In January, a new video codec called H.265 (also known as
High Efficiency Video Coding (HEVC) was approved by the ITU-T. This is significant for a couple of reasons:
It needs only half the bit rate of the best codec out
there today (H.264) to provide the same or similar quality video. You can even see it in this YouTube video.
Given that video is a massive use case for mobile data
networks, estimated to be about half of mobile data traffic today with
expectations of it garnering even more in the coming years, the improvement in
quality while reducing the bandwidth requirement is a huge development.
Our engineering team doesn’t believe it will result in a 50
percent bandwidth savings even though it’s half the bit-rate. That’s because a lot goes into the file size of a video,
including computing power. Instead, we estimate it will initially save at least
25 to 30 percent in bandwidth and then up to 50 percent as the algorithm and
optimization techniques advance later.
Use cases would also determine the savings with pre-encoded videos
garnering up to 50 percent of bandwidth savings, while real-time applications such as
viewing football games online would be only 25 percent of savings.
Does this mean it will solve the mobile congestion issues?
It’s too soon to say for sure. Some other things will need to happen first. For
example, the ecosystem will need time to capture H.265 into devices, so it will
be some time before we have H.265 devices en mass in the market. And there could be a coming clash with WebRTC
codecs that could potentially delay widespread adoption.
But assuming this is all worked out, would this new codec solve
mobile congestion issues? Not completely, but it’s a contributing factor. As I’ve also written before, there are many methods
to solve mobile congestion, such as new technologies like H.265, and adding
more bandwidth from deploying new towers, as well as offloading data traffic to WiFi – all optimization techniques enabled by Dialogic
solutions. All will be important to
this. This is an example of a new
technology helping out. And let’s
remember human nature, too. Once it’s
easier and faster to view video, we’ll want more and larger file sizes. And the more we watch, the more strain the
networks will experience. So this new
technology won’t solve mobile congestion.
We’ll still need to consider multiple strategies and techniques.
We are receiving really good updates on the trending technologies. Appreciate your effort in taking time for blogging. Thanks.
