Jitter buffer

摘要

Methods, transmitter, receiver and computer program product for transmitting or receiving data of a real-time communication event, the data being transmitted from the transmitter to a jitter buffer of the receiver. At least one processing parameter describing how data is to be processed for transmission from the transmitter to the jitter buffer in the real-time communication event is determined at the transmitter. Data is processed for transmission from the transmitter to the jitter buffer in accordance with the determined at least one processing parameter. Control information based on the determined at least one processing parameter is transmitted from the transmitter to the receiver, wherein the control information is for use by the receiver to control a state of the jitter buffer. The processed data is transmitted from the transmitter to the jitter buffer of the receiver in the real-time communication event.

1. A computer-readable storage memory device comprising instructions executable by one or more processors to perform operations to transmit data of a real-time communication event from a transmitter to a jitter buffer of a receiver, the operations comprising:
determining at least one processing parameter describing how the data is to be processed for transmission from the transmitter to the jitter buffer in the real-time communication event; processing the data for transmission as a stream of data packets from the transmitter to the jitter buffer in accordance with the determined at least one processing parameter, the processing the data comprising generating correction data units relating to at least one of the data packets, the at least one processing parameter comprising a correction depth that sets a maximum allowable displacement in the stream of the data packets between an oldest and a newest of the data packets that are allowed to be related to one of the correction data units; transmitting, to the receiver, control information based on the determined at least one processing parameter, the control information being effective to enable the receiver to control a state of the jitter buffer; and transmitting the processed data to the jitter buffer of the receiver in the real-time communication event.
