Abstract: Video containers are expanded to encapsulate auxiliary data and metadata linking video content with relevant portions of auxiliary data for download during playback of particular video content. Auxiliary data is parsed into areas of interest and associated with the video content including the same areas of interest. During playback a viewer is provided access to relevant portions of the auxiliary data according to the encapsulated metadata describing the relevant portions.

Abstract: A processor may receive, from two or more nodes in the blockchain, respective consideration from each of the two or more nodes at a first time. The processor may receive respective updates from each of the two or more nodes at a second time. The processor may determine whether a single node of the two or more nodes is available after the respective updates. The processor may designate the single node as the block generator node.

Abstract: A distributed transaction processing system, comprising a peer node associated with a blockchain network. The peer node may be adapted to record join-time parameters for a plurality of blockchain nodes, compare a first join-time parameter for a first node of the plurality of blockchain nodes to a remainder of the join-time parameters for a remainder of the plurality of blockchain nodes, calculate, based on the comparison, a transaction signature probability (TSP) for one or more nodes within the plurality of blockchain nodes, select according to the calculated TSPs, a signature node from among the one or more nodes having calculated TSPs to sign a transaction block, and calculate, by the selected signature node, a digital signature for the transaction block.

Abstract: Aspects utilize computer processors to restart a hung process. The processors are configured to, in response to determining that a child process that is executing within an operating system is in a hung state, pause a parent process that is executing within the operating system, wherein a data operation of the parent process is dependent upon a data output of the child process, determine a cause of the hung state of the child process, ready the parent process to restart as a function of the determined cause of the hung state of the child process, and in response to determining that the parent process is ready for restart, notify the operating system that the child process is ready for restart, restart the paused parent process and restart the child process.
