Methods and systems for multimedia content
Despite the massive advances in digital electronics, telecommunications networks, and electronic devices in the past 20 years our engagement with video content is essentially unchanged to that of the first video recorders as it is merely where we access it and upon what we access it that have changed. It is still a passive experience. Accordingly, it would be beneficial to provide multimedia content that facilitates user engagement and transactions directly through their viewing of the multimedia content in shareable multimedia content elements. Such engagement and transactions may be accessing additional informational content linked to specific elements within the multimedia content or triggering the purchase of an item contained within the multimedia content. Embodiments of the invention may support monetization, analytics, secondary multimedia content, website functionality and micro-websites. |

Content-based navigation for recordings
Navigating a video recording based on changes in views of the recording's visual content is described. A content-based navigation system receives a recording including visual content and audio content. The content-based navigation system then determines a content scale for navigating the recording relative to an overall number of new or updated views of visual content during playback of the recording.

Identifying original and copy using ultraviolet light to reveal hidden security printing features
A first pattern and the second pattern in an original include relatively lighter markings within a relatively darker background. The first pattern differs from the second pattern by including non-printing patches between the relatively lighter markings.

Request multiplexing
The embodiments provide request multiplexing whereby a server receiving a first request for content clones and issues the cloned request to an origin to initiate retrieval of the content.

Reducing qubit energy decay and correlated errors from cosmic rays in quantum processors
Large algorithms can be run on a quantum computer only if quantum error correction is used to lower logical qubit errors.

These structures are designed according to the electron-phonon interactions and constraints from electromagnetic radiation to make large reductions in the induced errors so that error correction works properly. |
