A method and architecture are provided for SOC (System on a Chip) devices for RAID processing, which is commonly referred as RAID-on-a-Chip (ROC). The architecture utilizes a shared memory structure as interconnect mechanism among hardware components, CPUs and software entities. The shared memory structure provides a common scratchpad buffer space for holding data that is processed by the various entities, provides interconnection for process / engine communications, and provides a queue for message passing using a common communication method that is agnostic to whether the engines are implemented in hardware or software. A plurality of hardware engines are supported as masters of the shared memory. The architectures provide superior throughput performance, flexibility in software / hardware co-design, scalability of both functionality and performance, and support a very simple abstracted parallel programming model for parallel processing.

A filesystem-aware storage system locates and analyzes host filesystem data structures in order to determine storage usage of the host filesystem. To this end, the storage system might locate an operating system partition, parse the operating system partion to locate its data structures, and parse the operating system data structures to locate the host filesystem data structures. The storage system manages data storage based on the storage usage of the host file system. The storage system can use the storage usage information to identify storage areas that are no longer being used by the host filesystem and reclaim those areas for additional data storage capacity. Also, the storage system can identify the types of data stored by the host filesystem and manage data storage based on the data types, such as selecting a storage layout and / or an encoding scheme for the data based on the data type.

A failure predicting unit predicts a failure in a hard disk device that forms a disk array. A data transferring unit transfers data from a failure-predicted hard disk device for which the failure is predicted by the failure predicting unit to a spare disk. A data deleting unit deletes the data from the failure-predicted hard disk device after the data transferring unit completes transferring the data.

A method and apparatus for dynamic quality adjustment based on changing streaming constraints is provided. According to one aspect of the present invention, a video stream is sent to a client according to a set of streaming constraints. At least a subset of the video information in the video stream is sent from a first source. Next, a signal is received indicating a relaxation of streaming constraints corresponding to the video stream. In one embodiment, the signal is a freeze frame signal. In another embodiment, the signal is a slow motion signal. In response to the signal, a set of improved quality video information from a second source is accessed and sent to the client. According to one embodiment, the set of improved quality video information comprises a still image. According to another embodiment, the set of improved quality video information comprises a set of preprocessed video information ready to be streamed. As a result of the techniques described herein, an improved quality visual image is available for presentation on the client and, consequently, when a viewer requests a presentation rate that reduces the streaming constraints on a video streaming service, the improved quality video information may be sent using the freed-up portion of the bandwidth previously allocated to the client.

This invention realizes an editing system and control method thereof capable of significantly improving working efficiency of editing work. A proxy editing terminal device creates an EDL with low-resolution video / audio data, resulting in reducing time to create the EDL. Further, the low-resolution video / audio data and high-resolution video / audio data having the same contents and different resolutions are previously stored, so that the creation of a final edit list with the high-resolution video / audio data based on the EDL can be started in a short time after the EDL is created with the low-resolution video / audio data. Thus working efficiency of the editing work can be significantly reduced with reducing time to create the EDL and the final edit list.

A dynamically expandable and contractible fault-tolerant storage system permits variously sized storage devices. Data is stored redundantly across one or more storage devices if possible. The layout of data across the one or more storage devices is automatically reconfigured as storage devices are added or removed in order to provide an appropriate level of redundancy for the data to the extent possible. A hash-based compression technique may be used to reduce storage consumption. Techniques for freeing unused storage blocks are also disclosed.

Load balancing of activities on physical disk storage devices is accomplished by monitoring reading and writing operations to logical volumes on the physical disk storage devices. A list of exchangeable pairs of logical volumes is developed based on size and function. Statistics accumulated over an interval are then used to obtain access activity values for each logical volume and each physical disk drive. A statistical analysis selects one logical volume pair. After testing to determine any adverse effect of making that change, the exchange is made to more evenly distribute the loading on individual physical disk storage devices.

And thus, even if the operator would not enter the control information, it can be easily set and the editing processing based on this control information can be conducted. And thereby, the video signal processing device having further improved usability can be realized.

Described embodiments provide a server for transferring data packets of streaming data sessions between devices. A redundant array of inexpensive disks (RAID) array having one or more stripe sector units (SSU) stores media files corresponding to the one or more data sessions. The RAID control module receives a request to perform the write operation to the RAID array beginning at a starting data storage address (DSA) and pads the data of the write operation if the amount of data is less than a full SSU of data, such that the padded data of the write operation is a full SSU of data. The RAID control module stores the full SSU of data beginning at a starting data storage address (DSA) that is aligned with a second SSU boundary, without performing a read-modify-write operation.

