A multimedia communication arrangement processes and multiplexes different types of data, including data from an adaptive data rate data source and a nonadaptive data rate data source, to substantially increase data throughput over a communication channel. The rate at which data is collected from the adaptive data rate data source varies based on the available channel bandwidth of the modem. The transmission rate is optionally adjusted in response to a detected error rate. Furthermore, the amount of filtering performed by a video camera on an image before the image is encoded by a codec can be adjusted. In addition, a data recovery terminal optionally selectively adjusts intervals at which received audio data is sampled to potentially reduce latency periods.
