1. A method for inserting one or more local signals and for reallocating bandwidth during an inherent delay period associated with a changing from a first video stream to a second video stream in a digital television environment, the method comprising:

  • (a) receiving a first video stream that occupies a first bandwidth;

    (b) receiving a request for a second video stream that occupies a second bandwidth;

    (c) recognizing the inherent delay period associated with execution of the request for the second video stream, wherein the inherent delay period is the time to acquire and decode a digital video signal;

    (d) generating a request for a local signal, wherein the local signal is stored in memory;

    (e) inserting the local signal during the inherent delay period; and

    (f) reallocating the first bandwidth and at least a portion of the second bandwidth during the inherent delay period, such that data not associated with the first video stream or the second video stream may be received.
