What is HDTV?

HDTV is a new for broadcasting TV programming. HDTV is an acronym for Television.  It is the high-end of digital cable, and provides the highest quality TV viewing experience available. It can be received via satellite or, where available, by converting a special HDTV signal transmitted over a digital cable connection. Digitally encoding a television picture is known as DTV, or Digital Television. A signal that is DTV is not necessarily HDTV – think of small dish systems and the digital channels on the 4DTV system. However, all HDTV signals are DTV – or digital. Bottom-line is HDTV provides 5 times better resolution than regular TV Analog signal.

Requirements to receive HDTV video?

HDTV Requirements

Buy a HDTV that have ATSC or DTV Tuner built-in in order to view the highly detailed video images of . ATSC / DTV is the tuner for receiving signal. NTSC Tuner is for regular TV. Usually a HDTV Ready does not have an Integrated DTV Tuner inside the TV. One need to buy the DTV tuner in order to receive channel. Or rent a Ready Cable box from the Cable company.

HD Signal source :  Next the TV Input Signal must be in HD format. To get  HD format, either use a HDTV Antenna, subscribe to a HD Cable from the Cable company. Cable company usually lease or provides a HD  Digital Cable Box.

Using an Air HDTV Antenna, you can also able to receive some TV channels, currently being broadcast in HD format.

I/O Cable : Currently non HD TV uses RCA or S-Video cable to receive TV signal. For HDTV, it uses HDMI, Component or DVI cable to transfer the highest best quality, uncompressed Video & Audio data to the HDTV.

Right Channel : The HD Channel and Standard usually are on different channel. So, refer to your Cable TV programming guide.

Other Sources : Besides Cable HD Channel, you can also able to use Satellite Dish, Up-Convert DVD , HD DVD , Blu Ray DVD , Media HD Movie to view High Definition /video. XBox 360 is also able to deliver HD to your HDTV too!

What is the differences between old Regular TV and HDTV?

Display quality : Standard NTSC TV display about 480 lines of resolution from top to bottom. HDTV display 1080 lines of resolution. It’s twice the number of lines vertically and horizontally compared to the NTSC TV. So, the HDTV displays a very fine detailed images.

Audio Quality : Audio Quality: The improvement in audio quality over traditional analog TV is greater than that of a CD versus a cassette tape. HDTV programming is capable of Dolby Digital 5.1 Surround Sound content, which mimics the three-dimensional sound heard in movie theaters.

Aspect Ratio :  defines the size of the display (Display width divided by the Display height). Traditional Analog TV display in 4:3 aspect Ratio. HDTV display in 16:9 Ratio in Widescreen format. This 16:9 Wide Screen is a more natural setting for our eyes and similar to those ratio used in Theatre released movie. Bottom-line is you get to see more on the HDTV screen. See below for Aspect Ratio comparison :

Hello friends! Today I’ll post a short list for portals.

Most popular video portals are : .com, .com, Video..com, Break.com,  Spike.com and others.

1 – Youtube.com

YouTube is a video sharing website on which users can and share videos. Three former PayPal employees created YouTube in February 2005. In November 2006, YouTube, LLC was bought by Google Inc. for $1.65 billion, and is now operated as a subsidiary of Google.

2 – Matecafe.com

Metacafe is a community based video sharing web site, that specializes in short-form original entertainment, where users upload, view and share video .

The company is headquartered in Palo Alto, California, with offices in Tel Aviv and New York. Metacafe is privately held and its investors include Accel Partners, Benchmark Capital, DAG Ventures and Highland Capital Partners.

3 – Break.com

Visitors were once able to rank site material on a scale of 1 to 5, but Break has since replaced this feature with a thumbs up/thumbs down system. Negative scores are not allowed on videos – a “thumb down” simply counteracts the vote of a “thumb up.” Users can also comment on most of the individual entries.google_video[1]

History of HD Movies

Hello friends! Today I’ll post a short list of History.

