20120039393 | Video decoding apparatus and method - A video decoding apparatus for decoding an encoded video bitstream having frames of video data encoded in rows of macroblocks. The video decoding apparatus comprises a parsing unit configured to receive the encoded video bitstream and to interpret the encoded video bitstream to generate items of macroblock information to be used for reconstructing the video frames of video data. The parsing unit is configured to store the items of macroblock information in a memory in bitstream order. The video decoding apparatus further comprises a line control unit configured to generate line control information associated with each row of macroblocks, the line control information comprising a sequence of pointers to the items of macroblock information stored in the memory, such that sequentially reading the sequence of pointers accesses the items of macroblock information in raster scan order. The line control information is stored in said memory in association with said items of macroblock information. A reconstruction pipeline is configured to reconstruct the frames of video data with reference to the line control information. | 02-16-2012 |
20130022128 | Video decoder with a programmable inverse transform unit - A data processing apparatus is provided for performing video decoding operations on blocks of video data, the data processing apparatus comprising: a programmable inverse transform unit configured to perform an inverse transform operation on a set of input values in response to a sequence of instructions, the programmable inverse transform unit comprising a first execution path and a second execution path arranged to perform data operations to implement the inverse transform operation, wherein the data operations performed by the first and second execution path are configured in dependence on the sequence of instructions, wherein the programmable inverse transform unit is configured to operate in a first mode in which each instruction in the sequence of instructions is interpreted using a first instruction length and causes the first execution path and the second execution path to be configured independently of each other, and the programmable inverse transform unit is configured to operate in a second mode in which each instruction in the sequence of instructions is interpreted using a second instruction length, the second instruction length being shorter than the first instruction length, and causes the second execution path to be configured in dependence on a configuration of the first execution path. | 01-24-2013 |

20100122044 | Data dependency scoreboarding - A parallel processing technique is described for performing parallel processing operations upon N-dimensional arrays of data elements for which a corresponding N-dimensional Scoreboard of status data is held. Hazard checking for data dependencies upon data elements within the N-dimensional array of data elements is performed by looking up the corresponding status value within the Scoreboard. The status data for a given data element within the Scoreboard is located at a position which can be derived from the position of the data elements within its N-dimensional array. Thus, a two-dimensional array of video macroblocks can have a corresponding two-dimensional Scoreboard of status data indicating whether individual macroblocks have, for example, either already been deblocked or have not already been deblocked. | 05-13-2010 |

20100263745 | DRAIN PLUG - A drain plug for controlling the flow of a liquid through a drain hole. The drain plug has a drain plug body with a drain passage extending partly through the drain plug body. The drain passage has at least one outlet port. The drain plug has a check valve for allowing the flow of the liquid through the drain passage in a first direction and substantially inhibiting the flow of liquid through the drain passage in a second opposite direction. The drain plug is moveable relative to a drain hole between at least one open position in which the at least one outlet port is exposed or open and liquid may flow through the passage and at least one closed position in which the at least one outlet port is covered or closed by the drain hole housing to substantially inhibit liquid flowing through the passage. | 10-21-2010 |

20090130729 | Biocatalytic manufacturing of (meth) acrylic esters - The invention relates to a biocatalytic method or process for the synthesis of esters of acrylic acid and/or methacrylic acid free of positively chargeable/charged groups, comprising reacting one or more alcohols (alcohol starting materials) which are free of positively chargeable or charged groups with (meth)acrylyl-CoA, preferably in the presence of a catalyst (inorganic, organic or organometallic, or preferably a biocatalyst) capable of effecting the transfer of an alcohol radical from an alcohol starting material as defined above or below to (meth)acrylyl CoA under removal of the CoA moiety transferase activity, such as an enzyme of the transferase or hydrolase class of enzymes. The (meth)acrylyl-CoA is preferably formed by reaction of (meth)acrylic acid or its salts with coenzyme A in the presence of an energy providing substance and a biocatalyst e.g. with S-acetyl coenzyme A synthetase activity or by reaction of acrylate or methacrylate produced metabolically in the presence of a biocatalyst or metabolically. | 05-21-2009 |

20130272092 | IDENTIFICATION, DETECTION AND POSITIONING OF UNDERWATER ACOUSTIC REFLECTORS - A method of identifying and locating an acoustic reflector is described by interrogating underwater objects with a sonar and deploying one or more of the steps of a. identifying objects that apparently reflect the acoustic interrogation with a double echo, measuring the separation of the two echoes and comparing those measurements with anticipated measurements for underwater acoustic reflectors that may be present in the search area, and accepting or rejecting the reflected acoustic wave as potentially including the echo from the front of such an acoustic reflector and the echo from the shell at the rear of the reflector; b. measuring the target strength of the echoes in a double echo received from an object and rejecting the object as one of interest if the target strength in the first echo of a double echo exceeds that of the second echo; c. measuring the total target strength of an echo from an object, the object being rejected as being a potential underwater acoustic reflector of interest if the target strength is less than a predetermined minimum; d. measuring the acoustic width of an object and comparing that with the acoustic width of known acoustic reflectors, the object being rejected as being potentially an underwater acoustic reflector of interest if the acoustic width is not that of a known underwater acoustic reflector; e. measuring the frequency response of an object, the object being accepted or rejected as being potentially an acoustic reflector of interest if the frequency response corresponds to the known frequency response of such an underwater reflector; and f. measuring the phase response of an object, the object being accepted or rejected as potentially an underwater acoustic reflector of interest if the phase response corresponds to the known phase response of such an underwater acoustic reflector. The target is being rejected as being an acoustic reflector of interest if the measured characteristics do not match the known characteristics of a reflector of interest. | 10-17-2013 |
