As the cost of Digital Video Recorders (DVRs) continues to fall, DVRs are now becoming a “must have” item in many homes. DVR technology enables viewers to record live TV, play back, pause and rewind live broadcasts and store many hours of programming. A recent global research study showed that the owners of DVRs overwhelmingly agreed that their enjoyment of watching TV was significantly enhanced by having a DVR and that it was the second most important household item, after the mobile phone.
While measuring television signal in Cable, Satellite or terrestrial, many complicated factors and parameters coome in play. However, if the measuring instrument is efficient and good, it relieves the engineer of remembering all the parameters and taking them in consideration while judging a signal quality. It simply
A couple of years back, STBs were associated with CAS under a tough regulatory regime imposed by the government. Doordarshan started Free to Air service (DD Direct,) which made TV penetrations among remote villages a dream come true. The picture quality, however, distributed over analog cable network has been sub-par. Today, however, STB is increasingly seen as a technology easily deployed in living rooms. It is fuelling consumer appetite for ‘high-quality’ digital picture displayed on big screen TVs including fast growing LCD TV segment. Already, there are five DTH operators and the 6th one is about to launch service, along side of a host of cable operators
The first radiotelephone service was introduced in the US at the end of the 1940s, and was meant to connect mobile users in cars to the public fixed network. In the 1960s, a new system launched by Bell Systems, called Improved Mobile Telephone Service” (IMTS), brought many improvements like direct dialing and higher bandwidth.
How can you simplify digital cable deployment without breaking the bank? Leaving aside the fact that some of our banks seem to be broken already, few would deny that digital cable has been slow to develop in India, as while the market is incredibly dynamic it is also fragmented. This often requires a highly complex planning process when it comes to rollout. “Not only does India have a huge number of cable systems ranging from large MSOs to many local operators, but it also has to face the major obstacle of signal piracy,” says Jeremy Thorp, CEO at Latens, the UK-based software Conditional Access System (CAS) and middleware vendor for digital Pay TV. Then there’s the challenging prospect of competing head-to-head with the nation's new fleet of satellite TV providers with a service that offers better quality of viewing, and most importantly at an attractive price. In addition, the Indian government has recently mandated the adoption of a CAS (Conditional Access System) for cable operators, which many end users and operators believe may considerably raise the cost of pay TV service delivery. With such a downward pressure on finances, it’s not altogether surprising to see the emergence of budget revenue protection systems that seem to be almost too good to be true. But as ever, you get what you pay for, Thorp warns.
The broadcast industry today is in the throes of change. Broadcasters are faced with the need to transition from standard- to high-definition services and, as they begin to do so, they are finding themselves faced with a host of new challenges. Not least of these challenges is the need to move from their traditional tape-based infrastructures to today’s file-based workflow.
As the technology is going ahead with a rocketing speed, India too is pacing with it and have shaken the world to get noticed. Due to rapid development most companies of the world are queuing up to please the Indian consumer as well raise the standard of life. And that is why, perhaps, more and more companies are introducing their upgraded products. Till now, most Indian companies had been using their S (satellite) technology, which specifies the use of QPSK modulation along with various tools for channel coding and error correction.
One of the great divides of our time is between classical media sociologists and mathematics. Sociologists offer us 'futurology' based on current social divisions and statistical analysis. Technology evolution is often seen as given out by the 'hand of providence', in all its mystery. The media has, at any given time, an 'agenda' set by conspiracies of human beings. These theories are wrong. They may be wishful thinking for a simple life, but they are not the truth.
WiMAX, or Worldwide Interoperability for Microwave Access, is a wireless telecommunications technology capable of providing data over long distances in a variety of ways, from point-to-point links to offering full mobile cellular access. It is also known as wireless broadband and fits between wireless LANs, such as 802.11, and wireless WANs (wide-area networks), such as the cellular networks.
The broadcast industry in India is gearing up for the government’s push toward mandatory conditional access (content security) for the cable TV industry. Conax is aware that piracy in terms of illegal content redistribution is an increasing source of revenue loss for broadcasters in India. To respond to this challenge, leading content security provider Conax is working together with customers and partners in India to combat this form of piracy and build a solid defence against potential pirates.
The Telecom Regulatory Authority of India has sent its recommendations to the Ministry of Information & Broadcasting on certain issues relating to Direct to Home (DTH) service last month. A consultation process was earlier initiated by the Authority by issue of a Consultation Paper on “Issues Relating to DTH” on March 2, 2007. The consultation paper covered interconnection issues, quality of service issues and other regulatory issues relating to DTH services. The Authority subsequently held an open house discussion in Bhubaneswar on May 18, 2007 on the subject. The Ministry of Information and Broadcasting had also sought recommendations of the Authority on Technical Interoperability of Set-top Boxes (STB) as well as to examine the possibility of allowing DTH operators to provide signals to cable operators in KU-Band.
Last month, TRAI sent their recommendations on HITS to the Ministry of Information and Broadcasting. Perhaps, the pace of reaching these recommendations was made the shortest, just two months and twenty days for reasons best known to TRAI. Sending these recommendations in such a hurry, making HITS as another competing technology baffles many experts in the Industry. The very purpose of HITS as its name suggests, is to act as a satellite based head-end to the Cable Operators on the ground rather than be a stand alone technology for television delivery that needs to have a level playing field with DTH, as suggested by TRAI.
IPTV is a product of convergence on the back plane. The same Digital Content seamlessly transcends different access Networks be it Telecom Network or Cable Network. In IPTV environ IP content in packets are delivered to different screen be it TV, PC or mobile devices with the help of a gateway / STB. Thus, we see a total convergence scenario in the back plane and the front end, which is the STB/ gateway which may be connected to any reception device.
