DISTRIBUTED MULTI-POINT CONFERENCE SYSTEM, METHOD THEREFOR, CHIP AND STORAGE MEDIUM
Document Type and Number:
Japanese Patent JP3363424
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the link capacity which is required to one or more attendant terminals by making an attendant terminal other than its own one receive directly the media streams from an optional terminal and a multi-point distributor other than its own one that joins in a distributed multi-point conference system.
SOLUTION: This system comprises the attendant terminals 31-33, and the terminal 31 is related with a multi-point distributor(MD) 30. The terminals 32 and 33 excluding the terminal 31 related to the MD 30 transmit directly the media streams 32', 32", 33' and 33" to other terminals. The terminal 31 is supported by the MD 30. In other words, the terminal 31 does not transmit (N-1) media streams and transmits only a single stream 31' to the MD 30. The MD 30 distributes again the stream 31' to the terminals 32 and 33 via the streams 30' and 30".
