Infrastructure upgrade needed for clearer HD images
How do you think R&D spending will fare in 2009? The problem is not necessarily the set itself, but the limitations of the delivery pipeline that brings the signal to the set," said Bocko. The challenge for the HDTV industry is to sync up the fast-improving TV capability with the content delivery infrastructure, which is developing at a slower pace. While consumers are adopting HDTV in greater numbers, anecdotal evidence indicates that product return rates to retailers remain high.
Bocko sees an opportunity to apply Corning's research in glass substrates and fiber optics to pinpoint possible solutions. Corning's targeted research into display network requirements could help benchmark the requirements needed for optimal HDTV performance. By sharing our proprietary research findings, we hope to benefit the entire HDTV market," said Bocko.
He added in an interview that the disconnect between HDTV receiver capability and network delivery performance is partially due to the speed at which HDTV technology has arrived. What's more, sets that formerly broadcast only television programming and movies are now sophisticated multimedia portals. Thus, content providers are increasingly churning out higher-quality digital offerings, further increasing the need for a robust content delivery pipeline.
Even high-end HDTVs may come up short due to network quality issues, including content delivery bandwidth, bit rate and video compression constraints. Corning researchers are developing the infrastructure needed to support future display technologies.
For instance, using an optical testbed to emulate fiber-to-the-home, cable television and digital subscriber loop networks combined with new display technologies, Corning engineers have been able to analyze how content delivery and network capabilities affect HDTV viewing. Among the metrics are variations in bit and compression rates, display size and type and network characteristics.
Our initial research indicates that for each display type viewing quality improves with bit rate. And the rate of improvement grows for more advanced displays and larger screens," Bocko said. Corning will release its HDTV research results later this year. We believe the data will lead to technical modifications of displays and networks which ultimately will lead to improved image quality for consumers," Bocko said.
