Method and system for multiplexing packets

A packet multiplexing system for receiving and multiplexing variable length packet streams including a plurality of packets having an initial packet and a final packet, through a plurality of lines, comprising:

• a buffer memory that stores the packets that are received through the plurality of lines;
• and
• a controller that controls writing and reading of the packets to and from the buffer memory for each of the packet streams, wherein said controller is configured to;
• write and store an identifier of one of the plurality of line lines and the packets that are received through that line, when the initial packet is received;
• select lines from the plurality of lines having corresponding initial packets, the number of said selected lines is not greater than a predetermined multiplexing number, out of the lines whose identifiers are stored;
• determine a multiplexing sequence of the packet streams that are received through the selected lines, and read the packets from the buffer memory according to the determined multiplexing sequence, wherein when the final packet of the packet stream, received through one of the selected lines is read from the buffer memory, the controller selects a new line having an initial packet for replacing the one of the selected lines that's final packet has been multiplexed and whose identifiers are stored,
• determine a new multiplexing sequence of the packet streams that are received through the selected lines, including the newly selected line;
• and
• read the packets from the buffer memory according to the newly determined multiplexing sequence.
