H.265 gets pushed forward with Broadcom’s 4K-capable BCM7445

Autore: ExtremeTech

H.264 has been around for years. When OS X 10.4 shipped back in April of 2005 with support for the standard, its quality-to-size ratio was unmatched. Since then, it has become the de facto standard for everything from streaming video to recording video on phones and cameras. Despite it popularity, the technology is getting long in the tooth. Now H.265, the next generation video standard, is moving forward as Broadcom has announced a new quad-core ARM-based chip, the BCM7445.

With a maximum resolution of 4096×2160 at 60 frames per second (yes, it can handle 4Kp60), this combination of powerful hardware and a next-gen video standard is downright exciting. With the ability to handle four video streams, this chip could drive four 1080p displays simultaneously.

Sadly, we won’t see its benefits anytime soon. While Broadcom says that it has samples available now for interested companies, it won’t be ready for large scale production until at least next year. Sporting a 28nm process, Broadcom won’t say how much it will cost. Unfortunately, that probably means it’s expensive. After all, it’s not cheap at the bleeding edge.

Simply put, H.265 allows for a higher quality picture that takes up less space in exchange for higher processor usage. For example, a video encoded at 1920×1080 at 24fps in H.265 will look just as good as the same video encoded with H.264, but takes up roughly half the space. That’s not all this standard has up its sleeve — it can support much higher quality video as well. At an amazing 7680×4320 high-end resolution, H.265 will support full 8K video while effectively H.264 maxes out at 4096×2160 (4K). H.264 content pretty much exclusively uses 8-bit color channels, while H.265 focuses heavily on 10-bit color channel support allowing for more range and color accuracy from content creators.

While devices like smartphones and tablets that have limited processing capabilities and battery life concerns won’t be making the switch to H.265 for a while yet, web video and high-end theater and television content will want to jump at it as soon as possible. Companies like Amazon and Netflix are undoubtedly drooling at the idea of being able to push high quality content using half the bit rate it uses currently. While Google is pushing hard to make VP8 and VP9 attractive to content providers with a no-cost license, its looking like H.265 will likely serve as the default video standard for most content going forward just like H.264 has for the past eight years.
