Abstract
Methods, apparatus, systems and articles of manufacture are disclosed for delivering extended payloads with composite watermarks. Examples disclosed herein embed a first watermark into a media stream in accordance with a first watermark technology, where the first watermark includes a first indicator bit and a first payload. Disclosed examples also embed a second watermark into the media stream in accordance with a second watermark technology, where the second watermark includes a second indicator bit and a second payload. In some disclosed examples, the first indicator bit and the second indicator bit are to indicate whether the first payload and the second payload are to be combined when the first watermark and the second watermark are decoded.
