METHODS AND SYSTEMS FOR IDENTIFYING CONTENT IN A DATA STREAM.

摘要

Methods and systems for identifying content in a data stream are provided. In one example, a client device receives a continuous data stream and substantially continuously performs a content identification of content in the data stream based on content patterns stored on the client device. The content patterns stored on the client device may include information associated with extracted features of a media file, or a temporally mapped collection of features describing a media file. The client device may determine whether the continuous data stream includes media content, and based on the determination, continuously perform the content identification of content in the data stream at the client device. The client device may query a server to determine an identity of content in the data stream based on receiving an instruction.

A chip-scale optical approach to performing multi-target detection is based on molecular biosensing using fiber-optic based fluorescence or light scattering detection in liquid-core waveguides. Multiplexing methods are capable of registering individual nucleic acids and other optically responsive particles, and are ideal for amplification-free detection in combination with the single molecule sensitivity of optofluidic chips. This approach overcomes a critical barrier to introducing a new integrated technology for amplification-free molecular diagnostic detection. Specific examples of liquid-core optical waveguides and multi-mode interferometers are described; however, they can be implemented in a number of different ways as long as a series of excitation spots is created whose spacing varies with the excitation wavelength.
