Patent number: 6647061Abstract: A transcoder architecture that provides the lowest possible complexity with a small error, e.g., for converting an MPEG-2 bitstream into an MPEG-4 bitstream. The transcoder reads header information from an input bitstream and provides a corresponding header in the new format for the output bitstream. In one embodiment, a low complexity front-to-back transcoder (with B frames disabled) avoids the need for motion compensation processing. In another embodiment, a transcoder architecture that minimizes drift error (with B frames enabled) is provided. In another embodiment, a size transcoder (with B frames enabled) is provided, e.g., to convert a bitstream of ITU-R 601 interlaced video coding with MPEG-2 MP@ML into a simple profile MPEG-4 bitstream which contains SIF progressive video suitable for a streaming video application. For spatial downscaling of field-mode DCT blocks, vertical and horizontal downscaling techniques are combined to use sparse matrixes to reduce computations.Type: GrantFiled: June 9, 2000Date of Patent: November 11, 2003Assignee: General Instrument CorporationInventors: Krit Panusopone, Xuemin Chen

Patent number: 6643707Abstract: The Domain Name System (DNS), which has been used for mapping names to Internet Protocol (IP) addresses, is adapted to a broadcast environment, such as a broadband cable or satellite television network. A number of master files are stored on a broadcast name server that define zones of domains in a domain name space, which may include a television-related domain, with sub-domains for different service providers (e.g., ABC, HBO), and a cable domain, with sub-domains for applications, administrative functions and operating system-functions, e.g., at a set-top terminal. The television sub-domains may have their own sub-domains. For example, “ABC” may have the sub-domains “NEWS”, “WEATHER”, and “SPORTS.” The master files are used to form broadcast resource records, which include an identifier for broadcast services (e.g., “ABC”) or other data sources, and which are transmitted to end user terminal devices periodically, or in response to a query.Type: GrantFiled: February 14, 2000Date of Patent: November 4, 2003Assignee: General Instrument CorporationInventor: Robert C.

Patent number: 6643327Abstract: A system for rate control during transcoding and encoding of digital video data in a multi-program transmission environment accommodates changes in the GOP structure of any of the programs, e.g., due to a commercial insertion or the like. A hierarchical bit allocation scheme is used, where bits are allocated on a super group of pictures (GOP) level, i.e., a grouping of multiple GOPs, a super frame level, and an individual frame level. The bit allocation for the super GOP and each picture is adjusted when a change in the structure of a group of pictures (GOP) is detected for any of the pre-compressed programs. The super GOP length may also be adjusted if required to maintain an integer number of GOPs therein. A change in the GOP structure is detected based on a change in the GOP length or sub_GOP length (distance between P pictures). For pre-compressed data, initial GOP lengths and sub_GOP lengths can be assumed and adjusted as required based on actual measurements.Type: GrantFiled: May 5, 2000Date of Patent: November 4, 2003Assignee: General Instrument CorporationInventor: Limin Wang

Patent number: 6622944Abstract: A two phase fuel oil atomizer utilizing a secondary media such as high pressure steam or air to assist in the atomization of heavy fuel oil, while reducing NOx and other polluting emissions. The fuel oil atomizer comprises a mixing plate and a sprayer plate which are configured to discharge atomized fuel oil at varying spray angles in order to provide staging of the atomized fuel as it exits the sprayer plate with the surrounding combustion chamber air to provide a fuel/air ratio that is appropriately rich and lean in order to allow lower flame temperatures. NOx generation is accordingly reduced at the lower flame temperatures. With atomized fuel droplet size small enough to enable rapid fuel evaporation and complete combustion, low CO, opacity and particulate generation are achieved with minimum excess oxygen.Type: GrantFiled: April 20, 2001Date of Patent: September 23, 2003Assignee: Combustion Components Associates, Inc.Inventors: John F.
