Abstract: Virtual entities are displayed alongside real world entities in a wearable reality overlay device worn by the user. Information related to an environment proximate to the wearable device is determined. For example, a position of the wearable device may be determined, a camera may capture an image of the environment, etc. Virtual entity image information representative of an entity desired to be virtually displayed is processed based on the determined information. An image of the entity is generated based on the processed image information as a non-transparent region of a lens of the wearable device, enabling the entity to appear to be present in the environment to the user. The image of the entity may conceal a real world entity that would otherwise be visible to the user through the wearable device. Other real world entities may be visible to the user through the wearable device.

Abstract: An system, method, and method of encoding/decoding a multi-channel audio signal, including a decoding level generation unit producing decoding-level information that helps a bitstream including a number of audio channel signals and space information to be decoded into a number of audio channel signals, wherein the space information includes information about magnitude differences and/or similarities between channels, and an audio decoder decoding the bitstream according to the decoding-level information. Accordingly, even a single input bitstream can be decoded into a suitable number of channels depending on the type of a speaker configuration used. Scalable channel decoding can be achieved by partially decoding an input bitstream. In the scalable channel decoding, a decoder may set decoding levels and outputs audio channel signals according to the decoding levels, thereby reducing decoding complexity.
