A novel universal bridge (UB) can handle and conduct multimedia multipoint conferences between a plurality of MREs and LEPs without using an MRM, an MCU and a gateway. Further, a UB can be configured to allocate and release resources dynamically according to the current needs of each conferee and the session.

Various embodiments may provide streaming service downlink assistance and/or uplink assistance mechanisms for a wireless device using attention (AT) commands exchanged between a modem processor of the wireless device and another processor of the wireless device. Various embodiments may include an AT command that is a bitrate recommendation action command including an indication of a stream identifier, an indication of a requested bitrate, and an indication of a direction. Various embodiments may include an AT response that is a bitrate recommendation response, the bitrate recommendation response including an indication of a stream identifier, an indication of a bitrate recommendation, and an indication of a direction.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating a video stream preview. One of the methods includes receiving, from a user device, a request for a video stream preview. A payload of data is transmitted from a session system to the user device over a network. A first measure of network transmission quality is determined based on a result of transmitting the payload to the user device over the network from the session system. A second measure of network transmission quality is determined for data transmitted over the network from a session host to the session system. A video stream preview is generated from an example video stream obtained from the user device by degrading the quality of the example video stream according to the first measure of network transmission quality and the second measure of network transmission quality. The video stream preview is displayed on the user device.

Embodiments are provided for receiving media content based on the user media preferences. An example implementation includes a one or more servers receiving data representing a guest list for an upcoming event corresponding to a first user account, the guest list indicating multiple guests corresponding to respective second user accounts of a second cloud service and querying one or more streaming media services for music preferences corresponding to the multiple guests. The one or more servers receive, from the one or more streaming media services, data representing respective music preferences corresponding to the multiple guests and generate a playlist of audio tracks based on the received respective music preferences corresponding to the multiple guests. During the event, the server(s) cause the playlist to be queued in a playback queue for playback by one or more playback devices of a particular media playback system registered with the first user account.

A system for intelligent multi-device content distribution based on associated internet protocol (IP) addressing, including: identifying, by a computer processor, first advertising content served to a first client device; identifying a first client device IP address associated with the first client device, where the first client device is linked to a household profile; submitting, to a content exchange service, a request for content placement opportunities; receiving content placement opportunities from the content exchange service, where one or more content placement opportunities identify at least a portion of a second client device IP address of a second client device; linking the second client device to the household profile; selecting second advertising content based on the first advertising content; and providing the second advertising content for the content placement opportunity to be displayed on the second client device.

A system and method is provided for performing lossless switching in a redundant multicast network. An exemplary method includes receiving a primary media stream and a redundant media stream over different forwarding network paths by network ports of a receiver communicatively coupled to an A/V device. Furthermore, the receiver outputs media data of the media streams to the A/V device to be presented thereon. In response to a control signal to switch the receiver to a new primary media stream, the method disconnected either the primary ort the redundant media streams from the respective network port of the receiver receiving that stream. Furthermore, the method includes controlling the disconnected network port to receive the new primary media stream and then outputting media data of the new primary media stream to the A/V device to be presented thereon.
