Is Google TV The Wave Of The Future


Many over-the-air TV channels across the U.S. will be changing frequencies to help open up airwaves for new high-speed wireless services. The actual channel number on your TV will not change. After the TV is rescanned, it will be the same as before.




Is Google TV the Wave of the Future



Is it the future of TV? In a sense, yes. Sky Glass is a shining example of how you can design an interface that pulls together apps, streaming services and broadcast channels without the menus becoming one big, slow, confusing mess, and we hope others follow its lead.


But this seemingly simple approach quickly becomes cumbersome as you build out your smart home. Some devices, such as the Schlage Encode smart lock, work with some systems (Alexa and Google Home) but not others. Not all ecosystems offer the same types of devices. For example, large appliances like washers and ovens are supported by Alexa, Google Home, and SmartThings but not Apple Home. And each subsequent device you purchase makes it more expensive and prohibitive if you decide to change ecosystems in the future.


Our brains are not wired to contend with the pace of technological change: These respondents said the rising speed, reach and efficiencies of the internet and emerging online applications will magnify these human tendencies and that technology-based solutions will not be able to overcome them. They predicted a future information landscape in which fake information crowds out reliable information. Some even foresaw a world in which widespread information scams and mass manipulation cause broad swathes of public to simply give up on being informed participants in civic life.


It is also human nature to come together and fix problems: The hopeful experts in this canvassing took the view that people have always adapted to change and that this current wave of challenges will also be overcome. They noted that misinformation and bad actors have always existed but have eventually been marginalized by smart people and processes. They expect well-meaning actors will work together to find ways to enhance the information environment. They also believe better information literacy among citizens will enable people to judge the veracity of material content and eventually raise the tone of discourse.


A number of these experts said solutions such as tagging, flagging or other labeling of questionable content will continue to expand and be of further use in the future in tackling the propagation of misinformation


The state of 5G in the US is pretty rough right now. For 5G to offer an experience that's noticeably better than 4G, it needs broad, dedicated channels, ideally 50MHz or wider. For 5G to cover entire cities, it needs to be on a frequency below about 6GHz, so it can get decent range from towers. Right now, AT&T and Verizon aren't using any airwaves that fit these bills. Verizon may be able to pull something together using the new CBRS airwaves just below the C-band, but the jury's still out on that. So by and large, AT&T and Verizon are delivering 5G that's either no faster than LTE would be on the same frequencies or has poor range.


C-band can fix this. The government auctioned off 280MHz of airwaves in the main C-band, and another 100MHz in 3.45, that are likely to go up to about a half-mile from each tower, so plenty of bandwidth for several different wireless carriers to have solid 5G using mostly existing cell sites.


Our first tests of Verizon's C-band show about a 0.37-mile range in very dense Queens, NY. That seems to be limited not by the power of the airwaves, though, but by Verizon not wanting its cell sites to interfere with each other. So half a mile in much of the country still feels good to me.


The main C-band frequencies from 3.7-4.2GHz are rolling out in two chunks. The first 100MHz are now available in around 50 major markets across the US, covering about 60% of the US population. Verizon and AT&T split those "A block" airwaves 60/40. So Verizon will be just above, and AT&T just under, the 50MHz rule of thumb I've been using for real 5G differentiation.


The above brings me back to the subject line of this article. Yes! Virtual Assisting is the wave of the future. Think about it. (No need to use too much brainpower though - because it's almost a no-brainer). If you are a business owner or manager, think of this. More than physically seeing the people that work for you, what do you want? You want RESULTS, right? You want to make more MONEY. Right now, with your assistant or other administrative type staff members, you are paying for office space, you are paying for benefits packages for them, you are buying their office supplies and giving them a set hourly wage or salary for 8-hour shifts, 5 days a week (normally), etc. What if they produced more for you in less time, and you didn't have to pay for all the aforementioned things to boot? Remote work is booming! The Virtual Assistance (VA) world is a real thing and it will be bigger and bigger as we move into the future. There will be newbies out there jumping on the bandwagon to gain a better work/life balance and complete tasks on their time with flexible work schedules. Thousands daily, I am sure. Why not find a VA to support you now? Don't know where to look? I can help you out. No, seriously, I'm a one-stop-shop here. All-things administrative and virtual.


