Energy-efficient transmission of content over a wireless connection

Abstract

Energy efficient transmission of content can be provided using a variety of techniques. In an example technique, portions of content can be transmitted from a first computing device to a second computing device for display. A wireless radio of the first computing device can be placed into a low power mode between transmissions of the portions of content. In another example technique, one or more portions of content can be decoded, displayed, encoded, and transmitted by a first computing device for mirroring on a second computing device. One or more other portions of the content can be transmitted in encoded format to the second device without being decoded and displayed by the first device. In another example technique, a wireless radio of a first device can be placed into a low power mode in between transmission of commands to a second computing device to control content.
