Serial data are transmitted between transceivers via a communication path, each bit expressed by a dominant code or a recessive code which vary between dominant and recessive levels, the dominant code having a greater proportion of duration at the dominant level. The initiator may assist in the distribution and order the SCSI commands. The method is driven by a request for media content from a client, in response to which the server provides portions of the media content and monitors the reception rate of the content as it is sent to the client. The characteristics of temporal redundancies in video sequences are used in detecting objects in video sequences. The sending switch also includes code for setting a probability factor that is correlated to the capacity level where the probability factor increases as the capacity level increases and decreases as the capacity level decreases. The invention therefore has the advantage of allowing a much closer match of the sampling rate to the variable information density of the signal, thereby maximizing the sampling efficiency.
