Videoconferencing

摘要

A method performed by a videoconferencing device, the method comprising: maintaining a database (129) comprising multiple records, each record including bit rate information and relating to a particular endpoint identifier; initiating a videoconference call with a target endpoint (101, 103); identifying (S2) one or more records in the database (129) that relate to the endpoint identifier of the target endpoint (101, 103); identifying (S5) one or more records in the database (129) that relate to the endpoint identifier of one or more endpoints located in a common zone with the target endpoint (101, 103); using bit rate information from the identified records to calculate (S4, S7, S8) an initial video bit rate for the videoconference call; and initially transmitting video to the target endpoint (101, 103) at the calculated initial video bit rate. Apparatus configured to implement the foregoing method.

1. A method performed by a videoconferencing device, the method comprising:
maintaining a database comprising multiple records, each record including bit rate information and relating to a particular endpoint identifier; initiating a videoconference call with a target endpoint; identifying one or more records in the database that relate to the endpoint identifier of the target endpoint; identifying one or more records in the database that relate to the endpoint identifier of one or more endpoints located in a common zone with the target endpoint; using bit rate information from the identified records to calculate an initial video bit rate for the videoconference call; determining as a first value, from each record relating to the endpoint identifier of the target endpoint, a weighted average of the average video bit rate, at which video was transmitted to the target endpoint, during previous videoconferencing sessions therewith; and initially transmitting video to the target endpoint at the calculated initial video bit rate.
