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 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： Techniques are disclosed for coding video data in which frames from a video source are partitioned into a plurality of tiles of common size, and the tiles are coded as a virtual video sequence according to motion-compensated prediction, each tile treated as having respective temporal location of the virtual video sequence. The coding scheme permits relative allocation of coding resources to tiles that are likely to have greater significance in a video coding session, which may lead to certain tiles that have low complexity or low motion content to be skipped during coding of the tiles for select source frames. Moreover, coding of the tiles may be ordered to achieve low coding latencies during a coding session.

摘要： A device implementing the subject technology may include at least one processor configured to receive an indication of a task being performed at an other device. The at least one processor is further configured to perform, in response to receipt of the indication, one or more preliminary operations in anticipation of receiving a handoff of the task. The at least one processor is further configured to receive, after performing the one or more preliminary operations, a notification that the task is being handed off. The at least one processor is further configured to receive the handoff of the task from the other device. The at least one processor is further configured to continue to perform the task based at least in part on the one or more preliminary operations that were performed prior to receiving the notification that the task is being handed off.

摘要： Systems and processes for providing textual representations for a communication session are provided. For example, at least one audio input is received at an electronic device, wherein each audio input of the at least one audio input is associated with a respective priority level. A priority level of an audio input detected at a microphone of the electronic device is determined, wherein a highest priority level among the determined priority level and each received priority level corresponding to the at least one audio input is identified. A textual representation of a respective audio input corresponding to the identified highest priority level is obtained, wherein the obtained textual representation is displayed on a display of the electronic device.

摘要： Aspects of the subject technology include transmitting, by a first device, an advertisement message corresponding to a communications session the first device is participating in with at least a second device. The first device may receive, during the communications session, a communications session control message generated by a third device. The communications session control message may include information contained in the advertisement message. The first device may validate the third device based on the communications session control message and remove the first device from the communications session in response to successfully validating the third device.

摘要： The subject technology receives, at a local device, a requested camera format based on specifications of a display associated with a remote device. The remote device and the local device are devices participating in a video conference. The requested camera format includes a first resolution. Camera formats supported by a camera associated with the local device are determined. If a second resolution of a first camera format matches among the supported camera formats matches with the first resolution, the first camera format is selected for capturing the video stream by the camera. Otherwise, a second camera format among the supported camera formats is determined for capturing the video stream so as to maximize a field of view of the video stream relative to other camera formats supported by the camera.
