Here we describe the components of a 3D video remote rendering system for mobile devices based on cloud computing services. We also discuss the main design choices and challenges that need to be addressed in such a system.
The system will be composed of three main components:
- Mobile receiver(s)
- Adaptation proxy
- View synthesis and rendering cloud service
Transmission is to be carried via unicast over an unreliable wireless channel. A feedback channel would be necessary between the receiver and the proxy. This channel would be utilized to send information about current/desired viewpoint, buffer status, and network conditions.
Because of the limited wireless bandwidth, we need efficient and adaptive compression of transmitted views/layers. In addition, an unequal error protection (UEP) technique will be required to overcome the unreliable nature of the wireless channel.
- What is the format of the stored video files?
- How many views (and possible depth maps) need to be sent to the receiver?
- What compression format should be used to compress the texture images of the views?
- What compression format is efficient for compressing the depth maps without affecting the quality of synthesized views?
