Patent CA-2392546-C (CA)
Title: Video transmission of multiple program signals with encoded bit rates determined by program complexity
Inventor: AZMOODEH MASOOMEH
IPC: H04N7/24
Filed: 2000-11-27
Granted: 2008-04-08
Abstract: The invention concerns the control of Asynchronous Transfer Mode (ATM), or other systems, using available bit rate (ABR) transmission. A source of data is permitted to transmit at a data rate which is set by the network according to the available capacity. Where television pictures are being transmitted, the actual data rate can be controlled by varying the degree of compression applied by video coder (or transcoder). Existing procedures for dividing up the available capacity between competing video sources are found to be unsatisfactory in terms of achieving equal picture quality for each source. In the invention, each source calculates a measure of picture complexity, and the network (for example, an ATM switch) uses the means to calculate how the capacity should be shared.

Abstract: A seat device includes a safety bar which is connected to two lateral wing members of a seat body by insertion of two insert plugs into two mounting sockets, respectively. A lever plate is pivoted to each socket and is turnable such that an engaging end thereof engages a concavity in the corresponding plug to place the safety bar in an engaged state. Pressing an opposite actuating end of the lever plate will cause the engaging end to disengage from the concavity so as to permit removal of the plug from the socket.

Abstract: In a plasma film forming apparatus, two first electrodes 51 connected to a power source 4 and two grounded second electrodes 52 are arranged in the order of the second electrode 52, the first electrode 51, the first electrode 51 and the second electrode 52. A first flow passage 50a formed between the central first electrodes 51 allows a raw material gas (first gas) for being formed into a film to pass therethrough. A plasma discharge space 50b of a second flow passage formed between the first and second electrodes 51, 52 on the both sides allows an excitable gas (second gas) to pass therethrough, which excitable gas is exited by plasma such that the raw material can be formed into a film, but that the excitable gas itself is merely excited but not formed into a film. Those gases are converged at a crossing part 20c between the first and second flow passages and blown off via a common blowoff passage 25a. By this, the apparatus composing members such as electrodes can be prevented from being adhered with a film.
