A cable set-top box may one day disappear? U.S. startup Netzyn is developing a software to create a virtual set-top box for execution in the cloud; the software, called NzOS, can deliver streaming media services from the cloud to a variety of applications, including Android, Linux, and Windows platform devices. TV operators can use the software to shrink set-top boxes to U-disk sizes, and even integrate them into TV sets.

The issue of Network Function Virtualization (NFV) began to attract the attention of major European network operators about two years ago, trying to find a way to solve the problem of overloaded network traffic due to the explosion of mobile data. So far, these companies have developed a series of technical specifications to transfer network functions to software that can be executed on x86 servers, but Christos Kolias, a senior fellow at the European telecom giant Orang’s Silicon Valley Lab, said that most of the relevant results are still Not yet out of the laboratory or still field testing, in addition there are still many related technical specifications development work to be completed.
"I hope that the work can be completed in 2 to 3 years, so that the relevant suppliers can say that their products are in compliance with the NFV specifications; however, we do not have a certification plan;" Kolias pointed out: "There are still many changes, but we have achieved remarkable results. The industry has always been very supportive.†Telecom operators and their suppliers including ATT, Alcatel-Lucent, and Orange, ZTE are all participating in this seminar, as well as CableLabs, a research and development consortium of cable companies in the United States; In these days, the line between TV, Internet and mobile network service providers has become increasingly blurred.

The previously mentioned Netzyn is actually a news item published by ARM. The latter used it as one of the examples of the company's response to the NFV trend; Netzyn's software demonstration was performed using an Applied Micro X-Gene processor server using the ARM core. There is also a micro server with Samsung Exynos 5422 processor. Karthik Ranjan, Director of ARM Carrier Accounts, said: "Transferring set-top box functionality from a stand-alone box to a remote server that communicates directly with the TV can significantly reduce costs, energy, and materials without compromising the performance of the user interface (UI). ""
Ranjan emphasized that the virtual set-top box: "Enables operators to provide new services on TV faster and increase the average revenue per user. It can also lower their overall operating expenses through cloud computing and low-latency networks." "The presentation of Netzyn products is one of dozens of practical examples of NFV specifications developed by the working groups of the European Telecom Standards Institute (ETSI).

Set-top box will disappear?
Intel is also an early supporter of NFV, even before the development of ETSI specifications, the main reason is optimistic about the relevant solutions to help sales of x86 processors; ARM before the publication of Netzyn news in the NFV field is relatively low-key, but the company and the number Home processor SoC partners all posted relevant news at this seminar. Like Intel, Broadcom was active in the NFV and software-defined networking areas earlier and also delivered many speeches at the seminar.

The development of NFV and software-defined network related solutions may increase the competition between the x86 and ARM processor camps, because operators will choose to perform services on x86 server ASICs or ARM core commercial SoCs, but operators also It said that they do not think that there will be a large number of telecom services from the current ASICs and commercial SoCs of telecommunications equipment such as switches and routers.
Orange's Kolias said: "That doesn't seem like hardware is going to disappear, it's more like a shift; for example, we're seeing some hardware-based devices that specialize in providing certain NFV features, such as security applications, we might need something like That kind of thing."

Lock Motor product introduction:
Intelligent Lock Motor, also known as electronic locks, the product effectively combines the advantages of traditional electronic locks and electromagnetic lock overcame the electric lock too much noise, electromagnetic lock power shortage and the development of new products, and spiritual compared with electric control lock and magnetic locks, lock its performance more perfect, more obvious advantages.
Functions: it is widely used in various intelligent locks, such as Shared bicycle lock, fingerprint lock, glass lock, safe lock, hotel lock, family lock, inductive smart lock, etc
Features:Lock motor is based on micro precision reducer development, small intelligent micro precision reducer can do 10 mm in diameter, is widely used in safe, locks, smart locks, sensor intelligent lock;
This kind of motor has the characteristics of low noise, low energy consumption, small volume, light quality, high precision, large torque and durability
Method of use: the best stable in horizontal plane, installed on the lock motor output shaft parts, cannot use a hammer to knock, knock prone to press into the dc lock motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
lock motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a lock motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
lock motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of lock motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you
Looking forward to your inquiry. Welcome to our factory.
