Abstract: A method and a system are provided for segmenting a multimedia content. The method estimates a count of a plurality of multimedia segments in the multimedia content, and a duration of each of the plurality of multimedia segments in the multimedia content. The method determines a cost function associated with a multimedia segment from the plurality of multimedia segments, based on the count of the plurality of multimedia segments, and the duration of each of the plurality of multimedia segments. The method further determines an updated count of the plurality of multimedia segments, and an updated duration of each of the plurality of multimedia segments until the cost function satisfies a pre-defined criteria. Based on the updated count of the plurality of multimedia segments, and the updated duration of each of the plurality of multimedia segments, the method segments the multimedia content into the plurality of multimedia segments.

Abstract: Embodiments are directed to a companding method and system for reducing coding noise in an audio codec. A compression process reduces an original dynamic range of an initial audio signal through a compression process that divides the initial audio signal into a plurality of segments using a defined window shape, calculates a wideband gain in the frequency domain using a non-energy based average of frequency domain samples of the initial audio signal, and applies individual gain values to amplify segments of relatively low intensity and attenuate segments of relatively high intensity. The compressed audio signal is then expanded back to the substantially the original dynamic range that applies inverse gain values to amplify segments of relatively high intensity and attenuating segments of relatively low intensity. A QMF filterbank is used to analyze the initial audio signal to obtain a frequency domain representation.

The method further includes determining one or more segments of the multimedia content, based on the identified set of key-phrases, wherein a segment of the determined one or more segments comprises a subset of key-phrases from the set of key-phrases. The method further includes selecting at least a key-phrase from the subset of key-phrases of each of the corresponding one or more segments. The method further includes generating the table of content based on the selected key-phrase from each of the one or more segments, wherein the selected key-phrase from each of the one or more segments in the generated table of content is utilized to navigate through the multimedia content.

Abstract: Systems and methods are described for switching between lossy coded time segments and a lossless stream of the same source audio. A decoder may receive lossy coded time segments that include audio encoded using frequency-domain lossy coding. The decoder may also receive a lossless stream, which the decoder plays back, that includes audio from the same source encoded using lossless coding. In response to receiving a determination that network bandwidth is constrained, the decoder may generate an aliasing cancellation component based on a previously-decoded frame of the lossless stream, which may be added to a lossy time segment at a transition frame. The sum of the aliasing cancellation component and the lossy time segment may be normalized using a weight caused by an encoding window. Audio playback of the lossy coded time segments may then be provided, beginning with the aliasing-canceled transition frame.

Abstract: Work can be migrated between processor cores. For example, a thread causing a heavy load on a first core can be detected. A power control unit can determine to migrate the thread from the first less-efficient core to the second more-efficient core. The power control unit can request that the first core and the second core transition to a low-power state (e.g., a sleep state, a C6 power state, etc.). The first core can transfer its software context to a first core software context storage, halt and quiesce. The second core can halt and quiesce. The software context from the first core software context storage can be transferred to a second core software context storage of the second core. A processing core identifier of the first core can be assigned to the second core. The power control unit can then request the second core to transition to an active state (such as a C0 state).

Abstract: The present disclosure relates to methods for processing a decoded audio signal and for selectively applying speech/dialog enhancement to the decoded audio signal. The present disclosure also relates to a method of operating a headset for computer-mediated reality. A method of processing a decoded audio signal comprises obtaining a measure of a cognitive load of a listener that listens to a rendering of the audio signal, determining whether speech/dialog enhancement shall be applied based on the obtained measure of the cognitive load, and performing speech/dialog enhancement based on the determination. A method of operating a headset for computer-mediated reality comprises obtaining eye-tracking data of a wearer of the headset, determining a measure of a cognitive load of the wearer of the headset based on the eye-tracking data, and outputting an indication of the cognitive load of the wearer of the headset.

Abstract: A method, a system and a computer program product are disclosed for enhancing an audio signal in relation to a hearing impairment. An input signal is obtained comprising input sub-band signals in a frequency range comprising a source range and a target range. The input sub-band signals in the source range are selectively transposed into transposed sub-band signals in the target range according to a predefined transposing rule. A masking threshold is determined based on a predefined perceptual model and perceptually relevant sub-band signals of the transposed sub-band signals in the target range exceeding the masking threshold are detected. Input sub-band signals in the target range are selectively replaced with corresponding detected perceptually relevant sub-band signals of the transposed sub-band signals in the target range.

Abstract: Features are extracted from visual and audio modalities of a video to infer the location of figures/tables/equations/graphs/flow-charts determined as video anchor points which are highlighted on the video timeline to enable quick navigation and provide a quick summary of the video. A voice-based mechanism navigates to a point-of-interest in the video. In case of bandwidth-constrained settings, videos are often played at a very low resolution (quality), and often users need to increase video resolution manually to understand content presented in the figures. Using the automatic identification of these aforementioned anchored points, the resolution can be changed dynamically during streaming a video, which will provide a better viewing experience.
