Title
A channel adaptive video broadcast scheme based on analog coding and delivery
Abstract
Limited to the traditional digital transmission design which forces the source to pick a single bit rate supported by the worst receiver to transmit data, the mobile video broadcast service cannot provide better video qualities to the receivers with better channels. This paper proposes an analog coding and transmission scheme named Realcast to provide channel adaptive video broadcast service. It utilizes a series of linear operations to encode the video frame to maintain the linear relationship between the pixels and the transmitted signals so that the distortion in decoded video is proportional to the added channel noise in signal naturally. Meanwhile, Realcast adopts a distributed source coding scheme which combining the frame difference and coset coding to efficiently remove the inter-frame redundancy and avoid the error propagation. Simulation results indicate that Realcast outperform Softcast and Dcast, the typical analog video broadcast schemes, by nearly 3 dB and 1 dB respectively.
