Abstract
A data structure, such as a digital television signal, includes (a) a video stream representing a picture and (b) auxiliary information, such as a closed caption stream. In one embodiment, the picture has special content that is not visible when a decoder correctly processes the auxiliary information. When an error occurs in the decoder processing, the special content becomes visible, thereby indicating the existence of the error to an observer of the rendered picture. In another embodiment, the video stream represents a sequence of time-varying pictures that provides a temporal reference for characterizing the relative timing of the decoder's processing of the auxiliary information.
