    摘要: A cost function for use in an encoding mode decision for encoding a section of a digital picture is determined using a non-default relationship between Lagrange multiplier (λ) values and quantization parameter (QP) values to determine the cost function when a number of bits per section (NBS) of the digital picture is in a predetermined range and determined using a default relationship between the A, values and the QP values to determine the cost function otherwise. The determined cost function is used to make the section encoding mode decision and the section is encoded according to the encoding mode decision. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

    摘要: An encoding system may include a video source that provides video data to be coded, a video coder, a transmitter, and a controller to manage operation of the system. The controller may control the video coder to code and compress the image information from the video source into video data, based upon one or more motion prediction parameters. The transmitter may transmit the video data. A decoding system may decode the video data based upon the motion prediction parameters.

    摘要: A system and method are disclosed for transcoding a video clip. In one implementation, a computer system determines N frames at which to divide a video clip into N+1 consecutive chunks, where N is a positive integer, and where the frames are determined based on the image content of the video clip, a minimum chunk size, and a maximum chunk size. Each of the N+1 chunks is provided to a respective processor for transcoding, and a transcoded video clip is generated from the transcoded N+1 chunks.

    摘要: According to an embodiment, an encoding device includes a processor and a memory. The processor applies a filter to first and second images included in moving image (video) data. The processor encodes the first and second images to which the filter has been applied and generates encoded data. The processor generates, on the basis of an encoding completion target time of the first image included in the moving image data, a target value of an encoding time spent for encoding the second image to be encoded after the first image. The processor controls the applying of the filter for the second image depending on the target value of the encoding time.
