20130170551 | Halo Reduction in Frame-Rate-Conversion Using Hybrid Bi-Directional Motion Vectors for Occlusion/Disocclusion Detection - A frame-rate converter reduces halo artifacts along edges of moving objects. Halo artifacts occur on interpolated frames where a moving object covers and uncovers pixels along its edges. Motion estimation among three original frames produces hybrid direction motion vectors that are bi-directional for background and objects, but are unidirectional for covered and uncovered regions, since motion vectors with large matching errors are deleted. Covered regions in the interpolated frame are detected as intersecting only a forward but no backward hybrid motion vector. Bi-directional motion estimation from the hybrid motion vectors of two original frames produces refined motion vectors for the interpolated frame. Refined motion vectors in the covered regions are deleted and replaced with hybrid motion vectors from the original frames. Hybrid motion vectors from the original frames are assigned to the critical covered regions rather than using interpolated vectors in the covered regions, reducing halo artifacts. | 2013-07-04 |

20130170557 | Method and System for Video Coding with Noise Filtering - Techniques are discussed herein for providing mechanisms for coding and transmitting high definition video, e.g., over low bandwidth connections. In particular, foreground-objects are identified as distinct from the background of a scene represented by a plurality of video frames. In identifying foreground-objects, semantically significant and semantically insignificant movement (e.g., non-repetitive versus repetitive movement) is differentiated. For example, the swaying motion of a tree's leaves being minor and repetitive, can be determined to be semantically insignificant and to belong in a scene's background. Processing of the foreground-objects and background proceed at different update rates or frequencies. For example, foreground-objects can be updated 30 or 60 times per second. By contrast, a background is updated less frequently, e.g., once every 10 seconds. In some implementations, if no foreground-objects are identified, no live video is transmitted (e.g., if no motion is detected, static images are not configured to be repeatedly sent). Techniques described herein take advantage of the realization that, in the area of surveillance and wireless communications, updating video of semantically significant movement at a high frame rate is sufficient. | 2013-07-04 |

When the valid data is transmitted, the transmitting circuit transmits a symbol indicating a packet start position, selects second channel coding (e.g. 64B/66B coding) having less coding loss than the first channel coding, and transmits the valid data encoded using the second channel coding. Upon reception of the symbol indicating the packet start position, the receiving circuit switches to reception using the second channel coding and receives the valid data. | 2013-07-04 |
20130170580 | EMPHASIS CIRCUIT AND TRANSMITTER - An emphasis circuit includes: an applying circuit to add an emphasis signal to an input differential signal; a feedback path to feed back a differential output of the applying unit; a comparing circuit to compare a direct current component level of a positive phase signal and of a negative phase signal of the differential signal; a direct current component level controlling circuit to control a direct current component level of at least one of the positive phase signal and the negative phase signal; a delay unit circuit to add a delay to at least one of the fed-backed differential signal to generate the emphasis signal and inputs the emphasis signal into the applying unit; and a dummy load coupled to a positive phase signal output or a negative phase signal output of the applying unit. | 2013-07-04 |
20130170581 | QUADRATURE DIGITAL-IF TRANSMITTER WITHOUT INTER-STAGE SAW FILTER AND DEVICES USING SAME - An RF transmitter comprises a digital-to-IF circuit block configured to receive a digital in-phase baseband signal and a digital quadrature baseband signal and to up-convert the digital in-phase and quadrature baseband signals to a digital in-phase IF signal and to a digital quadrature IF signal. The wireless RF transmitter further comprises an IF-to-RF circuit block configured to convert the digital in-phase and quadrature IF signals to analog signals and to up-convert the analog in-phase and quadrature IF signals to an RF output signal. The digital-to-IF circuit block comprises pre-compensation circuitry configured to reduce analog impairments associated with the IF-to-RF circuit block. | 2013-07-04 |
