Abstract: An embodiment provides a distributed transcoding method using a plurality of servers. The method includes receiving a request for a first video file from a first terminal. The method also includes segmenting the video file based on a play time of at least portion of the video file and a performance rate of a plurality of second servers. The method also includes transmitting the segmented video file to the plurality of second servers, which includes transmitting the segmented video file of a greater size to the second server having a higher performance among the plurality of second servers and transmitting the segmented video file having a smaller size to the server having a lower performance among the plurality of second servers. The method also includes receiving a transcoded video file from the plurality of second servers. The method also includes transmitting the transcoded video files to the first terminal.

Abstract: An apparatus and method with register sharing are provided. In one general aspect, a method of operating a processing apparatus includes determining whether there is shared data that is used by each of threads in a plurality of threads sharing a shared memory, based on an instruction that has been decoded, based on determining whether there is shared data that is used by each of the threads in the plurality of threads, determining whether an address of the shared data corresponding to each of the threads in the plurality of threads is stored in an address-to-register mapping table, based on a result of either the determining whether the address is stored in the address-to-register mapping table, mapping the address of the shared data to a shared register corresponding to the shared data, and loading the shared data based on the shared register.

Abstract: A storage system includes a storage device having a nonvolatile memory with a first and a second physical address and a host configured to insert a first journal logical address and a first target logical address into a journal mapping table. The storage device includes a flash mapping table storing the first journal logical address mapped to the first physical address, and the first target logical address mapped to the second physical address; a circuit configured to write the first journal data to an area of the nonvolatile memory to the first physical address corresponding to the first journal logical address according to the first mapping state, based on the journaling command; and to change the first mapping state of the flash mapping table to a second mapping state in which the first target logical address is remapped to the first physical address, based on the checkpointing command.

Abstract: Provided is an image encoding method including extracting feature points from a picture; generating at least two clusters by performing feature point clustering on the extracted feature points; determining at least two split sections in the picture, the at least two split sections respectively corresponding to the at least two clusters; parallel-encoding the at least two split sections; and generating a bitstream including information about the at least two split sections. A size and a shape of each of the at least two split sections may be individually determined.

Abstract: According to one embodiment, a scheduling method for load balancing in an electronic device such as a server when performing multiple transcoding operations includes performing a first transcoding operation in order to transmit at least one moving image file to a first terminal. The server receives a request from a second terminal to transmit at least one moving image file while performing the first transcoding. The server performs a second transcoding operation in order to transmit the requested moving image file to the second terminal. The server monitors output frame rates of the first transcoding operation and the second transcoding operation, to control the output frame rates.
