摘要： A method, apparatus, system, and signal-bearing medium that in an embodiment detect that a first packet is not received, add a place holder for the first packet in a buffer, request retransmission of the first packet, and create an estimated packet based on a combination of a second packet previous to the first packet, a third packet following the first packet, and a fourth packet from a previous frame that is spatially corresponding to the first packet. In another embodiment, a method, apparatus, system, and signal-bearing medium are provided that send a encoded packet to a receiver, save the encoded packet in a bitstream, determine whether the encoded packet is lost, and when the encoded packet is lost, decode the bitstream with the lost packet omitted and insert a reconstructed frame associated with the lost packet into a reference frame storage. In another embodiment, when the encoded packet is lost, a decoder is run on a reference frame chosen as the last uncorrupted frame. In another embodiment, when the encoded packet is lost, the decoder is run on a frame chosen from a set of previously stored reference frames.

摘要： Some embodiments provide a method of combining multiple streams of data packets into a single combined stream in a manner that facilitates accurate estimation of bandwidth of a connection over a network between two devices. When combining the streams into the combined stream, the method associates a set of packets from a first stream and a reference packet from a second stream to form a longer sequence of packets in the combined stream. The method sends the combined stream from a first device to a second device so that the second device can estimate the bandwidth of the connection between the first and second devices based on the inter-arrival times of the packets in the sequence of packets.

摘要： A method and apparatus for adapting transmission to improve quality of service in a mobile wireless device that includes an application processor and a transceiver. An application service connection is established between the mobile wireless device and a remote device. The transceiver in the mobile wireless device monitors real time properties of a radio frequency access link that transports packets for the application service between the mobile wireless device and a wireless communication network. The transceiver provides local feedback to the application processor of updated values of the monitored real time properties. The application processor adjusts packet data generation and transmission in response to the updated values to manage quality of service for the application service connection. Packet data transmission adjustment includes active management of queues in the transceiver by the application processor, selectively dropping packets based on packet classifications and the local feedback information provided to the application processor.

摘要： Some embodiments use several different types of networks to relay several different types of media content among several different computing devices. The media content of some embodiments is data that a computing device can process in order to provide a presentation of the media content to a user of the device. Examples of types of such media content include audio data, video data, text data, picture data, game data, and/or other media data. In some embodiments, two different networks relay media content of two different types among multiple computing devices. Specifically, in some embodiments, a first network routes among the computing devices one type of media data content (e.g., game data), while a second network routes among the computing devices another type of media data content (e.g., audio and/or video data of game participants). The two networks differ in some embodiments based on their topology.

摘要： A first computing device distributes audio streams to several computing devices of participants in a communication session. Some embodiments establishes a star network with the first computing device as a central network hub for receiving audio streams from other computing devices, compositing the audio streams and distributing the composited audio streams to the other computing devices. Through the star network, the first computing device receives audio streams from the other computing devices. The first computing device generates at least two different composite audio streams for at least two different computing devices by (i) identifying a set of silent participants in the communication session, and (ii) eliminating redundant audio processing operations that produce the same composite audio streams for different computing devices because of the identified set of silent participants. The first computing device sends each computing device the composited audio stream for the device.

摘要： Some embodiments dynamically designate one of several network nodes as a network hub of a star network, at the start of a network communication session among the several network nodes that is facilitated by a mesh network and the star network. Some embodiments dynamically designate a new network hub when the previously designated network hub leaves the communication session, which continues among the other network nodes. Different embodiments use different techniques to dynamically designate the network hub of the star network. For instance, some embodiments use communications transmitted along the mesh network to dynamically identify the network hub at the start of the network communication session or after the departure of a previously designated network hub.

摘要： For a first device participating in a video communications session with a second device, some embodiments provide a method that receives sets of encoding features supported by each of one or more decoders of the second device. The method selects an encoder for the video communication session from several encoders available to the first device. The method selects a set of encoding features of the selected encoder based on the sets of encoding features received from the second device. The method transmits an encoded video bitstream to the second device along with information identifying the selected features in order for the second device to select a decoder to decode the bitstream.
