Abstract: An Ethernet-based transmission system using a dying gasp according to the present invention includes an SMPS for supplying power to an Ethernet-based lower level system, detecting a state of a power fault, and outputting a dying gasp alarm signal. A CPU receives the dying gasp alarm signal, and generates and transmits an alarm packet. A PHY chip receives the alarm packet, and uplinks the alarm packet so that the alarm packet is transferred to a higher level stage. An L3 switch receives the alarm packet and determines whether a power fault has occurred in the lower level system. Accordingly, the present invention applies a dying gasp to an Ethernet-based or EPON-based transmission system and is then capable of generating and transmitting an alarm packet so that when a power fault occurs, a device in a higher level network can rapidly determine the occurrence of the power fault.

Abstract: A method of enhancing a color temperature of a color image includes calculating gains for input image signals based on a predetermined gain function. A first offset value corresponding to a change in a pedetermined color temperature of output signals is calculated. A second offset value is calculated based on the gains and the first offset value. The second offset value is added to a B signal of the output signals. A compensation gain is calculated in consideration of intensity of the B signal to which the second offset value is added. The compensation gain is added to a G signal. Thus, a desired color temperature can be obtained regardless of the intensities of R, G, and B signals.

This apparatus includes a stream format converter for providing a first stream by converting the program stream format of audio and video information read from the DVD into a transport stream format. A re-encoder is included, for providing a second stream by overlaying video information read from the disc with subpicture information read from the DVD and re-encoding the overlaid information using a predetermined compression encoding scheme for image information. A stream selector is included, for selecting either the first or second stream according to the requirements of a user, the bandwidth of a transmission channel, and the information processing capability of an apparatus for receiving information, and transferring a selected stream to the apparatus for receiving information via a transmission channel. Accordingly, information obtained using a selected optimal transfer method, that is, MPEG-2 full re-encoding, MPEG-2 I picture re-encoding, DV format re-encoding, or conversion of information stored in an original DVD into an MPEG-2 TS packet, is transferred. Therefore, even if DVD information is transferred to any apparatus, it can be viewed.
