Similar to other Galaxy S series smartphones, Samsung Galaxy S 4 also comes with a pretty impressive feature-set, but it comes with something that is yet to become a common-sighting in the smartphone arena – High Efficiency Video Coding (HEVC) support.
HEVC aka H.265 is the is the next-generation video coding standard and a successor to H.264/MPEG-4 AVC (Advanced Video Coding), which is currently used by all the video streaming sites, HDTVs and smartphones.
HEVC has just started to become visible on the scene and we saw many companies showing implementations of H.265 at CES and MWC 2013, but its support in a popular and mainstream smartphone like Galaxy S 4 takes it to the whole new level and is likely to have a huge impact on video streaming services and video downloads.
What does HEVC mean for me?
The current state of HD video streaming is crippled because of the inefficiencies of H.264. Where current streaming services using H.264 standard need a minimum internet speed of 5Mbps to stream full HD, with the use of H.265, there won’t needing so much of bandwidth, in fact the full HD video streaming will be possible with just 2-2.5Mbps internet speeds. With HEVC support, the streaming services will also be able to stream Ultra HD videos without the need of truckload bandwidth.
Even if you are not concerned about streaming, even for movie file sizes, with the use of H.265, the full HD movie could now be fit in half the size of current standard.
So, as soon as the video content using H.265 starts to appear in the coming days, Galaxy S 4 will be ready to consume it without any issue unlike any of the current crop of smartphones.
