1. A system, comprising:
circuitry configured to:
acquire a video stream to be transmitted to an electronic device;
determine aspect ratio information associated with content, wherein the video stream includes the content;
determine, based on the aspect ratio information, a change in an aspect ratio of the content, wherein
the change in the aspect ratio is from a first value at a first timestamp to a second value at a second timestamp for a duration of the content; and
signal information indicative of the determined change to the electronic device, wherein the signal information comprises:
a flag that is set to true to indicate the change in the aspect ratio of the content,
the second value of the aspect ratio, and
timing information that includes the second timestamp at which the first value of the aspect ratio changes to the second value of the aspect ratio.
