Abstract: 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.

Abstract: The present invention provides a method of decoding two-channel matrix encoded audio to reconstruct multichannel audio that more closely approximates a discrete surround-sound presentation. This is accomplished by subband filtering the two-channel matrix encoded audio, mapping each of the subband signals into an expanded sound field to produce multichannel subband signals, and synthesizing those subband signals to reconstruct multichannel audio. By steering the subbands separately about an expanded sound field, various sounds can be simultaneously positioned about the sound field at different points allowing for more accurate placement and more distinct definition of each sound element.

Abstract: Various embodiments of the present invention provide deck protection systems for use with a deck structure, including planks and support structures. One embodiment provides a body having a deep end, shallow end, a trough section, and opposing side edges. The opposing side edges support the deck protection system between two parallel support structures, and water falling between the planks is captured by the trough and flows from the shallow region to the deep region to an exit located in the deep region. The water passes through the exit and a spout, preventing water from touching the supporting structures and preventing water from falling directly below the deck.
