Example embodiments provide scheduling a plurality of ads to be shown to a plurality of viewers of a multimedia network. One example embodiment includes determining target view rates for each of the plurality of ads based on expected revenue associated with each of the plurality of ads, determining, for each of the plurality of ads, a queue value based on a target view rate and an actual view rate associated with the ad, the actual view rate being a number of views of the ad in a previous time slot, and selectively showing ads, from among the plurality of ads, to the plurality of viewers based on the queue values.

The present invention discloses a system and method for providing a rate control to an encoder, e.g., a H.264/MPEG-4 AVC compliant encoder. Specifically, the rate control method computes a target rate for a segment, where the segment comprises at least one slice of macroblocks. In turn, a target rate is computed for the at least one slice of macroblocks from the target rate for the segment. In turn, a quantization parameter (QPj) is computed for a macroblock (j) of the macroblocks from the target rate for the at least one slice. Finally, the macroblock (j) is encoded in accordance with said quantization parameter (QPj).

A method and system of transform-based encoding, decoding, and bitstream generation of digital video content is disclosed. The digital video content comprises a stream of pictures, slices, or macroblocks which can each be intra, predicted or bi-predicted pictures. The pictures, slices, or macroblocks comprise blocks of pixels. The method and system comprises scanning frequency coefficients from each of the block's two dimensional array of frequency coefficients in a manner that is vertically biased, producing a one dimensional array of frequency coefficients. The method and system also provide for scanning/assigning frequency coefficients from a one dimensional array of frequency coefficients, producing a two dimensional array of frequency coefficients.

A method and apparatus for determining whether a block of pixels will likely contain all zero coefficients for various video encoding functions are disclosed. For example, the method receives or obtains a block of pixels from an input image and computes a measure for the block of pixels, where the measure comprises at least one of: a distortion measure or a maximum of absolute values of residuals measure. The method then determines whether the block of pixels contains all zero coefficients in accordance with the measure.

A pressure regulator apparatus and method for controlling the pressure in a pressure system is disclosed. The pressure regulator broadly includes a pressure transducer and a regulator control circuit. The pressure transducer measures the pressure of the pressure system, and the regulator control circuit controls the pressure in the pressure system in response to the pressure reading of the pressure transducer. The regulator control circuit compares the measured pressure to a predetermined set-point value for maintaining the pressure within a predetermined optimal pressure range.

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.
摘要:
The invention is concerned with the strains of B. coagulans for lactic acid production and the related methods, in which the carbon sources are pentose or hexose or the agricultural or industrial wastes containing pentose or hexose or a mixture of both. 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.
