Our primary directive at CDTV is to encourage you to learn as much as possible about HDTV. One of the best ways is to read and understand as much as you can from the CDTV consumer web site. Understanding what is happening to the consumer/TV viewer will go a long way to understanding what is driving broadcasters
Unless you’ve been filming in the Himalayas for the past 5 years, you must have seen that HDTV sets are pretty much dominating the electronics stores and have been doing so for the past few years. In Canada the trend has been to bigger, better TV sets, mostly widescreen (16:9) units. In fact, well over 50% of Sony’s TV sales in Canada are widescreen HD sets. This trend has been coming on strong for over 5 years, fueled by new, lower priced and advanced technologies such as DLP, and significant price drops in LCD and plasma displays This trend is showing no signs of slowing down, and indicates that there is a lrge embedded base of consumers ready for HD production.
The Broadcast world is changing and so must you! …HD is the new world standard!
The broadcast world is changing rapidly andthere is no going back. When the ATSC committee in the US set the new standard for digital HD broadcasting in 1999, it was only a matter of time before a complete transition happened. While one might think of this as a slow migration, it’s quite an impressive transition when you consider the many changes that have had to happen in a short time to get us where we are today.
1) Broadcast and production formats approved
Add to this the fact that the major transition to HD has already happened to broadcasters in the United States and one can clearly see that a complete transition or migration is not far away. In fact, the American FCC has established a drop-dead date of April 2009 for analogue (NTSC) broadcasts.
While technical issues of transmitting every channel in HD still remain, one thing remains constant: HD is very quickly becoming the new and real professional broadcast standard. Canadian Producers must be aware of this, whether or not your broadcaster asks for it today.
