1. A method of transmitting data received from plural sources that are not synchronized with each other and a packet source as a single data stream comprising the steps of:
- synchronizing data received from the plural sources that are not synchronized with each other to thereby generate a synchronized data rate;
providing a frame format comprising a plurality of frames, each frame having plural sub-frames, the number of which correlates to the number of plural sources that are not synchronized with each other and each sub-frame comprising a plurality of blocks, each block comprising;
at least one overhead bit position,n bit positions of the synchronized data,m bit positions of data received from the packet source arranged as a function of the synchronized data rate, anda plurality of sub-blocks each having a bit position for the synchronized data or a bit position for data received from the packet source;
assigning the synchronized data and data received from the packet source in bit positions of the frame format; and
transmitting the assigned data as a single data stream.

Abstract
A method of efficiently combining data from at least a plurality of a first type of data source and a second type of data source. The method comprises synchronizing the plural first type of data sources to thereby generate a synchronized data rate, providing a frame having plural bit positions, assigning the synchronized first type of data in ones of the bit positions of the frame, and arranging the second type of data in the frame as a function of the synchronized data rate.

9. A system for transmitting data received from plural sources that are not synchronized with each other and a packet source as a single data stream, the system comprising:
-
means for synchronizing data received from the plural sources that are not synchronized with each other to thereby generate a synchronized data rate; and means for providing a frame format comprising a plurality of frames, each frame having plural sub-frames, the number of which correlates to the number of plural sources that are not synchronized with each other and each sub-frame comprising a plurality of blocks, each block comprising; at least one overhead bit position, n bit positions of the synchronized data, m bit positions of data received from the packet source arranged as a function of the synchronized data rate, and a plurality of sub-blocks each having a bit position for the synchronized data or a bit position for data received from the packet source; wherein the means for providing the frame format is further configured to assign the synchronized data and data received from the packet source in bit positions of the frame format; and wherein the means for providing the frame format is further configured to transmit the assigned data as a single data stream. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A system for transmitting data received from plural sources that are not synchronized with each other and a packet source as a single data stream, the system comprising:
-
synchronizers configured to receive data from the plural sources that are not synchronized with each other to thereby generate a synchronized data rate; and a multiplexer configured to provide a frame format comprising a plurality of frames, each frame having plural sub-frames, the number of which correlates to the number of plural sources that are not synchronized with each other and each sub-frame comprising a plurality of blocks, each block comprising; at least one overhead bit position, n bit positions of the synchronized data, m bit positions of data received from the packet source arranged as a function of the synchronized data rate, and a plurality of sub-blocks each having a bit position for the synchronized data or a bit position for data received from the packet source; wherein the multiplexer is further configured to assign the synchronized data and data received from the packet source in bit positions of the frame format; and wherein the multiplexer is further configured to transmit the assigned data as a single data stream. - View Dependent Claims (18, 19, 20, 21, 22)
