Video Codecs, they’re not all created equal

 

We see h.264 used in so many applications.

 

 

This is one of the most incredible things about ClearOne’s ViewPro AV over IP solution.  ViewPro can decode streams that some other device encodes, or native H.264/265 devices like IP cameras.  Or, send a stream to ViewPro directly from a PC/Mac, iOS or android device or others.

 

Same is true at the other end, you don’t need one of our ViewPro decoders, simple devices like an AppleTV, or an IPTV set-top box can decode our streams.  Recording or playback on an NVR (network video recorder) is easy, watching streams on a PC/Mac/iOS/Android, etc is easy too.

 

 

It’s the beauty of being standards based.  But h.264 isn’t known for its high quality streaming, or so we are conditioned to think.  H.264 and 265 High Profile, in both 4:2:0 and 4:4:4 variants are what we use in ViewPro. With High Profile h.264 compression, you would be hard pressed to notice any difference in signal or image quality, with fast motion video, or fine text like spreadsheets.  Whatever the content, High Profile, h.264 encoding and decoding will give you an output that looks just as good as your original content.

 

 

High Profile H.264 is the codec used on BluRay discs, and most often in broadcast/Cable TV, it is extremely powerful in its compression capability, and the key is, within ViewPro we put the priority on low latency, latency that comes extremely close to some of the other AV over IP products that require 10 times, or even 100 times the bandwidth of ViewPro.

 

 

When you come across a project that needs long-distance signal distribution, and/or a large number of sources or displays, you really should give ViewPro a chance.  Once you see everything ViewPro is capable of, I’m sure you will agree it is ideally suited for the Pro A/V community.  And we haven’t even discussed advanced features like TRUE VideoWall processing.  We can save that for next time.

When ‘Standard’ is the only option

 

A lot can be said for standards. For instance, could you imagine how difficult it would be if the gas pedal wasn’t always on the right? Look at the recent troubles several car manufacturers have had, including lost lives over messing around with how an automatic transmission’s shift level works.

 

Standards work in all parts of life. So, as AV professionals, why have we had a variety of non-standard ways of delivering content?

 

The excitement of AV over IP products implies that maybe we will start using standards to replace balun and HDBaseT products for a more standards-based approach. But the more IP products that come to market, the more proprietary streaming products that emerge. The trouble with a proprietary stream is it locks the end user into a single solution, with limited expansion capabilities.

 

With a true standards-based solution, you can build an eco-system of devices, but are not tied to a single manufacturer, you can mix and match based on budget, features and the architecture of the system. ClearOne’s VIEW® Pro streaming solution leverages the power of H.264 streaming, thereby using visually Loss-Less streaming algorithms, to allow crystal-clear, ultra-high-quality audio and video at very low latency, all at a very low overall bandwidth (typically 8MBb/s). Additionally, based on what the clients’ needs are, we can control and manipulate streams that we don’t even encode, such as those natively streamed from an IP security or PTZ camera, or a conferencing codec with H.264 capabilities or from a computer on the network. Similarly, if perfect frame synchronization is not required, or the need for video windowing, or other advanced features is not required at some displays, there are many, easy, low-cost ways to decode the stream, such as Apple® TV or other H.264 stream viewers, or simply watch the stream on a PC, MAC, IOS or Android device.

 

By leveraging the power of Standards, we open the client to an eco-system of devices that will be a viable signal distribution infrastructure that will stand the test of time. To take this one step farther, ClearOne’s VIEW® Pro solution leverages H.264 streams, yet provides ULTRA low latency, low bandwidth and the best possible image quality, yet provides advanced capabilities like Video Wall processing, windowing processing and other neat features like USB HID and native RTSP and UDP streaming.

 

If you haven’t tried VIEW® Pro yet, why not? I’m sure it will exceed you current standard.
