Joint source-channel coding for underwater multimedia transmission | ITU Journal | Webinar

Описание: Underwater acoustic communications present unique challenges for multimedia transmission, particularly in supporting oceanic research, the blue economy, and ecological monitoring through sensor networks. While traditional coding methods have served well, the limited bandwidth and variable channel conditions of underwater acoustics demand innovative communication solutions that optimize source-channel coding jointly.
This webinar presents two groundbreaking approaches: first, an image transmission system that reconceptualizes the coding problem as a language-translation task, where input sequences are transformed based on estimated channel conditions using Long Short-Term Memory (LSTM)-based sequence-to-sequence models. Second, a novel analog video transmission scheme is introduced, specifically designed for small submersibles and Internet-of-Things (IoT) devices, that not only achieves reliable multicast communication but also doubles the video framerate while maintaining transmission fidelity under bandwidth constraints. The system’s potential for analog implementation makes it particularly power efficient – a crucial factor for underwater deployments.
Through experimental evaluation using real-life acoustic Channel Impulse Responses (CIRs) the speaker will demonstrate the effectiveness of these approaches in revolutionizing underwater acoustic multimedia communications.
