Abstract
Systems and methods for adaptive bitrate streaming of alternative streams of video encoded at resolution and sample aspect ratio combinations and maximum bitrates in accordance with embodiments of the invention are disclosed. In one embodiment of the invention, a source encoder configured to encode a source video stream as a plurality of alternative streams of video for playback on a playback device includes a processor configured to receive multimedia content including source video data having a primary resolution, a primary sample aspect ratio, and a primary frame rate and to encode the source video data as alternative streams of video, where the resolution and sample aspect ratio of at least one of the alternative streams of video are selected to have an aspect ratio that is the same as a predetermined display aspect ratio and at least one of the alternative streams is encoded at a maximum bitrate.
