🛰️ What is the Difference Between DTT and DTH?
The core difference between DTT and DTH lies in their transmission method:
| Feature | DTT (Digital Terrestrial Television) | DTH (Direct-to-Home Television) |
|---|---|---|
| Signal Type | Over-the-air (terrestrial towers) | Satellite-based signal direct to dish |
| Reception Equipment | Antenna + DVB-T2 compatible TV or decoder | Satellite dish + DTH receiver |
| Geographic Reach | Urban/suburban coverage; signal affected by terrain | Nationwide coverage, ideal for remote areas |
| Cost | Usually free-to-air or very low-cost | Subscription-based with premium content |
| Installation | Simple antenna setup | Requires satellite dish and professional installation |
| Examples | Freeview (UK), StarTimes (Africa) | Dish TV (India), Nova (Greece), DSTV (Africa) |
In short, DTT is more common in urban zones and ideal for free-to-air TV, while DTH offers broader coverage and better quality but often requires a subscription.
📺 DTT on TV vs DTH on TV
Understanding how these systems work on your TV is essential:
- DTT on TV: Most modern TVs support DVB-T2, allowing users to receive DTT channels with just an antenna—no monthly costs.
- DTH on TV: Requires connecting a satellite dish to a DTH decoder. The receiver decrypts paid or free channels, often in HD or 4K resolution.
