BART expands wireless access

BART (Bay Area Rapid Transit) has started providing      wireless connections to all passengers on it's trains  underground. This is a good news for thousands of bay area commuters who take underground tube daily to work. Wireless service underground especially comes handy in situations like technical glitches or natural disasters.  Five of the Bay Area's six wireless providers have agreed to use the system. But, from initial reports, cellular signal seems to be spotty. Hopefully the coverage would improve in coming days. Service availability schedule below:

Ustream broadcast application for iPhone






Ustream is a web streaming service that lets people broadcast and watch live events online. Although it is not the most popular web streaming service, educational and entertainment community heavily uses the website to broadcast course work and concerts. Educational community seem to especially embrace Ustream for distant learning as it gives faculty free, easy-to-use options to conduct coursework that allow student interact through chat.

Ustream iPhone application lets users record videos to the smart phone or go-live on Ustream's website. Local and live recording can be set to 320x240 or 176x144 resolution. You can play the uploaded videos on your computer, iPhone or share the video on Facebook, Twitter and YouTube.

My Apple Experience!!


I wasn't a fan of Apple products for a long time. My first introduction to Apple products was in early 2005 when my employer gave me a Powerbook and I bought an iPod shuffle. They were both nice looking products and worked just fine, but I wasn't terribly impressed.

Those days I used work on my powerbook with Mac OS X Tiger at home and had a light weight 12" dell for work. As fas as the OS goes, I didn't find Mac OS X to be any more powerful or stable or easy to use than my XP. I found myself more at home with XP than with OS X. Lack of the range of software was a big negative and even for the apps that were available, the Mac versions are limited in feature set compared to my PC. Yahoo messenger didn't have video chat, websites with telugu scripts didn't work with firefox or safari neither does Yahoo music and telugu radio, iphoto couldn't handle a gigabyte of photos without freezing. Many little problems add up and made the experience less than ideal. I liked the hardware very much, a lot of thought is put into the placement of the keys on the keyboard and some special keys that makes life easier. The look of the machine was pretty cool and the coolness factor is pretty much evident. I carried it around to coffee shops, libraries, friends places etc...

And iPod shuffle, I just wanted to check out what the fuss about an iPod was all about and I bought the cheapest one I could get. Not the magic I was expecting. No display, no FM, its just a dumb device. The sleekness will only make u happy when u buy, after all its the utility. For the price $129, it was a rip off. May be if I went with regular iPod, I might have had a different experience. But Hey... the shuffles were selling as many as the regulars. Also, I never had a music player before shuffle and I never understood how can some one spend so much money on a device that does only one thing, play music.

With my experience with powerbook and shuffle, I couldn't understand what is so great about Apple products that people around me love so much and are willing to pay a hefty premium, I was certain that it is just bought by young and hip people to feel cool and so a great but mere marketing win by Apple.

When a phone from Apple is rumored a couple of years before it was released, I vehemently argued with my friend that the mobile phone market is not that easy to crack. Some of the most innovative companies like Nokia, Motorola, Sony, Microsoft have been in the market for years. I said it is impossible for Apple to beat them at their own game. I told him this time it would be different and apple is going to get smacked. My friend said he don't know how, but Apple will come up with something new that can compete with other phones on the market.

When MS was coming in with Zune and its marketing muscle, I said MS will neutralize iPods halo as well. My friend was sure that Apple would continue to innovate on iPod, and MS will be left chasing iPods tail.

I suspected he joined the cult of Apple and cannot see the truth. Not really. His prophecy came true.

Apple announced iPhone. I was on road for a conference and checked out Jobs key note after work. I called my friend and said I would buy it today if they sell it for $500 unlocked and if it is available on Verizon, since my employer pays for the service. I was so impressed with the device I was willing to shell out 500 bucks with out seeing it. But I was disappointed to learn that it is going to be available only on ATT and only 6 months later. Months followed with discussions on lack of keyboard, lack of features, blah blah... When the crazy rush subsided after it was released, I went to an Apple store and was disappointed with the phone as it took me less than two minutes to run out of things to check. I wrote about how expensive it is for the limited stuff to do and declared Apple just sells cool overpriced stuff for stupid kids.

