Original-quality MPEG coded video is processed to produce reduced-quality MPEG coded video for trick mode operation by removing non-zero AC DCT coefficients from the 8×8 blocks of I-frames of the MPEG coded video to produce I-frames of reduced-quality MPEG coded video, and inserting freeze frames in the reduced-quality MPEG coded video. Preferably, the coded video is stored in a main file, a fast-forward file and a fast-reverse file. The fast forward file and the fast reverse files contain reduced-quality I frames corresponding to original-quality I frames in the main file. A reading of the main file produces an MPEG transport stream for an audio-visual presentation at a normal rate, a reading of the fast-forward file produces an MPEG transport stream of the audio-visual presentation in a forward direction at a fast rate, and a reading of the fast-reverse file produces an MPEG transport stream of the audio-visual presentation in a reverse direction at a fast rate. Preferably, the files share a volume that includes at least one GOP index associating the corresponding I frames of the files.

Rate charging rules and principles concerning mobile calls in a cellular communication system can be improved by providing the mobile station with a locator object which, at certain intervals, determines the cell in which the mobile station is currently located. Stored in the mobile station is a list of cells or areas in which a special rate is to be applied in charging for calls originating from the mobile station. The locator object monitors calls made from the mobile station and, when it detects that a call is being made, it determines whether the mobile station was in a denoted special rate area at the time that its location was most recently determined. If so, then the object informs the network that the call is entitled to the special rate. Since the last location function was executed just before call setup commenced, a special rate call is possible even if the mobile station has thereafter moved some distance into a cell applying a normal rate. Disposed in a billing center is a billing object, to which the locator object sends data indicating whether the call was initiated from a cell or area in which a special rate is applicable, as well as data identifying the particular call. The second object receives the billing records generated by the mobile switching center, which also contain call identifying data, and compares the call-specific data in those records with the data sent by the first object. In this way, the second object can identify from the billing records those calls that are entitled to a special rate, regardless of whether the mobile station has moved during call setup from the original cell into a cell where another rate, e.g. a higher rate, is applicable.

A close-talk detector detects a near-end user's speech signal, while an adaptive ANC process is running, and in response helps prevent the filter coefficients of an adaptive filter of the ANC process from being corrupted, thereby reducing the risk of the adaptive filters diverge. Upon detecting speech using a vibration sensor signal and one or more microphone signals, the detector asserts a signal that slows down, or even freezes or halts, the adaptation of the adaptive filter. The signal may be de-asserted when no more speech is being detected, thereby allowing the adaptive ANC process to resume its normal rate adaptation of the filter. The detector may continuously operate in this manner during the call, as the user talks and then pauses and then resumes talking. Other embodiments are also described.

A DRAM memory device includes several banks of memory cells each of which are divided into first and second sets of memory cells. The memory cells in the first set can be refreshed at a relatively slow rate to reduce the power consumed by the DRAM device. Error checking and correcting circuitry in the DRAM device corrects any data retention errors in the first set of memory cells caused by the relatively slow refresh rate. The memory cells in the second set are refreshed at a normal rate, which is fast enough that data retention errors do not occur. A mode register in the DRAM device may be programmed to select the size of the second set of memory cells.

A method and system is provided to enable quality of service across a backplane switch. An egress queue manager on one blade communicates with an egress queue manager on another blade where each blade is connected via a backplane switch. When a blade becomes congested, egress queues mapped to a destination on the congested blade also become congested. The egress queue managers determine when to reduce or resume the packet sending rates of egress queues mapped to destinations on congested blades using a messaging scheme. Each egress queue manager maintains notifications of the status of egress queue congestion on its own and other blades. Normal rates of dequeuing packets are resumed only when the related congestion on all of the blades has subsided.

According to the video buffer method, a network speed environment can be automatically sensed, and a buffer length and a play rate can be automatically regulated according to the network speed environment, so that the adaptive bandwidth play of a final user of the video service system in different network speed environments can be effectively realized; and in addition, high video play continuity is ensured, so that the service can obtain highly-satisfactory network streaming media service in different network environments.

Segments of a recorded video program that are classified to be skipped during replay are scanned through at a predetermined rate, which is independent of viewer control. While faster than the normal play mode, the rate of forward scan is such that the content of the video segments being skipped can still be readily perceived. While in this controlled forward scan mode, viewer control of the scanning rate may be disabled. A viewer-controlled input may be provided so that a portion of a video segment being skipped can be viewed at a normal rate of play starting at the beginning of the portion that the viewer wishes to see. Once that portion of the video segment has been played at normal speed, the video playback device automatically switches to a predetermined mode of operation. Segments of a recorded video signal may be automatically rearranged for playback, allowing for all segments of one type to be played back contiguously, followed by playback of all segments of a second type.

A method and system is provided to enable quality of service across a backplane switch. An egress queue manager on one blade communicates with an ingress queue manager on the same or on another blade where each blade is connected via a backplane switch. The egress queue managers communicate the congestion to ingress queue managers using a messaging scheme. The ingress queue managers determine when to reduce or resume the packet sending rates of ingress queues mapped to congested egress queues or to destinations on congested blades. Each ingress queue manager maintains information about the status of egress queue congestion on its own blades. Normal rates of dequeuing packets from ingress queues are resumed only when the related congestion on all of the egress queues or related destinations has subsided.

An emergency lubrication system for a turbine engine includes a reservoir 50 containing a reserve quantity of lubricant 52 and having a lubricant inlet 54 and a lubricant outlet 56. A lubricant supply line 62 and a lubricant outlet line 66 each have a respective valves 64, 68 for regulating lubricant flow into and out of the reservoir. A fluid supply line 70 includes a valve 72 for selectively establishing communication between the reserve quantity of lubricant and a source of pressurized fluid. During normal operation the lubricant outlet valve continuously releases lubricant at a normal rate to the component requiring lubrication while the lubricant inlet valve concurrently admits fresh lubricant into the reservoir. During abnormal operation, the lubricant inlet valve closes in response to abnormally low lubricant pressure outside the reservoir thereby preventing backflow of reserve lubricant out of the reservoir. The fluid inlet valve opens to admit pressurized fluid into the reservoir thus pressurizing the reserve lubricant. The lubricant outlet valve opens or cycles open and closed in response to a command from a controller 26 so that the pressurized fluid forces lubricant through the outlet 56 as a subnormal rate, which persists until the lubricant reserve is substantially depleted. The subnormal rate is ideally achieved by intermittently releasing lubricant from the reservoir, but may also be achieved by releasing a continuous stream of lubricant at a rate less than the normal rate of release.
