  • Publication number: 20250385153
    Abstract: The subject technology is directed to a semiconductor device. In an embodiment, the semiconductor device comprises an interposer, which comprises a first side and a second side. The first side is opposite the second side. The device further comprises a first circuit coupled to the first side and a second circuit coupled to the second side. The device further comprises a first layer coupled to the first circuit and a second layer coupled to the second circuit. The second layer is configured to dissipate heat generated by the second circuit. This configuration enhances thermal management by providing a direct thermal path for heat dissipation, improving the overall efficiency and reliability of the semiconductor device. Additionally, the elimination of thermal vias simplifies the PCB layout, allowing for more compact and cost-effective designs.

  • Patent number: 12149699
    Abstract: Techniques are disclosed by which a coding parameter is determined to encode video data resulting in encoded video data possessing a highest possible video quality. Features may be extracted from an input video sequence. The extracted features may be compared to features described in a model of coding parameters generated by a machine learning algorithm from reviews of previously-coded videos, extracted features of the previously-coded videos, and coding parameters of the previously-coded videos. When a match is detected between the extracted features of the input video sequence and extracted features represented in the model, a determination may be made as to whether coding parameters that correspond to the matching extracted feature correspond to a tier of service to which the input video sequence is to be coded.

  • Patent number: 11093752
    Abstract: Techniques are disclosed for managing display of content from multi-view video data. According to these techniques, an object may be identified from content of the multi-view video. The object's location may be tracked across a sequence of multi-view video. The technique may extract a sub-set of video that is contained within a view window that is shifted in an image space of the multi-view video in correspondence to the tracked object's location. These techniques may be implemented either in an image source device or an image sink device.

  • Patent number: 10873763
    Abstract: Techniques are disclosed for coding high dynamic range (HDR) data. According to such techniques, HDR data may be converted to a domain of uniform luminance data. The uniform domain data may be coded by motion compensated predictive coding. The HDR data also may be coded by motion compensated predictive coding, using a coding parameter that is derived from a counterpart coding parameter of the coding of the uniform domain data. In another technique, HDR data may be coded using coding parameters that are derived from HDR domain processing but distortion measurements may be performed in a uniform domain.

    Abstract: Systems and methods are disclosed for reshaping HDR video content to improve compression efficiency while using standard encoding/decoding techniques. Input HDR video frames, e.g., represented in an IPT color space, may be reshaped before the encoding/decoding process and the corresponding reconstructed HDR video frames may then be reverse reshaped. The disclosed reshaping methods may be combinations of scene-based or segment-based methods.
