  • Patent number: 10958926
    Abstract: The invention is a novel watermark in a media sequence and systems and methods for embedding and detecting the watermark. Different watermarks from a watermark set of pseudo random watermarks are selected (randomly or by a selection pattern) and each selected watermark is embedded in a different selected I-frame set of the media stream. Identifying the known sequence of watermarks in the stream of I-frames of a copy can identify the video stream from which the copy originates.

  • Patent number: 10379813
    Abstract: Embodiments may include receiving an input block of data having one or more rows wherein each row includes one or more elements. Embodiments may further include adjusting the input block of data to generate a two-dimensional sorted block of data and identifying at least one position within the two-dimensional sorted block of data that cannot contain a median value or a desired Nth sorted value. Embodiments may also include sorting the two-dimensional block of data along one or more columns to obtain one or more candidate elements that contain the median value or the desired Nth sorted value. Embodiments may include discarding at least one non-candidate element to generate one or more remaining elements and rearranging the one or more remaining elements such that a number of diagonal elements form a column. Embodiments may also include iteratively repeating some of the above operations until a desired value is identified.

  • Patent number: 9877047
    Abstract: Sampled data is packaged in checkerboard format for encoding and decoding. The sampled data may be quincunx sampled multi-image video data (e.g., 3D video or a multi-program stream), and the data may also be divided into sub-images of each image which are then multiplexed, or interleaved, in frames of a video stream to be encoded and then decoded using a standardized video encoder. A system for viewing may utilize a standard video decoder and a formatting device that de-interleaves the decoded sub-images of each frame reformats the images for a display device. A 3D video may be encoded using a most advantageous interleaving format such that a preferred quality and compression ratio is reached. In one embodiment, the invention includes a display device that accepts data in multiple formats.

  • Patent number: 9253108
    Abstract: Systems and methods for optimizing system performance of capacity and spectrum constrained, multiple-access communication systems by selectively discarding packets are provided. The systems and methods provided herein can drive changes in the communication system using control responses. One such control responses includes the optimal discard (also referred to herein as “intelligent discard”) of network packets under capacity constrained conditions. Some embodiments inspect a video stream to determine priorities for various elements of the video stream. The elements may be discarding using the priorities. In various embodiments, the elements include frames, slices, macroblocks, and data partitions.

  • Patent number: 8983094
    Abstract: An all-in-one audio system includes an audio chip, an audio interface, first and second audio signal amplifiers, a speaker, a woofer, a multi-function controller, a high definition multimedia interface (HDMI), and a switch. The multi-function controller is connected to the audio chip, the switch, the audio interface, the first and second audio signal amplifiers, and the HDMI. When the multi-function controller detects a high definition multimedia signal through the HDMI, the multi-function controller turns off the switch, decodes the high definition multimedia signal into an audio signal, and transmits the audio signal to the audio interface, and the first and second audio signal amplifiers. The first and second audio signal amplifiers amplify the audio signal and output the amplified audio signal to the speaker and woofer.

  • Patent number: RE41001
    Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram expressed at least in the polar coordinate system. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into low and high frequency band components which are designated as first and second data streams respectively.
