The statistics generally characterize how the current picture was encoded. The coefficients may correspond to a plurality of coding modes. | 06-05-2014 |
20140169457 | PERFORMANCE CONTROL IN VIDEO ENCODING - An apparatus having a circuit is disclosed. The circuit may be configured to (i) generate a complexity value by encoding a current picture in a video signal, where the current picture is encoded using a current one of a plurality of configurations, (ii) calculate an estimate in response to the complexity value and (iii) reconfigure the encoding into a new one of the configurations in response to the estimate relative to one or more thresholds. The configurations may include a normal configuration and one or more simplified configurations. The estimate generally describes a computational stress that the encoding of the current picture placed on the circuit. The new configuration may be different from the current configuration. | 06-19-2014 |
20140169468 | PICTURE REFRESH WITH CONSTANT-BIT BUDGET - An apparatus having a memory and a circuit is disclosed. The memory may be configured to store multiple reference pictures. The circuit may be configured to (i) generate multiple compressed pictures by compressing each uncompressed picture using the reference pictures and a constant-bit budget and (ii) generate multiple new reference pictures in the memory by decompressing the compressed pictures. A subset of the compressed pictures may each be divided into a first area, a second area and a third area. The first areas are generally intra-encoded. Each motion vector of the second areas in the compressed pictures may point outside the third areas of the reference pictures. The first areas in the reference pictures that were decompressed from the subset of the compressed pictures may incorporate content from the third areas. | 06-19-2014 |
20140204995 | EFFICIENT REGION OF INTEREST DETECTION - An apparatus having a circuit is disclosed. The circuit may be configured to (i) calculate a plurality of complexity values while compressing a current picture in a video signal. Each complexity value generally characterizes how a corresponding one of a plurality of blocks in the current picture was compressed. The circuit may also be configured to (ii) adjust the complexity values below a first threshold to a default value and (iii) generate a region of interest by grouping the blocks having non-default values of the complexity values above a second threshold. | 07-24-2014 |
20150163363 | LOW COMPLEXITY TONE/VOICE DISCRIMINATION METHOD USING A RISING EDGE OF A FREQUENCY POWER ENVELOPE - An apparatus comprising a decision circuit, a detector circuit and a processing circuit. The decision circuit may be configured to generate a confirmation signal in response to a first lock signal and a second lock signal. The detector circuit may be configured to generate the first lock signal in response to a filtered version of an input signal being above a threshold. The processing circuit may be configured to generate the second lock signal in response to a power signal received from the detector circuit. The processing circuit generates the second lock signal by analyzing the rising edge of a frequency power envelope of the power signal. | 06-11-2015 |

20120158706 | GRAPHICALLY REPRESENTING ASSOCIATIONS BETWEEN REFERENTS AND STORIES - Systems and methods are provided for graphically representing associations between one or more stories and one or more referents of interest. In some embodiments, a score may be determined for each of a set of stories based at least in part on a number of associations between the given story and one or more referents of interest. A graphical representation of the stories may then be presented for display. The graphical representation may include indicia, where each indicium graphically indicates the strength of association between a given story and the one or more referents of interest. The strength of association for a given story may be determined, for example, based at least in part on the determined score for the story. | 06-21-2012 |
20120158707 | GRAPHICALLY REPRESENTING ASSOCIATIONS BETWEEN REFERENTS AND POINTS IN A STORY - Systems and methods are provided for graphically representing associations between one or more points in a story and one or more referents of interest. In some embodiments, a score may be determined for each of a set of points in a story based at least in part on a number of associations between the given point in the story and one or more referents of interest. A graphical representation of the points in the story may then be presented for display. The graphical representation may include indicia, where each indicium graphically indicates the strength of association between a given point in the story and the one or more referents of interest. The strength of association for a given point in the story may be determined, for example, based at least in part on the determined score for the point. | 06-21-2012 |
20150127639 | GRAPHICALLY REPRESENTING ASSOCIATIONS BETWEEN REFERENTS AND STORIES - Systems and methods are provided for graphically representing associations between one or more stories and one or more referents of interest. In some embodiments, a score may be determined for each of a set of stories based at least in part on a number of associations between the given story and one or more referents of interest. A graphical representation of the stories may then be presented for display. The graphical representation may include indicia, where each indicium graphically indicates the strength of association between a given story and the one or more referents of interest. The strength of association for a given story may be determined, for example, based at least in part on the determined score for the story. | 05-07-2015 |

20140039887 | IDENTIFYING CORRESPONDING REGIONS OF CONTENT - A content alignment service may generate content synchronization information to facilitate the synchronous presentation of audio content and textual content. In some embodiments, a region of the textual content whose correspondence to the audio content is uncertain may be analyzed to determine whether the region of textual content corresponds to one or more words that are audibly presented in the audio content, or whether the region of textual content is a mismatch with respect to the audio content. In some embodiments, words in the textual content that correspond to words in the audio content are synchronously presented, while mismatched words in the textual content may be skipped to maintain synchronous presentation. Accordingly, in one example application, an audiobook is synchronized with an electronic book, so that as the electronic book is displayed, corresponding words of the audiobook are audibly presented. | 02-06-2014 |
20140040713 | SELECTING CONTENT PORTIONS FOR ALIGNMENT - Generally described, a content alignment service may generate content synchronization information to facilitate the synchronous presentation of corresponding audio content and textual content. In some embodiments, portions of body text (as opposed to front matter, such as a table of contents; or back matter, such as an index) in the textual content are identified and synchronized with corresponding audio content. In one example application, an audiobook may be synchronized with an electronic book. As the body text portions of the electronic book are consumed, corresponding words of the audiobook may be audibly presented. | 02-06-2014 |
