Anywave star v 1 1
1. Planning digital television implementation in Brazil required extensive testing and coverage analysis that cost hundreds of thousands of dollars but still did not perfectly replicate analog coverage, requiring additional power or gap fillers in some areas. 2. A scalable transmitter that can gradually increase power as consumer demand grows is recommended as a more cost effective approach than investing in a large fixed power transmitter before an audience is established. 3. Field tests of mobile digital television reception should also be conducted to test coverage under real conditions.

- 2. 2 • Enormous amountsof money and time spent on planning • Goal was to replicate the analog coverage • Mackenzie University developed a prediction system for reception of ISDBT under real conditions • Coverage also verified by collecting field data of the signal received at dozens of locations. ISDB-T initial implementation • A great deal of testing and planning is typically required before roll out of a new digital standard • In Brazil …
- 3. 3 • The NationalTelecom Agency (ANATEL), established a value of 51 dBmV/m for the field intensity of protected outline in the UHF band in the limit of coverage area. • 51 dBm/V became the target value to replicate analog coverage • Field tests were conducted in Rio de Janeiro to test the robustness of the 1Seg mobile system • By 2012 there were DTV transmissions in 100’s of municipalities across Brazil and coverage was almost at 45.5% of the population ISDB-T initial implementation
- 4. 4 • Hundreds ofthousands of dollars (Reals) was spent on coverage analysis ISDB-T initial implementation • Most of the coverage tests were accurate, but even with all the money and time spent • There were still lots of installations that were not getting the coverage as planned and further power increases were required or on-channel gap fillers were needed. • In some cases the transmitters were too big • And in other cases the transmitter power was not sufficient
- 5. 5 • Quantity ofviewers initially can be small • DTV implementation in most countries was slower than expected… typically because of…. • No Mandated Analog Switch Off Date • Prices of new DTV sets and set top boxes • Failure to understand the new technology • No realization of the benefits ISDB-T initial implementation So why invest so much now when there are no consumers (revenue)?
- 6. 6 • Why Investfirst? • This is NOT a Chicken and Egg situation • TV stations must go on air to gather interest. You cannot expect consumers to invest in digital TV receivers when there are not signals to receive. • But it is also important to invest wisely ISDB-T initial implementation Why not Invest only the amount you need to and grow with consumers
- 7. 7 • Typical transmittersizes (TPO’s) vary from ISDB-T initial implementation 100W 5000W • Providing ERP’s of 1kW to 100kW • Typical costs of Transmitters can vary from 20K USD to 250K USD to

- 19. 19 • Conclusion • AsTPO increases from 500W to 5kW …some coverage increases • Which relates to better indoor and mobile coverage • But strive for maximum coverage when the viewers are not there • A compromise solution is the • SCALABLE TRANSMITTER with an ADAPTIVE RACK ISDB-T initial implementation
- 20. 20 • What isa SCALABLE TRANSMITTER? One that can be • Quickly • Easily • and cost effectively increased in power • 500W => 2500W • 2500W => 5000W or more • With a SCALABLE transmitter… the typical cost to upgrade in power is less than 10 % more than to purchase the original power.

- 33. 33 • Cost ofa SCALABLE (STAR) Transmitter Example: • 500W STAR = $30,000 ISDB-T initial implementation • Price to upgrade 500W STAR to a 5kW STAR = $182,000 • Difference is only 6% (or $12,000) • Difference in investment = $170,000 • Over three years at 5% interest = $26,796. • Profit of (26796 – 12000) = $14,796 • 5kW Typical Price = $200,000
- 34. 34 • A lotof testing and planning will be needed to roll out of ISDB-T • Many field tests should be conducted in large and small cities in urban and rural areas • 1Seg mobile system testing will be required • Public awareness is key to the success; this will not happen overnight • Analog shut down in some cities should be planned • And the ASO should be adhered to • More cities should soon thereafter shut off analog • Entire country should plan ASO carefully Conclusion
- 35. 35 • Being ableto make a small investment today, and grow with the population, grow with the take up and acceptance will allow TV stations to invest WISELY, and PRACTICALLY. • A scalable transmitter is the best investment in order not to make a large financial investment mistake • Scalable Transmitter and Adaptive Rack (STAR) is offered specifically to the Philippines at very competitive prices Conclusion