By selecting the VD index pictures displayed on the browser screen, display of the corresponding moving picture is started from a portion corresponding to the selected VD index picture.

A method for providing data regarding a storage system comprising storage devices is described herein. A storage management module of an operating system of the storage system may be used for servicing (e.g., monitoring or testing) storage devices according to servicing parameters. For each serviced storage device, a reporting module of the storage management module may collect storage device and storage system data upon the occurrence of predetermined events (e.g., when a storage device exhibits an error and monitoring begins, when monitoring ends, and when testing of the storage device ends). The collected data may be saved to a report file in a predetermined format and received by a program configured to automatically extract the data according to the predetermined format for use in storage device and storage system analysis and to determine modified servicing parameters used by the storage management module to service storage devices.

Various operating conditions may be defined based on available storage capacity and capacity to store data redundantly. One or more indicators may be used to represent the operating condition of the set of storage devices. The indicator(s) may be used to indicate whether additional storage capacity is recommended and, in a storage array, which slot in the array should be updated with additional storage capacity.

A method and apparatus for dynamic quality adjustment of digital media based on changing streaming constraints is provided. A digital media server sends a digital media stream according to a set of streaming constraints to a requesting client. Audio and visual information may be sent to a requesting client together in a single stream, or separately in multiple streams. A client sends a request over a control network to the digital media server indicating information of a particular type is no longer desired. In response to receiving the signal, the video server ceases transmission of that particular type of information to the signaling client, thus relaxing streaming constraints. As a result of the techniques described herein, an improved quality digital presentation is available for the client and, consequently, when a viewer signals that a particular type of information is not desired, that particular type of information is not transmitted to the client, which thereby reduces the streaming constraints on a video streaming service, and improved quality digital media information may be sent to any client using the freed-up portion of the bandwidth previously allocated to the signaling client.

A technique for read error failover processing in a mirrored disk system such as a Redundant Array of Inexpensive Disks (RAID) system, where individual disk units perform Logical Block Address (LBA) remapping. A read error causes a disk controller to report an “unrecoverable” read error to a RAID controller. After receiving this report of an unrecoverable read error, rather than simply switching over to a mirror, the RAID controller first checks to see whether the disk that caused the error can successfully reassign an LBA. In particular, the RAID controller can retrieve the data that was associated with the failed LBA from the mirror, and then write that data to the offending disk. The disk controller for that disk will then perform its standard LBA remapping, and write the data to a new, good sector. Only if this process does not succeed is the offending disk then treated by the RAID controller as having failed sufficiently to require failover to the mirror.

A recording system (75) includes a broadcast receiver (210) for receiving broadcast programmes, and a download receiver (280) for requesting and receiving content parts of a broadcast programme from a server (90). A controller (250) determines whether an instruction for recording a broadcast programme would exceed a capacity for recording and playback of programmes during at least part of the corresponding broadcast period. If so, the controller instructs a recorder (290) to record content parts of the broadcast programme during a part of the broadcast period in which the capacity is not exceeded and stores an identification of a content part of the broadcast programme that could not be recorded. It determines a period in which the capacity of the recorder is not exceeded and ensures that the not recorded content parts are downloaded from the server in the determined period and recorded.

A system that detects the onset of hard disk drive failure. During operation, the system measures vibrations from the hard disk drive to produce one or more vibration signals. Next, the system generates a vibration signature for the hard disk drive from the measured vibration signals. The system then determines if the vibration signature indicates the onset of hard disk failure by comparing the vibration signature with a reference vibration signature for the hard disk drive. If so, the system generates a warning or takes a remedial action.

An image processing system processes image data in response to a sequence of image processing steps defined by a process tree data structure. The process tree comprises a plurality of interconnected nodes, including input nodes and at least one output node. Output rendering is performed a frame at a time, and each frame is rendered in a time determined by the amount of processing defined by the process tree. The process tree may comprise many branches of interconnected nodes, and the user can selectively cache intermediately rendered frames at nodes where the contributing process tree branches are relatively stable in their configuration. The user may then make modifications to processes in other parts of the process tree, without having to wait for image data to be rendered from unchanged parts of the process tree.
