Abstract
To conduct video conferencing between a plurality of distributed clients, a distributed controller receives a request from a first distributed client for a packet from a second distributed client selected as the main speaker, and a distributed media processor creates a switching entry for switching packets from the first and second distributed clients, in response to a request from the distributed controller. The distributed controller sends a packet transmission request to the second distributed client, and the distributed media processor receives a packet from the second distributed client and sends the received packet to the first distributed client based on the switching entry.
Claims19
A video conferencing method for a video conferencing apparatus, the method comprising:
- a distributed controller receiving a request from a first distributed client for a packet from a second distributed client selected as a main speaker;
- a distributed media processor creating a switching entry for switching packets from the first and second distributed clients, in response to a request from the distributed controller;
- the distributed controller sending a packet transmission request to the second distributed client;
- and
- the distributed media processor receiving a packet from the second distributed client and sending the received packet to the first distributed client based on the switching entry.
A video conferencing apparatus which conducts video conferencing between a plurality of distributed clients, the apparatus comprising:
- a plurality of distributed media processors that send or receive packets to and from the plurality of distributed clients and correspond to the plurality of distributed clients;
- and
- a distributed controller that requests the distributed media processors to create an identifier-based switching entry for packet transmission to the distributed media processors, upon receiving a conference participation request from the distributed clients or a request from the distributed clients for a packet from the distributed client who is a main speaker,
- wherein each of the distributed media processors creates a switching entry and transmits a packet received from the distributed clients to other distributed clients, based on the created switching entry.
A distributed client device, which conducts video conferencing via a network in connection with a video conferencing apparatus including a distributed controller and distributed media processors, the device comprising:
- a conference participation requestor that makes a request for participation in a conference while sending a video conference participation request message to the distributed controller;
- a first-resolution packet processor that sends or receives packets having a first resolution that is lower than a set resolution;
- a second-resolution packet processor that sends or receives packets having a second resolution that is higher than the set resolution;
- and
- a display section that divides the display screen into a first region and a second region, the first region displaying videos corresponding to first-resolution video packets, and the second region displaying videos corresponding to second-resolution video packets.
