Mobile Video

Mobile video demand is exploding. With the people in the multimedia access whenever and wherever possible needs of the increasingly urgent, TV or receiving services will emerge as the times require. For the service provider, which is a good thing, they are hope for its product portfolio to add new consumer applications; but at the same time, the support infrastructure equipment presents a great challenge, not to mention the potential problems: from media gateway video required performance must meet the requirement of the low power consumption, so that not give infrastructure caused heavy burden, but also must meet the cost control and sustainability requirements.

New processor and streaming architecture in video transcoding achieve obvious advantages -- and the infrastructure equipment commonly used processor technology, some new product power / density ratio is improved by 15 times, can help to create a high performance, low power consumption of the mobile video platform solutions.

Mobile video and TV or receiving service development

In the second half of 2009, according to some market analysis shows, YouTube of average daily handle about 1000000000 video access. In 2008, the number is 6000000. More the report points out, to 2015, will have 12000000000 sets of equipment ( including television, computers, laptops, netbooks and smartphones ) accessed 500000000000 hours of video information. (source: Intel ). By 2013, mobile video telephone retains the quantity will achieve 400000000 (source: inquiry Thai ). In 2012, the video will account for all Internet traffic of 90%; in 2013, the video will account for all mobile communication flow 70% (source: Cisco ). Obviously, the wide and easy access to the video content is a huge consumer demand, and the demand is increasing day by day. To meet this demand and maintain access to the ease of use, for processing and delivery of such video content server, streaming video and media gateway number must be accompanied by processing work load surge and exponentially expanding. With the sound signal and other typical Internet content, video needs higher level processing capacity, particularly when the video is transmitted to the various types of browser on a client device is even more so. Of course, to enhance the processing ability also means the increase of energy consumption.

Video coding conversion is the processing load in the main part, combined with the growth, this task has a huge potential energy consumption growth, the existing infrastructure to make very great pressure.

On the demand of video transcoding

To distribute video from various capture equipment, they have different resolution and coding ability. For example, the application of MPEG4 encoding CIF smart phone or H.264 encoding a 720 pixel camcorder can be used as capture device. Similarly, for receiving the video client devices also have different decoding capability ( ability to decode for device function or processor cycles vary ), for example, QCIF H.263 cellular phone, decoding HD H.264 high-end notebook computers. Video uploaded to the network broadcast and / or storage, its purpose is to hope that anyone can see, however, there is a lack of rigid or general video exchange standard. To meet this objective, video distribution and Internet service provider must provide transparent code conversion function.

In addition, the video transmission expectations has become the requirements of real-time video transmission, and does not need to be a part of or the entire video download file to the client device in a buffer, on Internet television and monitor system especially. The real-time transmission demand to increase the video transmission system load, at the same time, also increases the energy consumption.

NesC

NesC is an extension to C, which is based on the embodiment of the TinyOS structured concept and execution model and design. TinyOS is for sensor network node designed an event-driven operating system, sensor network node has a very limited resources ( for example, a program memory. 8K bytes, 512 bytes of random access memory). TinyOS use nesC to write.

Brief introduction

1: the structure and content of the separation of program components, which are assembled together (" wiring" ) constitute a complete program. Component definition of two kinds of field, for a description of them (including their interface request name ), another for their complements. Internal operation form of collaborative assembly. Control can be threaded through its interface into a component. These threads are produced in a job or a hardware interrupt.

2 according to the interface settings illustrate component function. Interface can be provided by the components or use. It is to provide the interface for users, by the use of the interface performance users completed its operation required function.

The 3 interface is bidirectional: they described a group interface provider ( instruction ) of the function and a group of the user interface ( events ) to achieve the function of. This allows a single interface to complex interactions between components ( for example,. When a certain event in a callback occurred before, some of the events of interest registration ). This is dangerous, because the TinyOS all of the command ( for example. Send packets ) is not interrupted; they completed by an event ( sent ) mark. Through the narration interface, a component can call send instruction unless it provides the realization of sendDone events. Usually instructions down the call, for example, from the application components to those closer to the hardware call, and the event to invoke. Specific primitive events and hardware interrupt is associated ( this correlation is determined by the system, so in this reference manual without further description).