Then things changed. I became a Product Manager. I had to shop for phones as I moved to my new job. I checked out Blackberrys, WinMos, Nokias and what not. I suddenly realized how inelegant and antiquated the rest of the phones and their interfaces are compared to iPhone. I could not believe how stuck the biggies are. There is nothing in those phones that says 'User Experience'. But was sure that Nokia will slam a dozen phones at Apple and drown it. Then, Apple announced App Store. Applications treated like MP3 songs? How did they even come up with that? That made me relate to the MP3 world before iPod and iTunes and why they were such a hit with music lovers. As I continued working on my product as a Product Manager trying to decide what to build and how to build, I started to truly understand the magic of Apple. The fact that after all these years, all these big wigs are still chasing iPod's and iPhone's tails.

I was not around to understand the impact when the first Mac was released or when the first iMac, the first iPod or iTunes were released. But I bet the excitement and WOW factor would have been as much as I have felt when I first saw and read about iPhone and about App store in iTunes. It is truly incredible how Jobs remade so many industries over and over.

Google Android Phones

After missing the opportunity to team up with Apple on iPhone more than 2 years ago, Verizon is betting big this time with the introduction of a slew of phones running on Google's Android platform.

Motorola's Droid (available on Nov 06) is the first touch-screen smartphone to use Google's Android version 2.0. Droid's features include sync to Exchange right out of the box so that you can check your work emails and download contacts and calendar. It also syncs your contacts with Facebook. Droid has a 5-megapixel camera with built in flash. Like other Android based phones, it can run multiple programs at once. The Google maps application in Droid can turn the smartphone into a GPS device providing turn-by-turn directions.

However, compared to iPhone, Droid's OS and look-and-feel is not refined. It does not support true multi-touch and it's application foot print is not as big as that of iPhone. Android's inability to use more than 256MB of apps is another drawback. But, better wireless coverage from Verizon and positive reviews by technology critics would make this smartphone a top shopping item for people looking for a mobile this holiday season.

According to Google, 18 mobile phones will be using Android platform by the end of 2009. Below is a partial list of phones available in North America:

Phone

Android Version
HTC Dream (T-Mobile G1)

HTC Magic (T-Mobile myTouch 3G)

Movies on USB drives


Kingston today announced that it has teamed up with Paramount Pictures to deliver full-length movies on it's flash memory products. The company announced that the movie offerings on USB and SD cards will help reach wider audience as more and more movies are viewed on computers and other portable devices.

Owning movies on a USB or SD drive falls somewhere between owning a physical disc and owning/renting/streaming digital content in terms of consumer's perception about owning something that they buy. Nowadays almost every computer comes with a DVD drive and not all portable devices support SD cards. This is going to narrow down the prospective audience for this new offering. Also, as people are moving towards Blu-ray high definition content, it would be difficult to get people buy this DVD quality movie offering in USB/SD cards.

 As more and more content is made available in digital format, it remains to be seen whether this kind of offering is going to help Hollywood studios that are already affected by dwindling DVD/CD sales.

Calibrating your HDTV picture

If you decide to play with your HDTV factory default settings and calibrate them to better suit your viewing environment, there are couple of options available out there. Depending on how much perfection you are seeking in picture quality and how much money and time you want to spend, these options range from using freely available calibration software, to buying a calibration disc, to using the services of a professional calibration technician. While individual viewing preferences may vary, the free/low cost calibration software would definitely help improve the picture quality. For even better results, you can go for a professional calibration.

