CONSTITUTION: An SRS(Supplementary Reference Signal) insertion unit(340) inserts a supplementary signal into a transport stream. A RS(Reed-Solomon) encoder(350) performs RS encoding of the transport stream. An interleaver(360) interleaves the RS-encoded transport stream. A trellis encoder(370) performs trellis encoding of the interleaved transport stream. The trellis encoder is initialized before the trellis encoding of the supplementary signal is performed.

Abstract: A method for enhancing a color temperature of a color image is provided. Gains for input image signals are calculated based on a predetermined gain function. A first offset value corresponding to a change in a predetermined 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 the 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 output signals.

Abstract: PURPOSE: DVD information transmission device and a method for the same are provided to transmit DVD information without regard to a function and construction of a device receiving a transmitted data, by properly varying a transmission format in order to output DVD information. CONSTITUTION: A device for transmitting DVD(digital versatile disc) information to another device includes a stream format converter, a re-coding device, and a stream selector. The stream format converter converts audio information and video information having a stream format to a transmission stream format, and provides a first stream. The video and audio information is read from DVD. The re-coding device mixes a video information with a sub-picture information from DVD, re-codes the mixed information according to a compressed coding system of a predetermined video information, and provides a second stream. The stream selector selects a first stream or a second stream according to a bandwidth of a transmission channel and information processing capacity of the device. The stream selector transmits the selected one to another device. Thereby, DVD information transmission device transmits DVD information without regard to a function and construction of a device receiving a transmitted data.
