Wireless broadcasting systems, such as Digital Video Broadcasting (DVB), are subject to signal degradation, having an effect on end users' reception quality. Clearly, reception quality can be improved by increasing signal strength. This, however, comes at a significantly increased energy use, with adverse environmental and financial consequences, notably in either sparsely populated rural regions, or overly built and difficult to penetrate dense urban areas. This paper discusses our ongoing work on an alternative approach to improving reception quality, based on the collaborative repair of lossy packet streams among the community of DVB viewers. We present our main idea, the crucial design d..
