When it comes to quality of IPTV, there are two big vague issues: what exactly determines quality of the stream and which codecs can we use to actually watch IPTV. To start with the first one, unlike broadcast TV companies that usually offer a standard signal format, IPTV companies boast of the ability to tradeoff video quality. What does it provide?

It provides a nice possibility to lower the cost of video/service quality and bandwidth. The good news is such “soft adjustment” can help if you want to save some money, but the main disadvantage is that such adjustment can have detrimental effects on the perception of the quality of IPTV service.

The majority of IPTV services and its initial implements are relatively high. As the industry transitions to allow independent Internet television service providers to provide TV services over broadband connections, these firms can manage how much bandwidth and quality will be allocated to the client. For the time being, the data transfer fees for ISP connections was about $0.6 per 1 GB of data transfer. Speaking about the streaming data transfer rate of standard television quality digital video signal is about 500 kBytes (per second) – this results in a data transfer rate of 30 MB per minute. It is fully possible to reduce the data transfer rate of the TV channel to save money on the data transfer. The medium quality of IP television data rates is from 500 kbps to 1.5 Mbps.

What is about the low one? Low quality ranges from 100 kbps to 500 kbps. So it is possible for IPTV service provider to tradeoff quality for reduced cost. But each IPTV service has its own bandwidth requirements and the majority of customers are vague about calculation of the needed bandwidth requirements. All you need to do is to ask a customer service of your IPTV company what bandwidth requirements they have. For instance, BBC HD streams require at least 4mbmp to keep the decent quality. Another example is Netflix – it offers a SD stream (480p) of 1750kbps and 720p HD stream at 3000kbps. Once you’ve found out the bandwidth requirements of your IPTV service, you can set the quality of the video and service to keep balance between saving money and good quality.

The second big issue about IPTV is codecs.

Internet Protocol Television technology is a new TV generation that requires up-to- date codecs or programs for audio/video streams in the Web. If your audio/video player requires some codecs, you can google it and find the needed ones in a few clicks. Keep in mind it is better to download or buy any required codecs using official websites. If you want to avoid any troubles with codecs, use the most popular and applicable video players: VLC media player, Light Allow, KMPlayer, Zoom Player or any other ones.
