Streaming innovation will drive 4K uptake
While the larger 4K ecosystem slowly gets its footing, a report from The Diffusion Group (TDG) argues that streaming video will be the spark that lights 4K uptake and use. […] First, US consumer broadband speeds have improved, with average residential wireline connection speeds now topping 10 Mbps. A majority of US broadband households are now at or above access speeds that would enable a single 4K stream to be enjoyed on a living room TV, especially given new codecs.
Second, video streaming technologies have continued to improve, a critical trend that optimises available bandwidth such that larger files can be transported more quickly and efficiently. Though still in its early phases, the next-generation codec HEVC (otherwise known as H.265) has been demonstrated to improve codec efficiencies (i.e., bandwidth savings) of between 25 per cent and 50 per cent compared to today’s state-of-the-art codec, AVC. This is a significant improvement, says [Joel Espelien,TDG], as it represents a gain of 50 per cent, which could mean the difference between needing a 15 Mbps and a 10 Mbps stream to deliver 4K content. – Advanced Television
