Abstract:
1. A method of initiating the bypassing of a pair of transcoding operations performed in series by a first transcoder arranged together with a first communication terminal on a local side of a communication network and by a second transcoder arranged together with a second communication terminal on a distant side of the communication network, said method comprising the steps of: receiving by the first transcoder arranged with the first communication terminal on a local side of a communication network from the second transcoder arranged with the second communication terminal on the distant side, in a first initial request to bypass transcoding operations, information about an encoding format currently in use by the second communication terminal on the distant side and about encoding capabilities of the second communication terminal, including the version of the bypassing protocol supported by the second transcoder; and, transmitting by the first transcoder arranged with the first communication terminal to the second transcoder arranged with the second communication terminal on the distant side, in a second initial request to bypass transcoding operations, information about an encoding format currently in use by the first communication terminal on the local side and about encoding capabilities of the first communication terminal, the information about the encoding capabilities including the version of a bypassing protocol supported by the first transcoder, to enable on one or on both sides a change of an encoding format currently in use prior to initiating the bypassing of the transcoding operations.
