This disclosure describes, in part, techniques for generating captions for audio content items. For instance, a system may store a user profile that is associated with audio content items. When a user associated with the user profile requests captions, the system may determine which audio content items have available captions and which audio content items do not have available captions. For the audio content items that do not have available captions, the system may determine priorities for the audio content items. The system may then cause the captions to be generated based on the priorities. When the captions are generated, the system may update statuses of the audio content items to indicate that the captions are available. The system may further store the captions in a database that is accessible to the user. |

Storage and retrieval of virtual reality sessions state based upon participants
Once participants participate in a video conference the state of information during that video conference is retained for those participants. At a future time, when those participants again meet in a video conference the state of information that was retained is retrieved and presented for them again in the subsequent video conference based upon their identifiers. Information such as the whiteboard, the chat window, shared files, camera settings, images, background, video recording, etc. are retrieved and automatically presented in the new video conference. Alternatively, a participant may be asked if the state of information from a previous video conference should be retrieved. When a participant joins a conference, the current participants grant permission or not for the current contents to be viewed by the new participant. When a participant leaves the conference, or when they all leave, a triggering condition saves the state. Participants may join in a cross-platform conference and all content from a session in another platform is retrieved. Virtual reality may also be used. |

Regulation of SPF policy terms
Sender Policy Framework (SPF) is a widely used method of distinguishing authorized email from unauthorized email. SPF policies are published into a domain's DNS and then looked up and evaluated by mail receivers. Due to the complexity and limitations of the SPF specification, implementation mistakes and risks are widespread. This problem is compounded by the common practice of nesting SPF policies which introduces hidden risks, particularly exceeding DNS lookup limits. Embodiments of the present disclosure enable new SPF techniques such as selectively inactivating parts of a policy by introducing a virtual-all term, designed to secure against the third-party term inclusions in the policy. When the primary policy is online, the virtual-all term may serve as a terminate policy evaluation much like a traditional “all” term. If the primary policy is offline, a “fail open” may be produced, allowing policy evaluation to proceed into previously inactivated segment of the policy. |

The light beam is also modulated externally with an RF information-carrying signal. The high frequency signals are at least twice a highest frequency of the RF signal.

Protograph quasi-cyclic polar codes and related low-density generator matrix family
Data communications and storage systems require error control techniques to be transferred successfully without failure. Polar coding has been used as a state-of-the-art forward error correction code for such an error control technique. However, the conventional decoding based on successive cancellation has a drawback in its poor performance and long latency to complete. Because the factor graph of polar codes has a lot of short cycles, a parallelizable belief propagation decoding also does not perform well. The method and system of the present invention provide a way to resolve the issues by introducing a protograph lifting expansion for a polar coding family so that highly parallelizable decoding is realized to achieve a high coding gain and high throughput without increasing the computational complexity and latency. The invention enables an iterative message passing to work properly by eliminating short cycles through a hill-climbing optimization of frozen bits allocation and permutation. |
