摘要: A device implementing dynamic redundancy may include at least one processor configured to receive, from another device, packet reception data corresponding to video data previously provided for transmission from the device to the other device and determine, based at least in part on the packet reception data, an amount of redundancy to apply to video data provided for transmission to the other device. The at least one processor may be further configured to determine, based at least in part on the amount of redundancy, an encoding scheme for applying the redundancy to the video data. The at least one processor may be further configured to apply the amount of redundancy to the video data based at least in part on the encoding scheme to generate redundant data items and provide the video data and the redundant data items for transmission to the other device.

摘要: A device implementing a system for packet loss management may include a memory and at least one processor configured to identify a plurality of categories of packets provided for transmission to an electronic device. The at least one processor may be further configured to determine a respective packet loss value for a respective category of the plurality of categories of packets. The at least one processor may be further configured to identify a particular category of the plurality of categories of packets for which the determined respective packet loss value satisfies a packet loss condition. The at least one processor may be further configured to adjust subsequent transmission of packets in the particular category of packets based at least in part on the packet loss condition being satisfied by the determined respective packet loss value for the particular category of packets.

摘要: A device implementing a system for multipath connection management may include first and second local communication interfaces, and a processor configured to establish a primary connection for communicating between the first local communication interface and a first remote communication interface of an other device, and a secondary connection for communicating between the second local communication interface and a second remote communication interface. The processor may be configured to transmit application and control data over the primary connection and concurrently transmit a copy of control data over the secondary connection. The processor may be configured to determine that a degradation of the quality of the primary connection is attributable to the other device. The processor may be configured to switch the secondary connection to the first local communication interface and the second remote communication interface. The processor may be configured to transmit a copy of the application and control data over the secondary connection.

摘要: A method and apparatus of a device that uses a video jitter buffer to buffer the video frames for a received video stream is described. The device uses the video jitter buffer to estimate the delay variability of the frames and pick a target delay that will help harmonize the playback with minimal loss and delay. This is achieved by estimating the delay spread, which is the result of performing statistical analysis of the measured lags of the video frames received. The video jitter buffer provides target delay recommendation and reference frame information to the video player in order to anchor the playback and schedule the frames presentation time.
