Abstract: Bitrate-adaptive segmentation is performed for transcoding a video stream uploaded to an online video platform for hosting and later playback to platform users. The video stream is segmented into chunks based on prediction-based bit costs determined for frames of the video stream rather than based on scene changes detected within the video stream. The bitrate-adaptive segmentation includes determining inter-prediction bit costs and intra-prediction bit costs for frames of the video stream based on information indicated within a pass log based on a first pass encoding of the video stream, determining chunk boundaries for segmenting the video stream into a chunk based on the inter-prediction bit costs and the intra-prediction bit costs for the frames, and transcoding the chunk to produce a transcoded video stream.

Abstract: A rapid shutdown device for rapidly de-energizing a photovoltaic module system is disclosed. The rapid shutdown device includes power lines connected to a photovoltaic string of modules on a roof of a structure. A high voltage switch on a first power line is disconnected when the high voltage switch is open.

Abstract: In various embodiments, systems and methods for generating attested video image data are provided. In some embodiments, an ISP pipeline incorporates a secure cryptographic signing mechanism to digitally sign content-based outputs in a way that attests to the authenticity of the process by which the content was processed before output from the camera. The ISP pipeline may include a hardware security module that inputs video image data from an image sensor, and generates an attestation package that includes attestations about the video content, in combination with an attestation of how it was produced, and signs those attestations together using a key to produce an output comprising attested media data. The ISP pipeline may apply supplemental attestations to the attestation package representing facts associated with the video content that evidence the authenticity. The digital signature applied to the attestation package may use a zero-knowledge proof to describe the signing key.

Abstract: Solutions for evaluating source code generators use offline and online evaluation stages. Offline evaluation includes separating each of a plurality of input passages of software code into a plurality of constituent blocks. Each code generator (of a plurality of code generators) generates an equivalent block corresponding to each constituent block. A coding score is determined for each equivalent block (for each code generator), and the coding scores are aggregated across the equivalent blocks to provide an aggregate score for each code generator. A ranking of the aggregate scores is used to down-select to a fewer number of code generators for online evaluation. For this stage, the code generators output passages of software code, and user acceptance of the code generators' outputs may be used for further ranking and down-selection. Some examples weight the coding score according to a code utility estimate of the constituent blocks for which equivalent blocks are generated.
