Title: Rate control for an MPEG transcoder without a priori knowledge of picture type
Inventor: WANG LIMIN
IPC: H04N7/26
Filed: 1999-10-08
Granted: 2001-08-11
Abstract: A rate control system suitable for use with a digital video transcoder, such as one conforming to the MPEG standard. The proposed rate control system starts coding with any reasonable set of assumed Group of Pictures (GOP) parameters, thereby avoiding a processing delay of about one GOP which would otherwise be incurred to extract the complete GOP structure information from a pre-compressed bit stream. In addition, the system avoids the need to store the data corresponding to the GOP, thereby reducing the memory required for transcoding. Encoding of a first picture in a sequence or GOP begins without a priori knowledge of the picture type of subsequent pictures. A reasonable set of GOP parameters is assumed to determine an encoding bit budget. The bit budget is gradually corrected as successive pictures are coded according to their picture types. Changes in the GOP structure of pre-compressed bitstreams can be addressed, for example, when switching channels, inserting commercials, and the like. Target rates with incorrect starting GOP parameters will converge within a few GOPs.

Granted: 2001-12-21
Abstract: A field effect transistor is made on a chip (20) comprising a SiC-substrate. The transistor includes a plurality of densely stacked parallel transistor cells occupying totally a rectangular area (21). Each transistor cell has parallel strip-shaped regions forming the electrodes and active areas of the cell and each inner cell shares its drain and sources electrodes with neighbouring cells. In order to give a good power dissipation allowing an electrical high power of the transistor, the rectangular area has a very elongated shape and specifically it should have a width not larger than substantially 50 μm. In the rectangular area all the transistor cells have their strip-shaped regions located in parallel to short sides of the rectangular area and are generally very short considering the length of the rectangular area. Thus specifically also each cell has a length not larger than substantially 50 μm. The distances from the long sides of the rectangular area to the edges of the chip should be at least 50% and preferably 60% of the thickness of the chip to allow a good thermal flow out of the active rectangular area. A plurality of such very elongated active areas can be located on a single chip.
