Relay including a mass memory for temporarily storing differed-time information streams

A method comprising:

• receiving an information stream including information cells, wherein some of said information cells are empty information cells;
• detecting said empty information cells in said information stream;
• determining whether said information stream includes real-time information or differed-time information;
• storing the differed-time information as differed-time information cells in a mass memory;
• selecting waiting cells from among the stored differed-time information cells;
• and
• replacing said empty information cells with said waiting cells for transmission.

A relay comprising:

• a first receiver adapted to receive a real-time information stream and a differed- time information stream;
• a stream analyzer for identifying the real-time information stream and the differed-time information stream;
• a memory for storing the differed-time information stream as differed-time cells;
• and
• a mixer adapted to provide an information stream for transmission to a second receiver, the information stream including the real-time information stream and at least a portion of the differed-time information cells, the mixer to insert the differed-time information cells along with the real-time information stream where the real-time information stream is at less than bandwidth capacity.
