Abstract: A method and apparatus for performing motion estimation in a digital video system is disclosed. Specifically, the present invention discloses a system that quickly calculates estimated motion vectors in a very efficient manner. In one embodiment, a first multiplicand is determined by multiplying a first display time difference between a first video picture and a second video picture by a power of two scale value. This step scales up a numerator for a ratio. Next, the system determines a scaled ratio by dividing that scaled numerator by a second first display time difference between said second video picture and a third video picture. The scaled ratio is then stored calculating motion vector estimations. By storing the scaled ratio, all the estimated motion vectors can be calculated quickly with good precision since the scaled ratio saves significant bits and reducing the scale is performed by simple shifts.

Abstract: A decoding method decodes a bit stream in an image decoding apparatus. The method includes receiving a weight parameter that is added to a luma quantization parameter as the bit stream. The method also includes decoding, in a decoding unit in the image decoding apparatus, the bit stream, and generating a luma component of quantized coefficients and a chroma component of quantized coefficients. Further, the method includes performing, in a dequantization unit in the image decoding apparatus, dequantization on the luma component of quantized coefficients using the luma quantization parameter and the chroma component of quantized coefficients using a chroma quantization parameter calculated on the basis of the luma quantization parameter weighted by an add operation of the weight parameter. In addition, the method includes performing, in a transform unit in the image decoding apparatus, an inverse orthogonal transform.

Abstract: New capabilities will allow conventional broadcast transmission to be available to mobile devices. A method is described including the steps of receiving data, encoding the data using a first encoding process, inserting training data into the encoded data, and encoding the encoded data and the training data using a second encoding process. An apparatus is also described including a first encoder receiving at least a portion of data and encoding the portion of data using a first encoding process, a training data inserter inserting training data into the first encoded data, and a second encoder encoding the first encoded data and the training data using a second encoding process.
