    Abstract: The present invention provides a transcoding architecture and a consumer set-top box with storage capability that is based on the transcoding architecture and capable of operating efficiently in an all-digital environment. In a preferred embodiment, a digital-VIDEO DEVICE employs an MPEG-2 compliant transcoder that includes a simplified cascaded decoder and encoder, and is capable of performing determinable bitrate re-encoding without conducting motion estimation. During recording, the decoder receives and processes a compressed source bitstream, producing a decoded bitstream that includes reconstructed video and preserved motion vectors. The encoder “re-encodes” the decoded bitstream using the preserved motion vectors and performs any applicable bitrate modifications. The re-encoded bitstream is then stored.

    Abstract: In one embodiment, a method for encoding or decoding video content is provided. The method includes receiving a plurality of full-pel pixel values. A set of coefficients is determined for an interpolation filter to interpolate a sub-pel pixel value for a motion compensation operation. Different coefficients are assigned to weight the plurality of full-pel pixel values in different operations in the interpolation filter. The sub-pel pixel values from the different operations are determined. Then, the method outputs the interpolated sub-pel pixel value for use in the motion compensation operation.

    Abstract: In one embodiment, a spatial merge mode or a temporal merge mode for a block of video content may be used in merging motion parameters. Both spatial and temporal merge parameters are considered concurrently and do not require utilization of bits or flags or indexing to signal a decoder. If the spatial merge mode is determined, the method merges the block of video content with a spatially-located block, where merging shares motion parameters between the spatially-located block and the block of video content. If the temporal merge mode is determined, the method merges the block of video content with a temporally-located block, where merging shares motion parameters between the temporally-located block and the block of video content.

According to the invention, the highest amount of L-lactic acid produced from glucose is 173 g/L, the optical purity is over 99%, the yield is up to 0.98, and the productivity is up to 2.4 g/L per hour. The highest amount of L-lactic acid produced from xylose is 195 g/L, the optical purity is over 99%, the yield is up to 0.98, and the productivity is up to 2.7 g/L per hour. The highest amount of L-lactic acid produced from reducing sugars in xylitol byproducts is 106 g/L, the optical purity is over 99%, and the productivity is up to 2.08 g/L per hour. The B. coagulans strains XZL4 (DSM No. 23183) and XZL9 (DSM No. 23184) of the invention can directly utilize various reducing sugars in xylitol byproducts to produce high amounts of L-lactic acid, which improves the production efficiency at low costs, and the strains are, thus, appropriate for industrial productions.
