Abstract
A method and apparatus are provided for communicating HBI user information in digital television data streams via a generic syntax. The syntax allows the digital transport of virtually any type of user data that may be carried in the HBI or overscan portion of an analog television signal. A pixel generator is used to insert HBI data into a digital video signal using information provided in the user portion of the digital data stream. The syntax provides the pixel generator with the start time of the first symbol, the number of pixels per symbol, the high and low levels to insert, the fraction of the symbol time that is transition time, the number of symbols to insert and the first frame line number on which to insert the data.
