A Video Conference Recorder (VCR) provided with integral input transcoders which convert received video call data into an intermediate format. Once the input transcoder has processed the data it passes it to a memory in the VCR where it is stored until a user requires it to be played back. If required the data can be converted into more than one output format using multiple input transcoders. On receiving a request to play back a recording the VCR locates the data in its memory and sends it to an output transcoder, integral to the VCR. If the stored data format is one that the endpoint can receive then the output transcoder transmits the data across the network to the endpoint. If, however, the endpoint cannot receive the stored data format then the output transcoder converts the data into a format which the endpoint can receive before onward transmission.
