MPEG4 vs. H.264

In recent months we have seen numerous companies introduce H.264 (aka MPEG4 Part 10) as the default codec in cameras, video players and other similar devices. Personally, I have been bombarded by e-mails from Chinese and Taiwanese manufacturers with large bold fonts in a red colour claiming that their cameras now support H.264. I therefore found myself asking the question what this hype is all about and decided to do my own research rather than accepting other people’s claims as de-facto standard.

H.264 video codec’s are quite complicated and for the sake of this article I shall try to keep it as simple as possible. The main advantage of H.264 over all other compression formats is that it can achieve higher quality video at similar data rates or relatively lower data rates for same quality video. This is all well and good, but the question to be ask is “by how much” and “at what cost”?

During my research I have seen many graphs and calculations claiming that the difference in compression and bit rate between H.264 and MPEG4 are as large as 30 or 40 percent and in some cases even 50 percent. These calculations do not list their assumptions and test criteria and therefore the only way to be certain was to conduct a bench test myself.

The bench test consisted of an H.264 camera pointing towards a busy street and another H.264 in an empty office pointing towards some desks and chairs. Both cameras were connected wirelessly to an access point that is hard wired to a switch and a Netbook (Asus EEE PC 901 running Windows XP) and a Desktop PC (Core Duo 1.6GHz and 4 GB memory running Windows XP) connected to the switch with a CAT 5 cable. Both cameras are of the same make and model while Internet Explorer (running the manufacturer’s ActiveX control) was used to view the cameras. A 3rd computer was connected the network to monitor the traffic on the network, act as a gateway and provide DHCP and some other services to the network.

Accessing the cameras was quite straight forward; however the first thing that caught my eye was that the Netbook was suffering to decode the H.264 compression when viewing the camera pointing at the busy street. Processing power topped 85% usage and accessing both cameras at the same time from the Netbook generated a large amount of frame loss and a drastic reduction in frames per second. The Desktop seemed to perform very well with a stable video and healthy frame rate even when both cameras where accessed. I took some data rate readings from the gateway and proceeded to remove the H.264 cameras and replace them with Y-cam MPEG4 cameras.

The Netbook seemed more relaxed and accessing both cameras produced no frame loss or reduction in frame rate. Processor usage was down to around 30% when accessing both cameras which is a huge improvement over the H.264 cameras. There seemed to be no difference on the Desktop. Again, data rate readings were taken from the gateway and I returned to my desk for some number crunching.

The results

When accessing the camera pointing at the empty office there was a difference of just under 30% less bandwidth usage when viewing the H.263 camera over the MPEG4 camera. On the other hand, when viewing the camera pointing at the busy street the difference wasn’t much. The H.264 camera only managed to achieve just above 6% better data rates then the MPEG4. This translates to having enough bandwidth to add an extra camera with every 16 cameras you install which is hardly ever the case in a domestic or small business environment.

In conclusion, the only way to achieve a 30% higher compression is to have the camera facing a still image which defeats the purpose of having a camera in the first place. Also, if your computer isn’t a beefed up version with loads of spare processing power and a generous amount of memory then H.264 is not for you.

Another point worth mentioning is that MPEG4 is more widely supported by multi-camera software and hardware manufacturers (NVRs) and is far more stable than H.264.

This is obviously not a definitive test and I’m sure there are benefits to using H.264, however, in my opinion the disadvantages and higher hardware costs tend to out-weigh the benefits in a practical environment. Therefore I wouldn’t recommend the switch from MPEG4 for to H.263 just for the sake of switching to a newer compression.

Coenzyme Q10. It’s a bit of a buzz word in the skin care industry, and many people buy their skin care products based purely on finding Coenzyme Q10 on the label. But what exactly is it and why would you want to know? And what is Nano-Lipobelle H-EQ10?

So what is Coenzyme Q10, or what can be known as Co Q10? It’s a vitamin like substance found in the cells of our bodies, including our skin, and is naturally occurring. It is also found in a variety of foods that we eat, including various meats, including heart and liver, different types of fish and even peanuts. Coenzyme Q10 is important to our bodies as it assists in the production of energy, but particularly for those interested in serious skin care, Coenzyme Q10 is a powerful anti oxidant.

