  • Patent number: 8347108
    Abstract: The proposed system defines an automated safe reprogramming of software radios. The essence of software radios is to enhance or alter the functionality of a mobile terminal by using software. This means that the required software is downloaded onto a mobile terminal on the fly to meet the critical and necessary needs of the user. Lot of caution needs to be exercised while downloading the necessary software components on the fly. The proposed invention automates the validation and verification of the downloaded component by suggesting (a) a variety of signatures; (b) a means for defining multiple zones and verification of zone-specific signatures; (c) a means for computing the signatures of the downloaded component in the multiple zones; and (d) a means for verification of the downloaded component based on the signatures. The objective is to define the safeness of the downloaded component based on multiple signatures to be validated in different zones.

  • Patent number: 8090670
    Abstract: 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.

  • Patent number: 8086692
    Abstract: 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.

  • Patent number: 8065302
    Abstract: Annotations for a multimedia repository facilitate an efficient indexing, searching, and retrieval of the content from the multimedia repository. These annotations are an effective description of the content and it is very useful to have systems that automatically analyze the content to generate the annotations. A multimedia content, comprising video, audio, and textual data, is organized at shot level, scene level, segment level, multi-segment level, and full-length level. The multimedia content annotation is a providing of computer processable description of the multimedia content. Due to the multilevel organization of a multimedia content, it is required to provide annotations at various levels as well. A system and method for annotation aggregation uses the annotation at a lower level to arrive at an annotation at the next higher level. Such multilevel annotations are very useful in applications such as targeted content delivery.

  • Patent number: 8036464
    Abstract: Text segmentation based on topic boundary detection has been an industry problem in automating information dissemination to targeted users. A system for automatic segmentation of ASR output text involves boundary identification based on “topic” changes. The proposed approach is based on building a weighted graph to determine dependency in input sentences based on bi-directional analysis of the input sentences. Furthermore, the input sentences are segmented based on the notion of segment cohesiveness and the segmented sentences are merged based on preamble and postamble analyses.

  • Patent number: 7680753
    Abstract: A fault identification system analyzes alarm information and the associated contextual information to identify the occurred faults. The contextual information is based on usecases, transactions, and functions associated with the electronic system under consideration. Multiple detectors that form part of knowledge repositories are used in the process of fault identification.
