    摘要： Systems and methods are described for securely distributing metadata using a block chain. The system generates a block for a distributed blockchain ledger such that the block includes an encrypted metadata item of a media asset. The system, at a first time, transmits the block for storage in the distributed blockchain ledger such that a copy of the distributed blockchain ledger is stored by the first computing device and a second computing device. The system generates a smart contract that includes a decryption key for the encrypted metadata item and an identifier of the second computing device. The system transmits the smart contract for storage in the distributed blockchain ledger. The smart contract is configured to be automatically executed at the execution time that is later than the first time, to provide the second computing device with the decryption key for the encrypted metadata item.

    摘要： Systems and methods for generating a channel sequence for display via an abbreviated on-screen guide are disclosed herein. Channel tuning commands are entered via a user interface of a computing device. Channel tuning data, which describes channel transitions caused by the channel tuning commands, is stored in a buffer. Based on the channel tuning data, a channel family comprising a plurality of channels is generated. A determination is made as to whether a currently tuned channel is included in the channel family. In response to determining that the currently tuned channel is included in the channel family, an on-screen guide, which comprises an abbreviated channel listing of the plurality of channels of the channel family, is generated for display.

    摘要： Systems and methods are disclosed including techniques for rendering a 360-degree media content. Techniques disclosed include receiving a 360-degree media content and associated metadata that include a classification of a first spatial region from the received content. Techniques disclosed further include determining that a detected user movement is associated with a rendering of the first spatial region and determining whether the classification associated with the first spatial region complies with a stored user preference. If the classification violates the user preference, a path for gradually shifting the content rendering from a currently rendered spatial region to a spatial region that complies with the user preference is determined, and the received content is rendered according to the determined path.
