Abstract

Systems and methods for content and program type detection, including identification of true boundaries between content segments. A broadcast provider sends a broadcast as an encoded stream. During a switch between content types, an automation system sends identifying metadata indicative of an approximate boundary between content types. A mediacast generation system receives the encoded stream of content and metadata, processes the metadata, time corrects the metadata, and slices the content on the exact boundary where the content change occurs. The mediacast generation system decodes an audio stream directly into Waveform Audio File Format (WAVE) while using an envelope follower to measure amplitude. When the system detects a metadata marker, an analyzer may look inside a buffered time window. The WAVE data may be analyzed to look for a period most likely to be the true boundary or split point between content segments. The content may then be split up on the new true boundary.
