- [Video — IPTV, Digital TV & FTTH Equipment in Use | Gwincast](https://guang.zhanfengfreezer.com/video/): Most of what decides whether a headend or an access network works happens during commissioning and testing — not in a specification sheet.
- [Optical Transmitters — Optical Transmission | Gwincast](https://guang.zhanfengfreezer.com/transmitters/): Converts the RF or digital signal to optical for transport over fibre between sites.
- [Streaming & Distribution — IPTV & Digital TV Headend | Gwincast](https://guang.zhanfengfreezer.com/streaming/): Delivers the headend output over IP to hotel, campus and operator networks, sized by concurrent viewers rather than by channel count.
- [Optical Splitter — Optical communication | Gwincast](https://guang.zhanfengfreezer.com/splitter/): In an FTTH access network the splitter is where one feeder fibre becomes many subscriber drops.
- [Solutions — FTTH Access, IPTV & Digital TV Networks | Gwincast](https://guang.zhanfengfreezer.com/solutions/): We supply equipment, and we also supply the design that ties it together.
- [Operator digital TV network — Solution | Gwincast](https://guang.zhanfengfreezer.com/solution-operator/): Front-end systems for telecom and broadcast operators — RF receive, encoding, multiplexing, scrambling and modulation, built for continuous commercial operation and large-scale distribution.

- [Multiplexers — IPTV & Digital TV Headend | Gwincast](https://guang.zhanfengfreezer.com/multiplexers/): Combines the individual programme streams into one transport stream, handling the programme and service information that receivers use to build a channel list.
- [Multiplexer — Broadcast television | Gwincast](https://guang.zhanfengfreezer.com/multiplexer/): Combines the individual programme streams from the encoders into one transport stream, which is what the modulator and the distribution side actually consume.
- [Modulators — IPTV & Digital TV Headend | Gwincast](https://guang.zhanfengfreezer.com/modulators/): Puts the transport stream on air as a standards-compliant terrestrial signal. The point where the headend stops being data and becomes a broadcast.
