3D Technology Checklist
This product is hdtv TC-P55GT30-related. To help you get a great 3D hdtv TC-P55GT30 experience,
use the checklist
use the checklist
below to ensure you have everything you need. 3D viewing requires:
 | A Display First, you'll need a 3D-ready display--whether it's a 3D hdtv TC-P55GT30, 3D projector, or 3D computer monitor. These displays have more processing power than standard 2D models for displaying 3D images in rapid succession. |
 | A Source Your display may be ready for 3D playback, but you'll still need a device to read 3D content. This can be a cable box with a subscription to a 3D channel, a 3D Blu-ray Disc player, or a PlayStation 3 system. |
 | 3D Content 3D content--the actual entertainment, in other words--will be played back using the source mentioned above, whether it's a 3D broadcast from your cable provider, a 3D Blu-ray Disc, or a 3D video game. |
 | 3D Glasses For now, the vast majority of 3D hdtv TC-P55GT30 require glasses for 3D viewing. Many use powered "active shutter" glasses, others polarized "passive" glasses. You'll need one pair per viewer, and they'll have to be compatible with your display, whether they're the same brand, or a pair of "universal" glasses designed to work across brands. |
 | HDMI Cable To connect your source (such as a 3D Blu-ray Disc player) to your display, you'll need a high-speed HDMI cable. Cables with this designation feature bandwidth speeds up to 10.2 Gbps (gigabits per second), for carrying the 3D signal without any loss of quality. |

Internet-Ready Television
Step into the 3D World. The VIERA GT30 Series Full HD 3D Plasmas hdtv TC-P55GT30 create an all new viewing experience by putting you inside the action and creating a new world of TV viewing realism.
Infinite Black 2
In new VIERA hdtv TC-P55GT30 models, contrast in brightly lit locations has been significantly improved. Enhancements to the panel and cells help reproduce images with smooth, natural gradation and deep, rich blacks even when viewed in bright surroundings. In movies, the true, deep blacks faithfully convey the intent of the filmmakers, adding power and realism to the viewing experience.
Full-time 1080 Moving Picture Resolution
VIERA hdtv TC-P55GT30 plasma TVs have 1,080 lines of moving-picture resolution. Newly developed phosphors with minimal afterimages and a new motion compensating technology have made it possible to render faster-moving images with greater sharpness. This far surpasses the APDC moving-picture resolution measurement standard of 5 seconds by providing a moving-picture resolution of 1,080 lines at the 1.5-second level. And it shows the inherently clear motion of VIERA TVs hdtv TC-P55GT30 in both 2D and 3D images.
3D 24p Cinema Smoother
VIERA hdtv TC-P55GT30 incorporates technology that analyzes picture information in both the preceding and succeeding frames, and creates a precise supplementary frame between them. This suppresses the jerky effect seen in movies, so playback is smooth and natural-looking. The distinctive tonal qualities and atmosphere of the movie are preserved, and you enjoy extremely lifelike 3D images.
Frame Sequential Technology
Panasonic uses Full-HD Frame Sequential technology to create its 3D images. Images recorded in 1920 x 1080 pixels for both the right-eye and the left-eye alternately flash on the screen at the ultra-high rate of 120 frames per second. When you view the screen through active-shutter glasses that open and close each lens in sync with the alternating images, you see breathtaking FULL HD 3D pictures with stunning power and realism.
Dynamic Contast
By combining the highly light-transmissive IPS Alpha Panel and high-brightness backlight, Panasonic have attained both high contrast and low power consumption. Also, by detecting the contrasting parts of the scene, the backlight is adjusted to maintain a brightness that is optimal for each area. Deep blacks are reproduced with no fading. The contrast between the brilliance of diamond-like stars and the deep black of the night sky produces a sharp, crisp image.600Hz Sub-field Drive
600Hz technology lets you view superb full-HD motion and still images. For even greater clarity with motion images, Panasonic uses its own unique image-analysis technology. This technology converts the motion in each scene into dots. And each frame is practically displayed for a shorter length of time than in previous systems, to reduce aftereffects.
Game Mode
Games are much more fun when there's no lag in operation. VIERA hdtv TC-P55GT30 automatically chooses settings that provide the optimal image, so you get super-fast response and no delays. Even dark scenes with delicately rendered details are beautiful and easy to see.
