摘要： A two-channel phase-amplitude stereo encoding and decoding scheme enabling flexible and spatially accurate interactive 3-D audio reproduction via standard audio-only two-channel transmission. The encoding scheme allows associating a 2-D or 3-D positional localization to each of a plurality of sound sources by use of frequency independent inter-channel phase and amplitude differences. The decoder is based on frequency-domain spatial analysis of 2-D or 3-D directional cues in a two-channel stereo signal and re-synthesis of these cues using any preferred spatialization technique, thereby allowing faithful reproduction of positional audio cues and reverberation or ambient cues over arbitrary multi-channel loudspeaker reproduction formats or over headphones, while preserving source separation despite the intermediate encoding over only two audio channels.

摘要： There is provided a system and method for video frame marking. It is preferable that a tagged video frame is visually perceptible in the set of chronologically ordered video frames shown in the display. The selection of each video frame preferably causes playback of an excerpt of the video with a duration of the common predetermined interval. The video frame may denote a scene from a portion of the excerpt of the video, such as, for example, start, middle and end. It is advantageous that the excerpts of the video of each tagged video frame is combined using the user interface to generate a concise representation of the video. The concise representation of the video may be in a form where excerpts of the video of each of the tagged video frames are played back at a normal rate while excerpts of the video of each of other video frames are played back at an accelerated rate.

摘要： There is provided a dock without a power source for a portable digital device with at least one integrated speaker driver. The dock may include a platform for placement of the portable digital device; a protrusion located at the platform for connection of the portable digital device with the dock with the protrusion including a slot for egress of air from at least one hole in a casing of the portable digital device to the dock; and at least one primary chamber to receive air from the portable digital device with the at least one primary chamber having a vented port for the egress of air. Advantageously, sound from the at least one integrated speaker driver is amplified when the portable digital device is connected to the dock. The connection of the portable digital device with the dock may be securable. A horn may be included in an exterior facing opening of the vented port, as the horn advantageously improves aspects of sound such as, for example, sound directivity, radiation efficiency or both of the aforementioned.
