Tartışmalar > TRT taraflılık iddiası

İbrahim Şahin'in genel müdürlüğü sırasında, cumhurbaşkanlığı seçimleriyle ilgili yayınlarda taraflı davrandığı iddialarıyla ilgili olarak Selahattin Demirtaş tarafından suç duyurusunda bulunulmuştur. Bu iddialar RTÜK'te de ele alınmış, RTÜK üyesi Doç. Dr. Ahmet Yıldırım'ın çalışmasına göre 4-5-6 Temmuz tarihlerinde üç TRT kanalının adaylara ayırdığı zamanlar şöyledir: Recep Tayyip Erdoğan TRT Türk 305 dakika, TRT 1 24 dakika, TRT Haber 204 dakika; Ekmeleddin Mehmet İhsanoğlu TRT Türk 0 dakika, TRT 1 2 dakika 5 saniye, TRT Haber 1 dakika 20 saniye ve Selahattin Demirtaş TRT Türk 0 dk, TRT 1 0 dakika ve TRT Haber 45 saniye.
RTÜK Başkan Vekili Hasan Fendoğlu konuyla ilgili olarak 29 Haziran - 10 Temmuz döneminde TRT Haber yayımları için verileri şöyle açıklamıştır: Recep Tayyip Erdoğan 559 dakika, Ekmeleddin İhsanoğlu 137 dakika, Selahattin Demirtaş 18 dakika. Fendoğlu, Recep Tayyip Erdoğan'ın aynı zamanda başbakanlık sıfatının olduğunu, dolayısıyla kendisine ayrılan süreyle öteki adaylara ayrılan sürenin aynı olamayacağını belirtmiştir.
İbrahim Şahin konuyla ilgili 28 Temmuz 2014 bir açıklama yayımlamıştır. Bu açıklamada söz konusu iddiaların gerçeği yansıtmadığını ve Demirtaş'ın bu iddiaları TRT'nin canlı aktardığı bir etkinlikte tekrarlaması üzerine yayını keseceklerini söylemiştir.

Çerçeve oranı

Bir resmin çerçeve oranı eni ve boyu arasındaki oransal ilişkiyi tarif eder.
Çoğunlukla aralarında iki nokta bulunan iki numara şeklinde ifade edilir; örneğin, 16:9. Bir a:b çerçeve oranı için, görüntünün ne kadar büyük veya küçük olduğunun önemi yoktur
no matter how big or small the image is, if the width is divided into x units of equal length and the height is measured using this same length unit, the height will be measured to be y units. For example, consider a group of images, all with an aspect ratio of 16:9. One image is 16 inches wide and 9 inches high. Another image is 16 centimeters wide and 9 centimeters high. A third is 8 yards wide and 4.5 yards high.
Sinema salonlarındaki filmlerin sunuşunda, günümüzde kullanılan en yaygın çerçeve oranı 1.85:1 ve 2.39:1'dir.  Yaygın iki videografik çerçeve oranı; 20. yüzyılın evrensel video formatı olan 4:3 (1.33:1) ile yüksek çözünürlüklü televizyon ve Avrupa dijital televizyonu için evrensel olan 16:9'dur. (1.77:1). Seyrek olarak kullanılan diğer çerçeve oranları da mevcuttur.
In still camera photography, the most common aspect ratios are 4:3, 3:2, and more recently being found in consumer cameras 16:9. Other aspect ratios, such as 5:3, 5:4, and 1:1 (square format), are used in photography as well, particularly in medium format and large format.
With television, DVD and Blu-ray Disc, converting formats of unequal ratios is achieved by enlarging the original image to fill the receiving format's display area and cutting off any excess picture information (zooming and cropping), by adding horizontal mattes (letterboxing) or vertical mattes (pillarboxing) to retain the original format's aspect ratio, by stretching (hence distorting) the image to fill the receiving format's ratio, or by scaling by different factors in both directions, possibly scaling by a different factor in the center and at the edges (as in Wide Zoom mode).
Uygulamayla ilgili sınırlamalar

