Video streaming has changed in the past couple of decades. It was a long path from videos that consisted of still pictures to what we have now. A huge help in video technology development brought the IPTV encoder. It is a solution for technological transition.

IPTV video encoding infrastructure makes it possible to stream live and on-demand content via the Internet. Let’s observe this topic closely.

What is an IPTV encoder?

IPTV video encoding is the process of converting RAW video files into digital format. As a result, the video is saved as a video instead of many images.

The process is also necessary for compatibility and efficiency with certain devices and applications.

Encoding is also the process of compressing a large video file into smaller chunks that are more suitable for delivery through the Internet. IPTV encoder makes a video transferable through the Internet.

After this process is complete, the video is stored on a server.

What is Decoding?

Decoding is a part of the encoding process. Decoding involves unpacking the compressed data for transmission.

Furthermore, the IPTV decoder’s job is to decode a video into a format that the receiving device can play. IPTV decoders can also prevent piracy and unauthorized access to video content.

Viewers should have a decoder to decode an encoded video and watch it on their devices. The most common type of decoder is a set-top box. It is a small device connected to the display and receiving the video for further decoding.

What is transcoding?

The transcoding process is related to encoding. It is a conversion of a video from one format into another that browsers and devices can support. Sometimes, this process involves changing size and video quality. Due to transcoding, the load on the hardware is lowered, and the speed of transmission is improved.

This process is necessary for a video to meet the technical requirements of the device it will be played on, whether it is a computer, a tablet, a smartphone, or a Smart TV.

Video transcoding allows businesses to reach more customers.

As the demand for videos available on the Internet is increasing, the demand for video encoding and transcoding is also growing.

Encoding and transcoding

Encoding and transcoding may seem to be similar processes, but they are different. The transcoder takes an already encoded video and makes some adjustments. A video may get a watermark or be converted to another format.

Encoding and transcoding may affect video quality, but it is not necessary. There may be some data loss, but the video can still be watched on receiving devices. The alterations of these two processes are too small. They are hard to see with the human eye.

Final Thoughts

Video streaming is booming. Viewers like these services because they offer a lot of convenience and other perks. Nobody likes being tied to a television schedule. Video streaming platforms allow people to watch videos whenever they want and wherever they want.

Videos are available via applications that viewers always take with them everywhere. It means that they have access to video content at any time. Moreover, they can binge- watch on video streaming services, unlike traditional television, which usually offers one part of a series or show at one time.

As video streaming services are so popular, it means that encoding, transcoding, and decoding are important processes to provide a platform operation.
