    摘要： An improved electro-optical system has a planar waveguide coupled to a photodetector through a transparent substrate. The planar waveguide is within a planar optical structure that can be part of optical communication network. The photodetector is positioned to receive light that passes from the waveguide through the transparent substrate. The photodetector can be electrically coupled to electrical circuitry along the transparent substrate for connection to a electrical apparatus. Corresponding methods for forming the electro-optical structure are described. These improved electro-optical systems can be used for terminating an optical transmission system at an end user or a local network associated with a group of end users.

    摘要： A multichannel audio format provides a truly discrete as well as a backward compatible mix for surround-sound, front or other discrete audio channels in cinema, home theater, or music environments. The additional discrete audio signals are mixed with the existing discrete audio channels into a predetermined format such as the 5.1 audio format. In addition these additional discrete audio channels are encoded and appended to the predetermined format as extension bits in the bitstream. The existing base of multichannel decoders can be used in combination with a mix decoder to reproduce truly discrete N.1 multichannel audio.
