Publication number: 20100073496Abstract: Remote control units are used to interact with a variety of devices. Modeling of the usage of a remote control unit while interacting with a device helps in (a) redesigning the remote for better usability; (b) dynamic adapting of the remote to provide improved interactions; and (c) characterizing the usage behaviors. In particular, it is very popular to use remote control units to interact with TVs and PVR devices. A system and method for the modeling of a remote usage involves the use of both pre-defined models and discovered models. Specifically, a pattern of usage of a remote control unit is abstracted to be one of either a pre-defined model or a discovered model. The model discovery involves the process of generalization based on a set of particular remote control unit usage patterns. The labels associated with the models help in characterizing the remote control unit usage patterns.Type: ApplicationFiled: September 19, 2008Publication date: March 25, 2010Applicant: SATYAM COMPUTER SERVICES LIMITEDInventors: Sridhar Varadarajan, Amit Thawani, Kamakhya Prasad Gupta

Publication number: 20100057909Abstract: Real-time delivery of multimedia content puts extreme demand on both computational and network resources. Many a times, the requirement is to handle multiple such delivery requirements and as a consequence, the overall delivery efficiency gets affected. Another dimension of complexity is that (a) the multimedia content to be delivered may not always be highly reliable, and (b) the network may also be not highly reliable. In such a situation, it becomes even more difficult to satisfy the quality of service requirements. When content to be delivered to multiple destinations is available at multiple sources, there is an opportunity to overcome the above mentioned complexity. The system and method for efficient delivery in a multi-source multi-destination network involves pulling of data from the multiple sources by measuring quality of service and reliability parameters, and efficiently loading the systems and the network in a cooperative manner.Type: ApplicationFiled: August 27, 2008Publication date: March 4, 2010Applicant: SATYAM COMPUTER SERVICES LIMITEDInventors: Sridhar Varadarajan, Srividya Gopalan

Publication number: 20100049739Abstract: Multimedia content usage is on the rise and hence, it is becoming increasingly necessary to automatically analyze the multimedia content in order enhance the effective applicability and usage of the content. The richness of a multimedia content demands multi-fold analysis of the content and further, this richness also leads to openness and vastness. Hence, the outcome of the multiple analyses techniques needs to be carefully analyzed in order to avoid limited or inconsistent content description. A system and method for bounded analysis of multimedia using multiple correlations addresses the issues related to richness and vastness of a multimedia content to enable describing of the multimedia content in a maximally consistent manner. Such a content description is very useful in the semantic characterization of multimedia.Type: ApplicationFiled: August 20, 2008Publication date: February 25, 2010Applicant: SATYAM COMPUTER SERVICES LIMITED OF MAYFAIR CENTREInventors: Sridhar Varadarajan, Amit Thawani, Kamakhya Prasad Gupta

Publication number: 20100011021Abstract: Personalized services and targeted services demand the exploitation of context—say, context of an environment, context of a product, context of a service, and context of a customer or user or individual. In order for the personalized and targeted services to have a greater impact, the identified context used by a context aware processing engine needs to be accurate and current. Such an up-to-date context is called as context map and a system and method for generating a customer-specific context map involves the processing of customer transactions, abstracting and generalizing these transactions into entities, and inter-relating these entities. The context map, for example, is useful in ad targeting in mobile environments, and in quicker and efficient problem resolution in contact center environments.Type: ApplicationFiled: July 11, 2008Publication date: January 14, 2010Applicant: SATYAM COMPUTER SERVICES LIMITED OF MAYFAIR CENTERInventors: Sridhar Varadarajan, Srividya Gopalan, Swetha Mukunda Kurup, G.S.