The developmental era (1948 – 1970s): low definition as

From a historical perspective, NTSC or System-M was the first television transmission .System-M held the high definition monopoly from 1948-1956. The only other existing TV broadcast systems in Europe at the time used either 405 lines (UK, also referred to as System-A) or 441 lines (France, but no system designator was ever issued).When the Europeans standardized on using 625 lines with either PAL and SECAM as the colour standard. Essentially PAL became the globally available high definition . The French tried an 819 line system that was Monochrome only, but abandoned it due to interoperability issues and lack of adoption in other countries other than Belgium.

1980s: Great technological leaps into dead ends

Original HD specifications date back to the early 1980s, when Japan developed the HighVision 1125-line TV standard (also called MUSE) that ran at 30 frames per second (frame/s or fps). Japan presented their standard at an international meeting of television engineers in Algiers in 1981 and Japan’s NHK presented its analog HDTV system at Swiss conference in 1983.The NHK system was standardized in the United States as SMPTE (Society of Motion Picture and Television Engineers) standard #240M in the early 1990s, but abandoned later on when it was replaced by a DVB analog standard. HighVision video is still usable for HDTV video interchange, but there is almost no equipment around to perform this function. All attempts at shoehorning in HighVision into a 6 MHz broadcast channel were mostly not successful. All attempts at using this format for terrestrial TV transmission were forsaken by the mid-1990s.The Europeans developed HD-MAC (1250 lines, 50 Hz) as a video standard, but it never took off as a terrestrial video transmission format. HD-MAC was never designated for video interchange except by the European Broadcasting Union.The current high definition video standards in North America were developed during the course of the advanced television process initiated by the Federal Communications Commission in 1987 at the request of American broadcasters. In essence the end of the 1980s was a death knell for most analog high definition technologies that had developed up to that time.

1990s: DVB and the brushfire of standardization

The FCC process, led by the Advanced Television Systems Committee (ATSC) adopted a range of standards from interlaced 1080 line video (a technical descendant of the original analog NHK 1125/30 frame/s system) with a maximum frame rate of 30 frame/s, and 720 line video, progressively scanned, with a maximum frame rate of 60 frame/s.In the end however the DVB standard of resolutions (1080, 720, 480…) and frame rates (24, 25, 30) were adopted in conjunction with the Europeans that were also involved in the same standardization process. The FCC officially adopted the ATSC transmission standard (which included both HD and SD video standards) in 1996, with the first broadcasts on October 28, 1998.

2000s: global HDTV adoption, but standardization deteriorates

In the early 2000s it looked as if DVD would be the video standard far into the future. However, both Brazil and China have adopted non-standard video codecs (mp4, and an open-source video codec) that somewhat violate the interoperability that was hoped for after decades of largely non-interoperable analog TV broadcasting. As high definition television has evolved into the mathematical representation of a video signal, and as computing power is so inexpensive these standardization issues so far have been minor.

Hello friends!

Today I’ll post a short list of popular media standards.

Here’s a short list of various video formats and standards.

8mm, Video8, Hi8, Digital8 – 8mm Video refers to a group of three video formats: Video8, Hi8 and Digital8. Together these formats, championed by Sony, played a very important part in the early history of consumer and pro-sumer camcorders.

1image1

 Beta, Betamax, Betacam, Betacam SP, Betacam SX , Digital Betacam - The Beta group of video formats includes the failed consumer-level Betamax as well as a number of very successful professional-level formats. The professional Beta formats have been leaders in the television production market, especially in the field of ENG (Electronic News Gathering).
1image2 DV, MiniDV, DVCAM, DVCPRO, DVCPRO50, DVCPRO , HDV – DV tapes can be played back in both DVCAM and DVCPRO VCRs.
1image3 DVD, Blu-Ray, HD-DVD, HD-VMD, CH-DVD – DVD comes in a variety of flavours which can be confusing. The different physical formats determine how data is stored (e.g. DVD-ROM); application formats determine how program content is stored and played (e.g. DVD-Video).

1image4 , MPEG-4 – VHS is a consumer-level video standard developed by JVC and launched in 1976. Originally VHS was an acronym for Vertical Helical Scan (a reference to the recording system used) but was later changed to the more consumer-friendly Video Home System.
