The present invention provides a light-emitting device with a reflection layer and the structure of the reflection layer. In one implementation, the invention can be characterized as a capacitor based pulse forming network comprising a plurality of inductors adapted to be coupled to a load, a plurality of capacitor units, and a plurality of switches. Time slots are generated in such a manner that when the chroma format detected from the header is 4:2:2, in all periods of DCT blocks, a process is performed and that when the chroma format detected from the header is 4:2:0, a process is not performed in periods for DCT blocks Cb2 and Cr2 that are not present in the chroma format 4:2:2.
