Apparatus and method for simulcast over a variable bandwidth channel

An apparatus comprising:

• a scheduler including a transmission monitor operative to output a schedule periodically for a transmission of a plurality of multimedia contents to a client receiver over a unidirectional data communication channel,
• said schedule including a metadata indicating a plurality of broadcast times for respective ones of said plurality of multimedia contents;
• and
• a server coupled to said scheduler operative to transmit said schedule to a client receiver over said communication channel before a transmission of said plurality of multimedia contents for selectively activating said client receiver in accordance with said plurality of broadcast times,
• said transmission monitor operative to control said server for a transmission of said plurality of multimedia contents to said client receiver over said communication channel in accordance with said schedule,
• said transmission monitor operative to compare first and second available bandwidths of said communication channel at respective ones of first and second points in time,
• said scheduler operative to select one multimedia content file of a given compression level for transmission in response to a change of available bandwidth of said communication channel between said first and second points in time so that said plurality of multimedia contents may be received at said client receiver in accordance with respective ones of said plurality of broadcast times,
• said server operative to transmit said selected multimedia content file to said client receiver, wherein said transmission of said selected multimedia content file is a re-transmission of a previously-transmitted content at a different compression level.
