Abstract: Provided are methods and streaming servers for segmenting multiple received content streams, and for aligning created segments of received content stream at a master server with segments of the received content streams created by a slave server. An example method performed at a streaming server of segmenting at least two received content streams is provided. The method comprises identifying a current boundary point for each of the at least two received content streams indicating where the respective content stream can be segmented, determining whether an identifier for a segment is included in a segment information database at the streaming server, the identified segment having a starting point corresponding to a timestamp of the identified current boundary point, and if so segmenting the received content stream, for which the segment identifier was included in the segment information database, at the timestamp and including the segment identifier with the segmented stream.
