Methods, systems, and devices for adjusting streaming video field-of-view in accordance with client device commands
Methods, systems, and devices are provided for enabling client-controlled adjustments in the Field-of-View (FOV) of streaming video content principally through changes in server encoding parameters. In various embodiments the method includes the step or process of receiving, at a client media receiver, an encoded video stream transmitted from a streaming media server over a communications network. The encoded video stream is processed, at the client media receiver, to generate a video output signal for presentation on a display device associated with the client media receiver. The client media receiver monitors for user input modifying a FOV of the video output signal. When receiving user input modifying the FOV of the video output signal, the client media receiver then transmits a FOV modification command to the streaming media server to modify a FOV of the encoded video stream in accordance with the user input.
