64 results about "Proprietary format" patented technology

A proprietary format is a file format of a company, organization, or individual that contains data that is ordered and stored according to a particular encoding-scheme, designed by the company or organization to be secret, such that the decoding and interpretation of this stored data is easily accomplished only with particular software or hardware that the company itself has developed. The specification of the data encoding format is not released, or underlies non-disclosure agreements. A proprietary format can also be a file format whose encoding is in fact published, but is restricted through licences such that only the company itself or licencees may use it. In contrast, an open format is a file format that is published and free to be used by everybody.

Method, apparatus, and communication protocol for transmitting control data with an improved error correction capability in a digital cordless telephone system

A more robust error correction capability is provided for the control data passed between a remote handset and its base unit in a DECT digital cordless telephone. According to the DECT standard as implemented in digital cordless telephones, one communication channel is used for control data and another is used for the voice data. While the DECT standard allows proprietary formats to be transmitted in the voice data channel, it fixes the information transmitted in the control data to ensure interoperability. In accordance with the principles of the present invention, the data rate of the voice data is reduced from a conventional 32 kb / s to provide bandwidth for error protection information. The error protection information may include, e.g., a redundant copy of the control data to provide the basis for a diversity scheme to improve the reliability of the control data transmission. Additionally, or alternatively, the error protection information may include error correction information, e.g., forward error correction information, relating to the control data and / or to the voice data to improve the reliability of the control data and / or voice data being transmitted. The error protection information may be combined with the voice data in the single communication channel time slot by, e.g., multiplexing, or apportioning of the time slot.

Realtime processing of streaming data

The invention described here is intended for enhancing the technology domain of real-time and high-performance distributed computing. This invention provides a connotative and intuitive grammar that allows users to define how data is to be automatically encoded/decoded for transport between computing systems. This capability eliminates the need for hand-crafting custom solutions for every combination of platform and transport medium. This is a software framework that can serve as a basis for real-time capture, distribution, and analysis of large volumes and variety of data moving at rapid or real-time velocity. It can be configured as-is or can be extended as a framework to filter-and-extract data from a system for distribution to other systems (including other instances of the framework). Users control all features for capture, filtering, distribution, analysis, and visualization by configuration files (as opposed to software programming) that are read at program startup. It enables large scalable computation of high velocity data over distributed heterogeneous platforms. As compared with conventional approaches to data capture which extract data in proprietary formats and rely upon post-run standalone analysis programs in non-real-time, this invention also allows data streaming in real-time to an open range of analysis and visualization tools. Data treatment options are specified via end-user configuration files as opposed to hard-coding software revisions.

Secure digital video disk and player

A method for recording data on an optical medium is disclosed. In one embodiment, the method includes receiving main data from a data source, determining a plurality of data frame values in response to the main data, inverting at least one selected bit in at least one of the data frame values to generate a plurality of encoded data frames, scrambling the encoded data frames by a feedback shift register to generate scrambled data frames, generating ECC values in response to the scrambled data frames, adding the ECC values to the scrambled data frames to generate an ECC block, rearranging the ECC block to generate a plurality of recording frames, encoding the recording frames by an eight-to-sixteen modulation (ESM) encoder to generate code words, adding sync values to the code words to generate a plurality of physical sectors, and recording the physical sectors on the optical medium. A complementary method for reading and decoding data from an optical medium is also disclosed. These complementary encoding and decoding schemes provide a method for creating and reading proprietary format DVDs which may not be read or copied by conventional DVD players. These encoding and decoding schemes result from relatively minor modifications to existing DVD standards, allowing many standard system components to be used and thereby making the encoding / decoding system relatively easy and inexpensive to implement.
