Multi-Platform IPTV Subscription Service

I need a complete IPTV subscription solution that works seamlessly on Smart TVs, mobile devices (iOS / Android), web browsers, Android box TVs, and Windows PCs. The service must include:

• Live TV streaming with minimal buffering
• A rich Video on Demand and series library
• An accurate, easy-to-navigate Electronic Program Guide
• Multi-language interface and content labeling

I’m looking for an end-to-end build: middleware setup, secure user authentication, payment gateway integration, and branded client apps or responsive web front ends for each platform listed above. Scalability, DRM or equivalent content-protection measures, and straightforward admin tools for channel and VOD management are important.

Please outline the technologies you plan to use, any hosting or CDN recommendations, and a rough timeline from prototype to launch. Provide links to previous IPTV or streaming projects if available—I’d like to see examples that prove you can deliver a stable, feature-rich service.
