| 20090125459 | METHOD AND SYSTEM FOR RULE-BASED CONTENT FILTERING - A system and method for content-filtering of data containers in a network supporting versatile communications services are disclosed. The content-filtering system is integrated with a content-adaptation system. Several server units handle data containers formulated at source according to different protocols. A content filtering process relies on characterizing each component of a container to produce a set of content descriptors and producing a set of binary conditions for each component according to a preset criterion for each descriptor. A set of rules is devised where each rule applies a respective Boolean expression to a subset of the conditions to prescribe a respective content-editing action. Methods of specifying and evaluating a rule's Boolean expression are disclosed. A formal graph is used to define inter-dependence of rules. | 05-14-2009 |
| 20090126020 | ENGINE FOR RULE BASED CONTENT FILTERING - An engine for editing contents of data containers has a set of processors which hosts a set of controllers, each controller coupled to a respective set of transcoders. A memory device stores an array of Boolean variables characterizing the contents of a container, and an array of encoded rules for determining needed content editing, if any. The Boolean variables are determined according to content descriptors and respective criteria. A graphical user interface enables a user to provide the descriptors, the criteria, and the encoded rules. Each transcoder applies the encoded rules to specific containers. A transcoder also performs container adaptation functions which may modify contents of a container to be compatible with a respective receiver. The engine receives containers from clients through a network and directs each container to a respective controller. | 05-14-2009 |
| 20090280844 | MODULAR TRANSCODING PIPELINE - A modular transcoder software system for transcoding a multimedia message includes a collection of software modules and objects for the dynamic construction of a series of complex, related or unrelated operations in the form of a transcoding pipeline. The transcoding pipeline provides a hierarchy of operations, such that they can be organized and optimized with the aim of being able to execute the entire hierarchy in a single pass. Additionally, external plugins can customize the mechanism of building the pipeline by altering, adding to, or removing construction knowledge. | 11-12-2009 |
| 20100325079 | METHOD AND APPARATUS FOR EMPLOYING RULES TO FILTER STREAMING DATA - Content filtering of data containers is based on defining content types, receiving identifiers of a set of rules applicable to each content type, and determining dependence of at least one rule on other rules. The identifiers are sorted into rule strata where rules within each rule stratum are independent of each other and rules within each rule stratum beyond a first stratum depend on at least one rule of at least one preceding rule stratum. Upon receiving a data container of multiple components from a network, a content type is determined for each component. Rules of rule strata specific to a content type of a component are applied starting with rules of a first rule stratum and proceeding sequentially to selected rules of succeeding rule strata. An apparatus for content filtering stores processor-executable instructions for arranging rules in rule strata and sequentially applies successive rules to data containers. | 12-23-2010 |
| 20100325164 | METHOD AND APPARATUS FOR CONCURRENT FILTERING OF MULTIPLE COMPONENTS OF STREAMING DATA - Content filtering of data containers of multiple content types is performed using multiple filtering modules operating concurrently. An apparatus for content filtering has a set of content-specific filtering modules and a network interface for parsing a received data container into components and directing each component to a respective filtering module. A filtering module edits a component of a specific content type according to respective rules. A multiplexer combines edited components produced by the set of filtering modules to form an edited data container. A root module applies a set of basic rules to a data container and any attachments. In an alternative configuration, the apparatus employs multiple filtering modules each applying rules for all content types. Received data containers are distributed among the filtering modules and an output module arranges edited data containers of a data stream in proper sequential order. | 12-23-2010 |
| 20100332618 | METHOD AND APPARATUS FOR FILTERING STREAMING DATA - A method of content filtering of data containers of multiple content types is based on generating a set of encoded filters and a set of encoded rules for each content type. Each encoded filter is expressed as a respective operator, from among user-defined operators, and two operands including a content descriptor and a descriptor criterion. A filter has a binary state and a rule may be based on a single filter or a number of selected filters. An apparatus implementing the method has a user interface for receiving user-defined configuration data, a configuration module for generating a set of encoded filters and a set of encoded rules for each content type, a network interface for receiving data containers from a network and transmitting filtered data containers to the network, and a filtering module for applying the rules to received data containers. | 12-30-2010 |

The transcoding pipeline provides a hierarchy of operations, such that they can be organized and optimized with the aim of being able to execute the entire hierarchy in a single pass.
