    摘要： A method and apparatus for reconstructing lost data from a failed disk drive in a disk array. The disk drive array formed into at least one parity group including data extents divided into data segments and parity segments that are generated from the data segments. The method includes providing access to the array, identifying a failed drive and failed parity group associated with the failed drive, and retrieving the parity segments from operative drives in a parity group containing the failed drive in an instance data is being read from the failed parity group. Parity information is reconstructed for the failed disk drive from the parity segments on the operative disk drives, and data segments of the extent associated with the failed disk drive is reconstructed from the reconstructed parity information, and the parity segments and data segments on the operative disk drives of the failed parity group.

    摘要： An interactive program guide (IPG) may include a program grid section and a multimedia section. The program grid section typically contains program information organized in a grid with a time axis and a channel axis. The multimedia section may include video for advertisement, previews, and other purposes. Such an IPG may be rendered and encoded at a server and distributed to client terminals in the form of compressed bit streams.For certain IPGs, the program grid section may comprise alternating stripes of background with different shades (lighter/darker) or different colors. Typically, the alternating background stripes may be used to visually separate text information into timeslots or channels.Blank areas of the background may be “skip” encoded to “save” a portion of the bit rate. Meanwhile, the quantizer stepsize for encoding that section may be lowered so as to utilize the saved bits to improve the viewing quality of the program grid section. Additionally or alternatively, the quantization matrix for encoding the program grid section may be optimized for encoding text (rather than being, for example, a standard quantization matrix).Encoding may be performed on the program grid section such that encoded macroblocks do not cross a border between two stripes. In other words, each encoded macroblock in the program grid section may be within a single stripe. Additionally or alternatively, low-pass frequency filtering may be applied on the background stripes. Such low-pass filtering reduces visual defects due to ringing from edges between stripes.

    摘要： A method for transmitting data to a receiver comprises the steps of transmitting a pre-conditioning signal to the receiver, and beginning to transmit at least one data packet to the receiver within a given period after beginning transmission of the pre-conditioning signal. The preconditioning signal is separate from a leader of the data packet to be transmitted.

    摘要： A method and system are provided for identifying a current user of a terminal device from a group of possible users. The method includes providing a database containing multiple user input pattern profiles of prior user inputs to the terminal device. Each of the possible users of the group are associated with at least one of the user input pattern profiles. Current input patterns from use of the terminal device are detected. The current input patterns are combined and then dynamically matched with one of the user input pattern profiles, and the possible user associated with the matched user input pattern profile is selected as the current user.
