  • Method for reliable detection of the status of an RTP packet stream
    Patent number: 8369310
    Abstract: In a method for determining the status of a real-time transfer protocol (RTP) packet stream, several steps are performed. A time period elapsed since reception of the last RTP packet is determined, the content of the last received RTP packet is determined, and the status of the RTP packet stream based on the elapsed time period and the content of the last received RTP packet is categorized. The method is advantageous in that the risk of false detection of dead RTP packet streams is reduced.
