Abstract
Digital content encoded in a media file format may be presented by accessing the media file, reading parameters that describe the content, and processing the media file using the encoded parameters to “play” or generate output. Although the media file format may have multiple optional extensions, the media file generally includes one or more frames. Each frame may include a synchronized frame with the synchronized frame having a synchronized header, a video format indicator, an audio format indicator, a width indicator, a height indicator, a frame rate index, and a payload. Although the digital content may include different types and formats, the parameters used in the media file may be used to describe the digital content so that it may be processed independent of the underlying algorithm used. For example, multiple channels of audio signals may be described.
