1. A method for video streaming, comprising:
receiving video streaming data from a wireless camera, wherein the wireless camera is in wireless communication with a vehicle;
identifying a stable video region in the video streaming data received from the wireless camera;
detecting stale video content in the video streaming data based on the stable video region;
conducting a video frame timestamp reconstruction, wherein conducting the video frame timestamp reconstruction includes determining a video frame presentation time of the video streaming data using a following equation: VPT=1/R, wherein R is the video framerate and VPT is the video frame presentation time of the video streaming data; and
in response to detecting the stale video content in the video streaming data, providing a notification to a vehicle occupant, via a display of the vehicle, wherein the notification is indicative that a video streamed in the display of the vehicle is stale.
