ProgDVB

ProgDVB - the universal and very power software for watching digital TV and listening to radio channels.

ProgDVB and ProgTV is two is 2 independent user interfaces which can work together from one folder at one list of channels, settings etc.ProgTV is a modern interface with support for modern monitors. Easy to control with mouse/keyboard and remote control (HTPC). ProgDVB is a classic interface with many features but no remote control support. You can try both and choose.

For reasonable money I can prepare the custom ProgTV/ProgDVB version (for Windows or/and the Android) for your requirements. For example with those, and only those functions which are required for your an IPTV/OTT or the specific device. It is also possible create new player based on my engine and 15+ years of experience in digital TV. Or even mine participation in your project in similar area. I will be glad to discuss any ideas.
