Abstract: According to examples, a tunable visible light source may include a periodically poled lithium niobate (PPLN) waveguide and a control mechanism to optimize the phase-matching of the PPLN waveguide in response to an input signal with a varied wavelength. The control mechanism may include an electro-optic (EO) tuning mechanism, a microheater-based thermo-optic (TO) control mechanism, and/or an acousto-optic (AO) control mechanism. The control mechanisms may, respectively, generate an electric field, heat, or an acoustic wave to affect a change in refractive index of the PPLN waveguide and thereby optimize the conversion efficiency to maximize the output power of the output wavelength of the PPLN waveguide as the input wavelength is tuned.

Abstract: Techniques for secure fast channel change in live content streaming are described. In some embodiments, during content preparation, a packager and/or an encoder encrypts media content items at both the service level (e.g., by encrypting a first portion of the plurality of segments with a service level access key unique to a service) and the channel level (e.g., by encrypting a second portion of the plurality of segments with a channel level access key unique to a channel associated with the service). On the receiving end, a client device (e.g., a media player) requests a service level access key prior to content acquisition. As such, a client can join any channel on a segment protected with the service level key without waiting for a license for that channel first, and the channel license can be acquired in parallel with the content acquisition during channel switching.

Abstract: A method for assembling an LED apparatus using an epitaxial layered structure comprising a first-type doped semiconductor layer, a second-type doped semiconductor layer, and an active layer between the doped semiconductor layers. The method involves depositing a conductive layer adjacent to and in ohmic contact with the first-type doped semiconductor layer. After forming a pattern masked layer on the conductive layer to expose one or more unprotected mask regions, the unprotected mask region(s) are processed to form a micropixellated structure having micropixel contact areas that are electrically isolated from each other. The method further involves placing a first contact pad over the micropixellated structure to overlap the micropixel contact areas and form a first electrode shared by a set of micro-LEDs. The micropixellated structure is also electrically coupled to a second contact pad that forms a second electrode shared by the set of micro-LEDs.

Abstract: Techniques for rapid video on demand (VOD) media content breach response are described. In some embodiments, during content preparation, a server generates an encrypted media content item by generating a first encrypted portion using a first key derived from a first seed that is of a first type and generating a second encrypted portion using a second key derived from a second seed that is of a second type. In some embodiments, the server classifies the first portion in a first category (e.g., a prioritized category) and the second portion in a second category (e.g., a non-prioritized category). During a breach response, the server repairs the encrypted media content item by re-encrypting portions in the first category, e.g., re-encrypting the first encrypted portion using a replacement key derived from a replacement seed that is of the first type, and updating encryption metadata.
