    "abstract": "A “Time Machine” has been developed which is capable of increasing, decreasing and/or shifting passages of time for television signals by at least 30 seconds each 1/2 hour period. This machine evolved from the Prime Image, Inc. “A/V Delay” product and is capable of changing time without changing the pitch (frequency) of the video or audio programming. This is accomplished by adding and subtracting packets of time. The process causes minimal to no degradation in the processed audio and video programming and can be accomplished in real time. The resultant signal is compatible with standard television signals.",
