IPTV (Internet Protocol Television) uses IP networks. It delivers TV content via the internet. IPTV differs
from cable and satellite. It provides both live and on-demand content. Service providers usually
distribute IPTV.
IPTV can serve enterprise video needs. However, it’s less common due to complexity. Network latency
and scaling issues arise. Subscriber-based models are more prevalent. IPTV uses TCP/IP for video
delivery.
IPTV vs Non-IPTV: What is the Difference?
Traditional non-IPTVs use light or radio. Fiber-optic cables transmit light pulse. Satellites transmit content
via radio waves. Internet protocol television uses broadband internet connections. Service providers deliver content online. IPTV relies on internet infrastructure. Delivery methods differ between IPTV and non-IPTV.
| Aspect | Traditional non-IPTV | IPTV |
| Delivery Method | Light pulses or radio waves | Broadband internet connection |
| Transmission Medium | Fiber-optic cables or satellite | Internet |
| Service Providers | Cable or satellite companies | Internet service providers |
Traditional non-IPTV relies on established broadcasting. IPTV leverages the internet for delivery. Each
has distinct infrastructure requirements.
Why Do People Choose Internet Protocol Television?
Internet protocol television offers the same content differently. People prefer IPTV for its flexibility. This flexibility enhances user experience significantly.
IPTV’s flexibility applies in three ways. It offers more viewing options. It provides better content
customization. IPTV supports multiple devices seamlessly.
Flexibility On When You Watch
Cable and satellite TV are real-time. Viewers watch live broadcasts only. Recording devices are needed
otherwise. You watch what’s available when it’s on.
Internet protocol television uses video on demand. It also supports time-shifted media. Watch shows after live broadcasts. IPTV removes rigid TV schedules and no need for DVR programming.
Flexibility on How You Watch
Internet protocol television offers flexibility beyond TV screens. Watch favourite shows on various devices. No need to be tied to TV. IPTV apps support multi-device viewing. Enjoy shows on tablets, smartphones, and laptops. Cable providers offer similar options but are limited. IPTV provides broader multi-device accessibility.
| Limited availability | IPTV | Cable TV |
| Multi-device | Yes | Limited |
| Accessibility | Broad Range | Limited availibility |
| Flexibility | High | Limited |
IPTV enables viewing on multiple devices. Cable TV offers limited multi-device access. IPTV excels in
flexibility and accessibility.
Flexibility with The Network
The term “IP” in IPTV refers to Internet Protocol. It’s the same as in your IP address. IPTV uses internet
protocol for communication. IP networks offer enhanced flexibility. They enable two-way interactivity.
This is unlike traditional one-way connectivity.
| Aspect | IP Network | Traditional Cable/Satellite |
| Interactivity | Two-way | One-way |
| Flexibility | High | Limited |
| Control Options | More | Less |
With IP networks, users have more control. They can personalize their viewing experience. IPTV provides
enhanced user interactivity.
How does Internet Protocol television work?
Internet protocol television content is often delivered via managed networks. Managed networks ensure quality of service. They use dedicated connections like DSL. Compared to the public internet, managed networks offer control. Operators can ensure reliability, uptime, and bandwidth.
Content delivery is efficient and reliable. In traditional TV delivery, the Multicast format is used. All programs broadcast simultaneously. Viewers change channels to select programs. IPTV uses Unicast format. Only one program is sent at a time. Content remains on the provider’s network. When viewers change channels, new streams are transmitted. Set-top boxes or other devices are required. These include Wi-Fi routers or broadband connections.
Video on Demand
VOD streaming offers video on demand. Watch whenever you want. No time limit on content availability.
You choose what to watch. Service delivers it via the Internet. Examples include Netflix, Hulu, and Amazon Prime Video. These are OTT streaming services. Many niche services are also available.
Here’s a table comparing different VOD models:
| VOD Model | Description |
| Transactional VOD (TVOD) | Users can watch TV shows and movies for free but have to watch ads while viewing |
| Subscription VOD (SVOD) | Users pay a monthly fee for access to a library of TV shows and movies |
| Advertising-supported VOD (AVOD) | Users can watch TV shows and movies for free but have to watch ads during viewing |
Subscription VOD (SVOD) involve a monthly fee. Advertising-supported VOD (AVOD) is free with ads.
Time-shifted media
Time-shifted IPTV resembles VOD with limitations. Content has expiration dates. It’s commonly used for
catching up on recent programming. Unlike traditional VOD, time-shifted IPTV has limits. Content
availability is not indefinite. It’s often used for recent programming. Users catch up on news or events.
Here’s a table comparing time-shifted IPTV with VOD:
| Feature | Time-shifted IPTV | Video on Demand (VOD) |
| Availability | Limited duration after airing | Indefinite availability |
| Use Case | Catching up on recently aired programming | Accessing a library of TV shows and movies |
| Content Expiration | Common | Rare |
