A video processing system may include an input for receiving interlaced video data arranged in successive frames each including odd and even fields. A processor may be coupled to the input for determining an improper inversion of the odd and even fields based upon a pair(s) of successive first and second frames each including successive first and second fields. The processor may generate a first difference value(s) based upon a comparison between the first field in the first frame and the second field in the second frame, and a second difference value(s) based upon a comparison between a second field in the first frame and the first field in the second frame. The processor may determine an improper inversion of the odd and even fields based upon a comparison of the first difference value(s) and the second difference value(s) for the pair(s) of successive first and second frames.

Video processing system providing interlaced video field inversion detection features and related methods

Single instances of individual codecs are instantiated on different processing elements, and blocks of video frames are interspersed or 'striped' across the multiple instances. An apparatus according to the invention comprises a demultiplexer for receiving the incoming uncompressed video stream and parsing it into blocks, each containing an integer multiple of the inter-frame coding distance, and each block is alternately sent to a different processing element for compression. This allows the output compressed signal to be generated in real-time without dropping frames.

Method and apparatus for compression of a video signal

A system delivers data and includes a plurality of data storage devices. A plurality of servers such as video servers are connected to the plurality of data storage devices and access the data storage devices to provide streaming data to a plurality of clients upon request therefrom. Upon failure of one of the servers, the load on the remaining servers is distributed equally among remaining servers using a distribution algorithm that assigns dual client network connections to server groupings such that the failure of any one server will increase the client load on any remaining server by no more than ceil (C/P) loads, where C is the total number of configured clients that access the plurality of servers in the system and P is the total number of server pairs.

A video media data storage system may include first and second pluralities of data storage devices each arranged in a redundant array of independent drives (RAID) configuration for permitting writing and reading of video media data. The system may further include at least one memory controller coupled to the first and second pluralities of data storage devices for performing mirrored writing of video media data to both the first and second pluralities of data storage devices. The at least one memory controller may also be for generating respective first and second file allocation tables (FATs) including video media data time stamps and validity information for both of the first and second pluralities of data storage devices, and selectively reading video media data from the first and second pluralities of data storage devices based upon the first and second FATs.

Video media data storage system and related methods

A data storage system is described that simultaneously stores incoming data in a plurality of different digital formats linked together to permit economical accessibility and browsing of stored content by providing user access to reduced-resolution versions of stored format. Synchronization information correlates the same content stored in different digital formats to provide a means to reflect an edit of content in one format to the content stored in the other formats without manual editing of content in each format.
