Besides our HD World, there is an external factor to push the "HD" concept. It is Digital Broadcasting. However, be reminded that they are 2 different concepts:
- High Definition (HD) : Digital broadcasts with either 1,080 active scan lines in interlaced format—called "1,080i"— or 720 lines in progressive format—called"720p" as defined by the Advanced Television Systems Committee. (from: http://www.learningcenter.sony.us)
- Digital Broadcast : To send a digital stream of information to your television set, a TV station takes tiny slices of the video image, assigns a numeric value to describe each slice, and mathematically encodes those values into equations... (from: http://www.learningcenter.sony.us) In contrast of analog broadcasting, digital broadcast provide better transmittion, because the structure of digital signal is simple (0 or 1) and it is basically strength. (It is very technical and you may find such information in google)
In future, we can enjoy the HD Digital Broadcast TV in Hong Kong. It is relatively late comparing to Japan, US, Europe and China. :(
The format and broadcasting information is not released in HK yet, so how come can we see "HD Ready" in the TV market?
It is not a trick. Since we don't have confirmed information from government, we cannot say that we offer "HDTV". We only can offer "HD-Ready" TVs
- HDTV Ready : Sony's term for a set that doesn't have a built-in digital tuner, but can show high definition broadcasts in true high-definition resolution... To receive digital signals for the sets, however, consumers have to buy a separate HD receiver box (ClubEddy guest it will be bundled with Broadcasting Provider companies).
Let's see that is HDTV:
- A TV set with a built-in digital tuner that can show high-definition broadcasts in true high-definition resolution.
- Also refers to the broadcasts themselves.
- According to CEA (US, not for HK), a fully integrated television set will receive all ATSC terrestrial digitaltransmissions and decode all ATSC Table 3 video formats.
- It must display activevertical scanning lines of 720 progressive (720p), 1080 interlaced (1080i), or higher
- in a 16:9 widescreen aspect ratio.
- It must also receive and decode or pass-through for decoding Dolby® Digital audio.
- It must also receive and decode or pass through ford ecoding 5.1 digital surround sound.
- According to the FCC, "HDTV is the best qualityTV".