The 100-year anniversary of the 1918 pandemic and the 10-year anniversary of the 2009 H1N1 pandemic are milestones that provide an opportunity to reflect on the groundbreaking work that led to the discovery, sequencing and reconstruction of the 1918 pandemic flu virus. This collaborative effort advanced understanding of the deadliest flu pandemic in modern history and has helped the global public health community prepare for contemporary pandemics, such as 2009 H1N1, as well as future pandemic threats.


All of these issues show that more work needs to be done, both here in the United States and internationally, to prepare for the next pandemic. On May 7, 2018, The Rollins School of Public Health at Emory University in partnership with the U.S. Centers for Disease Control and Prevention, hosted a one-day symposium on the 100-year anniversary of the 1918 influenza pandemic. The event involved experts from government and academia discussing current pandemic threats and the future of pandemic preparedness, influenza prevention and control. U.S. and global influenza experts who attended the meeting agreed that we still face great challenges to prepare for future flu pandemics, but part of the solution is recognizing these challenges and working together with the rest of the world to address them.


In this review paper, we compare the performance of mLEDs, OLEDs and μLEDs according to the abovementioned criteria. In particular, we evaluate the power consumption and ACR of each display in depth and systematically compare the dynamic range, MPRT, and adaptability to flexible and transparent displays. The pros and cons of mLED, μLED, and OLED displays are analysed, and their future perspectives are discussed.


For the CC-type mLED/μLED emissive displays, the colour gamut is jointly determined by the blue LED chip and the green and red quantum dots. The narrow FWHM and high central wavelength tunability of QDs can theoretically enable >97% Rec. 202035, and 93.1% has been experimentally demonstrated101. In this CC emissive display, additional attention should be paid to blue light leakage. The QDCF should be thick enough to effectively convert the blue light to red and green44,102, and an additional absorptive CF44,45 or DBR46 is needed to clean up the unconverted blue light and to minimize ambient excitations. As discussed above, the current-sensitive spectrum of inorganic mLEDs/μLEDs causes a colour shift on the blue subpixels under PAM so that PWM is still a preferred approach. In comparison, green and red quantum dots exhibit stable spectral emission profiles even though the wavelength and intensity of blue pumping light fluctuate. In addition, the colour shift may come from the angular emission profile mismatch between the blue LED and green/red quantum dots. To address this issue, scattering particles are added to the blue subpixels in the CC film to generate the same Lambertian angular profile as the green/red subpixels.


Smart wristbands have viewing conditions similar to smartphones. The unique technical challenge is flexibility. To fulfil this requirement, first, the light source should better be 2D arrayed, opening the door for emissive displays and mLED-LCDs. Second, the light source requires good off-axis performance. As discussed in the HDR section, the colour shift can be suppressed by various approaches. The main off-angle challenge comes from the quarter-wave plate in the CP. Therefore, CP-free small-aperture RGB-type and flexible QDCF112-laminated CC-type μLED emissive displays have the least physical limitations on flexibility and sunlight readability. On the other hand, the gamma shift on nonemissive LCDs has been well compensated6,38,39,40, and the integrated linear polarizer enhances the ACR. Researchers have developed organic TFTs for plastic substrates and flexible LCDs113. The so-called OLCDs have lower manufacturing costs and easier scalability for large panel sizes than do flexible OLED displays. Overall, OLEDs are the most mature flexible display technology, except their ACR is limited. New OLED materials with high EQE and long lifetimes are under active development14. The commercialization of flexible mLED-LCDs depends more on market strategies instead of technical challenges. Flexible μLED emissive displays are in the prototyping stage19,29. The CP-free small-aperture μLED is theoretically the best candidate.


Mini and micro light-emitting diodes (LEDs) could move to the centre-stage of display screen technologies once they mature. Shin-Tson Wu of the University of Central Florida and colleagues analysed the pros, cons, and future prospects of the latest display screen technologies, especially for use in smartphones, smart watches, virtual and augmented reality, and heads-up vehicle displays. These applications require bright, flexible, transparent, and power-efficient displays. The currently dominant liquid crystal displays (LCDs) require a backlight unit, dictating their shape and flexibility. LCDs with a backlight unit made from mini LEDs are becoming rapid contenders to the conventional technology. So are displays using organic light-emitting diodes, but these are limited in their brightness and lifespans. Emissive displays made from mini and micro-LEDs show huge potential once manufacturing costs can be brought down.