5 component via the interface static linked to each other. This increases the operation efficiency, support rubust design, but also to allow better program static analysis.

5 nesC based on the integrity of the program code generated by the compiler needs to design. This takes into account the good code reuse and analysis. One aspect of this example is nesC compile - time competition data monitor.

6 nesC collaboration model based on once you begin until finishing the homework, and an interrupt far source can interrupt operation. NesC compiler markers by the interrupt source induced potential competition data.

Tips: accelerate fat burning 6 Tips

1 human body after eating the body temperature rises, thereby speeding up the energy consumption. So, eat three meals a day than only eat two meals energy consumption when the greater. Intake of protein, energy consumed most, useful for weight loss.

2 when the in vivo muscle increases, basal metabolic rate will rise. Therefore, excessive body fat persons should be strength training, strengthening of lean tissue.

3 to lose weight for the purpose of the movement must be in before, it is better to be early, late once, at least three times each week, every 30 minutes at.

4 heat production of drugs can enhance the new supersedes the old. Rate reached 14%, but must be used under the guidance of a doctor.

iPhone 5

iPhone 5 will be the U.S. company's next generation iPhone, Apple, iPhone 4 after news of hot, but Apple has not officially disclosed. Configuration will be upgraded to 800W camera pixels, the system will be ios 5, increasing to 4.0-inch screen. Apple rumors in September 2011 will be released in January -10 iPhone 5. Basic information At 1:00 on June 8, 2010 Apple's Worldwide Developers Conference (WWDC 10) released the iPhone 4 in the country to sell large; the other hand, news of the next generation iPhone 5. Many refer to the earlier reported in iPhone 5 earlier this year on the market, but according to industry sources, Apple plans to deliberately plan the next generation iPhone 5 October this year listed.
 Because Intel has reached an agreement with the acquisition of Infineon Infineon chip wireless communication sector, while the department will operate independently, but sources pointed out, Apple iPhone5 baseband chipset orders has increased from Infineon transferred to Qualcomm body, many industry insiders estimate the acquisition of Infineon Intel wireless business benefits will be greatly reduced.
 According to foreign media reports, Apple's products focus exclusively on the development of U.S. technology blog site 9to5Mac, Apple iphone 5 smart phone has entered the final stage of testing; If nothing else, the new iphone is expected to market in October this year, June 6 at Apple Day at the 2011 annual "Worldwide Developers Conference" (WWDC) conference, the company has not announced a new iPhone, its stock fell 1.6 percent that day.

Symmetric Multi-processor

Usually called dual-CPU system, in fact, symmetric multi-processor system, the most common form, often referred to as two-way symmetric multiprocessing, which in ordinary business, and not many home applications into practical use, but in the professional production, such as 3DMaxStudio, Photoshop and other software applications to get a very good performance, low-cost workstation is set up a good partner. As the user application level, using only a single processor, it has been difficult to meet the needs of practical application, which server vendors have adopted the use of symmetric multi-processing system to resolve this contradiction. In general, SMP scalability of the machine structure is poor, it is difficult to achieve more than 100 multi-processor, the general routine is 8-16, but for most users this is already enough. This machine has the advantage of its use and not very different computer or workstation, programming changes are relatively small, the original computer workstation with programs written in SMP machines, if you want to migrate to use, it is also relatively easy to change . SMP structure of the models available are relatively poor. Because four or eight processors share a single operating system and a memory, once the operating system problems, paralysis of the entire machine is completely lost. And because of this poor scalability of the machine, not easy to protect your investment. However, such models technology is relatively mature, and the corresponding software will be more, so now on the launch of China's domestic market is a lot of this kind of parallel machines. The most common PC server symmetric multi-processing system is typically a 2 -, 4 -, 6 - or 8-way processor. The current UNIX server can support up to 64-CPU system, such as Sun's product Enterprise10000. SMP system is the most critical technologies to better address the multiple processors communicate with each other and coordination problems.

