Methods and systems for generating motion vectors for re-encoding video signals are disclosed. The motion vector is determined by the sum of a base motion vector and a delta motion vector. In the case of no frame-skipping, the base motion vector is the incoming motion vector. In the case of frame skipping, the base motion vector is the sum of the motion vectors of the incoming signal since the last re-encoded frame and the current frame. The delta motion vector is optimized by a minimum Sum of the Absolute Difference by searching over a smaller area than if searching for a new motion vector without a delta motion vector. These methods and systems may be used to improve re-encoding digital video signals.
A method of re-encoding digital video from a previously encoded digital video having at least one input motion vector, the method comprising the steps of:
An apparatus for re-encoding digital video from a previously encoded digital video having at least one input motion vector, the apparatus comprising:
A computer-readable medium containing instructions for controlling a computer system to perform a method of operating a processor, the method comprising:
An apparatus for re-encoding digital video from a previously encoded digital video signal having at least one input motion vector, the apparatus comprising:
