Jitter buffer

A transmitter for transmitting data of a real-time communication event to a jitter buffer of a receiver, the transmitter comprising a processor configured to:

• determine 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;
• process 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, including generation of correction data units relating to at least one of the data packets, the at least one processing parameter comprising a correction depth that sets the 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;
• transmit 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
• transmit the processed data to the jitter buffer of the receiver in the real-time communication event.

The computer-readable storage memory device comprising instructions executable by one or more processors to perform operations to receive, at a jitter buffer of a receiver from a transmitter, data of a real-time communication event, the operations comprising:

• receiving, from the transmitter, control information based on at least one processing parameter, the at least one processing parameter being used at the transmitter to process the data as a stream of data packets, including 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;
• controlling a state of the jitter buffer based on the received control information;
• and
• receiving the data of the real-time communication event, from the transmitter, at the jitter buffer of the receiver.
