Sony movies on Internet connected TVs & Blu-ray players

Declining DVD sales and lackluster box-office performances are driving Hollywood studios and Consumer Electronics manufacturers to come up with new ways to increase their revenue streams. As this BusinessWeek's article and NY Times article report, Sony is experimenting with making some movies available through it's Internet ready Bravia TVs and Blu-ray players just before their DVD release. This new window, called as Home theatrical window is spaced between movie's theatrical release and it's DVD release so that,  interests of theatre owners and DVD retailers are equally served . Sony, with it's unique position as Hardware manufacturer and Movie studio owner, is trying to convince other Hollywood studios and content providers to join this experiment.

Even though HDTV and Blu-ray technology adoption is slow, there seems to be a section of viewers who are willing to pay a premium for watching movies on their big TV screens well before it's DVD release schedule. The quality of a typical internet streaming movie may be comparable to DVD quality but it doesn't match with Blu-ray quality. As Blu-ray technology becomes more mainstream, the popularity of this offering from Sony  is going to depend on the quality of the online stream and how it is priced compared to DVDs.

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:
