A method for registering customer premises equipment to provide an Internet service to the customer premises equipment by a network management apparatus of an access network structure, wherein the network management apparatus and the customer premises equipment are connected through a bundle cable including a plurality of lines in the access network structure, the method includes: transmitting a registration signal toward a customer premises equipment; receiving registration response signals transmitted from the customer premises equipment through the plurality of lines; analyzing the registration response signals introduced from the plurality of lines and distinguishing a direct signal transmitted through a properly connected line and interference signal from the registration response signals; and establishing a link with the customer premises equipment connected to the properly connected line. The interference signal is introduced through adjacent line of the properly connected line among the plurality of lines.

Network management apparatus, customer premises equipment registration method therefor, and method for providing internet service to customer premises equipment

A method for configurating a transmission mode to provide an Internet service to a customer-premises equipment by an transmission mode configurating apparatus in an access network structure is provided. At least one network management equipment and at least one customer-premises equipment are connected through a bundle of cables including a plurality of transmission lines. The method includes determining the number of transmission lines connected to the customer-premises equipment; determining at least one of available transmission mode to provide depending on the number of transmission lines; if a plurality of available transmission modes are determined, calculating a transmission performance in each of the available transmission modes; and selecting the transmission mode with the highest performance among the plurality of the available transmission modes.

Disclosed is a method for performing transmission frequency control for a subscriber line of a customer premise device by a transmission control apparatus in an access network structure in which at least one network management device and a plurality of customer premise devices are connected through a bundle cable including a plurality of subscriber lines. The transmission control method includes: setting a partial frequency band in an entire service frequency band provided by the subscriber line as a transmission frequency band of the customer premise device; and varying the transmission frequency band in the entire service frequency band when a triggering event occurs, in which traffic of the customer premise device is transmitted and received in the transmission frequency band.

A system and method for converting color images divides a first image into first RGB values per pixel, determines which of the RGB colors in the first image has a greater specific gravity, converts the first RGB values into second RGB color values based on the color with the greater specific gravity, and forms a second image based on the second RGB values. The color value conversion involves allocating a first number of bits to represent the second RGB value corresponding to the color having the predetermined specific gravity and a second number of bits to represent the RGB values corresponding to remaining ones of the colors. The first and second numbers of bits are different and preferably the first number is greater than the second number. Through this system and method, an M-bit color image may be converted into an N-bit color image with greater color accuracy than other methods which have been proposed.
