HD TV over narrow band channel

Our client needed to upgrade their consumer video redistribution system to support HD TV.

The Brief

Our client had a video distribution system for consumers that required an upgrade to support HD TV over a 300MHz coax frequency band. The main challenge was to design and demonstrate a system that could meet the requirement while keeping the bill of materials cost very low.

The Solution

Fundamentally we had to encrypt, encode, modulate, demodulate, decode and decrypt an HD TV stream and present it to the HDMI port of a TV, without breaching HDCP protocol requirements, all for a low-cost consumer electronics price point.

The narrow transmission bandwidth was only possible using a high-order QAM scheme not available in low-cost off-the-shelf components.

To meet the requirements, we created a custom design that used a combination of high-specification third-party IP elements and low-cost standard TV components. Despite the various challenges, we were able to bring all the elements together in a way that met the cost target and provided a high-quality user experience in a consumer product.
