Abstract: A computing system that identifies a media stream that a media client is processing for presentation determines which frame format of the media stream the media client is processing for presentation. And the computing system uses that determined frame format as a basis to facilitate dynamic content modification. For instance, based on then determined frame format, the computing system could work to ensure that replacement or overlay content that the media client obtains to facilitate dynamic content modification of the media stream is of that determined frame format. Further or alternatively, based on the determined frame format, the computing system could work to ensure that the media client gets provisioned with reference fingerprints of that particular frame format of the media stream, for use to facilitate client-side fingerprint matching to confirm that the media stream continues to be identified media stream.