In either case, knowing a bit about the picture related terminology helps you make a better decision. Picture quality can be improved by adjusting TV's Brightness, Contrast, Sharpness, Color, Backlight and Tint. Advanced options like Color Tone, Dynamic Contrast, Gamma, White Balance, Edge Enhancement and Flesh Tone can be used to further improve the quality. Note that different TV manufacturers may use different terminology to refer to these advanced options. Table below lists color settings for a typical HDTV:

Parameter

Value
Backlight
7
Contrast
95
Brightness
45
Sharpness
6
Color
50
Tint (G/R)
G50/R50

Below is a list of popular disc based calibration software tools:
* THX optimizer (available free on every THX certified DVD, Blu-ray disc)
* Digital Video Essentials
* Sound & Vision Home Theater Tune-up
* Imaging Science Foundation calibration wizard
* Avia Guide to Home Theater

Blu-ray Vs Broadcast HD

Like everybody else, I am starting to enjoy the amazing and crisp video quality of Blu-ray movies compared to Broadcast HD or DVD movies. But, while watching Broadcast HD shows or movies, there are occasions that make my eyes believe that Broadcast HD video quality is as good as Blu-ray, if not superior (especially with animated movies). It is not easy to compare these two video qualities without taking into consideration factors like Transmission mode, Compression, Bitrate, Load on Broadcast provider's network and type of the content and your TV settings.

Compression: Blu-ray discs use 1080p maximum and MPEG-4 compression which results in higher possible bandwidth. Broadcast HD transmissions are 1080i maximum and use MPEG-2 compression which results in lower possible bandwidth.

Bitrate: Blu-ray technology transmits the content at 40 Mbps (total 48 Mbps for video and audio). Broadcast HD transmits at around 20 Mbps. Lower bitrate for broadcast HD means squeezing the content resulting in loss of details.

Network Load: Broadcast HD quality is affected by network load which depends on number of subscribers availing the service at a particular time and other infrastructure related factors.

Content Type: CGI rich animated movies lose less details in broadcast transmission compared to a normal movie. This, sometimes, results in a Blu-ray quality comparable movie experience from broadcast HD.

TV Settings: TV Settings play a big role in viewing experience. Factory defaults are not always the ideal settings for a typical home viewing environment. By optimizing your HDTV settings, you can enjoy better picture quality for both Blu-ray movies and broadcast HD content.

All things considered, Blu-ray content has superior quality over broadcast HD content.

Netflix one step closer to conquer your living room

Over the weekend, Netflix announced that PS3 owners soon will be able to watch Netflix's streaming content. This is an interesting announcement from Netflix, considering the fact that their streaming service is already available on XBox and they are using Silverlight technology from Microsoft in their players. PS3 now joins the long list of devices that support Netflix's streaming: Roku player, Tivo player, XBox 360, LG/Samsung/Insignia Blu-ray players, LG/Sony/Vizio HDTVs, LG/Samsung Blu-ray Home Theatre Systems, Windows and Mac computers. This will help Netflix get more gaming customers subscribe to their service with the possibility of starting their own game rental service to PS3/XBox community (Beware, Gamefly!).

Next step for Netflix would be to provide the streaming service to Mobile users. An iPhone app that can start playing the show that is paused before. Also, the ability to edit 'instant queue' from the Mobile app or TV remote. I see three hurdles associated with this Netflix iPhone/Mobile app. i) iPhone compatible player technology [either Microsoft should make Silverlight iPhone/Mobile ready or Netflix should abandon her bedfellow for a while and go with different player technology for Mobiles ii) Bandwidth - While you may enjoy the streaming content on a 3G mobile, content streaming to 2.5G mobiles will not yield desired results. iii) Apple's reluctance to host such an app, as it would cut into it's iTunes service.


As the ever increasing customer base demands more quality, Netflix would have to improve it's streaming service by providing more 'new' movies to the "watch now" list and improving the stream quality. Improving stream quality is costly and time consuming. The quality of a typical streaming content falls between that of DVD and broadcast HD content (depending on your internet speed). Also, at present, streaming does not support multi-channel audio (just stereo) or closed captioning. The devices that come pre-installed with Netflix streaming service are capable of 1080p. So, Netflix's should aim at providing atleast broadcast HD quality content through the streaming service in order to keep the new customers coming to them.
