Video conferencing over IP networks
First Claim
1. A method comprising:
- establishing, by at least one processor of a first computing device, a first communication link over a packet network between a client component of the first computing device and a video communications server;
receiving, by the at least one processor and from the video communications server, instructions for initiating a video teleconference between the first computing device and a second computing device;
establishing, by the at least one processor, a second communication link over the packet network between a server component of the first computing device and the second computing device based on the received instructions;
transmitting, by the at least one processor and during the video teleconference, audio and video packets via the second communication link, wherein the audio and video packets respectively comprise audio and video data; and
transmitting, by the at least one processor and during the video teleconference, synchronization packets via the second communication link, wherein the audio and video packets are synchronized for output of the audio and video data at the second computing device based on synchronization information comprised in the synchronization packets.

Abstract
A method for communication includes establishing multiple communication links over a packet network between a server and plurality of client computers that are to participate in a video teleconference. The client computers may also create secondary communication links that function similarly to links between the server and client computers. The server receives from the client computers uplink audio packets and uplink video packets, which respectively contain audio and video data captured by each of the client computers. The server determines the optimal bandwidth for each client computer. The server also mixes the audio data from the uplink audio packets so as to create respective streams of mixed audio data for transmission to the client computers and transmits to the client computers downlink audio packets containing the respective streams of mixed audio data. The server relays the video data to the client computers in downlink video packets. The client computers receive and synchronize the video data with the mixed audio data.
