Abstract: In certain embodiments, the system of the invention automatically replicates a user's personal computing environment and provides associated remote server access using authentication credentials and data files supplied by a local handheld device as coordinated by session level software common to the handheld device, the replicated system, the system on which the replication occurs, and the remote servers. The application enables a handheld computing device to transfer a user's various online account credentials to a user's other computing devices securely and automatically. Thereafter the other computing device accesses a user's cloud-based storage and various on-line accounts and also pulls selected documents, bookmarks and related information directly from a user's handheld.

Abstract: A data compressor has a delta value calculator which receives data items and determines if a related data item to a received data item is stored in a data store. If the related item is stored, the delta value calculator retrieves the related data item from the data store and calculates a delta value from the received data item and the related data item. If the related item is not stored, then the delta value is calculated from the received data item and a predetermined value. A data store controller accesses the data store in response to receipt of a data item and determines if a storage location is allocated to the data item. If there is an allocated storage location for the data item, the data item is stored in the allocated storage location; and if not then a storage location is allocated to the data item.

Abstract: Multi-channel audio signals are coded into a monaural audio signal and information allowing to recover the multi-channel audio signal from the monaural audio signal and the information. The information is generated by determining a first portion of the information for a first frequency region of the multi-channel audio signal, and by determining a second portion of the information for a second frequency region of the multi-channel audio signal. The second frequency region is a portion of the first frequency region and thus is a sub-range of the first frequency region. The information is multi-layered enabling a scaling of the decoding quality versus bit rate.

Abstract: Methods and apparatuses for encoding and decoding a multi-channel audio signal are provided. In the encoding method, spatial information is calculated based on a multi-channel audio signal and a down-mix signal, and a compensation parameter that compensates for the down-mix signal is calculated based on the multi-channel audio signal and the down-mix signal. Thereafter, a bitstream is generated by encoding the spatial information, the compensation parameter, and the down-mix signal and combining the results of the encoding. Therefore, it is possible to prevent deterioration of the quality of sound regarding a multi-channel audio signal by compensating for the multi-channel audio signal using a compensation parameter that compensates for a down-mix signal.

Abstract: In one embodiment, the method includes receiving the audio signal having a plurality of random access units. The random access unit includes one or more frames and at least one of the frames is a random access frame. The random access frame is a frame encoded such that previous frames are not necessary to decode the random access frame. The embodiment further includes reading location information from the audio signal. The location information indicates whether random access unit size information is stored or not in the audio signal. If the random access unit size information is stored, the location information further indicates a location where the random access unit size information is stored in the audio signal. Random access unit size information is read according to the location information. The random access unit size information indicates a distance between random access frames in bytes. The random access units are decoded based on the random access size information.

Abstract: In one embodiment, the method includes reading random access information from the audio signal. The random access information indicates whether or not random access operation is allowed in the audio signal. If the random access operation is allowed, the audio signal has a plurality of random access units. A random access unit includes one or more of frames and at least one of the frames is a random access frame. The random access frame is a frame encoded such that previous frames are not necessary to decode the random access frame, and the random access information further indicates a distance between random access frames in frames. The random access frame is decoded based on the random access information.

Abstract: A method, medium, and apparatus encoding and/or decoding an audio signal to surround data. While encoding spatial information, which can up-mix an audio signal to a surround signal, to extension data, a length of a payload corresponding to the spatial information is encoded and a payload of the spatial information is decoded using the length of the payload. Accordingly, compatibility of the spatial information can be provided, and the spatial information can be transmitted by effectively embedding the spatial information.

Abstract: A Unified Speech and Audio Codec (USAC) for adjusting an overlap area of a window based on a transition is provided. To increase an encoding efficiency, encoding may be performed by overlapping relatively long windows. Additionally, when a transition is generated between frames, an overlap area of a window may be reduced based on the transition, thereby preventing a noise from occurring due to the transition.

Abstract: A source sampling rate is associated with first or second groups of sampling rates. A playback rate is determined by: (a) selecting the source sampling rate if the source sampling rate is supported by a playback environment; (b) otherwise if there is a highest first rate from the first or second groups of playback sampling rates which is supported by the playback environment and is lower than the source sampling rate, selecting the first rate; (c) otherwise if there is a slowest second rate from the group that the source sampling rate is associated with that is supported by the playback environment and is higher than the source sampling rate, selecting the second rate; (d) otherwise selecting the slowest sampling rate supported by the playback environment from the group that the source sampling rate is not associated with as the playback rate.

Each random access unit includes a number of frames and at least one of the frames being a random access frame. Each random access frame is a frame encoded such that previous frames are not necessary to decode the random access frame. The random access unit information indicates a distance between at least two of the random access frames in bytes.

A method for providing value-added information to a user of a communication device and a communication system for providing value-added information are also disclosed.
