    摘要： An end-to-end multimedia streaming system can include a streaming server and a destination. The streaming server includes a content source, which sends multiple description coding-encoded content over a plurality of paths to the destination. The destination includes an aggregator for aggregating the descriptions from the multiple paths, decoding and recombining them to recover the content. A feedback sender at the destination generates traffic performance variables based on the channel conditions of the multiple paths, and sends these variables to a feedback receiver at the streaming server. The feedback receiver utilizes the feedback information to make adjustments to the transmissions of the content, and to synchronize the transmissions over the multiple paths.

    摘要： A sink device in a Wireless Display (WD) system may send performance information feedback to a source device to adjust media data processing at the source device. The performance information feedback may include performance indicators of the WD system that are capable of being measured or calculated at the sink device based on received media data or request to adjust the transmission of media data. For example, the performance information feedback may include one or more of round trip delay, delay jitter, packet loss ratio, error distribution, and received signal strength indication (RSSI). The feedback channel may be piggybacked on a reverse channel architecture referred to as the User Input Back Channel (UIBC) implemented between the source device and the sink device.

    摘要： A method, system, and computer program product for providing feedback over a multiple path network is provided. A first device sends a transmissions to a second device over at least two different paths of the network. Using information collected as a result of receiving the transmissions, the second device aggregates data regarding the performance of each of the paths together into a feedback message. The second device then sends this feedback message to the first device over one path of the network. The first device uses the data in the feedback message in its calculations for determining the relative performance of each path. The amount of traffic sent along each path is adjusted as appropriate, based on these calculations.

    摘要： As part of a communication session, a wireless source device can transmit audio and video data to a wireless sink device, and the wireless sink device can transmit user input data received at the wireless sink device back to the wireless source device. In this manner, a user of the wireless sink device can control the wireless source device and control the content that is being transmitted from the wireless source device to the wireless sink device. The input data received at the wireless sink device can have associated coordinate information that is scaled or normalized by either the wireless sink device or the wireless source device.

    摘要： This disclosure relates to techniques to establish a multicast communication session between a source device and multiple sink devices in a Wireless Display (WD) system. Two or more sink devices may be interested in receiving the same media data from the source device. According to the techniques, the source device establishes a multicast session with the sink devices in the WD system, and sends a single copy of multicast media data for the multicast session to the interested sink devices using a receiving multicast port. The source device selects a receiving multicast port number as a destination identifier for each multicast session. The sink devices interested in receiving the media data of a given multicast session bind on the receiving multicast port for the multicast session. This disclosure describes several exemplary multicast subscription procedures to ensure correct binding on the receiving multicast port at each of the sink devices.
