Abstract
A method for demultiplexing time-division multiplexed digital video data which originates from multiple sources. The video data is not indexed nor identified to the sources. A first set of digital video data representative of a first image is identified as representative video data of the first source. A second set of digital video data representative of a current image is then retrieved. A difference ratio is calculated using the representative digital video data and the current set of digital video data. If the difference ratio is above a threshold, a display query is prompted to a user to indicate the source. If the response is indicative with a new source, the current set of digital video data is stored to a second memory location associated with the second source and identified as a representative of the second source.
