Abstract
A slot assignment technique for assigning slots to a video communiction source in a slotted communication channel entails, in embodiments, using a slot from the channel to issue a coded request message containing a bit pattern indicative of a number of other slots that the video communication source requires for transmitting video information. At the receiver, the number of slots that the video communication source requires for transmitting video information is identified from the coded request via a lookup table. The requiste number of slots in the communication channel can then be allocated to the video commuinication source to transmit the video information. The bit pattern indicative of the number of slots that the video communication source requires generally comprises less data than would an uncoded request for the same number of slots. In this way, request limitations imposed by request slot size may be overcome.
