In this paper, we propose a real-time video streaming system over narrow networks that provides high-quality video services. The suggested system uses the raptor code, a forward error correction code, to support the reliable and stable data transmission in the narrowband networks. Also, the proposed system adaptively controls the raptor parameters (source symbol size, the number of source symbols, and code rate) according to the narrow network condition and the remaining buffer status. The proposed system is fully implemented on android devices and examined by using a real-time video transmission. Experimental results showed that the proposed system provides high-quality streaming services over the narrowband networks.