3D Image Viewer
After shooting with your 3D-compatible camera or camcorder, simply insert the SD card
into the slot on a 3D-compatible VIERA hdtv TC-P55GT30 TV. The viewing is incredible, with images so
realistic it feels as though you're right back in the moment. You'll find that life's special
moments are even more memorable when you preserve them in 3D.
The exciting world of IPTV, centering on TV, is about to begin for the enjoyment of the entire family.

Customer Reviews
This review is from: Panasonic VIERA TC-P55GT30 55-Inch 1080p 3D Plasma HDTV (Electronics) |
This review is only for the 2D picture quality only. I do not have the 3D glasses and I am not sure I will get them, 3d doesn't interest me that much. I primarily bought it because it was plasma and not LCD. I have had CRT projection, DLP projection and LCD. The LCD was a Samsung and a great TV but I did not like the soap opera visual effect it had on some content. The picture was clear but looked artificial. I believe I have read some other reviews on Amazon stating the same observations. I purchased this TV based on online research and the positive reviews by professional review sites and user feedback. The off angle viewing, no lag or artifacts when viewing fast action content were the two most important aspects to me, researching all the different display types will find, plasma is the king of the hill on both counts. I would not hesitate to recommend this TV to anyone. If you do the research you will find it is the top of the game and amazon had a really good price coupled with the 2 year interest free amazon sore card purchase it was a no brainer. The form factor although not as slim as the slimmest LCD's is still under 2 inches and looks great hanging on the wall. Panasonic 55 inch GT30, Amazon Verified Purchase(What's this?) This review is from: Panasonic VIERA TC-P55GT30 55-Inch 1080p 3D Plasma HDTV (Electronics) As many others, I've done my research before buying this TV. I've only had the GT30 for 4days and am currently very happy with it. - The 2D picture is beautiful. I have another 2 year old Samsung 1080P LCD and I can see a clear picture improvement with this Panasonic GT30. I was a little worried about the fluctuating brightness problems that people have been seeing. I am happy to report that I do not see ANY fluctuating brightness issues in any of the modes (thx, game, custom, etc...) Out of the box the THX mode seemed to be the best, but I found some tunings that CNET posted for this TV and used those. CNET actually posted picture tunings for THX and Custom modes and mentioned that they believe their THX settings were better. My wife and I prefer like their Custom settings more than their THX settings. More realistic... - I can also make a couple of comments on 3D. I've ordered a 3D blue ray player with a few movies, but have not received them yet. I do have ESPN 3D though and was able to check it out. I purchased the x103 3d glasses and used those. The 3d effect greatly depends on the content that you are watching on TV when its broadcast. College football was OK, Extreme winter games were good and Boxing looked great with 3D. I did not see any cross talk and the HD clarity was very good. Just make sure that you don't have a lot of extra outside light in the room or the glasses will appear to flicker a little. In a medium to dim environment, there were 0 issues. I can't wait for the 3D blue ray player to see what movies will look like on this TV. Overall I am very happy with this TV. |

WIKIPEDIA and HDTV
History of high-definition television
Further information: Analog high-definition television system and History of television
On 2 November 1936 the BBC began transmitting the world's first public regular high-definition service from the Victorian Alexandra Palace in north London.[1] It therefore claims to be the birthplace of television broadcasting as we know it today.
The term high definition once described a series of television systems originating from the late 1930s; however, these systems were only high definition when compared to earlier systems that were based on mechanical systems as few as 30 lines of resolution.
The British high definition TV service started trials in August 1936 and a regular service in November 1936 using both the (mechanical) Baird 240 line and (electronic) Marconi-EMI 405 line (377i) systems. The Baird system was discontinued in February 1937. In 1938 France followed with their own 441 line system, variants of which were also used by a number of other countries. The US NTSC system joined in 1941. In 1949 France introduced an even higher resolution standard at 819 lines (768i), a system that would be high definition even by today's standards, but it was monochrome only. All of these systems used interlacing and a 4:3 aspect ratio except the 240 line system which was progressive (actually described at the time by the technically correct term "sequential") and the 405 line system which started as 5:4 and later changed to 4:3. The 405 line system adopted the (at that time) revolutionary idea of interlaced scanning to overcome the flicker problem of the 240 line with its 25 Hz frame rate. The 240 line system could have doubled its frame rate but this would have meant that the transmitted signal would have doubled in bandwidth, an unacceptable option.
