Abstract:
In general, techniques are described for image generation for a collaborative sound system. A headend device comprising a processor may perform these techniques. The processor may be configured to determine a location of a mobile device participating in a collaborative surround sound system as a speaker of a plurality of speakers of the collaborative surround sound system. The processor may further be configured to generate an image that depicts the location of the mobile device that is participating in the collaborative surround sound system relative to the plurality of other speakers of the collaborative surround sound system.
Abstract:
In general, techniques are described for forming a collaborative sound system. A headend device comprising one or more processors may perform the techniques. The processors may be configured to identify mobile devices that each includes a speaker and that are available to participate in a collaborative surround sound system. The processors may configure the collaborative surround sound system to utilize the speaker of each of the mobile devices as one or more virtual speakers of this system and then render audio signals from an audio source such that when the audio signals are played by the speakers of the mobile devices the audio playback of the audio signals appears to originate from the one or more virtual speakers of the collaborative surround sound system. The processors may then transmit the processed audio signals rendered to the mobile device participating in the collaborative surround sound system.
Abstract:
A data transmitting apparatus is disclosed. The data transmitting apparatus includes a block generator which generates an Extended Display Identification Data (EDID) block regarding multi-channel audio data; and a transmitter which transmits the EDID block to a data receiving apparatus, wherein the EDID block includes at least one of a first sub block representing 3D audio characteristics of the multi-channel audio data, a second sub block representing 3D speaker placement information of the multi-channel audio data, and a third sub block representing multi-stream audio characteristics of the multi-channel audio data.
Abstract:
Die vorliegende Erfindung betrifft Vorrichtungen und Verfahren, um stereophone oder pseudostereophone Signale zu erzeugen. Insbesondere werden die Wechselbeziehungen von räumlichen und technischen Parametern untersucht und neue Wege für deren Optimierung vorgeschlagen. Ausserdem werden inverse Probleme in unerwarteter Weise auf Optimierungsprobleme der Umwandlung angewandt. Die Erfindung ist insbesondere für die Kodierung von Audiosignalen von Bedeutung.
Abstract:
Method and apparatus reproduce a stereophonic sound. The method includes obtaining sound depth information which denotes a distance between at least one object within a sound signal and a reference position, and providing sound perspective to the sound object output from a speaker, based on the sound depth information.
Abstract:
The electronic audio connection system of the present invention provides an experience much like sharing a room with several involved parties, even though the parties are physically separated. Speech enhancement and speech emphasis processing functions ensure parties perceive the speech captured in the audio signals, typically the most important portion of the captured audio signals. To capture audio signals, each space is provided a plurality of microphones (112) arranged in that space so that the sum audio signal captured by the microphones enables the creation of a sharable audio space. Each separate physical space transmits (116) its captured audio signals to a central server (104) via a bi-directional data communications medium. The central server (104) processes the summed audio signals and in turn transmits playable audio signals to each separate physical space. Speakers (110) located in each separate physical space aurally transmit the playable audio signals. This creates an audio space shared by each of the active separate physical spaces.
