Embodiment Construction

[0018] Embodiments relate to systems, methods and devices for optimizing video performance on wireless docks, and more particularly, systems, methods and devices for optimizing video performance in wireless docks with ultra-high definition displays.

[0019] In general, there is a need to provide wireless base capabilities for wireless devices. For example, one advantageous feature of a wireless dock may be the ability to display video from a wireless device with a relatively small screen (eg, a cell phone) on a large device's screen (eg, a high-definition television screen). In some aspects, displaying video from a cell phone on a television can be accomplished through the use of a wired connection, such as an HDMI (High Definition Multimedia Interface) cable. However, as cellular phones and other portable wireless electronic devices such as laptops, tablet computers, and others become smaller, it may be desirable to reduce the number of ports on these devices or eliminate as...

Abstract

The invention discloses a system and method to optimize video performance in a wireless-dock with an ultra-high definition display. According to the invention, methods, devices, and computer program products are provided for using raw bitstreams and lossless distributed source coded (DSC) video to optimize video performance in wireless dock with ultra-high definition displays. In one aspect, a method of transmitting a video stream from a transmitting device to a wireless video display is described. The method includes determining a resolution of the wireless video display and a native resolution of a video stream, as well as a connection speed between the transmitting device and the wireless video display. Based on this information, the method selects a video compression format, choosing between raw video, DSC video, and high-efficiency video coded video. The method further transmits the video stream in the selected video compression format from the transmitting device to the wireless video display.

Description

technical field [0001] The present application relates generally to optimizing video performance on wireless docks, and more particularly to systems, methods and devices for optimizing video performance in wireless docks with ultra high definition displays. Background technique [0002] As wireless devices become more advanced, the size of the wireless devices decreases while the functionality increases. Accordingly, there may be a need to be able to display information from a wireless device, such as video stored locally or streamed from a wider network, on an external display, such as a computer screen, television, or another external display. However, in some respects, the high resolution of video displays can cause bandwidth issues, as the bandwidth required to stream lossless video to the wireless display over the wireless communication network can exceed the transmission of the connection between the wireless device and the wireless display ability. Accordingly, ther...
