    摘要： A method and apparatus for recovering data from a failed disk drive in a disk drive array. The method and apparatus includes storing data on an array of disk drives by dividing extents (406) of data into data segments and defining a parity group (404) including at least one data segment from a plurality of data segments (402) from different extents. Parity segments (410) are generated from the data segments in the parity group and stored in the parity group. Furthermore, a second parity segment (408) is generated from the parity segments and stored with the parity group. The method and apparatus then outputs data in realtime to users in a normal disk access mode from parity groups without the failed disk drive, and outputs recovered data in realtime to users in a normal disk access mode from parity groups without the failed disk drive, and outputs recovered data in realtime to the users in a parity correction mode from the parity group containing the failed disk drive.

    摘要： An interactive information distribution system (100) includes service provider equipment for generating an information stream that is coupled to an information channel and transmitted to subscriber equipment (124). The service provider also generates a command signal that is coupled to a command channel and transmitted to the subscriber equipment (124). The service provider also receives information manipulation requests from the subscriber via a back channel (109). A communication network (110) supporting the information channel, command channel and back channel is coupled between the service provider equipment and the subscriber equipment (124).

    摘要： A method (200) and apparatus for masking the effects of latency within an information distribution system (100). The apparatus comprises a set top terminal (108) that requests and receives information from an information server (102). The information is generally displayed upon a conventional television (110) coupled to the set top terminal which contains a central processing unit (122) and an information stream decoder (130) programmed to implement the method. Upon execution of certain functions selected by a subscriber usually via a remote control (112), the method recalls (205) a predefined image from memory and begins to fade (206) the presently displayed image into a predefined image, e.g., a white screen. Simultaneously, the presently playing sound is also faded into the predefined sound, e.g., no sound. The decoder within the set top is reset (210). Lastly, the set top terminal fades (214) up from the predefined image to the new decoded video stream and from the predefined audio to the new audio stream.

    摘要： A method and apparatus for streaming content to an access network in an interactive information distribution system (100). The method initially encapsulates the content in accordance to an Internet Protocol (IP). In one embodiment, the content is configured as a plurality of a MPEG-2 packets contained in a payload of a Realtime Transport Protocol (RTP) packet (352 - 356) that is contained in an IP packet (300). The content is then transcoded into a format supported by the access network, and streamed over a distribution network to a remote server (201) or to a subscriber terminal that is coupled to the access network (104). The apparatus is embodied as at least one stream caching server (102) for streaming said content as an Internet Protocol (IP) packet to at least one access network via a stream distribution network in response to a request for content, where the content is encapsulated within the IP packet. A packet processor (144) is coupled to the at least one stream server for processing the encapsulated content within the IP packets into at least one packet in a format native to the at least one access network.
