Abstract
A video encoder (2) is disclosed for sending video data to a server (4) over a channel. A video compressor (16) can compress video data using an adjustable compression factor. A multiplexer/pack constructor (18) can receive compressed video from the compressor, together with non-video data, and can queue data for transmission. A bandwidth monitor (20) is provided for monitoring the performance of the channel based on the behaviour of transmitted data packets, including their round-trip travel time to and from the server (4). The compressor (16) can modify the adjustable compression factor based on the performance of the channel, as determined by the bandwidth monitor, and the amount of non-video data received by the packet constructor. This can permit transmission of non-video data without disrupting the live video feed or introducing any delay.
