There are various kinds of hardware on which application work in cloud. To these applications available in cloud computing, we need to develop the interface for each hardware.

When we develop the interface, the quality is required. Though it is easy to modify the interface by adjusting displaying area, the quality cannot be assured. By modifying the interface with a3s system, the application can be executed in cloud computing for different hardware with keeping quality.

In cloud computing, we have a problem in the quality of movies but also bandwidth and processing capability. a3s system keeps high quality in the condition of small image dimension or narrow bandwidth.

When we utilize the application on cloud computing, we have to reduce the elapsed time before displaying the user's client machine. This time is called as latency time. If it takes long, is longer, users feel uncomfortable feeling, and get carsick in driving simulation.

a3s system is optimized the contents transmitted of applications to enhance transmitting speed in cloud computing.

For example, H.264 which is one of the latest video format and many image contents are developed in this format. As it has many advanced features and excellent scalability, many types of video contests, from low quality of video to high-definition video are available.

In a3s system, when the image is compressed in H.264 format, it compressed by x264 encoder and is decompressed by h264. These implementations are authorized by GPL license. x264 encoder is recognized as the best and highest speed encoder now.
