Cloud service device, multi-image preview method and cloud service system

摘要

A cloud service device includes a data center that stores video preview images. A first message requesting previewing multiple images from is received from a multimedia device. Multiple offsets corresponding to the multiple images according to the first time interval and the first image number are calculated and time points corresponding to the multiple images according to the multiple offsets and the first preview time point are calculated. The multiple images from the data center according to the calculated time points are obtained and transmitted to the multimedia device to preview.

1. A cloud service device comprising:
a data center storing video preview images; a processor; and a storage system storing one or more software programs in form of computerized codes operable to be executed by the processor, the one or more software programs comprising:
receiving a first message requesting previewing multiple images from a multimedia device, wherein the first message comprises a first preview time point, a first time interval, and a first image number, wherein the first preview time point is a time point requested by the multimedia device, the first time interval is a time interval between two adjacent images of the multiple images, and the first image number is a number of the multiple images, wherein both the first time interval and first image number are set in the multimedia device by a user;calculating multiple offsets corresponding to the multiple images according to the first time interval and the first image number, wherein the multiple offsets indicates time intervals between the multiple images and the first preview time point;calculating time points corresponding to the multiple images according to the multiple offsets and the first preview time point;obtaining the multiple images from the data center according to the calculated time points; andtransmitting the obtained multiple images to the multimedia device to enable previewing of the multiple images by the multimedia device according to user settings.
