Abstract
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.
