摘要： The present invention discloses a transmission device of a low-noise optical signal having a low-noise multi-wavelength light source, a transmission device of broadcast signals using a low-noise multi-wavelength light source, and an optical access network having the same.The present invention uses a low-noise multi-wavelength light source (LMLS) which has sufficiently low noises at respective wavelengths, while being lasing at a multi-wavelength. Noises at respective wavelengths are not increased, even though an output light of such an LMLS passes through a wavelength division multiplexer/demultiplexer (a tunable optical filter or an arrayed waveguide grating (AWG), etc.). When using an LMLS, it is possible to embody an optical access network capable of transmitting optical signals at a high-speed and simultaneously transmitting a multicast signal. Further, when embodying an optical amplifier by using a gain medium for an LMLS, it is possible to obtain gain at a broad band without cross-coupling.
摘要翻译：本发明公开了一种具有低噪声多波长光源的低噪声光信号的发送装置，使用低噪声多波长光源的广播信号的发送装置，以及具有该多个波长的光接收网络的光接入网。本发明使用在各波长处具有足够低噪声的低噪声多波长光源（LMLS），同时以多波长发射。即使这种LMLS的输出光通过波分多路复用器/解复用器（可调光滤波器或阵列波导光栅（AWG）等），各波长处的噪声也不会增加。当使用LMLS时，可以实现能够以高速传输光信号并且同时发送多播信号的光接入网络。此外，当通过使用用于LMLS的增益介质来实现光放大器时，可以在没有交叉耦合的情况下获得宽带的增益。

摘要： The present invention provides a stereoscopic image reproducing apparatus which provides a user interface (UI) appropriate for a 3D image signal, comprising: a user interface generating unit which generates the user interface; a UI-scaling unit which scales the generated UI in accordance with the mode of the 3D image signal; a first storage unit which stores the scaled UI together with a first position value; a second storage unit which copies the UI stored in the first storage unit, and stores the copied UI together with a second position value in accordance with the mode of the 3D image signal; and an integrated storage unit which integrates the UIs stored in the first storage unit and in the second storage unit in accordance with the position value of each of the UIs, and stores the integrated UIs. Preferably, the UI-scaling unit performs a downscaling process for reducing the generated UI in the horizontal direction when the 3D image signal has a side-by-side mode. In addition, the UI-scaling unit preferably performs a downscaling process for reducing the generated UI in the vertical direction when the 3D image signal has a top-down mode. The present invention thereby provides a user interface which causes no distortion in a stereoscopic image display.
