A cloud transcoder using download cache scheme

The benefits of transcoding make it possible an incompatible or obsolete contents to be run at any device in a modern format. Nowadays, it is a common way to transcode contents to another format, different bitrates or qualities. As there are some limitations on the source computer which is like thin client with very low H/W specification, it is preferably recommended to be processed on the cloud environment recently. In this paper, we introduce a new way which uses a virtualization technology to provide transcoder resources as a cloud-service with efficient manner. This has the benefit that one can use scalable cloud infrastructure to transcode large amounts of data in a short time. Whereas, it has also drawback that is the time spent downloading source contents into the cloud. So, we design and implement a cloud transcoder with our own efficient scheme which can effectively improve the transcoding process time.
