Appl. No.:

16/503010

Inventors:

- Menlo Park CA, US
Bret Lorimore - Seattle WA, US
Shyam Sadhwani - Bellevue WA, US
Chi Wang Ho - Redmond WA, US

International Classification:

H04L 29/06
H04N 7/14

Abstract:

Systems, methods, and non-transitory computer-readable media can identify a set of participants in a group video call, wherein each participant is associated with an uplink capacity and a downlink capacity, and the set of participants includes a set of sender participants and a set of subscriber participants. For a first sender participant of the set of sender participants, one or more video stream layers to be uploaded by the first sender participant are determined based on downlink capacities of one or more subscriber participants of the set of subscriber participants. Each subscriber participant of the one or more subscriber participants is assigned to receive one video stream layer of the one or more video stream layers to be uploaded by the first sender participant.

H04N 7/15
G06K 9/00

Abstract:

In one embodiment, a computer server machine receives, from one or more client devices, one or more video streams associated with a video session associated with one or more users. The one or more users are respectively associated with each client device. The computer server machine analyzes the one or more video streams to identify an interesting event and generates a marker for the one or more video streams based on a time associated with the identified interesting event. The computer server machine sends information regarding the marker to the one or more client devices.

H04L 29/06
H04N 7/15

Abstract:

In one embodiment, a computer server machine maintains a persistent real-time group chatroom comprising one or more participants. At any given time, zero or more participants are active in the group chatroom. The computer server machine receives one or more video streams associated with a video session associated with one or more users. The video streams are communicated from one or more client devices with each client device respectively associated with the one or more users. The computer server machine provides a notification to one or more non-active participants, wherein the one or more non-active participants are not active in the persistent real-time group chatroom.

H04L 12/58
H04L 29/08

Abstract:

Techniques for providing multi-modal multi-party calling include receiving a join request at a multiway server (MWS) from a first client, the join request identifying a second client; sending a call invitation to the second client from the MWS; receiving a connection from the second client to the MWS; receiving a first media status from one of the first client or the second client while the first client and the second client are in a peer-to-peer mode; and forwarding the first media status to the other of the first client or the second client. Other embodiments are described and claimed.

International Classification:

G06F 17/30

Abstract:

A sequence of configuration-delta messages from a configuration manager of a replication graph established for replicating state information of an application is received at a particular node of the graph. Representations of the messages are stored in a local configuration change repository. Using the repository, the node identifies neighbor source nodes and destination nodes of the graph. Subsequent to receiving a particular configuration-delta message indicating that a neighbor source node has been removed from the graph, a different source node is identified by the particular node, and a request is sent to the different source node to transmit a set of state transition messages pertaining to the application.