Color broadcasts started at similarly higher resolutions, first with the US NTSC color system in 1953, which was compatible with the earlier B&W systems and therefore had the same 525 lines (480i) of resolution. European standards did not follow until the 1960s, when the PAL and SECAM colour systems were added to the monochrome 625 line (576i) broadcasts.
Since the formal adoption of Digital Video Broadcasting's (DVB) widescreen HDTV transmission modes in the early 2000s the 525-line NTSC (and PAL-M) systems as well as the European 625-line PAL and SECAM systems are now regarded as standard definition television systems. In Australia, the 625-line digital progressive system (with 576 active lines) is officially recognized as high definition.[2]
[edit]Analog systems
Main article: analog high-definition television system
In 1949, France started its transmissions with an 819 lines system (768i). It was monochrome only, it was used only on VHF for the first French TV channel, and it was discontinued in 1985.
In 1958, the Soviet Union developed Тransformator (Russian: Трансформатор, Transformer), the first high-resolution (definition) television system capable of producing an image composed of 1,125 lines of resolution aimed at providing teleconferencing for military command. It was a research project and the system was never deployed in the military or broadcasting.[3]
In 1979, the Japanese state broadcaster NHK first developed consumer high-definition television with a 5:3 display aspect ratio.[4] The system, known as Hi-Vision or MUSE after itsMultiple sub-Nyquist sampling encoding for encoding the signal, required about twice the bandwidth of the existing NTSC system but provided about four times the resolution (1080i/1125 lines). Satellite test broadcasts started in 1989, with regular testing starting in 1991 and regular broadcasting of BS-9ch commenced on 25 November 1994, which featured commercial and NHK programming.
In 1981, the MUSE system was demonstrated for the first time in the United States, using the same 5:3 aspect ratio as the Japanese system.[5] Upon visiting a demonstration of MUSE in Washington, US President Ronald Reagan was most impressed and officially declared it "a matter of national interest" to introduce HDTV to the USA.[6]
Several systems were proposed as the new standard for the USA, including the Japanese MUSE system, but all were rejected by the FCC because of their higher bandwidth requirements. At this time, the number of television channels was growing rapidly and bandwidth was already a problem. A new standard had to be more efficient, needing less bandwidth for HDTV than the existing NTSC.
[edit]Demise of analog HD systems
The limited standardization of analogue HDTV in the 1990s did not lead to global HDTV adoption as technical and economic reasons at the time did not permit HDTV to use bandwidths greater than normal television.
Early HDTV commercial experiments such as NHK's MUSE required over four times the bandwidth of a standard-definition broadcast—and HD-MAC was not much better. Despite efforts made to reduce analog HDTV to about 2x the bandwidth of SDTV these television formats were still only distributable by satellite.
In addition, recording and reproducing an HDTV signal was a significant technical challenge in the early years of HDTV (Sony HDVS). Japan remained the only country with successfulpublic broadcasting analog HDTV, with seven broadcasters sharing a single channel. Digital HDTV broadcasting started in 2000 in Japan, and the analog service ended in the early hours of 1 October 2007.
[edit]Rise of digital compression
Since 1972, International Telecommunication Union's radio telecommunications sector (ITU-R) has been working on creating a global recommendation for Analogue HDTV. These recommendations however did not fit in the broadcasting bands which could reach home users. The standardization of MPEG-1 in 1993 also led to the acceptance of recommendationsITU-R BT.709.[7] In anticipation of these standards the Digital Video Broadcasting (DVB) organisation was formed, an alliance of broadcasters, consumer electronics manufacturers and regulatory bodies. The DVB develops and agrees on specifications which are formally standardised by ETSI.[8]
DVB created first the standard for DVB-S digital satellite TV, DVB-C digital cable TV and DVB-T digital terrestrial TV. These broadcasting systems can be used for both SDTV and HDTV. In the USA the Grand Alliance proposed ATSC as the new standard for SDTV and HDTV. Both ATSC and DVB were based on the MPEG-2 standard. The DVB-S2 standard is based on the newer and more efficient H.264/MPEG-4 AVC compression standards. Common for all DVB standards is the use of highly efficient modulation techniques for further reducing bandwidth, and foremost for reducing receiver-hardware and antenna requirements.
