摘要： An image coded data re-encoding apparatus (30) which generates in an image coded data analyzer (310) coded data after signal processing (221) by performing a first digital signal processing on first image coded data (220), supplies an image coded data synthesizer (320) with the coded data after signal processing (221) and multiple signals (222) associated with the first image coded data, and generates in the image coded data synthesizer (320) a second image coded data (240) by performing on the coded data after signal processing (221) a second digital signal processing based on multiple signals (222). The second image coded data is generated without once decoding the first image coded data. This makes it possible to prevent degradation in image quality, delay involved in the transform and an increase of the device size.

摘要： An adaptive blocking coding system selects an effective blocking of an input image signal to be encoded in accordance with the correlation between fields, even if motion is detected between the fields. The blocking patterns include an individual field blocking, a non-interlace blocking, a split blocking and an inverted split blocking. Further, the coding system searches for motion from both odd and even fields of a frame for producing a motion compensated prediction signal in order to provide high-efficient coding.

摘要： A method and a video decoder for decoding an encoded bitstream of video data in a picture encoding and decoding system are disclosed. The video decoder includes a motion compensation unit for calculating a position for a sample image portion using an encoded bitstream of video data having a motion vector and rounding information. The calculated position of a sample image is rounded with the rounding information. The rounding information indicates the accuracy for rounding, and it is decoded from the bitstream. An image reconstruction unit reconstructs a decoded image portion of the video data from the sample image portion.
