Method and system for a transport single key change point for all package identifier channels

A method for processing data in a communication system, the method comprising:

• performing by one or more processors, one or more circuits, or any combination thereof:
• descrambling a received signal comprising multiple data channels with a plurality of key change points;
• synchronizing at least a portion of said plurality of key change points to occur at a common time instant by modifying one or more received scrambling control bits for said received signal, wherein the one or more received scrambling control bits specify a key parity;
• and
• re-scrambling at least one data channel in said descrambled received transport stream according to said synchronized key change points utilizing said one or more received scrambling control bits.

A non-transitory machine-readable storage medium having stored thereon, a computer program having at least one code section for processing data in a communication system, the at least one code section being executable by a machine for causing the machine to perform:

• descrambling a received transport stream comprising multiple package identifier (PID) channels with a plurality of key change points;
• synchronizing at least a portion of said plurality of key change points for each PID channel to occur at a common time instant by modifying one or more received scrambling control bits for said descrambled received transport stream, wherein the one or more received scrambling control bits specify a key parity;
• and
• re-scrambling at least one PID channel in said descrambled received transport stream according to said synchronized key change points utilizing said one or more received scrambling control bits.
