Claim Text:
1. A method, comprising: receiving a television video transport stream comprising video content associated with a particular television program, wherein the television video transport stream comprises focal-point metadata indicating at least one dynamic focus point for a zoom function in the video content, wherein the at least one dynamic focus point corresponds to a first sub-frame within a first frame of the video content and a second sub-frame within a second frame of the video content that is subsequent to the first frame; receiving focal-point input data indicating a zoom request for a particular dynamic focus point; and in response to receiving the focal-point input data: processing the video content, based on the focal-point metadata and the movement metadata, to generate a television video output signal, wherein the movement metadata comprises a motion vector indicating movement of the at least one focus point between the first frame and the second frame, and wherein processing the video content comprises: (a) generating, based on a comparison of the first sub-frame to the second sub-frame, the motion vector indicating movement of the at least one focus point between the first frame and the second frame, wherein the motion vector comprises both a directional component and a magnitude component; and (b) determining, based on the motion vector that indicates movement of the at least one dynamic focus point between the first frame and the second frame, a third subframe that corresponds to an estimated location of the dynamic focus point in a third frame of the video content that is subsequent to the second frame; and outputting the television video output signal to a graphic display, wherein the television video output signal comprises video content that is zoomed to the particular dynamic focus point in the first, second, and third frames of the video content.
