Abstract: The structure for an optical device according to an embodiment comprises a protective layer formed from a photocurable siloxane resin composition, wherein the protective layer is capable of serving not only to protect or seal a light emitting element such as a mini-LED chip from external heat or moisture, but also to improve such optical characteristics as brightness and contrast ratio of light emitted from the light emitting element through the light diffusion.

Abstract: Provided is a method and system for setting a new channel when a DVB-H terminal sets a channel initially or changes the channel. The method includes a DVB-H server transmitting Program Specific Information (PSI)/Service Information (SI) and burst data of Audio/Video (A/V) streams corresponding to a plurality of service channels, a DVB-H terminal detecting a number of a plurality of elementary streams included in a new channel and Packet Identifiers (PIDs) corresponding to the respective elementary streams from the PSI/SI, which has been received from the DVB-H server and stored, in response to a setting request of the new channel from a user, and setting the detected PIDs as temporary receive PIDs, and if the DVB-H terminal detects burst data having a PID equal to any of the temporary receive PIDs from among the burst data received from the DVB-H server, the DVB-H terminal sets the PID corresponding to the detected burst data as a final receive PID and received only burst data having the final receive PID.

Abstract: Disclosed is method of adaptive transmission in an OFDM system with multiple antennas. The adaptive transmission scheme includes an STBC, BLAST, and combined STBC/BLAST. By estimating channel environment, the method selects the proper transmission scheme among the STBC, BLAST, and STBC-BLAST. Therefore, the method has an advantage of each technique, e.g. diversity gain or high transmission rate. By using the method, the reliable and high data-rate communications are achieved.