Sinema formatlarında, dişli performasyonların arasındaki film alanının fiziksel boyutu resmin boyutunu belirler. Evrensel standart, (1892'de William Dickson ve Thomas Edison tarafından kurulan) dört perforasyon yüksek olan bir çerçevedir. Filmin kendisi 35 mm genişliğindedir (1,38 inç), fakat perforasyonlar arasındaki alan 4:3 veya 1.33:1 "de facto" oranını bırakarak 24,89 mm×18,67 mm'dir (0,980 inç×0,735 inç). 4:3 oranı 4:3,075 olan (hemen hemen aynı) 155°h x 120°v insan gözü için görüş açısını taklit eder.
With a space designated for the standard optical soundtrack, and the frame size reduced to maintain an image that is wider than tall, this resulted in the Academy aperture of 22 mm × 16 mm (0.866 in × 0.630 in) or 1.37:1 aspect ratio.
Sinema terminolojisi

The motion picture industry convention assigns a value of 1.0 to the image's height; thus, an anamorphic frame (actually 2.39:1) is described (rounded) as 2.40:1 or 2.40 ("two-four-oh"). In American cinemas, the common projection ratios are 1.85:1 and 2.40:1. Some European countries have 1.66:1 as the wide screen standard. The "Academy ratio" of 1.37:1 was used for all cinema films until 1953 (with the release of George Stevens's Shane in 1.66:1). During that time, television, which had a similar aspect ratio of 1.33:1, became a threat to movie audiences, Hollywood gave birth to a large number of wide-screen formats: CinemaScope (up to 2.66:1), Todd-AO (2.20:1), and VistaVision (initially 1.50:1, now 1.66:1 to 2.00:1) to name just a few. The "flat" 1.85:1 aspect ratio was introduced in May, 1953, and became one of the most common cinema projection standards in the U.S. and elsewhere.
Sinema terminolojisi > Film kamerası sistemleri

Development of various film camera systems must ultimately cater to the placement of the frame in relation to the lateral constraints of the perforations and the optical soundtrack area. One clever wide screen alternative, VistaVision, used standard 35 mm film running sideways through the camera gate, so that the sprocket holes were above and below frame, allowing a larger horizontal negative size per frame as only the vertical size was now restricted by the perforations. However, the 1.50:1 ratio of the initial VistaVision image was optically converted to a vertical print (on standard 4-perforation 35 mm film) to show in the projectors available at theaters, and was then masked in the projector to the US standard of 1.85:1. The format was briefly revived by Lucasfilm in the 1970s for special effects work that required larger negative size (due to image degradation from the optical printing steps necessary to make multi-layer composites). It went into obsolescence largely due to better cameras, lenses, and film stocks available to standard 4-perforation formats, in addition to increased lab costs of making prints in comparison to more standard vertical processes. (The horizontal process was later adapted to 70 mm film by IMAX.)
Süper 16 mm film is frequently used for televizyon production due to its lower cost, lack of need for soundtrack space on the film itself (as it is not projected but rather transferred to video), and aspect ratio similar to 16:9 (the native ratio of Super 16 mm is 15:9). It also can be blown up to 35 mm for theatrical release and therefore is sometimes used for feature films.
Güncel video standartları > 4:3 standardı

