M迅播影院www.xunbo.xyzatthew’s life is devastated after the disappearance of his younger brother, Tom. Matthew’s father had left him to look after Tom and now Matthew feels responsible. His father is trying to hold back the anger and the blame but the cracks are beginning to show. One day Matthew is looking through a box of press clippings and video tapes about Tom’s disappearance. Suddenly he hears a ghostly voice on one of the video tapes telling him “you never came for me!”. It’s the voice of his missing brother. He shows the tape to his father, Jake. This time there’s no voice and Jake flies into a rage as the wound is reopened. Matthew tells his best friend Simon about the voices on the tape. Is he losing his mind, is Tom alive or dead? At home, Matthew plays the tape and hears Tom’s voice again, desperately pleading for help. Then Matthew sees Tom at the window, gaunt and haggard. He rushes out to Tom but no one is there… Matthew strikes up a friendship with next-door neighbour Amy, who is beautiful but troubled. He talks to her about Tom and she suggests he visits a local medium. Matthew is unsure but he is again haunted by nightmarish visions of Tom. When he tries to sleep he has recurring nightmares that he is being buried alive. In desperation he goes to visit Melissa, the medium, who tells him that the area has been cursed through the ages. Her daughter gives Matthew a present, the drawing of a young girl. The following day Matthew is shocked when he finds out that Simon’s sister, Sophie, has been abducted. Matthew realises that the drawing by the medium’s daughter is of Sophie. The hauntings escalate, Matthew’s state of mind deteriorates. Only Amy seems to believe him, as a tentative romance grows between them. Matthew knows that he needs to get to the bottom of Tom’s disappearance if he is ever going to save Sophie. There is no going back as he hurtles towards the stark, chilling truth… The Disappeared…you can’t bury the past.
（1）高清（High Definition），是我们目前相对比较熟悉的一个词语。高清是在广播电视领域首先被提出的，最早是由美国电影电视工程师协会(SMPTE)等权威机构制定相关标准，视频监控领域同样也广泛沿用了广播电视的标准。将“高清”定义为 720p、1080i与1080p三种标准形式，而1080P又有另外一种称呼—全高清（Full High Definition）。关于高清标准，国际上公认的有两条：视频垂直分辨率超过720p或1080i;视频宽纵比为16：9。
（2）标清（Standard Definition），是物理分辨率在720p以下的一种视频格式。
（3）超高清（Ultra High-Definition），这是我们今天的重点内容。来自国际电信联盟(International Telecommunication Union)最新批准的信息显示，“4K分辨率 (3840×2160 像素)”的正式名称被定为“超高清Ultra HD(Ultra High-Definition)”。同时，这个名称也适用于“8K分辨率(7680×4320像素)”。CEA要求，所有的消费级显示器和电视机必须满足以下几个条件后，才能 贴上“超高清Ultra HD” 的标签：首先屏幕最小的像素必须达到800 万有效像素（3840×2160），在不改变屏幕分辨率的情况下，至少有一路传输端可以传输4K 视频，4K内容的显示必原生，不可上变频，纵横比至少为16:9。 与此同时，电视行业里，同对高清电视机命名为HDTV一样，对于4K电视机的命名，美国消费者电子协会针对4K电视进行了一个官方的命名UHDTV，这个命名也就是超高清电视。
Ps: 720p格式，分辨率为1280×720p/60Hz，行频为45kHz 。
4K分辨率是1080p的4倍3840×2160 = 1920×2×1080×2
8K分辨率是4K的4倍7680×4320 = 3840×2×2160×2