In 1983, the International Telecommunication Union's radio telecommunications sector (ITU-R) set up a working party (IWP11/6) with the aim of setting a single international HDTV standard. One of the thornier issues concerned a suitable frame/field refresh rate, the world already having split into two camps, 25/50 Hz and 30/60 Hz, related by reasons of picture stability to the frequency of their main electrical supplies.
The IWP11/6 working party considered many views and through the 1980s served to encourage development in a number of video digital processing areas, not least conversion between the two main frame/field rates using motion vectors, which led to further developments in other areas. While a comprehensive HDTV standard was not in the end established, agreement on the aspect ratio was achieved.
Initially the existing 5:3 aspect ratio had been the main candidate but, due to the influence of widescreen cinema, the aspect ratio 16:9 (1.78) eventually emerged as being a reasonable compromise between 5:3 (1.67) and the common 1.85 widescreen cinema format. (Bob Morris explained that the 16:9 ratio was chosen as being the geometric mean of 4:3, Academy ratio, and 2.4:1, the widest cinema format in common use, in order to minimize wasted screen space when displaying content with a variety of aspect ratios.[9])
An aspect ratio of 16:9 was duly agreed at the first meeting of the IWP11/6 working party at the BBC's Research and Development establishment in Kingswood Warren. The resulting ITU-R Recommendation ITU-R BT.709-2 ("Rec. 709") includes the 16:9 aspect ratio, a specified colorimetry, and the scan modes 1080i (1,080 actively interlaced lines of resolution) and1080p (1,080 progressively scanned lines). The British Freeview HD trials used MBAFF, which contains both progressive and interlaced content in the same encoding.
It also includes the alternative 1440×1152 HDMAC scan format. (According to some reports, a mooted 750-line (720p) format (720 progressively scanned lines) was viewed by some at the ITU as an enhanced television format rather than a true HDTV format,[10] and so was not included, although 1920×1080i and 1280×720p systems for a range of frame and field rates were defined by several US SMPTE standards.)
[edit]Inaugural HDTV broadcast in the United States
HDTV technology was introduced in the United States in the 1990s by the Digital HDTV Grand Alliance, a group of television, electronic equipment, communications companies and the Massachusetts Institute of Technology.[11][12] Field testing of HDTV at 199 sites in the United States was completed August 14, 1994.[13] The first public HDTV broadcast in the United States occurred on July 23, 1996 when the Raleigh, North Carolina television station WRAL-HD began broadcasting from the existing tower of WRAL-TV south-east of Raleigh, winning a race to be first with the HD Model Station in Washington, D.C., which began broadcasting July 31, 1996 with the callsign WHD-TV, based out of the facilities of NBC owned and operated station WRC-TV.[14][15][16] The American Advanced Television Systems Committee (ATSC) HDTV system had its public launch on October 29, 1998, during the live coverage of astronautJohn Glenn's return mission to space on board the Space Shuttle Discovery.[17] The signal was transmitted coast-to-coast, and was seen by the public in science centers, and other public theaters specially equipped to receive and display the broadcast.[17][18]
[edit]European HDTV broadcasts
Although HDTV broadcasts had been demonstrated in Europe since the early 1990s, the first regular broadcasts started on January 1, 2004 when the Belgian company Euro1080launched the HD1 channel with the traditional Vienna New Year's Concert. Test transmissions had been active since the IBC exhibition in September 2003, but the New Year's Day broadcast marked the official start of the HD1 channel, and the start of HDTV in Europe.[19]
Euro1080, a division of the Belgian TV services company Alfacam, broadcast HDTV channels to break the pan-European stalemate of "no HD broadcasts mean no HD TVs bought means no HD broadcasts..." and kick-start HDTV interest in Europe.[20] The HD1 channel was initially free-to-air and mainly comprised sporting, dramatic, musical and other cultural events broadcast with a multi-lingual soundtrack on a rolling schedule of 4 or 5 hours per day.
