Abstract: A method and system for cache-based dropped write protection in data storage systems are provided. An implementation involves detecting undetected write errors in a storage system, by writing data to a storage medium from a data cache; maintaining a copy of the data in the data cache until said data on the storage medium is validated or said data needs to be evicted from the data cache; and prior to eviction of said data from the data cache, maintaining metadata for said data in a metadata cache until the data written to the storage medium has been validated against the metadata.

Abstract: The present invention provides a method and a system for generating a block acknowledgment for aggregated MSDUs (A-MSDU) transmitted from a sender to a receiver over a wireless channel. Upon receiving the A-MSDU, the receiver generates a MSDU Block Acknowledgment (MSDU-BA) that includes an acknowledgment for each received MSDU. Based on the MSDU-BA, the sender selectively retransmits only the erroneous MSDU(s) to the receiver.

Abstract: A method and corresponding systems for using remote control to realize standard colors on displays. Two examples of remote controls are provided, one with color sensors and the other with white LEDs. For each example a calibration pattern is displayed which allows a user to calibrate the display color conveniently. For using the remote control with color sensors, an algorithm for the display to adjust the input RGB color, based on the color measurements from the remote control is provided. This allows the display output RGB color so that the display shows the same color as the input RGB signal is sent to standard color display.

Abstract: A retransmission method and system for time-constrained video packet transmission between a sender and a receiver, wherein the retransmission deadline of each packet is individually adjusted based on the actual decoding time deadline at the receiver decoder. Accordingly, variable retransmission deadlines are set corresponding to the decoding and playback time for each data packet which carries compressed video information. As such, both network efficiency and video transmission quality are improved compared to the conventional retransmission approaches.

Abstract: The present invention provides a method and a system for PSMP communication in a wireless communication system such as an IEEE 802.11n WLAN including an AP and multiple STAs. An example of such a PSMP communication involves transmitting a PSMP frame from the AP to the STAs over a wireless channel, detecting if the channel is idle for certain duration, and if the channel is idle for said certain duration, then performing a PSMP recovery process. The PSMP frame includes one or more STA info fields which specify schedules of periods for communication over the wireless channel in a PSMP sequence. In performing a PSMP recovery process, the AP constructs and broadcasts a PSMP recovery frame that allows STAs that missed the original PSMP frame to join the PSMP sequence.

Abstract: A video quality adaptive coding artifact reduction system has a video quality analyzer, an artifact reducer, and a filter strength controller. The video quality analyzer employs input video quality analysis to control artifact reduction. The video quality analyzer accesses the video quality of the decoded video sequence to estimate the input video quality. The filter strength controller globally controls the filter strength of the artifact reducer based on the video quality estimate by the video quality analyzer. For low quality input video, the filter strength controller increases the artifact reduction filter strength to more efficiently reduce the artifact. For high quality input video, the filter strength controller decreases the artifact reduction filter strength to avoid blurring image detail.

Abstract: A method and system for presenting TV channels to a viewer is provided. One or more channel lists are generated based on selection criteria. The channel shuffle scanning is performed by presenting per channel content to a viewer from a channel list, for user viewing within a pre-selected period of time until the viewer picks a channel.
