Program clock reference synchronization in multimedia networks

When a distributed media information in the through the information transmission method of program synchronous clock. Transmitter (110) processor (117) for calculating clock (CFsend difference) and difference between the clock module (CFw1) consisting samplings the direct-current samplings, a computational transmitted to a receiver scale-up factor K2=Diff_CFsend/Diff_CFw2. Receiver (130) processor (317) computer and a transmitter (110) are value; and program for clock (CFreceive) and clock system for maintaining contacts (CFw2) and K2=Diff_CFreceive/Diff_CFw2. The processor (137) compares K1 and K2 and generating for adjusting program receiver clock's band signal Δ K=K1-K2.
