摘要:
The present invention is a method of correcting packet discontinuities using the steps of: (A) generating a continuous real time data stream from input of media content from a media source comprising packets transmitted by way of a computer packet network to a specific receiving device to establish a transmission portion of an end to end communication, (B) a jitter buffer receiving real time data stream packets from the packet network and temporarily storing at least some of them in the jitter buffer, (C) the jitter buffer operating on multiple fixed length packets to output a first output of a predetermined sequence of said fixed length packets, preferably substantially as they were originally transmitted, (D) a control unit receiving the first output and changing the length of one or more of fixed length packets of the first output to form a second output in response to a detected delay or other discontinuity in the packet sequence, (E) a playout buffer receiving the second output and operating on the stream of original and varied length packets to deliver them to a digital to analog converter (DAC), and (F) transmission of analog output of the DAC to interface devices such as displays, speakers, and mechanical devices for intelligible playout of the media content for appreciation by a human interacting with the interface devices.
