Claim:
1. A method implemented by one or more computing devices, comprising: receiving, by the one or more computing devices, metadata associated with an advertisement in a transport signal stream from a first system, the metadata identifying a specified frame of the transport signal stream corresponding to a point in time of the advertisement; responsive to determining, by the one or more computing devices, that the transport signal stream is operating at a first frame rate, instructing the first system, by the one or more computing devices, to insert a first marker into the specified frame of the transport signal stream, the first marker identifying the point in time of the advertisement for the first frame rate; responsive to determining, by the one or more computing devices, that the transport signal stream is operating at a second frame rate differing from the first frame rate, instructing the first system, by the one or more computing devices, to insert a second marker differing from the first marker into the specified frame of the transport signal stream, the second marker identifying the point in time of the advertisement for the second frame rate; receiving, by the one or more computing devices, data from a viewing system; detecting, by the one or more computing devices, one of the first marker and the second marker in the data; identifying, by the one or more computing devices, one of the first marker and the second marker as the specified frame of the transport signal stream played by the viewing system; and mapping, by the one or more computing devices, one of the first marker and the second marker to the identified point in time of the advertisement.
