Systems and methods for providing advertisements to point of presence devices including mapping different types of advertisement messages of respective content providers

A content distribution method comprising:

• receiving a plurality of in-band signals from respective content providers at a head end, wherein the plurality of in-band signals include video content;
• receiving at a placement opportunities information module of the head end a plurality of first messages associated respectively with the content providers, wherein the plurality of first messages are advertisement messages or program messages and have a plurality of respective formats, each of the advertisement messages or program messages having a first splice time parameter;
• mapping, at the head end, the plurality of first messages to a plurality of second messages by changing the first splice time parameter to a second splice time parameter, wherein the plurality of second messages have a same format, and wherein the same format is different than the plurality of respective formats of the first messages and is standardized for a plurality of point of presence devices, said plurality of first messages and said plurality of second messages each comprising a playout time;
• combining the second messages with the video content to generate combined signals at a combiner module of the headend;
• forwarding the combined signals to one or more insertion modules of a headend;
• determining, at the one or more insertion modules of the headend, when the second messages are to be played out based on the playout time;
• generating output signals at the one or more insertion modules based on the second time parameter and the playout time of the combined signals;
• and
• for each of the output signals, transmitting a non-streaming signal or a streaming signal from the headend to the plurality of point of presence devices.
