Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Method for Replacing PIDs in a Transport Stream from a
Convert analog device input (VHS, camcorder, etc.) to
MPEG-2 transport stream and inject into a broadcast transport stream by
remapping PID assignments.
Kim Annon Ryal
Description of the Invention:
On a fully digital set-top box (STB)
(e.g. A-lite) there is no way to connect an analog input. This means that I
cannot copy my tape of my vacation onto the DVR embedded in the STB so I can
use the networking facility to distribute it throughout the house.
As a "side-car" device, direct
an analog input (RCA, S-video, etc.) to an encoder. The encoder transforms the
analog signal into a MPEG-2 transport stream.
This "analog" transport stream is then inserted into the
broadcast transport stream by overlaying a program stream (set of PIDs) in the
broadcast transport stream with the "analog" transport stream. PAT
and PMT replacement could also occur to identify this new program stream.
An STB connected to this device, via the usual connection, could
receive the analog input as just another program. Tuning, reception, decoding
and display would be transparent.
Multiple analog inputs on the "side-car" would permit
insertion of multiple programs.
Adding additional tuners to the "side-car" would permit
insertion of multiple programs from multiple transponders. This would permit a
STB with a single tuner to receive multiple prog...
