Subscriber network receiving digital packets and transmitting digital packets below a predetermined maximum bit rate

A method of providing a transport stream, which includes a group of PID streams, wherein a PID stream is a stream of packets having a common packet identifier (PID) associated therewith, with a predetermined maximum bit rate, the method is implemented in a receiver-transmitter adapted to receive and transmit transport streams, the method comprising:

• receiving an input transport stream having a plurality of PID streams included therein, wherein packets in each of the PID streams have a respective PID value;
• determining at the receiver-transmitter whether to decrypt a first at least one PID stream of the plurality of received PID streams based on the PID value of the first at least one PID stream and an encrypt/decrypt look-up table;
• decrypting at the receiver-transmitter the first at least one PID stream based on the determination of whether to decrypt;
• statistically multiplexing at the receiver-transmitter a second at least one PID stream of the plurality of received PID streams into a group of PID streams, wherein the bit rate of the group of PID streams does not exceed the predetermined maximum bit rate;
• encrypting a third at least one PID stream of the plurality of received PID streams;
• transmitting from the receiver-transmitter a fourth at least one PID stream of the plurality of received PID streams from at least one transmitter;
• determining at the receiver-transmitter whether to statistically multiplex the second at least one PID stream;
