This chart shows the most common display resolutions, 720p shown in blue.

720p refers to a progressive HDTV signal with 720 horizontal lines and an aspect ratio (AR) of 16:9 (1.78:1). All major high definition (HD) TV broadcasting standards include a 720p format which has a resolution of 1280×720, however there are other formats, including HDV and AVCHD for camcorders, which utilize 720p images with the standard HDTV resolution. The number 720 stands for the 720 horizontal scan lines of image display resolution (also known as 720 pixels of vertical resolution), while the letter p stands for progressive scan (i.e. non-interlaced).^[1] When broadcast at 60^{[note 1]} frames per second, 720p features the highest temporal (motion) resolution possible under the ATSC and DVB standards.

720i (720 lines interlaced) is an erroneous term found in numerous sources and publications. Typically, it is a typographical error in which the author is referring to the 720p HDTV format. However, in some cases it is incorrectly presented as an actual alternative format to 720p.^[3] In fact, no proposed or existing broadcast standard permits 720 interlaced lines in a video frame at any frame rate.^[4] 720i can also refer to technology in which only half the lines are shown each scan.

Comparison with 1080i[link]

Progressive scanning reduces the need to prevent twitter (flicker) by anti-aliasing single high contrast horizontal lines.^[5][6] It is also easier to perform high-quality 50↔60 Hz conversion and slow-motion clips with progressive video. In high-motion scenes, 720p has higher vertical resolution than 1080i (720 versus 540 lines/progressive frame), making it preferable for fast-moving sporting events (such as auto racing or basketball) and for video games.

One main advantage for 720p60 over 480i and 1080i60 (29.97/30 frame/s, 59.94/60 Hz) is the reduction of 3:2 artifacts introduced during transfer from 24 frame/s film. However, 576i and 1080i50 (25 frame/s, 50 Hz), which are common in Europe, generally do not suffer from pull down artifacts as film frames are simply played at 25 frames and the audio pitch corrected by 24/25ths. As a result, 720p60 is used for US broadcasts while European HD broadcasts often use 1080i50 (25 frame/s, 50 Hz), with a horizontal resolution of 1920 or 1440 depending on bandwidth constraints. However, some European broadcasters do use the 720p50 format, such as German broadcasters ARD and ZDF, the Flemish Broadcasting Company (VRT) in Belgium and the Norwegian Broadcasting Corporation (NRK). Arte, a dual-language French-German channel produced in collaboration by ARD, ZDF and France Télévisions, broadcasts in German at 720p50 but in French at 1080i50.

Notes[link]

References[link]

The Classic (Hangul: 클래식; Keulraesik) is a 2003 South Korean melodrama / romance film directed by Kwak Jae-yong.

Plot[link]

The film tells the parallel love stories of a mother and daughter. The story of the mother is told partially in flashbacks.

The movie starts in the present day. The daughter, Ji-hye (Son Ye-jin), is cleaning-up around her house when she comes across a box full of old letters and a diary that detail the story of her mother, Joo-hee (who is also played by Son Ye-jin). Periodically in the movie, Ji-hye reads one of these letters, which starts a flashback scene in which the story of the mother is told. These flashbacks are intertwined with Ji-hye's own story, in which she falls for a fellow student, Sang-min (Zo In Sung), who is involved with the school theater.

The movie tells the story of both relationships. The mother, Joo-hee, visits the countryside as a student one summer and meets Joon-ha (Jo Seung-woo). Together they explore the countryside, playing near a river which they both will always remember as their special place. When a storm starts they take shelter together under a tree, but not before Joo-hee twists her ankle and is rendered helpless. Joon-ha carries her on his back and they struggle home, only to be confronted by her angry parents. Before they separate, Joo-hee gives him a necklace, which he keeps close as a precious reminder of their time together.

Unfortunately, as often happens in affairs of the heart, a third party prevents any deepening of their relationship. Joo-hee has been promised by her parents as a bride to Tae-soo, Joon-ha's friend. But Tae-soo, a noble friend, finds out about Joo-hee and Joon-ha's attraction for each other and helps the two communicate secretly by letting them use his own name in place of Joon-ha's in their letters. When Tae-soo's father finds this out, however, he beats Tae-soo. Tae-soo tries unsuccessfully to commit suicide so that his two friends can be together.

Meanwhile, in the present, Ji-hye falls for Sang-min in whom her friend Soo-kyeong is also very interested, but he seems not to notice. Then, in a sweet scene, they take shelter from the rain together under the same tree. He uses his coat to cover both of them and escorts her to where she needs to go. The moment, while magical, does not go anywhere as she feels his help was only due to his generous nature and not from any feelings for her on his part.

Back in the past, Joon-ha is guilt-ridden over his friend's attempted suicide and Joo-hee's own guilt. Determined to prevent any more hurt to her, Joon-ha joins the army and goes to Vietnam. There he loses his eyesight while he tries to retrieve the necklace Joo-hee had given him. When he returns to Korea, he meets again with Joo-hee, and, trying to hide his blindness, convinces her he has married in the hope she will move on with her life. Though heart broken that their relationship cannot continue, she does move on and eventually marries Tae-soo, Joon-ha's kind friend. After they have been married for several years and have a young daughter (Ji-hye) Joo-hee is approached by friends of Joon-ha, who relate Joon-ha's last wish: that his ashes be scattered by Joo-hee in the river, now a reservoir, where they first met. She then finds out that Joon-ha hadn't married, but he later did after Tae-soo and Joo-hee were married. She was told that he had a son also. The heart-break is too much and she cries.

In the present, Ji-hye's own story unfolds. Sang-min reveals his true feelings for Ji-hye - feelings that mirror her own. It is also revealed that their taking shelter together during the storm was no accident: he had purposely left his umbrella behind in a shop so that he could join her under the tree. Then, when Ji-hye pensively reveals her mother's story to him, tears stream down his face. Silently he lifts a necklace from around his neck and places it around hers. It is the necklace that Ji-hye's mother, Joo-hee, had given to Joon-ha when they met. The circle is completed: Joo-hee's daughter and Joon-ha's son have fallen in love.

Development[link]

Several of the school scenes were filmed at various universities in Korea. Notably, the library was in Kyung Hee University. There are many parallels between the flashback and present day stories. In the flashbacks, Joon Ha writes letters in the name of his friend Tae-soo to their mutual love interest. In the present day, Ji-hye writes letters in the name of her friend to their mutual love interest. In the flashbacks, Joo-hee has an annoying female friend that Joon-ha is initially set up with. In the present day, Ji-hye also has an annoying friend that interferes with her relationship. Also, Joo-hee and Ji-hye both receive the same poem from the people they love: "When the sun shines...".
