IMAGE PROCESSING

Data is transferred over a network having many image data processing systems (101, 102). A high bandwidth network (121) is connected to each of the data processing systems and to each of several storage systems (111, 112). Each of the storage systems is operated under the direct control of one of the processing systems. A request is issued from a first processing system to access a data storage system controlled by a second processing system over a low bandwidth network (151). A bandwidth assessment process assesses an extent to which the second processing system requires access to its local storage system. The first processing system is given access to the second storage system if an assessment is made to the effect that local access requirements are identified as being below a predetermined threshold.

MODULAR STORAGE SERVER ARCHITECTURE WITH DYNAMIC DATA MANAGEMENT

The architecture of the present invention employs dynamic data management methods, which determine whether data should reside on disk or secondary storage (130), on which disk drives data should be stored, and how data should be replicated and/or migrated to new disk drives based on observed user (120) access patterns. These methods also migrate popular data to faster disk tracks to reduce average access time and thus improve performance. User access requests are assigned to modules based on the data stored at each module, and each module's current load (the number of request: waiting to be serviced). If the requested data is not on a disk drived, the data is retrieved from secondary storage (130), and may be stored on the disk drives for rapid subsequent access. When a requested data item on the disk drive is replicated, load balancing is perfomred by assigning the request to the module holding the data with the lowest load. In addition, user access requests waiting to retrieve replicated ...

CORRELATION OF MEDIA METADATA GATHERED FROM DIVERSE SOURCES

A DVR, server, or other agent correlates media metadata from diverse sources, like an EPG data provider and multiple video-on-demand (VOD) service providers. Metadata sets from different sources are compared in order to attempt to identify identical programs to which the metadata sets pertain. From at least one metadata set, information about the program that the other metadata set lacks is selected. A "canonical" data structure instance for the program is created. The information that is lacking from at least one of the metadata sources is inserted into that instance. For each source from which a program is available, the DVR stores the identity of that source on the DVR's persistent storage device in association with the canonical data structure instance for that program. The DVR receives search criteria from a user and then searches the stored canonical data structure instance for programs that satisfy the criteria.

Metadata enabled push-pull model for efficient low-latency video-content distribution over a network

Partitioning streaming media files on multiple content distribution networks

Techniques are disclosed for generating preference rankings in response to requests for streaming media content received from client devices. The preference rankings are used to indirectly partition streaming media content across different content distribution networks (CDNs). Such partitions may be referred to as a "soft" partition, as all of the streaming media content remains available from each CDN. That is, the partitioning of content across CDNs is not absolute, and any content item may be requested from any CDN. Doing so ensures that content remains available even where the preferred CDN for a given content item fails, while at the same time increasing the probability of a cache hit at the CDNs, without increasing the cost or the actual cache sizes of the content caches of different CDNs.

Computer system and process for transferring multiple high bandwidth streams of data between multiple storage units and multiple applications in a scalable and reliable manner

Multiple applications request data from multiple storage units over a computer network. The data is divided into segments and each segment is distributed randomly on one of several storage units, independent of the storage units on which other segments of the media data are stored. At least one additional copy of each segment also is distributed randomly over the storage units, such that each segment is stored on at least two storage units. This random distribution of multiple copies of segments of data improves both scalability and reliability. When an application requests a selected segment of data, the request is processed by the storage unit with the shortest queue of requests. Random fluctuations in the load applied by multiple applications on multiple storage units are balanced nearly equally over all of the storage units. This combination of techniques results in a system which can transfer multiple, independent high-bandwidth streams of data in a scalable manner in both directions between multiple applications and multiple storage units.

Direct copying between disk blocks in memory onto a network as sequential access files

In the multimedia network, in order to archive or play multimedia data for a production, a multitude of disk file blocks are retrieved from a multitude of files striped across a multitude of disk storage systems through a commutator to the input of an input/output unit. The disk file blocks are copied from the input into disk file blocks in a buffer of the memory of the unit. Then the unit creates a address-size list of data portions in the buffer for archiving the disk files of the production or for playing a multimedia data stream for the production. Then the unit executes a copy command given the address of the list which uses indirection for copying the specified portions of the buffer onto an output of the unit to store the data into an archival tape storage system or to play the production in a multimedia data stream. Also, using the above method, a production may be simultaneously archived and played by the same unit. In a related process, in order to restore the archived production or to record a multimedia data stream, the unit creates an address-size list for copying data from an input of the unit into portions of disk file blocks in a buffer in the memory of the unit. Then the unit executes a copy command given the address of the list which uses indirection for copying the data from the input of the unit into the specified portions of the buffer. Then the unit copies the disk file blocks onto an output through the commutator into disk files striped across a multitude of disk storage systems. Also, these two processes may be utilized in the same unit to simultaneously both restore a production from archival tape storage and to play the production as a multimedia data stream.

Computer system and process for transferring multiple high bandwidth streams of data between multiple storage units and multiple applications in a scalable and reliable manner

Multiple applications request data from multiple storage units over a computer network. The data is divided into segments and each segment is distributed randomly on one of several storage units, independent of the storage units on which other segments of the media data are stored. At least one additional copy of each segment also is distributed randomly over the storage units, such that each segment is stored on at least two storage units. This random distribution of multiple copies of segments of data improves both scalability and reliability. When an application requests a selected segment of data, the request is processed by the storage unit with the shortest queue of requests. Random fluctuations in the load applied by multiple applications on multiple storage units are balanced nearly equally over all of the storage units. This combination of techniques results in a system which can transfer multiple, independent high-bandwidth streams of data in a scalable manner in both directions between multiple applications and multiple storage units.

Correlation of media metadata gathered from diverse sources

A DVR, server, or other agent correlates media metadata from diverse sources, like an EPG data provider and multiple video-on-demand (VOD) service providers. Metadata sets from different sources are compared in order to attempt to identify identical programs to which the metadata sets pertain. From at least one metadata set, information about the program that the other metadata set lacks is selected. A "canonical" data structure instance for the program is created. The information that is lacking from at least one of the metadata sources is inserted into that instance. For each source from which a program is available, the DVR stores the identity of that source on the DVR's persistent storage device in association with the canonical data structure instance for that program. The DVR receives search criteria from a user and then searches the stored canonical data structure instance for programs that satisfy the criteria.

Distributed file system of supporting data block dispatching and file processing method thereof

A distributed file system and a file processing method thereof are disclosed. The distributed file system comprises at least two file nodes (1, 2, ..., n), and each file node comprises a metadata server (12, 22, ..., n2), a file access client (11, 21, ..., n1), a file access server (13, 23, ..., n3) and a storage medium (14, 24, ..., n4), and file nodes can access each other. The file processing method comprises the steps of: storing different files in each file node in a scattered way; for each file node, users of the current file node firstly accessing metadata/valid data of a required file in the file node through the file access client of the file node; if the metadata/valid data of the required file are not found in the file node, the users access other nodes through the file access clients. The present invention effectively solves the problem that a metadata server is easy to become a performance bottleneck when a great number of users access hot data concurrently, and can furthest release the storage space of some file nodes by the file processing methods, such as data block dispatching and data block aging, thereby greatly increasing the utilization ratio.
