Patent CA-2328458-A1 (CA)
Title: Method and apparatus for providing guaranteed quality of service in a local or wide area network
Inventor: GOLDEN MICHAEL E
IPC: H04L45/42
Filed: 1999-04-09
Abstract: A method and apparatus for adapting existing packet-switched LAN infrastructures (e.g. packet-switched Ethernet) so as to be able to provide reserved-bandwidth virtual-circuit switching services in addition to their conventional capabilities. A centralized control point is incorporated within the infrastructure, preferably via a firmware upgrade to an existing enterprise-class switch, that maintains a map of paths between endstations in the network, as well as the bandwidth capabilities of all links and switches along the paths. When a virtual circuit connection between endstations is requested, the centralized control point determines whether the requested bandwidth is available all along the path. If so, the resources along the path are reserved for the connection. Existing switches in the LAN infrastructure are adapted to give priority to packets belonging to the connection, thereby providing the desired QoS for that connection.

Title: Sifting net for a fibre distributor
Inventor: ANDERSEN JENS OLE BROCHNER
IPC: D21H27/00
Filed: 1999-04-20
Abstract: A fibre distributor (1) forms an air-laid fibre web (17) on a running endless forming wire (2) which, during operation, in principle is horizontal. The fibre distributor comprises a suction unit (14) positioned under the forming wire, a housing (3) positioned above the forming wire and having at least one combined fibre and air inlet (4), and a base (6) having a number of flow openings (7), and a number of rotational wings (10) positioned above this base. These wings distribute the fibres along the upper side of the base. The base is designed as a grid (18) with grid bars (19) which taper in a downwards direction. In the flow openings (20) of the grid, a slip is advantageously formed which prevents the fibres from packing together and blocking the openings during operation. The fibre distributor is thus, at a continuous high capacity, able to form an even and homogenous fibre layer on the forming wire.

Title: Logo insertion on an hdtv encoder
Inventor: WU SIU-WAI
IPC: H04N7/26
Filed: 2001-01-05
Abstract: An encoder and encoding method for inserting logos into a digital television signal. The logo insertion is performed at the front end of the encoder (e. g., prior to compression) by sharing the video capture frame buffer of the encoder, so there is no need for a separate logo inserter with a separate buffer, and encoding costs are reduced. An alpha blending function receives logo image and logo alpha map data for blending with input video data. The input video is retrieved from the frame buffer, and written back to the frame buffer after blending with the logo data.      Subsequently, the frame buffer contents are provided to a pre-processing function for filtering and film mode detection. For a film mode frame, a drop field decision is provided from the pre-processing function to the frame buffer to drop the redundant field. The pre-processed video data is then provided for conventional compression processing. In an HDTV embodiment, several compressors are provided which each receive a panel of a video frame.
