Method for transmitting real time multimedia datain ethernet network

A method for effectively implementing real time multimedia data transmission in an Ethernet network that operates in a CSMA / CD (Carrier Sense Multiple Access / Collision Detect) scheme. Real time data gets priority over general data, and uses an MPCP (Multi-Point Control Protocol) of the IEEE 802.3ah EPON to prevent a collision from occurring in real time data transmission, and also prevents delay time variation. An RT-IFG (Real Time Inter-Frame Gap) is defined for real time data, shorter than an IFG, to give priority to the real time data over general Ethernet data. The MPCP is used for transmission of real time data without collision between the real time data.

Dll circuit adapted to semiconductor device

A DLL circuit is designed to adjust the delay time and the duty applied to an input clock signal, thus producing a DLL clock signal. In a non-clocking state of the DLL clock signal in which pulses disappear temporarily, the DLL circuit stops updating the delay time and the duty of the DLL clock signal. That is, the DLL circuit is capable of preventing a phase difference between the input clock signal and the DLL clock signal from being erroneously detected in the non-clocking state of the DLL clock signal, thus preventing the delay time and the duty from being updated based on the erroneously detected phase difference. Thus, it is possible to reduce the number of cycles adapted to the delay-locked control and to thereby stabilize the operation of the DLL circuit.
