Abstract

Disclosed herein are techniques to provide a unified display stream for multiple modes of a display specification. The display stream can include a link layer control protocol packet comprising link control information inserted between a set number of packets comprising display data. A packet can comprise indications of display data for a single stream or multiple streams.
