragments on shared storage, even when randomly accessed.