What is an anti-oxidant and what does it do? Our bodies contain substances known as “free radicals”. These are molecules that have lost an electron, and this is caused naturally in our bodies, or we can get free radicals from our food. And free radicals can be a problem for our bodies.

Free radicals cause damage in our bodies by seeking to replace that missing electron. If you remember back to your school physics days, a molecule with an electron missing is unstable, and will seek to replace it. And free radicals do that by taking an electron from another molecule in our body, and this causes damage to our cells, and our skin, by increasing the visible effects of aging and causing an increase in skin damage. This includes lines and wrinkles on our skin.

And as we age our store of free radicals increases. And our supply of naturally occurring Coenzyme Q10 reduces. Not good.

Now back to Coenzyme Q10. As an anti oxidant it helps reduce the effects of those nasty free radicals on our skin, and in our bodies. An anti oxidant supplies that electron to the free radical in a non damaging way, and therefore neutralizes the effect of that free radical molecule.

All good, and useful for our skin, helping reduce the visible effects of aging by reducing the damage caused by the free radicals. Provided we have enough Coenzyem Q10 in our bodies, and if we don’t then we need to get some more.

So if you see Coenzyme Q10 on the label of your skin care or anti aging product you’re getting more into your body, and you’re mopping up those free radicals. Not so fast.

There’s a couple of problems. Firstly, Co Q10 is expensive, and so many of our big brand name mainstream skin care products may have it listed on the label, but there’s not a whole lot in there. Just enough to say so on the label so people buy it.

Secondly, if you’re getting it through your skin care products you need it to be in a form that will penetrate the skin, it’s no good if it sits there on the surface and doesn’t get in to where it’s doing it’s work.

And most big brand skin care and anti aging products have it there in a form that doesn’t really penetrate the skin. But as long as it’s there listed on the label and people are buying the product they’re happy.

Is there an answer? Enter Nano-Lipobelle H-EQ10. It’s a modern version of Coenzyme Q10 and it works much better.

Nano-Lipobelle H-EQ10 is a combination of Co Q10 and vitamin E in a “nano emulsion” form. That sounds complicated, but basically it means that the particles are broken down into microscopic sizes so that they can penetrate the skin successfully. And studies have shown that, when applied in cream this nano emulsion Nano-Lipobelle H-EQ10 is extremely effective in combatting wrinkles, lines and sagging.

And it stimulates the bodies own production of collagen and elastin, which is extremely useful.

But what about the other problem, the cost? Well actually Nano-Lipobelle H-EQ10 is even MORE expensive, so you won’t find it in the big brand name anti aging skincare products you see on the shelves. However the good news is that there is one very small niche company that produces excellent, and guaranteed, skincare products that contain high levels of Nano-Lipobelle H-EQ10, and at an extremely competitive price.

They don’t advertise on TV so that keeps the price down, they let their products do the selling.

Bet you’ve never heard of them though. About the worlds best skincare products, with Nano-Lipobelle H-EQ10, and almost unknown.

Biological need is everything for people who are aged 18 years or more. Because at the time of our biological needs are met, we will feel very satisfied, and passion will definitely very excite. But not everyone can enjoy the sexual satisfaction of his to meet his biological needs, because at the position where we do not have a partner for making out, while we will lust rising sexual relations, we will very definitely need a way to satisfy our sexual desires, one way is by Buy Sex Toys. That way we will be able to enjoy our sexual satisfaction again even though we’re not having a partner, whether it’s because the distance between us and our partners, or also because at that time also we’re not having a partner.

So, rather than us just to look for our sexual gratification with exploring any commercial sex workers, we will stay away from all the existing diseases such as AIDS. Because of how it does, we certainly will be people living with AIDS if we deliberately choose to satisfy our sexual desires with making out with commercial sex workers. Whatever happens, it is a biological necessity must remain channeled. Because it is in a position like that of a human biological needs must be met.

So it would not hurt you choose to buy sex toys than you have to explore the commercial sex workers in order to channel your sexual needs. Because somehow, the biological needs of sex must remain in the channel, because that’s what one of our needs as well as humans. So, if you are someone who is lonely, but you still need distribution for biological things, you call us to get the best sex toys that we have for your sexual satisfaction.
