PROBLEM TO BE SOLVED: To provide a system and a method that provide high-quality video streaming in radio video communication.SOLUTION: A system comprises a digital encoder, an analog encoder, and a power controller. The outputs from the digital encoder and the analog encoder are superposed, and transmitted to a receiver using a digital decoder and an analog decoder on a radio channel. The system uses the high-order modulation of digital-coded data, the optimal power distribution of digital data and analog data, optimal subcarrier allocation to increase a water-filling gain, and compression sensing to reduce packet loss during radio communication. In addition, the system provides the optimal power distribution of multi-view texture information and multi-view depth information obtained with a plurality of cameras, and improves video quality according to a free viewpoint rendering procedure on the basis of analysis using channel quality, camera geometry, and polynomial expression fitting.SELECTED DRAWING: Figure 2 |
