The DMB standards allow to transmit IP data on IP Tunneling. It is able to DMB data localcasting services using technologies as assigning IP address, encapsulating IP packets, guiding IP data service and, exchanging IP packet at the local area. As the result of that, we can have good experiences as rich and localized multimedia on the DMB networks.

We have fabricated YBa$_2Cu_3O_{7-x}$ thin films by cylindrical hollow cathode sputtering. For 2 inch diameter of MgO (100) substrate, we obtained the zero resistance temperature in the range from 83 K to 86 K and thickness uniformity better than 5 % over the whole area. Also, the average deposition rate was 100nm/h which is higher than 10 times compare to conventional off-axis sputtering method. These results indicate that cylindrical hollow cathode sputtering seems to have unique capabilities for high rate and homogeneous deposition of large area thin film.

Active layer patterned OTFT was obtained on a plastic substrate using the optimal growth condition of pentancene thin films as active layer and parylene thin films as passivation layer. Tranditional photolithography was performed to use a dry etch to pattern the material stack. The pentacene thin film and parylene thin film were deposited onto a plastic substrate using PC-OVD and CVD, respectively.

The DRM+ is the newest digital radio standard for in-band environment. Although various state of the art technologies are adopted, the performance evaluation information is not sufficient. It is hard that many countries and stations considering the DRM+ as their digital radio standard check the performance of DRM+. To evaluate the performance of the DRM+ system, this paper depicts the laboratory trial results of DRM+ standard. In the laboratory trial, the rack type DRM+ test bed is built. To reflect the practical broadcasting environment, various tests are executed. Many countries and stations can efficiently use these test results, which are considering converting their analog radio broadcasting to digital broadcasting.

We propose a new method for the formation of an aluminum parting layer in the fabrication of field emitter arrays, in which we used a reflow property of aluminum at a lower temperature than the deformation point of glass. After the sputtered aluminum layer on the gate metal was etched for the formation of gate holes, we carried out a rapid thermal annealing process, by which the aluminum slightly diffused into the gate hole. This reflowed aluminum could be used as a parting layer and emitter arrays were easily fabricated using this method.
