  • SERVER-SIDE ADAPTIVE VIDEO PROCESSING
    Publication number: 20150243243
    Abstract: Adaptive video processing for a target display panel may be implemented in or by a server/encoding pipeline. The adaptive video processing methods may obtain and take into account video content and display panel-specific information including display characteristics and environmental conditions (e.g., ambient lighting and viewer location) when processing and encoding video content to be streamed to the target display panel in an ambient setting or environment. The server-side adaptive video processing methods may use this information to adjust one or more video processing functions as applied to the video data to generate video content in the color gamut and dynamic range of the target display panel that is adapted to the display panel characteristics and ambient viewing conditions.

  • Implantable Medical Device and System
    Publication number: 20150209590
    Abstract: The implantable medical device is for implantation into a patient's body and is wirelessly powered by an external control device. The implantable medical device is induced by an AC electromagnetic field of the external control device through an inductive coil. A rectifier converts the AC electromagnetic field into a DC current. A detector detects a voltage value of the DC current, and a processor produces a first piece of status information accordingly. A transceiver receives and relays the first piece of status information to the external control device so as to monitor the power consumption of the implantable medical device when it is wirelessly powered.

  • VIDEO PROCESSORS FOR PRESERVING DETAIL IN LOW-LIGHT SCENES
    Publication number: 20140321534
    Abstract: Video coding systems and methods are provided that protect against various artifacts (e.g., banding artifacts) in decoded frame content. The embodiments to protect against introducing artifacts include pre-processing the input video frame, controlling the encoding parameters and/or post-processing the decoded video frame. A method for encoding a frame may include calculating a dark-scene score for the frame based on measured statistics of the frame. The dark-scene score may be compared to a threshold to determine if the banding artifacts may be present in the frame. Based on the comparison, filtering parameters for the frame may be altered to reduce the amount of noise filtered from the frame. The frame may be filtered based on the altered filtering parameters and encoded.

  • ADAPTIVE STREAMING TECHNIQUES
    Publication number: 20140241415
    Abstract: Systems and methods are presented for minimizing the suddenness and immediacy of changes to the video quality perceived by users due to bandwidth fluctuations and transitions between different bitrate streams. A method may include identifying an upcoming bitrate change in a bitstream and a nearest scene cut boundary from sync frame scene cut tags included in the bitstream. The method may include calculating whether waiting until the identified nearest scene cut boundary before changing the bitrate will cause the buffer to drop below a threshold. When the buffer is calculated to not drop below the threshold, the method may postpone the upcoming bitrate change until the identified nearest scene cut boundary.

  • ENCODING TECHNIQUES FOR BANDING REDUCTION
    Publication number: 20140029663
    Abstract: Video encoders often produce banding artifacts on areas with smooth gradients and low levels of detail/noise. In this disclosure, a video encoding system identifies the banded areas and adjusts coding parameters accordingly. The video coder may include a pre-coding banding detector and a post-coding banding detector. The pre-coding detector may identify regions in the input picture with smooth gradients that are likely to have banding artifacts after encoding. The post-coding detector may identify regions in the reconstructed picture with visible banding. Usage of pre-coding detector and/or post-coding detector depends on how an encoder operates. In a single-pass encoding or during the first pass of a multi-pass encoding, the pre-coding detection maps are used. During picture re-encoding or during later passes of a multi-pass encoding, the post-coding detector maps are used.

  • TECHNIQUES FOR ADAPTIVE VIDEO STREAMING
    Publication number: 20130329781
    Abstract: A vide coding server may code a common video sequence into a plurality of coded data streams, each coded data stream representing the video sequence coded using coding parameters tailored for a respective transmission bit rate. The coding may cause a set of transmission units from among the coded data streams to include coded video data from a common point of the video sequence, and a first coded frame of each transmission unit of the set to be a synchronization frame. A manifest file may be built representing an index of transmission units of the respective coded data streams. The coded data streams and manifest file may be stored by the server for delivery to a client device. During download and decode, the chunks may be decoded efficiently even when switching among streams because the first frame in each chunk is a synchronization frame.

  • SIGNAL SHAPING TECHNIQUES FOR VIDEO DATA THAT IS SUSCEPTIBLE TO BANDING ARTIFACTS
    Publication number: 20130235942
    Abstract: Video coding systems and methods protect against banding artifacts in decoded image content. According to the method, a video coder may identify, from content of pixel blocks of a frame of video data, which pixel blocks are likely to exhibit banding artifacts from the video coding/decoding processes. The video coder may assemble regions of the frame that are likely to exhibit banding artifacts based on the identified pixel blocks' locations with respect to each other. The video coder may apply anti-banding processing to pixel blocks within one or more of the identified regions and, thereafter, may code the processed frame by a compression operation.
