Method and Apparatus for Providing a Low Latency Transmission System Using Adjustable Buffers

摘要

One aspect of the present invention discloses a network system capable of transmitting and processing audio video (“A/V”) data with enhanced quality of service (“QoS”). The network system includes a transmitter, a transmission channel, an adjustable decoder buffer, and a decoder. The transmitter contains an encoder able to encode A/V data in accordance with encoding bit rate recommendation from SQoS and packets loss notifications. The transmission channel, in one example, transmits A/V data from the transmitter or the receiver. The adjustable decoder buffer, in one aspect, is able to change its storage capacity or buffering size in response to the adaptive latency estimate. Upon fetching at least a portion of the A/V data from the adjustable decoder buffer, SQoS updates the adaptive latency estimate based on the quality of the decoded A/V data.

1. A method for processing data from a network, comprising:
fetching a first data stream from a decoder buffer with a first buffer capacity; decoding the first data stream and identifying data integrity associated with the first data stream based on a set of predefined parameters; generating an adaptive latency estimate in response to the data integrity associated with the first data stream based on the first buffer capacity; adjusting the decoder buffer from the first buffer capacity to a second buffer capacity in accordance with the adaptive latency estimate; and receiving a second data stream from a communications network and storing the second data stream in the decoder buffer with the second buffer capacity.
