Abstract: A method includes exchanging signaling between a first entity providing access by a user equipment to a video stream and a second entity through which the video stream passes prior to being delivered via wireless transmission to the user equipment, the second entity receiving video information corresponding to the video stream, the exchanged signaling associated with the video information received at the second entity. Responsive to the exchanged signaling, sending information from the first entity to the second entity to modify status at the second entity of at least a portion of the video information previously received at the second entity. Another method includes at the first entity, receiving from a second entity an indication the second entity is capable of accepting multiple resolutions of a video in the video stream. Responsive to the received indication, the first entity sends to the second entity multiple resolutions of the video.
