No. Technicolor is an analog film process; it has nothing to do with digital imaging and is several decades older.
When is analog signaling going to be turned off?
Analog signals of US television programming will end February 19, 2009. The formatting will change to digital, which will require a cable box to decode the programming.
Can you play a DAT tape on a normal cassette player?
No you cannot. A regular cassette player uses analog technology to pick up, analyse, convert and play analog sounds. DAT stands for Digital Audio Tape. DAT format is digital and uses 1s and 0s like a computer hard drive. The analog cassette will not be able to get any meaningful information from a DAT tape. So i need to buy a special DAT player to play DAT's?
What is digital projection?
Digital projection is using digital means to project an image, as opposed to analog film. Different technologies are available for consumer digital projection (LCD, DLP) each with their own separate advantages and disadvantages. Many movie theaters now are equipped with a 4K digital cinema projector, which in many cases is far superior, but similar to a consumer level projector.
Do you need antenna to receive digital signals on LCD TV the TV has a built in HDTuner Can we use indoor antenna?
All TVs including new ATSC Digital ones use the same frequencies as older NTSC Analog sets. An amplified antenna is recommended because there is a threshold where a weak analog signal will be visible (with considerable static) but a digital tuner will not have sufficient strength to display a digital (no noise or static) picture. Outdoor roof Antennas work great as well, you don't need an HDTV antenna, discount stores should have one for around $30.
