Patent CA-2263770-A1 (CA)
Title: Moving image encoding apparatus and moving image decoding apparatus
Inventor: KUSAO HIROSHI
IPC: H04N19/59
Filed: 1997-05-16
Abstract: When a background interpolation-judging section judges that parts areas of a lower layer and an upper layer move significantly, and a visual effect can be obtained by the background interpolation, a controller controls a switch based on the area information of the parts area of the lower layer to perform the background interpolation. A weighted average section takes an average by weighting the upper layer and the lower layer by using the interpolated background to generate an interpolated image. By using this interpolated image, the prediction-encoding/decoding of the upper layer is performed. On the contrary, when the background interpolation-judging section judges that parts areas do not move significantly, and a visual effect cannot be obtained by the background interpolation, a background is synthesized by using the output of the interpolated image-forming section to generate an interpolated image.      Hence, the shape information for the background interpolation is reduced and a high quality image can be obtained.
Patent CA-2265313-A1 (CA)
Inventor: EDMON EUGENE L
IPC: H04N7/173
Filed: 1999-03-15
Abstract: A protocol for handling multiple access on broadband communication networks, e.g., fiber/coax networks and wireless networks, supports both continuous bit rate (CBR) and variable bit rate (VBR) traffic representing voice, video telephony, interactive television, and data. The invention is carried out both in customer premise equipment (CPE) at stations, and in a common controller with which all stations communicate. A medium access control (MAC) processor provided in each of the stations and in the common controller divides the time domain for a given RF channel into a series of successive frames, each having a plurality of time slots. Because of the architecture of the communication network, individual stations do not communicate directly with each other, but can receive broadcast messages indicating the status of each time slot, which messages are generated in the common controller and transmitted in a downstream channel. When a station desires to transmit information in the upstream direction, it inserts the information into an 'available' time slot, with availability being determined in accordance with time slot status. Depending upon the type of traffic being originated, a station can indicate to the common controller a need for continued use of the "same" time slot in successive frames. This permits a station, such as a station requiring a CBR connection, to avoid having to contend repeatedly for continued access to the transmission network. In the case of a wireless communication network, the invention is carried out both in mobile stations, and in a base station which acts as a common controller and with which all mobile stations communicate.
