Abstract: A multimedia playback method includes: playing first multimedia data, switching from playing the first multimedia data to playing a multimedia frame corresponding to a target starting point of second multimedia data, based on a media switching operation, the second multimedia data including multimedia frames corresponding to a plurality of time points, the plurality of time points including pre-configured P candidate starting points, and the target starting point belonging to the P candidate starting points, and switching, during the playing of the second multimedia data, from playing a first multimedia frame in the second multimedia data to playing a new multimedia frame corresponding to a new starting point, based on a target triggering operation, the first multimedia frame being a multimedia frame played at a moment at which the target triggering operation is performed, and the new starting point being a candidate starting point other than the target starting point. .

Abstract: A non-metallic cabling continuous oil pipe, relating to the technical field of oil mining in oil fields, is disclosed. Said oil pipe includes an inner liner tube, the inner liner tube which is used to form a passageway for medium transportation. An outer wall of the inner liner tube is provided with a cable embedded layer and a protection sleeve in sequence, the cable embedded layer including cables and a plurality of reinforcement belts. The reinforcement belts are used to resist torsional deformation and to bear an axial tension. The protection sleeve is used to prevent the cables from being worn.
