    摘要: A method, system and computer software product for managing jitter buffering that accurately measures network latency, the variation in latency (also known as jitter), and efficiently manages the media packet stream and jitter buffers is disclosed. A framer time-stamps incoming packets. A traffic analyzer maintains a sliding window of statistics generated from a recent set of packets. A jitter manager monitors packets, receives and makes adjustments based on information received from the traffic analyzer, and manages any connected jitter buffers.

    摘要: An apparatus and technique are disclosed for controlling the resource usage of a processor during a video conference by dynamically varying the rate at which video images are compressed so as to maintain a target threshold of processor resource usage. A control program module interfaces with the video encoder of a video conferencing system and first checks that the current processor resource utilization is below a specified target threshold prior to compressing a video image from a stream of captured video data. If the processor resource utilization is below the target threshold, the video image is compressed. Otherwise, the image is skipped to conserve processor resources. The technique allows video conferencing products to dynamically adjust the rate of video frame compression based on available processor resources so as to maximize the user's video conferencing experiencing while minimizing the negative impact on other applications executing on the system.

    摘要: In connection with the play of conventional keno games, both live keno games and mechanical or electronic keno gaming machines, the player is provided with the opportunity to win a "bad beat" bonus payout. The player uses a single keno ticket, and may be required to make an optional side bet wager to be eligible for the "bad beat" bonus payout or the player may be eligible simply by participating in the conventional keno game. If the player is "jackpot qualified" and the player plays at least five consecutive games of keno using the same keno ticket, the player wins a special payout.

    摘要: A device and method for detecting a containment failure. The device has a gas supply means (18) for providing a gas to a containment failure volume (16, 60) and for maintaining a constant gas pressure in the containment failure volume. The device also has gas flow monitoring means (26) for monitoring flow of the gas into the containment failure volume. The flow of gas into the containment failure volume is indicative of a containment failure.
