Ultra High Definition Television (UHDTV) technology, also known as UltraHD or 4KTV, is already being embraced by content producers in both film and television. As broadcasters begin to investigate UHDTV as a way to significantly improve the viewer experience, operators will need a way to deliver premium content at higher resolutions than possible with current services.
This paper will discuss recent technical advances that will allow cable providers to efficiently and cost-effectively deploy UHDTV offerings in the near term. It describes how new technologies and industry standards, such as HEVC/H.265 video compression, BT.2020 color gamut, HDMI 2.0 digital interface, and HDCP 2.2 content protection must be supported in next-generation set-top boxes to enable cable providers to deliver next generation content.
