  • Patent number: 11729439
    Abstract: Systems and methods configured to detect and manage video transcoder latencies are described. A manifest is received and is used to request video segments included in a manifest playlist. A transcoder having an input and output is used to transcode video segments. A delta time for a first SCTE-35 marker between the transcoder input and the transcoder output is determined, where the delta time corresponds to a transcoder latency. A determination is made as to whether a corrective action needs to be taken with respect to the latency, and such corrective action is taken as needed. The corrective action may include a transcoder reset. The manifest may be a text file and may be in the form of an HLS or DASH manifest. Additionally, streaming latencies may be reduced by switching content distribution systems, increasing the number of edge systems distributing content to clients, and/or by increasing video cache memory.

  • Patent number: 11411650
    Abstract: The present disclosure is generally directed to a component bridge that couples to a feedthrough device to provide additional component mounting surface area within a TOSA housing, and preferably, within a hermetically-sealed TOSA housing. The component bridge includes a body that defines a component mounting surface to couple to electrical components, e.g., one or more filtering capacitors, and a notched portion to provide an accommodation groove. The component bridge includes at least one projection/leg for coupling to a mounting surface of a feedthrough device. The accommodation groove of the component bridge allows for other electrical components, e.g., RF traces, to be patterned/disposed on to the mounting surface and extend at least partially through the accommodation groove while remaining electrically isolated from the same. Accordingly, the component bridge further increases available component mounting surface area for existing feedthrough devices without necessity of re-design and/or modification.

  • Patent number: 10989870
    Abstract: In general, a TOSA consistent with the present disclosure includes a light driving circuit coupled to a hermetically-sealed light engine. The hermetically-sealed light engine includes a housing defined by a plurality of sidewalls. The housing defines a cavity that is hermetically-sealed to prevent introduction of contaminants that would otherwise reduce optical power. The hermetically-sealed light engine optically couples to an external arrayed waveguide grating (AWG), or other multiplexing device, by way of an optical receptacle. The optical receptacle can include a waveguide implemented external to the hermetically-sealed cavity and can include, for instance, an optical isolator, fiber stub, and fiber ferrule section. Thus, the external AWG and associated external optical coupling components advantageously allow for the hermetically-sealed light engine to have a cavity with dimensions relatively smaller than other approaches that dispose an AWG and associated components within a hermetically-sealed cavity.

  • Patent number: 10958019
    Abstract: A smart electrical plug supports one or more electrical outlets and one or more universal serial bus (USB) outlets for charging electrical devices. Electrical power consumed through the one or more electrical outlets may be measured individually or in combination and reported via a wireless communication channel. The smart electrical plug may be implemented by a plurality of printed circuit board assemblies and distributed within a housing to reduce the effects of heat dissipation. The smart electrical plug may further reduce heat dissipation by utilizing one or more electrical circuit approaches.
