Systems and methods to identify video content types

A content delivery system, comprising:

• at least one communications port communicatively coupleable to receive an electronic mediacast source signal from a broadcaster or a Webcaster, the electronic mediacast source signal at least including a plurality of replaceable content segments comprising image content data and a plurality of non-replaceable content segments comprising image content data;
• at least one nontransitory processor-readable medium which stores a number of processor-executable instructions;
• and
• at least one processor communicatively coupled to the at least one communications port and communicatively coupled to the at least one nontransitory processor-readable medium to execute the processor-executable instructions, which execution causes the at least one processor to:
• receive the electronic mediacast source signal from the broadcaster or the Webcaster;
• for each of a number of the content segments of the electronic mediacast source signal, detect whether the respective content is non-replaceable or replaceable, whereby the at least one processor:
• reviews only a defined region of a rendering surface of the image content data for a presence or absence of at least one defined graphic element contained within at least one of the replaceable content segments or the non-replaceable content segments to determine whether a portion of the received electronic mediacast source signal corresponds to a non-replaceable content segment, which comprises one or more sections of non-replaceable content material comprising a plurality of entire frames of image content data that are entirely non-replaceable, or a replaceable content segment, which comprises one or more sections of replaceable content material comprising a plurality of entire frames of image content data that are entirely replaceable, based on at least one of a presence or an absence of the defined graphic element, wherein the defined region is a pre-defined detection region that comprises only a portion of the spatial rendering surface that is smaller than the entire spatial rendering surface, and the defined graphic element is a pre-defined graphic element;
• retains content segments of the received electronic mediacast source signal identified as being non-replaceable content segments;
• and
• replaces one or more sections of the replaceable content material within each of at least some of the content segments of the received electronic mediacast source signal identified as being replaceable with a respective one or more sections of replacement content material within at least one replacement content segment, wherein the one or more sections of the replacement content material has a duration that is one of greater than or less than a duration of the one or more sections of the replaceable content material replaced by the replacement content material.
