Reducing delay in video telephony |
摘要 |
In an example, a method of processing data includes transmitting data over a network at a first bit rate, identifying a reduction in a network link rate of the network from a first network link rate to a second network link rate, and in response to identifying the reduction in the network link rate, determining a recovery bit rate at which to transmit the data over the network, where the recovery bit rate is less than the second network link rate. The method also includes determining a buffering duration based on a difference between a time of the identification of the reduction in the network link rate and an estimated actual time of the reduction in the network link rate, and determining a recovery rate duration during which to transmit the data at the recovery bit rate based on the recovery bit rate and the buffering duration. |

1. A method of processing data, the method comprising:
transmitting data over a network at a first bit rate; identifying a reduction in a network link rate of the network from a first network link rate to a second network link rate; in response to identifying the reduction in the network link rate, determining a recovery bit rate at which to transmit the data over the network, wherein the recovery bit rate is less than the second network link rate; determining a buffering duration based on a difference between a time of the identification of the reduction in the network link rate and an estimated actual time of the reduction in the network link rate; and determining a recovery rate duration during which to transmit the data at the recovery bit rate based on the recovery bit rate and the buffering duration. |
