    Abstract: A device implementing a system for multiway audio-video conferencing includes a processor configured to receive, from a first device, indication of a first channel and a second channel for communicating content for an audio-video conference session. The first channel and the second channel correspond to different types of communication interfaces. The processor is further configured to receive, from the first device, a first request to subscribe to a first content stream for the audio-video conference session via the first channel, and to subscribe to a second content stream for the audio-video conference session via the second channel, and in response to receiving the first request, forward, to the first device, the first content stream via the first channel.

    Abstract: When direct communication between devices, such as via Bluetooth, is unavailable, a communication protocol is used by an initiating communication device and/or a recipient communication device to establish a communication session via a cloud-based relay server. This communication protocol efficiently allocates (or binds) the initiating communication device, the recipient communication device, and the relay server together for the communication session. The communication protocol may include handshaking messages that specify a transport type and channel used for connections in the communication session, as well as an address of the relay server. After the communication session is confirmed, the communication protocol allows the initiating communication device and the recipient communication device to share messages even when physically separated from each other.

    Abstract: When direct communication, such as via Bluetooth, is unavailable, a communication protocol is used by an initiating communication device and/or a recipient communication device to establish a communication session via a cloud-based relay server. Establishing the communication session, such as a phone call or video streaming, includes setting up at least a first connection or link between the initiating communication device and the relay server, and at least a second connection or link between the relay server and the recipient communication device. Transports and interfaces for the first link and the second link may be selected independently of each other, and at least one of transports and interfaces for the first link and the second link may differ, e.g., the communication session may include asymmetric transport.

    Abstract: Apparatus and methods to evaluate connectivity between a primary device and a secondary device to support a connection for a real-time application to a remote device are disclosed. The primary device receives a connection request from the remote device and sends invitations to one or more secondary devices to connect with the remote device, the invitations sent through a first communication path. A secondary device that receives the invitation sends a connectivity evaluation packet to the primary device through a second communication path. When a connectivity response is received from the primary device through the second communication path and a user accepts the invitation, the secondary device sends an invitation response to the primary device and subsequently establishes a connection to the primary device through the second communication path. In some embodiments, the first communication path includes a cloud-based server that provides a guaranteed delivery message service.

    Abstract: A unified message delivery between multiple devices is disclosed. Sending messages through a local communications link, such as but not limited to at least one of a Bluetooth connection and a peer-to-peer WiFi connection, can lead to faster transmission times and reduced server load. When the local communications link is unavailable or not suitable, the messages can be sent through a network and a push server. In some examples, messages can be sent through both the local communications link and through the network and the push server. Duplicates of a received message can be avoided by utilizing indicators. In some examples, one or more devices can include queue(s) to ensure ordered delivery of a plurality of messages when a local communications link and network connection become unavailable.

    Abstract: Coded video data may be transmitted between an encoder and a decoder using multiple FEC codes and/or packets for error detection and correction. Only a subset of the FEC packets need be transmitted between the encoder and decoder. The FEC packets of each FEC group may take, as inputs, data packets of a current FEC group and also an untransmitted FEC packet of a preceding FEC group. Due to relationships among the FEC packets, when transmission errors arise and data packets are lost, there remain opportunities for a decoder to recover lost data packets from earlier-received FEC groups when later-received FEC groups are decoded. This opportunity to recover data packets from earlier FEC groups may be useful in video coding and other systems, in which later-received data often cannot be decoded unless earlier-received data is decoded properly.

    Abstract translation: 可以在编码器和解码器之间使用多个用于错误检测和校正的FEC码和/或包进行编码的视频数据。 只有FEC数据包的一部分需要在编码器和解码器之间传输。 每个FEC组的FEC分组可以采用当前FEC组的数据分组和前一个FEC组的未发送FEC分组的输入。 由于FEC分组之间的关系，当传输错误出现并且数据分组丢失时，当稍后接收的FEC组被解码时，解码器仍然有机会恢复来自早先接收的FEC组的丢失的数据分组。 从先前的FEC组恢复数据分组的机会在视频编码和其他系统中可能是有用的，其中后期接收的数据通常不能被解码，除非先前接收到的数据被正确解码。
