Abstract: PROBLEM TO BE SOLVED: To reduce the complicatedness of a hardware and to perform variable speed services to many clients by using the integer number of (z) point IDFT modulator modules of one type and utilizing discrete multiple tone codes. SOLUTION: The clients(CLs) 1-W are provided with an encoder 6 and an IDFT modulator (IDFT) 8 and the IDFT 8 uses (z) point IDFTs which are basic IDFT modules for plural pieces depending on the number of sub channels (SCs) required by the CLs 1-W. For instance, in the case of requiring two audio channels, the CL 1 is allocated with the two SCs and provided with the two (z) point IDFTs. The encoder 6 maps signals from the CL1 to composite sub symbols, that are the discrete multiple tone codes, and outputs them to the (z) point IDFT. Thus, the complicatedness of the IDFT 8 is reduced and the communication speed of the CLs 1-W is made variable for the respective plural- folds of the SC.

Abstract: A system, method and apparatus for Video-on-demand (VOD) satisfying the desire of 'surfers'. The process entails a server operating in a standard Near-Video-on-demand (NVOD) mode, whereby it repeatedly transmits multiple copies of each program on separate channels. Each copy is delayed by a stagg eredtime interval. The server also repeatedly transmits a beginning portion of each NVOD program of a duration up to the staggered time interval. The invention provides a way to fulfill a VOD user requests asynchronous with the start of a NVOD transmission but which still makes primary use of the NVOD transmission for thatrequestor. The invention further advantageously prov ides fixed asset utilization in a predictable manner.

Abstract: A system and method for Video-on-Demand (VOD) satisfying the desire of 'surfers'. The process entails a server operating in a standard NVOD mode, w hereby it continuously sends multiple copies of each program on separate channels. Eachcopy is delayed by a staggered time interval. The in vention provides a way to fulfill a VOD user request asynchronous with the start of a NVOD transmission but wh ich still makes primary use of the NVOD transmission for that requestor. The sys tem and method combines independent server service satisfying an asynchronous reques t for only a short duration, usually less than or equal to the NVOD staggered time interval, and then aligns that requestor with an immediately previously commenced NVOD transmission.