Standart televizyon için 4:3 (1.33:1) (genellikle "dörde üç" olarak anılır)  has been in use since the invention of moving picture cameras and many computer monitors used to employ the same aspect ratio. 4:3 was the aspect ratio used for 35 mm films in the silent era. It is also very close to the 1.375:1 aspect ratio defined by the Sinema Sanatları ve Bilimleri Akademisi as a standard after the advent of optical sound-on-film. By having TV match this aspect ratio, movies originally photographed on 35 mm film could be satisfactorily viewed on TV in the early days of the medium (i.e. the 1940s and the 1950s). When sinema attendance dropped, film endüstrisini televizyondan farklılaştırmak amacıyla Hollywood geniş ekran çerçeve oranlarını (daha önce bahsedilen 1.85:1 oranı gibi) oluşturdu. Fakat However since the start of the 21st century broadcasters worldwide are phasing out the 4:3 standard entirely, as technology started to favour the 16:9/16:10 aspect ratio of all modern HD TV sets, computer monitors as well as broadcast cameras.
Güncel video standartları > 16:9 standardı

Ana madde: 16:9
16:9 (1.77:1) (genellikle on altıya dokuz olarak adlandırılır) HDTV, standart dijital televizyon ve PALplus analog geniş ekran televizyonun uluslararası standart formatıdır. Japonya'nın Hi-Vision'ı aslında 5:3 oranla başladı, fakat uluslararası standartlar grubu daha geniş bir 5⅓'e 3 oranını (=16:9) tanıtınca dönüştürüldü. Çok sayıda dijital video kamerası 16:9'da kayıt edebilme yeteneğine sahip ve 16:9 yalnızca geniş ekran çerçeve oranı doğallıkla is the only widescreen aspect ratio natively supported by DVD standardı tarafından doğallıkla  desteklenen. DVD producers can also choose to show even wider ratios such as 1.85:1 and 2.39:1 within the 16:9 DVD frame by hard matting or adding black bars within the image itself. Some films which were made in a 1.85:1 aspect ratio, such as the U.S.-Italian co-production Man of La Mancha, fit quite comfortably onto a 1.77:1 HDTV screen and have been issued anamorphically enhanced on DVD without the black bars.
Ekran yüksekliği, genişliği ve alanının hesaplanması

Çoğu zaman, ekran özellikleri diyagonal uzunluklarına göre verilir. Yükseklik (h), genişlik (uzunluk için l) ve alanı (A) bulmak için aşağıdaki formüller kullanılabilir; burada r oran ve d köşegen uzunluk anlamına gelir.
h={\frac {d}{\sqrt {(r^{2}+1)}}}\qquad l={\frac {d}{\sqrt {{\frac {1}{r^{2}}}+1}}}\qquad A={\frac {d^{2}}{r+{\frac {1}{r}}}}

Bu makale öncelikle, daha resmi olarak görüntü en boy oranı (DAR) olarak adlandırılan, görüntülenen görüntülerin en boy oranını ele almaktadır. Dijital görüntülerde, piksel boyutlarının oranı olan depolama en boy oranı (SAR) ile bir ayrım vardır. Bir görüntü kare piksellerle görüntüleniyorsa, bu oranlar aynı olur; değilse, o zaman kare olmayan "dikdörtgen" pikseller kullanılır ve bu oranlar uyuşmaz. Piksellerin en boy oranı, piksel en boy oranı (PAR) olarak bilinir - kare pikseller için bu 1:1'dir - ve bunlar özdeşlikle ilişkilidir:
Rearranging (solving for PAR) yields:
For example, a 640 × 480 VGA image has a SAR of 640/480 = 4:3, and if displayed on a 4:3 display (DAR = 4:3), has square pixels, hence a PAR of 1:1. By contrast, a 720 × 576 D-1 PAL image has a SAR of 720/576 = 5:4, but is displayed on a 4:3 display (DAR = 4:3), so by this formula it would have a PAR of (4:3)/(5:4) = 16:15.
However, because standard definition digital video was originally based on digitally sampling analog television, the 720 horizontal pixels actually capture a slightly wider image to avoid loss of the original analog picture. In actual images, these extra pixels are often partly or entirely black, as only the center 704 horizontal pixels carry actual 4:3 or 16:9 image. Hence, the actual pixel aspect ratio for PAL video is a little different from that given by the formula, specifically 12:11 for PAL and 10:11 for NTSC. For consistency, the same effective pixel aspect ratios are used even for standard definition digital video originated in digital form rather than converted from analog. For more details refer to the main article.
In analog images such as film there is no notion of pixel, nor notion of SAR or PAR, and "aspect ratio" refers unambiguously to DAR. Actual displays do not generally have non-square pixels, though digital sensors might; they are rather a mathematical abstraction used in resampling images to convert between resolutions.
Non-square pixels arise often in early digital TV standards, related to digitalization of analog TV signals – whose horizontal and vertical resolutions differ and are thus best described by non-square pixels – and also in some digital videocameras and computer display modes, such as Color Graphics Adapter (CGA). Today they arise particularly in transcoding between resolutions with different SARs.
DAR is also known as image aspect ratio and picture aspect ratio, though the latter can be confused with pixel aspect ratio.