These first European HDTV broadcasts used the 1080i format with MPEG-2 compression on a DVB-S signal from SES Astra's 1H satellite. Euro1080 transmissions later changed to MPEG-4/AVC compression on a DVB-S2 signal in line with subsequent broadcast channels in Europe.
The number of European HD channels and viewers has risen steadily since the first HDTV broadcasts, with SES Astra's annual Satellite Monitor market survey for 2010 reporting more than 200 commercial channels broadcasting in HD from Astra satellites, 185 million HD-Ready TVs sold in Europe (£60 million in 2010 alone), and 20 million households (27% of all European digital satellite TV homes) watching HD satellite broadcasts (16 million via Astra satellites).[21]
In December 2009 the United Kingdom became the first European country to deploy high definition content on digital terrestrial television (branded as Freeview) using the new DVB-T2transmission standard as specified in the Digital TV Group (DTG) D-book. The Freeview HD service currently contains 4 HD channels and is now rolling out region by region across the UK in accordance with the digital switchover process. Some transmitters such as the Crystal Palace and Emley Moor transmitters are broadcasting the Freeview HD service ahead of the digital switchover by means of a temporary, low-power pre-DSO multiplex.
[edit]Notation
HDTV broadcast systems are identified with three major parameters:
- Frame size in pixels is defined as number of horizontal pixels × number of vertical pixels, for example 1280 × 720 or 1920 × 1080. Often the number of horizontal pixels is implied from context and is omitted, as in the case of 720p and 1080p.
- Scanning system is identified with the letter p for progressive scanning or i for interlaced scanning.
- Frame rate is identified as number of video frames per second. For interlaced systems an alternative form of specifying number of fields per second is often used.[citation needed]
If all three parameters are used, they are specified in the following form: [frame size][scanning system][frame or field rate] or [frame size]/[frame or field rate][scanning system].[citation needed] Often, frame size or frame rate can be dropped if its value is implied from context. In this case the remaining numeric parameter is specified first, followed by the scanning system.
For example, 1920×1080p25 identifies progressive scanning format with 25 frames per second, each frame being 1,920 pixels wide and 1,080 pixels high. The 1080i25 or 1080i50 notation identifies interlaced scanning format with 25 frames (50 fields) per second, each frame being 1,920 pixels wide and 1,080 pixels high.[citation needed] The 1080i30 or 1080i60 notation identifies interlaced scanning format with 30 frames (60 fields) per second, each frame being 1,920 pixels wide and 1,080 pixels high.[citation needed] The 720p60 notation identifies progressive scanning format with 60 frames per second, each frame being 720 pixels high; 1,280 pixels horizontally are implied.
50 Hz systems support three scanning rates: 25i, 25p and 50p. 60 Hz systems support a much wider set of frame rates: 23.976p, 24p, 29.97i/59.94i, 29.97p, 30p, 59.94p and 60p. In the days of standard definition television, the fractional rates were often rounded up to whole numbers, e.g. 23.976p was often called 24p, or 59.94i was often called 60i. 60 Hz high definition television supports both fractional and slightly different integer rates, therefore strict usage of notation is required to avoid ambiguity. Nevertheless, 29.97i/59.94i is almost universally called 60i, likewise 23.976p is called 24p.[citation needed]
For commercial naming of a product, the frame rate is often dropped and is implied from context (e.g., a 1080i television set). A frame rate can also be specified without a resolution. For example, 24p means 24 progressive scan frames per second, and 50i means 25 interlaced frames per second.[22]
There is no standard for HDTV color support. Until recently the color of each pixel was regulated by three 8-bit color values, each representing the level of red, blue, and green which defined a pixel color. Together the 24 total bits defining color yielded just under 17 million possible pixel colors. Recently[when?] some manufacturers have produced systems that can employ 10 bits for each color (30 bits total) which provides for a palette of 1 billion colors, saying that this provides a much richer picture, but there is no agreed way to specify that a piece of equipment supports this feature. Human vision can only discern approximately 1 million colors so an expanded color palette is of questionable benefit to consumers.
Most HDTV systems support resolutions and frame rates defined either in the ATSC table 3, or in EBU specification. The most common are noted below.
