Abstract: In video conferencing over a radio network, the radio equipment is a major power consumer especially in cellular networks such as LTE. In order to reduce the radio power consumption in video conferencing, it is important to introduce an enough radio inactive time. Several types of data buffering and bundling can be employed within a reasonable range of latency that doesn't significantly disrupt the real-time nature of video conferencing. In addition, the data transmission can be synchronized to the data reception in a controlled manner, which can result in an even longer radio inactive time and thus take advantage of radio power saving modes such as LTE C-DRX.
Abstract translation: 在无线电网络的视频会议中，无线电设备是主要的电力消费者，特别是在诸如LTE的蜂窝网络中。 为了降低视频会议中的无线电功耗，重要的是要引入足够的无线电时间。 几种类型的数据缓冲和捆绑可以在合理的延迟范围内使用，不会显着破坏视频会议的实时性质。 此外，可以以受控的方式将数据传输同步到数据接收，这可以导致更长的无线电时间，从而利用诸如LTE C-DRX之类的无线电节能模式。

Abstract: Systems and methods are presented for minimizing the suddenness and immediacy of changes to the video quality perceived by users due to bandwidth fluctuations and transitions between different bitrate streams. A method may include identifying an upcoming bitrate change in a bitstream and a nearest scene cut boundary from sync frame scene cut tags included in the bitstream. The method may include calculating whether waiting until the identified nearest scene cut boundary before changing the bitrate will cause the buffer to drop below a threshold. When the buffer is calculated to not drop below the threshold, the method may postpone the upcoming bitrate change until the identified nearest scene cut boundary.

Abstract: A method for adaptive audio codec selection during a communication session is disclosed. The method can include negotiating a set of audio codecs for use during the communication session. The method can further include defining multiple audio tiers. Each audio tier can be associated with a network condition and can define an audio codec from the set of audio codecs for use in the associated network condition. The method can also include using a first audio codec during the wireless communication session. The method can additionally include determining a changed network condition selecting a second audio codec by determining the audio tier corresponding to the changed network condition. The method can further include, in response to the changed network condition, switching from the first audio codec to a second audio codec that is defined by an audio tier having an associated network condition corresponding to the changed network condition.

Abstract: Computing devices may implement dynamic transitions from video messages to video communications. Video communication data for a video message may be received at a recipient device. The video communication data may be displayed as it is received, and recorded for subsequent playback. An indication of a selection to establish a video communication with the sender of the video message may be received, or an indication that display of the video communication is to be ceased may be received. If a video communication is to be established, then a video communication connection with the sender of the video message may be created so that subsequent video communication data may be sent via the established connection.

Abstract: Computing devices may implement dynamic detection of pause and resume for video communications. Video communication data may be capture at a participant device in a video communication. The video communication data may be evaluated to detect a pause or resume event for the transmission of the video communication data. Various types of video, audio, and other sensor analysis may be used to detect when a pause event or a resume event may be triggered. For triggered pause events, at least some of the video communication data may no longer be transmitted as part of the video communication. For triggered resume events, a pause state may cease and all of the video communication data may be transmitted.
