I just returned from training in Atlanta where I completed the DigitalMedia-Engineer certification. DMC-E certification is required to deliver systems that comply with the HD Digital Transport and Distribution System (HD-DTDS) specification. HD-DTDS is a comprehensive roadmap that clearly defines the critical aspects of system design and installation that must be followed to assure reliable system performance. Crestron guarantees and fully supports any DM system installation that conforms to the HD-DTDS standards.
