Systems, methods and computer program products, for identification of materials based on hyperspectral imagery, are disclosed. A first device, which is operatively coupled to a link-local network, generates a Multicast Domain Name System IP multicast query message, which it then sends to a second device on the link-local network. For each of the scales and associated subsets, a statistic on occurrences of content associated with the metadata in each subset is determined and the statistics are aggregated for each scale and associated subsets to determine a semantic level for the content. The reduction ratio used by the resolution converting section is encoded, and the transmitting section transmits this encoded reduction ratio along with encoded data on the binary picture. Therefore, the present invention can obtain an effect such as using a SOI substrate or a SIMOX substrate and can prevent a lowering in an electrical characteristic of the device, by using a bulk substrate made of a single crystal silicon but forming an insulating layer into which oxygen is injected below a LDD region.
