Techniques for dynamically changing characteristics of simulcast video streams in real-time multi-party video conferences. Once a video conference has been established for a plurality of participant devices, each participant device can provide a notification of its supported video communications characteristic(s) for sending simulcast video streams and receiving video streams. Having been provided such notification, the media server can determine video communications setting(s) and/or parameter(s) to be used by each participant device while sending simulcast video streams or receiving video streams based on the supported video communications characteristic(s) of the respective participant devices. In response to changes in conference, system, or network factors, the media server can request one or more of the participant devices to dynamically change the video communications setting(s) and/or parameter(s) used to send simulcast video streams or receive video streams to maintain acceptable levels of QoE at the respective participant devices.

A virtual collaboration system provides communication between a plurality of participants via a collaboration session that includes a corresponding plurality of participant devices. The collaboration session facilitates communication between the participant devices via a plurality of communication channels over which the participants communicate. For example, in some embodiments, the channels include one or more of a video channel, audio channel, or document sharing channel. A participant designates in which of the plurality of channels they will participate, and the designations are communicated to other participants. This provides a broader understanding of each participant's circumstances and ability to engage across the different channels with the plurality of participants.

Methods for synchronizing a client application user interface (UI) state of content of a client application on a client device corresponding with a host application on a host device are presented, the method including: receiving an update on the host application; transmitting a request for remote notification to the client device to synchronize the UI state of content of the client application responsive to receiving the event; displaying a notification corresponding with the request for remote notification on the client device indicating content is available to the client device; selecting the notification; launching the client application on the client device; transmitting a synchronizing request by the client device to the host device; enabling a synchronization mode of the host application; determining a host application UI state; transmitting content data associated with the UI state of the host application to the client device; and displaying the client application UI state based on the content data from the host device.

The present disclosure is generally related to integrating asynchronous text based and voice based communication between users on desktop and mobile devices with synchronous modes of communication, such as video or audio conferencing. More particularly, additional notifications, commands, and services may be provided to aid users to smoothly transition between different modes of operation, to adapt to varying conditions, and to reduce distraction caused by notifications.

Systems and methods to remotely store and provide telecast programs are provided. The method includes storing an exclusive first transcoded copy of a program in a first configuration for a first user along with multiple shared transcoded copies in respective multiple configurations. The method includes receiving a request from the first user to view the program, streaming the first transcoded copy, determining based on one or more criteria whether the first transcoded copy is supported, and continuing to stream the first transcoded copy or switching to a second transcoded copy from the multiple transcoded copies based on the criteria.

Embodiments of mechanisms for dynamic media content type streaming management for mobile devices are generally described herein. In some embodiments, the mobile device may receive selection input pertaining to generating output from a media file containing at least two of audio data, video data, and closed-captioning data, the selection input selecting at least one of audio, video, and closed-captioning to be output during play of the media content. In some embodiments, the mobile device may generate an audio output as a signal in response to the selection input including audio. In some embodiments, the mobile device may generate a video output as a signal in response to the selection input including video. In some embodiments, the mobile device may generate a closed-captioning output as a signal in response to selection input including closed-captioning.

A decoding complexity may be used to predict power consumption for receiving, decoding, and/or displaying multimedia content at a wireless transmit/receive unit (WTRU). The decoding complexity may be based on decoding complexity feedback received from a reference device, such as another WTRU. The decoding complexity feedback may be based on measurements performed at the reference device for receiving decoding, and/or displaying the multimedia content. A content providing device may indicate the decoding complexity of requested media content to a WTRU, or another network entity. The decoding complexity may be indicated in a streaming protocol or file associated with the media content. The WTRU, or other network entity, may use the decoding complexity determine its preferences regarding transmission of the media content. The content providing device may determine whether to transmit the media content based on the decoding complexity and/or the preferences of the WTRU or other network entity.

An example embodiment may involve determining that a client device (such as a smartphone, tablet, or in-automobile audio device) is in an automobile and that the client device has access to a playlist of audio content. Possibly based on the client device being in the automobile and having access to the playlist of audio content, the client device may request a stream of the audio content. As a consequence of making the request, the client device may receive the stream of the audio content and begin audible playout of the audio content.

Aspects of the subject disclosure may include, for example, a method that obtains consumption information for each of a group of communication devices associated with a user. A data plan is identified that is applicable to a communication device of the group of communication devices, and a group of media content is identified for the user based on the consumption information. The media content is provided to the communication device at a bit rate that varies according to the data plan. Other embodiments are disclosed.

In various examples, the decoding and upscaling capabilities of a client device are analyzed to determine encoding parameters and operations used by a content streaming server to generate encoded video streams. The quality of the upscaled content of the client device may be monitored by the streaming servers such that the encoding parameters may be updated based on the monitored quality. In this way, the encoding operations of one or more streaming servers may be more effectively matched to the decoding and upscaling abilities of one or more client devise such that an increased number of client devices may be served by the streaming servers.