Comparing two different aspect ratios poses some subtleties – when comparing two aspect ratios, one may compare images with equal height, equal width, equal diagonal, or equal area. More amorphous questions include whether particular subject matter has a natural aspect ratio (panoramas being wide, full-length images of people being tall), or whether a particular ratio is more or less aesthetically pleasing – the golden ratio (~1.618) is seen as especially pleasing. Of common display formats, 16:10 (8/5) is the closest to the golden ratio, and 15:9 is the closest film format.
Given the same diagonal, the 4:3 screen offers more (over 12%) area, because it is closer to square (which maximizes area given a diagonal). For CRT-based technology, an aspect ratio that is closer to square is cheaper to manufacture. The same is true for projectors, and other optical devices such as cameras, camcorders, etc. For LCD and Plasma displays, however, the cost is more related to the area, so producing wider and shorter screens yields the same advertised diagonal but lower area, and hence is more profitable.
The following compares crops of a given image at 4:3 and 16:9, with different parameters equal; note that in terms of subject, the squarer aspect ratio emphasizes the public square, while the wider aspect ratio emphasizes the wide building.
Two aspect ratios compared with images using the same diagonal size:

Original Aspect Ratio (OAR) is a home cinema term for the aspect ratio or dimensions in which a film or visual production was produced – as envisioned by the people involved in the creation of the work. As an example, the film Gladiator was released to theaters in the 2.39:1 aspect ratio. It was filmed in Super 35 and, in addition to being presented in cinemas and television in the Original Aspect Ratio of 2.39:1, it was also broadcast without the matte altering the aspect ratio to the television standard of 1.33:1. Because of the varied ways in which films are shot, IAR (Intended Aspect Ratio) is a more appropriate term, but is rarely used.

Modified Aspect Ratio is a home cinema term for the aspect ratio or dimensions in which a film was modified to fit a specific type of screen, as opposed to original aspect ratio. Modified aspect ratios are usually either 1.33:1 (historically), or (with the advent of widescreen television sets) 1.77:1 aspect ratio. 1.33:1 is the modified aspect ratio used historically in VHS format. A modified aspect ratio transfer is achieved by means of pan and scan or open matte, the latter meaning removing the cinematic matte from a 1.85:1 film to open up the full 1.33:1 frame. Another name for it is "prescaled" aspect ratio".

Multiple aspect ratios create additional burdens on filmmakers and consumers, and confusion among TV broadcasters. It is common for a widescreen film to be presented in an altered format (cropped, letterboxed or expanded beyond the original aspect ratio). It is also not uncommon for windowboxing to occur (when letterbox and pillarbox happen simultaneously). For instance, a 16:9 broadcast could embed a 4:3 commercial within the 16:9 image area. A viewer watching on a standard 4:3 (non-widescreen) television would see a 4:3 image of the commercial with 2 sets of black stripes, vertical and horizontal (windowboxing or the postage stamp effect). A similar scenario may also occur for a widescreen set owner when viewing 16:9 material embedded in a 4:3 frame, and then watching that in 16:9. Active Format Description is a mechanism used in digital broadcasting to avoid this problem. It is also common that a 4:3 image is stretched horizontally to fit a 16:9 screen to avoid pillar boxing but distorts the image so subjects appear short and fat.
Both PAL and NTSC have provision for some data pulses contained within the video signal used to signal the aspect ratio (See ITU-R BT.1119-1 – Widescreen signaling for broadcasting). These pulses are detected by television sets that have widescreen displays and cause the television to automatically switch to 16:9 display mode. When 4:3 material is included (such as the aforementioned commercial), the television switches to a 4:3 display mode to correctly display the material. Where a video signal is transmitted via a European SCART connection, one of the status lines is used to signal 16:9 material as well.

