These recommendations are expected to bring down the increasing incidence of mobile theft in the country.</b><br /> <b>These recommendations were expected to come this month, but Trai came across a new problem as some people can put duplicate International Mobile Equipment Identity (IMEI), which will make it difficult to track the phone.</b><br /> <b>IMEI is a unique 15-digit code that comes with every GSM mobile and helps to uniquely identify the handset. By using the global positioning system (GPS), a mobile operator can track the handset user. This can in turn help government agencies monitor the activities of anti-national elements. It even assists in murder investigations as was the case in the sensational murder of schoolgirl Aarushi Talwar in Noida, on the outskirts of New Delhi. Police was finally able to track the girl’s missing mobile phone through the IMEI number.</b><br /> <b>The telecom operators have suggested to Trai to create a central data base of IMEI numbers of stolen phones which could be shared by service providers. They have also proposed to bring a legislation to prevent cloning of IMEI numbers so that the stolen phones are not re-programmed with duplicate IMEI numbers of existing subscribers without their knowledge.</b><br /> <b>However, companies had asked Trai to make the blocking of the IMEI a chargeable service as there will be additional cost involved to upgrade the network to support the new requirement.</b><br /> <b>Earlier in 2004 Trai had issued a consultation paper in this regard. However, at that time, many service providers had no capability to track or block IMEI.</b><br /> <b>But the situation has changed as in 2008 the telecom department has asked telecos to disconnect mobile phones that do not have IMEI numbers as they could be misused by terrorists or criminals.<br /> Thereafter telecom service providers put the Equipment Identity Regi-ster in their systems so that calls from mobile handsets without IMEI are rejected.</b></div></div></div>

What is the Difference Between NTSC and PAL?

This is caused by a major difference in broadcast formats used by the United States and many other countries. The United States favors a format called NTSC, which is short for National Television Standards Committee, while Europe, Australia and parts of Asia use a competing format called PAL, or Phase Alternating Line.</b></div><div style="text-align: center;"><b>Most of us would not be able to recognize the difference between NTSC and PAL, but then again most of us aren't television broadcast engineers. The differences really start with the electrical power system behind the transmissions. In the United States and other countries, electrical power is generated at 60 hertz, so for technical reasons the NTSC signal is also sent out at 60 'fields' per second. Since most televisions use an interlaced system, this means that 30 lines of the image are sent out, followed by the alternating 30 lines. This line alternation happens so fast that it becomes undetectable, much like a film running through a projector. The result for an NTSC television is 30 frames of a complete image appearing every second.</b></div><div style="text-align: center;"><br /> </div><div style="text-align: center;"><b>Since Europe uses a 50 hertz power supply, the equivalent PAL lines go out at 50 fields per second, or 25 alternating lines. PAL televisions only produce 25 complete frames per second, which can cause some problems with the proper display of motion. Think of it as the 'silent movie effect', in which the actors seem to move a little faster because there are fewer frames showing movement. If a PAL movie is converted to an NTSC tape, 5 extra frames must be added per second or the action might seem jerky. The opposite is true for an NTSC movie converted to PAL. Five frames must be removed per second or the action may seem unnaturally slow.</b></div><b></b><br /> <div style="text-align: center;"><b>Another difference between NTSC and PAL formats is resolution quality. PAL may have fewer frames per second, but it also has more lines than NTSC. PAL television broadcasts contain 625 lines of resolution, compared to NTSC's 525. More lines usually means more visual information, which equals better picture quality and resolution. Whenever an NTSC videotape is converted to PAL, black bars are often used to compensate for the smaller screen aspect, much like letterboxing for widescreen movies.</b></div><b></b><br /> <div style="text-align: center;"><br /> </div><div style="text-align: center;"><b>When the NTSC format was first adopted in 1941, there was little discussion of color transmissions. When the technology for color television arrived, engineers had to create a broadcast method which would still allow owners of monochrome television sets to receive a picture. Color signals on the NTSC format are still not considered ideal by electronics experts. The PAL system, on the other hand, was created after the advent of color broadcasting, so color signals are much truer to the original image.</b></div><b></b><br /> <div style="text-align: center;"><br /> </div><div style="text-align: center;"><b>For most purposes, the difference between NTSC and PAL signals are negligible. A European television set won't work in the United States and an NTSC formatted DVD won't play on a PAL player. But many people own home movies which cannot be viewed on a competing format. For this reason, there are a number of companies which offer conversion kits from NTSC to PAL or PAL to NTSC. Some of these conversion methods can be time-consuming and variable in quality, but others provide an easy way to create a PAL video for a European relative or an NTSC DVD for a Canadian friend. Some electronic media outlets may also provide conversion services for a price.</b></div></div>
