US 9667751

US Patent 9667751, titled "Data feed acceleration," was issued to Realtime Data LLC. The inventors listed are James J. Fallon, Paul F. Pickel, Stephen J. McErlain, and II Carlton J. Melone. The patent was filed on September 14, 2015, and issued on May 30, 2017.

The abstract of US9667751 describes a system and method for accelerating the transmission of broadcast data, such as financial data and news feeds, over a communication channel. This acceleration is achieved through data compression and decompression, which provides secure transmission, effectively increases communication bandwidth, and reduces latency. The patent also notes that encoders associated with particular fields within data packets can be selected to compress those specific fields.

Here's a plain-language overview of the independent claims:

• Independent Claim 1: This claim describes a method for accelerating real-time financial data over a communication channel. It involves receiving a real-time financial data stream, compressing it in real-time using a compression rate that increases the effective bandwidth of the communication channel, and then transmitting the compressed data. The acceleration is achieved when the total time for compression, transmission, and decompression is less than the time it would take to transmit the uncompressed data. The method also specifies that the real-time financial data stream contains multiple types of financial data, and the compression involves selecting a compression algorithm from a plurality of available algorithms based on the type of financial data.
• Independent Claim 12: This claim is similar to Claim 1 but focuses on a system rather than a method. It describes a system for accelerating real-time financial data, comprising a receiver configured to receive the data stream and a processor configured to perform the real-time compression and transmission as outlined in Claim 1. The system also includes a means for selecting a compression algorithm based on the type of financial data.
• Independent Claim 13: This claim describes a method for accelerating data transmission where the "acceleration" is defined by the relationship: [Time to Compress + Time to Transmit Accelerated + Time to Decompress] < [Time to Transmit without Compression]. The method involves receiving an input data stream, compressing the data stream in real-time at a compression rate that increases the effective bandwidth, and transmitting the compressed data. The compression is described as being content-dependent using one or more state machines with compression tables built from a-priori knowledge of the data stream.
• Independent Claim 14: Similar to Claim 13, this claim describes a system for accelerating data transmission based on the defined acceleration relationship. It includes a receiver, a processor configured to perform the real-time compression and transmission, and a mechanism for content-dependent compression using state machines and compression tables derived from a-priori knowledge of the data stream.
