[Problem] To enhance the ease of use of a network by a DLNA-compliant device. [Solving Means] A television receiverdiscovers another DLNA-compliant device connected to a network (S). Then the television receiverdetermines an IP address of eHDMI connection (S) and, in the case of a device directly connected by HDMI, connection setting of a DLNA with that device is automatically executed (Sthrough S). The television receivermay present each connection setting state to a user on a user interface screen, thereby making the user execute checking. In configuring an AV system, the user may execute direct connection by HDMI to enhance the ease of use of an AV systemwithout having to execute the connection setting of DLNA.

DLNA-compliant device, DLNA connection setting method, and program

An optical resonator includes a waveguide () formed by using an incidence side reflection film () and an emission side reflection film () arranged in parallel with each other and adapted to resonate light entering it by way of the incidence side reflection film () and adapted to propagate light formed and resonated so as to run through from the incidence side reflection () to the emission side reflection film (), a substrate () for forming the optical waveguide () on the top surface thereof and a first protection member () and a second protection member () corresponding to the material of the substrate () provided at an upper part of the waveguide () so as to make at least an end facet of each of the members form a plane () or () identical with the first end facet () or the second end facet (), whichever appropriate, of the substrate () including the light incidence end or the light emission end, whichever appropriate, of the optical waveguide () and the incidence side reflection film () and the emission side reflection film () are laid respectively on the formed planes (), ().

A resonance system () is formed by a light incident side reflection mirror and a light exiting side reflecting mirror, arranged parallel to each other. The light incident on an incident side reflective mirror () is propagated in the outward path direction or in the backward path direction so that the light is set in a resonant state. The light in the resonant state in the resonance system () is phase-modulated, responsive to a modulating signal supplied from an oscillating device () by a light modulation device () arranged between the light incident side reflective mirror () and the light exiting side reflective mirror (). The oscillating device oscillates the modulating signal of a frequency f. A plural number of sidebands, centered about the frequency of the incident light, are generated with an interval between neighboring sidebands equal to the frequency of the modulating signal, such as to modulate the phase of the light in the outward path direction and the phase of the light in the backward path direction.

An antenna apparatus has a first wire-like antenna element formed into a rectangular planar loop and a second antenna element which comprises two L-shaped plates electrically connected to the loop and mounted to a rectangular planar base member. The loop is hinged to the planar base member along long sides of the respective rectangles so that the angle between the planes of the loop and base member is adjustable. The base member pivots about an axis on a mount which can be secured to a television receiver.
