Abstract: A method for sharing content during a virtual 3D video conference, the method may include inviting multiple participants to join a virtual 3D video conference; creating a shared folder dedicated for storing shared content items, wherein the shared content is accessible during at least during the virtual 3D video conference; enabling access, to the multiple participants, to the shared folder; wherein the access is governed by one or more access control rule; and conducting the virtual 3D video conference; wherein the conducting comprises sharing at least one of the content items.

Abstract: Technologies are generally described for providing real-time or recorded content along with customized content augmentation stream to enhance a user's experience of the content. A content provider may receive captured feedback from multiple users and select and aggregate a subset of the received feedback based on preferences and emotional state of a user to be presented with the content. The aggregated feedbacks may be customized for the user and delivered as content augmentation stream along with the content to the user.

Abstract: Apparatus for rating download events is described. The apparatus includes a network interface and a processor. The processor, via the interface, monitors one or more download events in which content is downloaded by one or more users. In response to the monitoring, the processor identifies at least one quantitative property of the download events. Based on the property, the processor assigns rating to the download events that is indicative of an estimated user-perceived quality of the download events. The processor then generates an output indicative of the rating. Other embodiments are also described.

Abstract: A method includes monitoring a media stream that is streamed over a network at a given media bit-rate in a sequence of traffic bursts. Respective data volumes of one or more traffic bursts of the sequence are estimated, and the given media bit-rate is derived from the estimated data volumes.

Abstract: System, device, and method of cellular congestion management without cell awareness. A system defines applications as important or non-important. The system measures and monitors parameters related to cellular traffic, and remotely generates an estimate that a first User Equipment (UE) is experiencing cellular traffic congestion. A Deep Packet Inspection (DPI) Engine determines that the first UE is utilizing a first communication flow associated with an Important Application, and is also utilizing a second communication flow associated with a Non-Important Application. Filtering pass-through bitrate limits are enforced, selectively and remotely, on communication flows of the first UE, by enforcing a reduced bitrate limit on the second communication flow that is associated with a Non-Important Application, and by not enforcing a reduced bitrate limit on the first communication flow that is associated with an Important Application.

Abstract: A method for conducting a virtual three dimensional (3D) video conference between multiple participants, the method may include receiving by a user device of a first participant of the virtual 3D video conference, reference second participant 3D representation information for generating a second participant 3D representation under different constraints. The different constraints include at least one out of (a) a touch up constraint, (b) a makeup constraint, and (c) one or more circumstances constraint.

Abstract: Described embodiments include a system that includes a network interface and a processor. The network interface is configured to receive, at a first time, a packet transmitted from a source communication terminal over a communication network en route to a target communication terminal, before the packet passes through a particular portion of the communication network, and to receive the packet at a second time, after the packet has passed through the particular portion of the communication network. The processor is configured to delay the packet, subsequently to the packet being received at the second time, by a delay duration that is a decreasing function of a duration between the first time and the second time, and to send the delayed packet, subsequently, via the network interface, en route to the target communication terminal. Other embodiments are also described.
