Bandwidth Limitations is the main reason!
TV channels operate within specific bandwidth constraints, especially when using traditional broadcast methods like cable or satellite.
Delivering content in 1080p resolution requires significantly more bandwidth compared to lower resolutions like 720p or 1080i.
Bandwidth is a finite resource, and broadcasters must balance the quality of their content with the number of channels they can offer within their available bandwidth.
Compatibility Issues
Another reason for the limited adoption of 1080p resolution by TV channels is compatibility.
While many modern TVs support 1080p resolution, there are still a significant number of older models in use that may not be capable of displaying content in this resolution.
Also, some broadcasting equipment and infrastructure may not fully support 1080p transmission, requiring costly upgrades for widespread adoption.
What about cost?
Broadcasting content in higher resolutions incurs additional costs for TV channels.
This includes upgrading equipment, investing in more robust infrastructure to support increased bandwidth requirements, and potentially negotiating new agreements with cable and satellite providers.
These costs must be weighed against the perceived benefits of broadcasting in 1080p, especially considering that many viewers may not discern a significant difference in picture quality between 1080p and lower resolutions on smaller screens or from typical viewing distances.
So, Cable companies will probably never broadcast in 1080p because 720p and 1080i are already good enough, and there’s no need to upgrade.
