Abstract: Technologies are described for performing equation-based rate control using delay. For example, an observed network data rate and a network delay can be obtained for a network communication. A target network data rate can be calculated using the observed network data rate and the network delay. The target network data rate is calculated using an equation-based approach. For example, the equation-based rate control can set the target network data rate to a value that is directly proportional to the observed network data rate and inversely related to the network delay. The target network data rate is used to set the bitrate for the network communication.

Abstract: A computing system manages communications congestion by selecting a transmission rate differently in different operating modes. In a delay-plus-loss mode, the transmission rate is selected as the lesser of a rate that would be selected by loss-based algorithm or by a delay-based algorithm. In a loss-based mode, the transmission rate is selected as the lesser of a rate that would be selected by loss-based algorithm, on one hand, and the maximum of a rate that would be selected by a delay-based algorithm or a rate proportional to the maximum estimated link rate divided by the number of data flows estimated to be competing for link bandwidth on the other hand. A database may be maintained of observations of network and link performance over time, where the database contains such information as the maximum estimated link rate capacity, minimum delays, and minimum losses.

Abstract: An audio decoder provides a combination of decoding components including components implementing base band decoding, spectral peak decoding, frequency extension decoding and channel extension decoding techniques. The audio decoder decodes a compressed bitstream structured by a bitstream syntax scheme to permit the various decoding components to extract the appropriate parameters for their respective decoding technique.
