1. A method for selecting a codec, comprising:
- a terminal determining a codec list for a new packet-switched connection between terminals using a table in which a transmission capacity associated with a destination address range is indicated for at least one destination address, wherein the terminal selects the codec from the codec list, wherein the codec transmits at least one of audio and video data between at least two terminals through the new packet-switched connection;
the terminal measuring transmission capacities associated with the destination address range;
the terminal automatically updating the table by creating table entries based on the transmission capacity measurements, wherein the table entries include a confidence interval associated with a confidence in one of the transmission capacity measurements; and
the terminal providing the updated table for subsequent packet switched connections.

Abstract
The invention relates to a method for selecting a codec for transmission of audio and/or video data between terminals (1, 3) through a packet switching connection (2), the terminals (1, 3) selecting the codec from a codec list, characterized in that the codec list for a new connection is determined by means of a table in which for at least one destination address range, the associated transmission capacity is indicated and the table is automatically updated through measurements, as well as a terminal for carrying out the method.

15. A terminal, comprising:
-
a table data structure stored at the terminal in which, for at least one destination address range, an associated transmission capacity is indicated; a module operable to; determine, from the table, a codec list for a new packet-switched connection between the terminal and another terminal; measure transmission capacities for the new packet-switched connection between the terminal and the another terminal; automatically update the table by creating table entries based on the transmission capacity measurements, wherein the table entries include a confidence interval associated with a confidence in one of the transmission capacity measurements; and provide the updated table for subsequent packet switched connections. - View Dependent Claims (16, 17, 18, 19, 20)
