    摘要: Technologies may provide for detecting, validating, or confirming the validity of a handwritten signature. A logic architecture may be employed to detect a digital handwritten signature and validation data associated with a signature event, and to send the signature and the validation data to a trusted server. The logic architecture may validate the digital handwritten signature based on the signature and the validation data. Additionally, the logic architecture may present the digital handwritten signature with a reference to confirm the validity of the signature. The reference may be associated with identifying information corresponding to the event to confirm the validity of the signature.

    摘要: A method and apparatus are provided for encoding with hypothetical reference decoder compliant bit allocation. The apparatus includes an encoder (100) for encoding image data for a picture in a resultant bitstream by controlling a bit allocation during the encoding of the image data responsive to satisfying requirements for a subsequent decoding of the bitstream. The requirements relate to preventing at least one of an underflow condition and an overflow condition in a buffer during the subsequent decoding of the bitstream.

    摘要: Method and apparatuses are provided to enable bi-directional prediction (or bi-prediction) within P slices. A bi-predicted P slice is introduced herein as a new slice type in addition to existing I, P and B slices. A benefit of the new bi-predicted P slice is that it enables a video encoder to support temporal scalability without the need to use B pictures. Bi-predicted P slices enable the definition of a hierarchical GOP structure, which is a common method to allow temporal scalability in a video encoder. Another advantage of bi-predicted P slices is that it can improve coding efficiency over uni-directional P slices for some particular video content frames.

    摘要: The present invention relates to a full-reference (FR) objective method for assessing perceptual quality of decoded video frames in the presence of packet losses and coding artifacts. A method of assessing perceptual quality is provided. First, a value indicating an amount of distortion in a corresponding portion is accessed. Then, that value is classified as packet-loss distortion or coding-artifact distortion. Next, the classified value is modified to account for visibility differences of the human visual system, based on the classification, and then the modified values are combined for the multiple portions, to form a value indicating a total amount of distortion for the multiple portions.

    摘要: A method of encoding video wherein multiple threads of GOPs are encoding in parallel from a buffer in a single pass. In the buffer GOPs having fewer frames than a low frame threshold at the end of a scene are merged with a preceding GOP. Hypothetical reference decoder (HRD) information is stored in the buffer for each GOP and HRD information for neighboring GOPs are merged in the buffer.

    摘要: A resistive circuit includes a first terminal and a second terminal and polycrystalline first and second resistive segments coupled between the first and second terminals. A third terminal A is coupled to the first resistive segment, and a third terminal B is coupled to the second resistive segment. The third terminal A has a first voltage with respect to the first terminal, and the third terminal B has a second voltage with respect to the second terminal. With this arrangement, the non-linearity of resistance of the first resistive segment at least partially compensates for non-linearity of resistance of the second resistive segment.
