    Abstract: Technologies for end of frame marking and detection in streaming digital media content include a source computing device communicatively coupled to a destination computing device. The source computing device is configured to encode a frame of digital media content and insert an end of frame marker into a transport stream header of a network packet that includes an encoded payload corresponding to a chunk of data of the frame of digital media content. The destination computing device is configured to de-packetize received network packets and parse the transport stream headers of the received network packets to determine whether the network packet corresponds to an end of frame of the frame of digital media content. The destination computing device is further configured to transmit the encoded payloads of the received network packets to a decoder in response to a determination that the end of frame network packet has been received. Other embodiments are described and claimed.

    Abstract: Technologies for streaming device role reversal include a source computing device and a destination computing device coupled via a communication channel. The source computing device and destination computing device are each configured to support role reversal. In other words, the source computing device and the destination computing device are each capable of switching between receiving and transmitting digital media content over the established communication channel. The source computing device is configured to initiate the role reversal, pause transmit functionality of the source computing device, and enable receive functionality of the source computing device. The destination computing device is configured to receive a role reversal indication from the source computing device, locally process the content, transmit a content stream to the source computing device, and display the content stream on an output device of the source computing device. Other embodiments are described and claimed herein.

    Abstract: Source devices are provided that increase quality of displayed images by dynamically integrating higher fidelity update frames into a base stream encoded using an encoding technique (e.g., chroma-subsampling and/or another lossless encoding technique). Use of base image frames enables backward compatibility with existing technology and serves as a baseline for bandwidth scaling. The fidelity update frames may include raw image data, lossy, or losslessly compressed image data, and/or additional subsampled image data. The image data included in the fidelity update frames may apply to the entire base image frame or a portion thereof. The fidelity update frames may include incremental data or complete, high fidelity image data for a portion of an entire image. The source devices may store and implement fidelity management policies that control operation of the devices to balance resource consumption against fidelity to meet the needs of specific operational environments.

    Abstract: Technologies for location-dependent wireless speaker configuration include a mobile computing device wirelessly coupled to a plurality of speakers. The mobile computing device is configured to determine a location of and assign a location indicator to each of the speakers based on the determined locations. The location indicator identifies a location of each speaker relative to the other speakers such that the mobile computing device can generate an audio stream for each of the speakers based on the assigned location indicator and transmit each of the generated audio streams to a corresponding one of the speakers. Other embodiments are described and claimed herein.

    Abstract: Methods and apparatus for implementing a mode-switch protocol and mechanism for hybrid wireless display system with screencasting and native graphics throwing. Under a Mircast implementation, A Wi-Fi Direct (WFD) link is established between WFD source and sink devices, with the WFD source device configured to operate as a Miracast source that streams Miracast content to a Miracast sink that is configured to operate on the WFD sink device using a Miracast mode. The WFD source and sink devices are respectively configured as a native graphics thrower and catcher and support operation in a native graphics throwing mode, wherein the WFD source devices throw at least one of native graphics commands and native graphics content to the WFD sink device. In response to detection that Miracast content has been selected to be played on the WFD source device, the operating mode is switched to the Miracast mode. The mode may also be automatically or selectively switched back to the native graphics throwing mode. The techniques may also be applied to methods and apparatus that support other types of screencasting techniques and both wireless and wired links.