Ten best foods to help you grow muscle

1 Salmon: 6 ounces (170 grams) of salmon provides 34 grams of protein, 4 Ke Mi Jia-3 fatty acids, a lower throat muscles to help repair the health of fat, and it can help suppress cortisol. (Cortisol levels fall, testosterone levels will be gradually increased, to help muscle growth.) Diet rich in omega-3 fatty acids can also make most of the absorption of glucose into muscle rather than into fat.
2 lean beef: many difficult long-abandoned muscle fat people wrongly think that this will increase body fat. However, in the omega-3 fish in synergy, the beef's saturated fat actually helps muscle growth. Too little saturated fat intake be harmful to the testosterone and insulin like growth factor which helps muscle growth hormone levels. Beef is a source of cholesterol, cholesterol is the body's own testosterone synthesis of the main raw material. Of course, beef is also rich in creatine, B vitamins and zinc.
3 eggs: nutritionists have many different ways for a variety of protein foods to promote growth and the ability to score. Almost all eggs in a variety of criteria in at the top. Because they are most likely to be absorbed - the body can easily put them into amino acids, muscle growth material. Whole eggs are also rich in healthy fat, saturated fat and lecithin, which is to help muscle growth. Lines of the sculpture during the yolk may not be too idealistic, but the weight gain in the non-season period, do not forget it.
4 whole milk: If you really want hard long flesh is very heavy, however, do not drink skim, reduced fat milk! To lose weight that is used. 16 ounces of whole milk provides 16 grams of protein and 16 grams of fat. And compared with other foods, milk fat are generally short chain. Relatively short-chain fatty anabolic, prevent muscle break down, and they are less likely than other fats to be stored as body fat. Milk fat may help the body absorb vitamin D, reduce risk of cancer. 60,70 big guy - Arnold, Franco who drink whole milk is not so much by chance.
5 apple juice: The irony is that crazy to go to the gym is to the muscle tear. After you harvest, when your body starts to repair, but over-restored. Go to the gym before the drink 12 - 16 ounces of apple juice can provide 45-60 grams of carbohydrates and quickly give you added energy (because the juice of glucose), and a steady stream of energy (because it also contains fructose). This is to help suppress cortisol and reduce muscle damage, so you can train more groups.
6 white bread: you know this principle - eat less refined carbohydrates, whole grains because they contain cellulose compared to less, less nutrition, and improve insulin levels. In many cases like this. Then, just white bread for the end of your workout really very good. Because you need easily digestible carbohydrates to restore you have to empty the level of muscle glycogen and increase insulin secretion to help muscle growth, and suppression of cortisol after training. 4 white bread can provide about 50 grams of digestible carbohydrates.
7. Pasta: (pasta) increase muscle requires a lot of carbohydrates as raw materials. More importantly, from a fundamental strengthening of carbohydrate metabolism in the efficiency of the protein intake of protein into the muscle to help growth. In other words, no carbohydrates, you will not be well absorbed protein for muscle growth. Cup of cooked pasta about 45 grams of carbohydrates, a difficult person in order to flesh flesh at least the amount of each meal.
8 garlic: a basic calorie, carbohydrate, protein or fat will help the plant how long the meat? The answer is that it will significantly improve your body's hormone levels. Flesh is at the right time to the appropriate intake of nutrients - carbohydrates, protein and fat. But it also requires an appropriate environment to stimulate growth hormone. Animal studies have shown that high intake of garlic and high protein intake makes the testosterone increase, decrease muscle breakdown. This is a growth-promoting state.
9. Yoghurt: Natural yoghurt, low-fat or fat can be either in health food stores. The best option is to contain active "good bacteria" in yogurt. This period of life before the bacteria reach the gastrointestinal tract, help the body maintain a healthy balance. This good bacteria boost the immune system, increase the absorption of nutrients. Another advantage is that calcium, calcium controls muscle contraction, can reduce fat storage.
10 Olive oil: re-gift have to say that olive oil. Studies have shown that: olive oil suppress the body's inflammation, reduce inflammation means better recovery. Olive oil also provides material to improve hormone testosterone, and any lipid, it offers a lot of heat, help the body into the growth-promoting state. It is also rich in healthy fats.
