Method and device for filtering media packets

Abstract

A method in a video conferencing device for filtering media packets from a video conferencing data stream. The video conferencing device includes a media processing network, a general purpose network, a soft core processor, a lookup table memory (LUT) and a full network stack. The method includes receiving a packet of a video conference media stream at the soft-core processor, determining whether the length of the packet is long enough to contain the media, determining whether the protocol of the packet is supported by the soft-core processor, finding the packet's a media stream ID, using the media stream ID as an input value to send a request to the LUT while concurrently determining whether the packet is a valid media packet; and when receiving a destination address in the media processing network from the LUT and When the packet is determined to be a valid media packet, modifying a header of the packet with the destination address received from the LUT; and routing the packet to the modified destination address. A video conferencing device is adapted to perform the method.

Description

technical field [0001] The present invention relates generally to the processing of videoconferencing data. More particularly, the present invention relates to a method of filtering media packets from a videoconferencing data stream, and a videoconferencing device, such as a multipoint control unit, that implements the method. Background technique [0002] Video conferencing and related hardware generally fall into two camps. In the first camp, a "conference" takes place between just two participants, and the participants are directly connected to each other through some form of data network. In this form of networking, only two endpoints are involved, and a real meeting only takes place if there are multiple participants at one of the two endpoint sites. Examples of such conferencing on the low-tech end are or Skype PC-enabled endpoints interconnected by software such as SNAP, and at the higher end are devices utilizing dedicated endpoint hardware interconnected eg vi...

Problems solved by technology

While this architecture is a great improvement over existing technologies because board-to-board communication is greatly reduced, board-to-board communication still relies on the processor to filter packets and redistribute media packets to the DSP with a full network stack

This places an unnecessary load on the processor, slowing down the system

despite the contact image 3 and 4 The architecture is specifically mentioned, but this is not relevant for the figure 2 The PCI bus-based MCU architecture shown in the even bigger problem
