    • Systems and methods of performing rate control in scalable video encoders that can be used to provide videoconferencing, announcements, and live video streaming to multiple participant devices having diverse bandwidths, resolutions, and/or other device characteristics. The systems and methods can accommodate different target bit rates of the multiple participant devices by operating on scalable video bitstreams in a multi-layer video format, including a base layer having one or more reference video frames, and an enhancement layer having one or more disposable non-reference, predictive video frames. By adjusting the number of disposable non-reference, predictive video frames in the enhancement layer, as well as quantization parameters for the respective base and enhancement layers, the disclosed systems and methods can accommodate the different target bit rates for the respective participant devices, while enhancing the spatial and/or temporal qualities of the base and enhancement layers in the respective video bitstreams.
    • 在可扩展视频编码器中执行速率控制的系统和方法,可用于向具有不同带宽,分辨率和/或其他设备特性的多个参与者设备提供视频会议,通告和实时视频流。 系统和方法可以通过以包括具有一个或多个参考视频帧的基本层的多层视频格式的可缩放视频比特流进行操作来适应多个参与者设备的不同目标比特率,以及具有一个或多个一次性 非参考,预测视频帧。 通过调整增强层中的一次性非参考预测视频帧的数量以及相应的基本和增强层的量化参数,所公开的系统和方法可以适应各个参与者设备的不同的目标比特率,而 增强相应视频比特流中的基本和增强层的空间和/或时间质量。

    • Systems and methods of handling packet errors associated with multimedia data received at data receivers from data senders, in which packet error feedback information is provided by the data receivers to the data senders in one or more real-time transport control protocol (RTCP) feedback packets. The data receivers can calculate, determine, or otherwise obtain costs associated with providing specific forms of packet error feedback information in the RTCP feedback packets, and further calculate, determine, or otherwise obtain wait times for handling out-of-order packets, as well as receiving retransmissions of lost packets. By handling packet errors associated with multimedia data while taking into account such costs and wait times, each of which can have an impact on system bandwidth and/or latency, the systems and methods can more reliably achieve the quality of experience (QoE) generally desired and/or required for multimedia data transmissions.
    • 处理与来自数据发送器的数据接收器处接收的多媒体数据相关联的分组错误的系统和方法,其中数据接收器向一个或多个实时传输控制协议(RTCP)反馈分组中的数据发送器提供分组错误反馈信息 。 数据接收器可以计算,确定或以其他方式获得与在RTCP反馈分组中提供特定形式的分组错误反馈信息相关的成本,并且进一步计算,确定或以其他方式获得处理无序分组的等待时间,以及 作为接收丢失数据包的重传。 通过处理与多媒体数据相关联的分组错误,同时考虑到这些成本和等待时间,其中每一个可能对系统带宽和/或延迟产生影响,系统和方法可以更可靠地实现通常期望的体验质量(QoE) 和/或多媒体数据传输所需的。
