Abstract: An intra prediction method and device and a computer-readable storage medium, the method comprising: configuring actual angle modes indicated by relative angle numbers, wherein the relative angle numbers are successively represented within a prediction direction range corresponding to a preset width and height relationship; starting from a starting angle, using a corresponding actual angle mode after sampling preset angle sample points, said starting angle being determined according to the width and height relationship of processing blocks and the prediction direction range corresponding to the preset width and height relationship, and actual angles having a one-to-one correspondence with the actual angle modes.

Abstract: A method for intra prediction includes: obtaining multiple previously reconstructed neighbouring blocks corresponding to a current processing block; determining prediction modes, that are signalled in a bitstream, corresponding to neighbouring blocks of the multiple previously reconstructed neighbouring blocks, to obtain multiple first prediction modes; if the multiple first prediction modes comprise at least two directional modes, taking directional modes comprised in the multiple first prediction modes as first prediction directions; performing, according to a preset operation rule, operation on multiple first prediction directions of the first prediction directions to obtain second prediction directions; obtaining a prediction mode set according to the second prediction directions and the multiple first prediction modes; and performing intra prediction on the current processing block based on the prediction mode set.

Abstract: Distributed transactions are performed over a collection of servers operating as replicas of a data set, where a successful transaction involves meeting a quorum count of replicas that locally commit the transaction. However, performance constraints of data sets and consuming applications may vary (e.g., sensitivity to latency, scalability, and/or consistency), and the performance characteristics of the server set may be partly determined by the transactional commitment and quorum selection. The distributed transaction may be applied by designating the replicas as a set of followers and a leader that initiates the transaction and receives acknowledgments of local commits by each follower. On condition of the acknowledgments meeting a quorum count for the data set according to the performance characteristics of the application, the leader locally commits the transaction and delivers a result.

Abstract: The embodiments of the present invention provide a random selection method, server, client and distributed system. The random selection method includes: generating, by a server, a plurality of objects for an online game, and ordering randomly the plurality of objects; transmitting display information to a plurality of clients, so as to make the ordered plurality of objects displayed on a display screen of each client in a manner of content being unknown, so that each user randomly select from the ordered plurality of objects; and designating, by the server, a user-selected object for the user according to feedback from the client. In this invention, the user may participate in the process of random selection, and random ordering by the system and the random selection by the user are combined, thereby the fairness of the random dealing is ensured.
