Abstract
Provided is a method for reconstructing non-continuous packetized data of a continuous data stream from a data connection into a reconstructed continuous data stream at the receiving point of a packet-based network, the method including gathering measurements of the data connection; predicting at least one value characterizing the data connection based on the gathered measurements using an estimation method; evaluating a de-jittering delay for the data connection based upon the at least one value characterizing the data connection; and delaying and converting the data packets based on the evaluated de-jittering delay.

A method for reconstructing non-continuous packetized data of a continuous data stream from a data connection into a reconstructed continuous data stream at a receiving point of a packet-based network, comprising:
- gathering measurements of the data connection,
- predicting at least one value characterizing the data connection based on the gathered measurements using an estimation method,
- evaluating a de-jittering delay for the data connection based on the at least one value characterizing the data connection, and
- delaying and converting data packets of the packetized data based on the evaluated de-jittering delay,
- wherein the estimation method comprises approximating a delay of a first arriving data packet of the packetized data as a pre-calculated mean delay value.
An output unit for reconstructing non-continuous packetized data of a continuous data stream into a reconstructed continuous data stream, the output unit comprising:
- means for gathering measurements of the data connection,
- means for predicting at least one value characterizing the data connection based on the gathered measurements using an estimation method,
- means for evaluating a de-jittering delay for the data connection based on the at least one value characterizing the data connection, and
- means for delaying and converting data packets of the packetized data based on the evaluated de-jittering delay,
- wherein the estimation method comprises approximating a delay of a first arriving data packet of the packetized data as a pre-calculated mean delay value.
A terminal with output unit for reconstructing non-continuous packetized data of a continuous data stream into a reconstructed continuous packet data stream, the terminal comprising:
- means for gathering measurements of the data connection,
- means for predicting at least one value characterizing the data connection based on the gathered measurements using an estimation method,
- means for evaluating a de-jittering delay for the data connection based on the at least one value characterizing the data connection, and
- means for delaying and converting data packets of the packetized data based on the evaluated de-jittering delay,
- wherein the estimation method comprises approximating a delay of a first arriving data packet of the packetized data as a pre-calculated mean delay value.
