Method of managing video snapshot of receiving bitstreams of a video and bitstream parameters of the received bitstreams from a server through a network channel. The electronic device is connected to the server. The server encodes the video into an encoded file using an encoder of the server. The encoded file comprises a plurality of bitstreams. The plurality of bitstreams in the encoded file comprising a plurality of enhancement layers. According to a selection of a user of the electronic device, a snapshot grade is determined. According to the received bitstreams and the determined snapshot grade, additional enhancement layers which are not comprised in the received bitstreams are acquired from the encoded file in the server through the network channel. Based on the acquired additional enhancement layers, a video snapshot is generated.

Electronic device and method for managing video snapshot

In a method for splitting an image for encoding purposes, a largest coding unit (LCU) of the image is obtained, the LCU divided into a plurality of 2N&#xd7;2N blocks, the 2N&#xd7;2N blocks examined sequentially, and a determination made as to whether or not the current 2N&#xd7;2N block needs to be split according to a pixel variance of the current 2N&#xd7;2N block. The method further determines whether a block merging operation needs to be executed for the LCUs according to an average value of pixels of each of the 2N&#xd7;2N blocks if the current 2N&#xd7;2N block does not need to be split.
