We propose a joint-source-channel coding (JSCC) scheme that can provide and sustain high-quality video service in spite of deteriorated transmission channel conditions of the second generation of the digital video broadcasting (DVB-S2) satellite broadcasting service. Especially by combining the layered characteristics of the SVC (scalable video coding) video and the robust channel coding capability of LDPC (low-density parity check) employed for DVB-S2, a new concept of JSCC for digital satellite broadcasting service is developed. Rain attenuation in high-frequency bands such as the Ka band is a major factor for lowering the link capacity in satellite broadcasting service. Therefore, it is necessary to devise a new technology to dynamically manage the rain attenuation by adopting a JSCC scheme that can apply variable code rates for both source and channel coding. For this purpose, we develop a JSCC scheme by combining SVC and LDPC, and prove the performance of the proposed JSCC scheme by extensive simulations where SVC coded video is transmitted over various error-prone channels with AWGN (additive white Gaussian noise) patterns in DVB-S2 broadcasting service.
