Disclosed is a system for generating a graphics window that is capable of
emulating enhanced video from a combined video and interactive content
stream. The set-top emulator can randomly access the combined video and
interactive content stream to provide an easy manner of randomly
accessing portions of the combined video and interactive stream for
quality control purposes. Random access allows selective viewing of the
enhanced video which saves time. Additionally, the combined video and
interactive content stream can be simultaneously viewed as it is being
produced to allow immediate feedback to an interactive television
producer.
