Abstract

Sign languages are natural languages used by the deaf to communicate. Currently, the use of sign language on TV is still limited to a window with a sign language interpreter showed into the original video program. This approach has some problems, such as high operational costs, need for a full-time interpreter. Some works in the scientific literature propose solutions for this problem, but there are some gaps to be addressed. In this paper, the authors propose a solution to provide support for sign language in middlewares compatible with ITU J.200 specification. The solution allows sign language content to be signed by 3D-Avatars when human interpreters are not available. To provide a case study for the proposed solution, they implemented a prototype of it using Ginga, the Brazilian DTV middleware, compliant with ITU J.200. Some tests with Brazilian deaf were also performed to evaluate the proposal.