Common aspect ratios in still photography include:
1:1
4:3 (1.33:1)
3:2 (1.5:1)
5:3 (1.66:1)
16:9 (1.77:1)
3:1
Many digital still cameras offer user options for selecting multiple image aspect ratios. Some achieve this through the use of multi-aspect sensors (notably Panasonic), while others simply crop their native image format to have the output match the desired image aspect ratio.

is the classic square image, and is available as a choice in some digital still cameras, and harkens back to the days of film cameras when the square image was somewhat popular with photographers using medium format cameras shooting 120 film rolled onto spools. The 6 × 6 cm image size was the classic 1:1 format in the recent past. 120 film can still be found and used today.

is used by most digital point-and-shoot cameras, Four Thirds system, Micro Four Thirds system cameras and medium format 645 cameras. The 4:3 digital format popularity was developed to match the then prevailing digital displays of the time, 4:3 computer monitors.
The next several formats have their roots in classic film photography image sizes, both the classic 35 mm film camera, and the multiple format Advanced Photo System (APS) film camera. The APS camera was capable of selecting any of three image formats, APS-H ("High Definition" mode), APS-C ("Classic" mode) and APS-P ("Panoramic" mode).
Daha fazla bilgi: Piksel en boy oranı > Still photography > 3:2

is used by classic 35 mm film cameras using a 24 mm × 36 mm image size, and their digital derivatives represented by DSLRs. Typical DSLRs come in two flavors, the so-called professional "full frame" (24 mm × 36 mm) sensors and variations of smaller, so called "APS-C" sensors. The term "APS" is derived from another film format known as  
the APS and the "-C" refers to "Classic" mode, which exposed images over a smaller area (25.1 mm × 16.7 mm) but retaining the same "classic" 3:2 proportions as full frame 35 mm film cameras.
When discussing DSLR's and their non-SLR derivatives, the term APS-C has become an almost generic term. The two major camera manufacturers Canon and Nikon each developed and established sensor standards for their own versions of APS-C sized and proportioned sensors. Canon actually developed two standards, APS-C and a slightly larger area APS-H (not to be confused with the APS-H film format), while Nikon developed its own APS-C standard, which it calls DX. Regardless of the different flavors of sensors, and their varying sizes, they are close enough to the original APS-C image size, and maintain the classic 3:2 image proportions that these sensors are generally known as an "APS-C" sized sensor.
The reason for DSLR image sensors being the flatter 3:2 versus the taller point-and-shoot 4:3 is that DSLRs were designed to match the legacy 35 mm SLR film, whereas the majority of digital cameras were designed to match the predominant computer displays of the time, with VGA, SVGA, XGA and UXGA all being 4:3. Widescreen computer monitors did not become popular until the advent of HDTV which uses a 16:9 image aspect ratio.

16:9 is another format that has its roots in the APS film camera. Known as APS-H (30.2 mm × 16.7 mm), with the "-H" denoting "High Definition", the 16:9 format is also the standard image aspect ratio for HDTV. 16:9 is gaining popularity as a format in all classes of consumer still cameras which also shoot High Definition (HD) video. When still cameras  have an HD video capability, some can also record stills in the 16:9 format, ideal for display on HD televisions and widescreen computer displays.
