Abstract: Efficient integrated digital video transcoding is described. In one aspect, an integrated transcoder receives an encoded bitstream. The integrated transcoder transcodes the encoded bitstream by partially decoding the encoded bitstream based on a first transform associated with a first media data format. The decoding operations generate an intermediate data stream. The integrated transcoder then encodes the intermediate data stream using a second transform associated with a second media data format. The first and second transforms are not the same.

Abstract: An improved dispensing closure system (30, 230, 330, 430, 530, 630) for dispensing a product from a container includes an elongate or oblong dispensing orifice (52, 252, 552) for dispensing a ribbon of product. The dispensing closure system also includes a spout having a dispensing orifice (52) that is oriented at an angle relative to the closure deck (35) and relative to the flow direction of product from the orifice (52). The closure system (30, 230, 330, 430, 530, 630) provides fo an abrupt 'cut-off of product and thus provides for the dispensing of product in a clean and controlled manner without mess. The closure system (30, 230, 330, 430, 530, 630) also incorporates conical geometries in transition surfaces (51, 57; 251, 257; 351, 357; 451, 457; 551, 557; 651 657) extending from the container opening to the dispensing orifice.  The conical geometries of the transition surfaces provides for a smooth transition of product flow from the container opening to the dispensing orifice, while minimizing the volume defined by the closure system spout and thereby providing increased 'suck-back' and an abrupt 'cut-off of product compared to prior art devices.
