The advantages, disadvantages, and rules of existence between legitimate and pirated versions are a big topic, and the so-called “; Genuine&# quo;, It is an audio-visual product obtained through legal channels and published and distributed by a legitimate audio-visual publishing and distribution institution registered with the Ministry of Culture& Ldquo; Genuine” In addition to works that contain domestic copyright, they also include" Imported Original” And&quo; Introduction version”. This commonsense website has summarized several experiences in the audio and video industry to help disc enthusiasts distinguish between genuine copies

Ten Methods to Identify Genuine CDs
1. [Look at the label]
All genuine CDs have circular laser anti-counterfeiting stickers issued by the Ministry of Culture. In the early years, they were small stickers, but now the new ones are large stickers (legal imported originals, as introduced in the Chinese image, also have this label, and there is also a Chinese label paper attached to the outside) The one with the signature cannot be said to be 100% genuine, but the one without it is basically not genuine. The specific identification method for labels can be found in Appendix 1
2. [Watch Varieties]
Many well-known films in China have not yet been released on genuine DVDs, such as the “Lord of the Rings” series, “Star Wars” series, “Godfather” series, “Forrest Gump”, “Brokeback Mountain”, “Six People”, “24 Hours”, and so on. Therefore, if you see these films on a certain website or store, you can basically conclude that they are selling pirated versions
3. [View Version]
Large Xinhua bookstores generally do not sell pirated versions, and legitimate copyright agreements usually have uniqueness, that is, a variety will only be distributed by one manufacturer (excluding the public version), D5, D9; Simple and boxed; The silver and gold versions are only a few versions, so if you see a version that is different from a large Xinhua bookstore or can be determined to be genuine, such as a completely different packaging, different number of discs, and different distribution institutions, it can be basically concluded that it is a pirated version. It is rare for manufacturers to replace the packaging of the same version during its release period

4. 【 Look at manufacturers 】
There are legitimate manufacturers, such as Zhonglu Warner, Zhonglu Dejiala, Taisheng, Zhongkai, Meijiaren, Feishi, Donghexing, etc. There are pirated manufacturers: 5K, Red Dragon, Pegasus, Jintuo, Chuangjia, MAC, UPS, UFO, Focus, Kirin, Dijing, Zuobao……
5. 【 Look at prices 】
The main cost of legitimate copies lies in copyright fees, so there may be significant differences in pricing between different manufacturers and films. A D5 can be as cheap as 5 yuan, while an expensive one over 20 yuan is normal. On the contrary, if a seller sells all kinds of D5s at the same price and D9 at the same price, it can be concluded that it is not legitimate because the pricing system for legitimate copies is completely different
6. [Ironing is an ironclad proof]
Genuine editions never ironing codes (the so-called ironing code is the SID code left by the production line that intentionally irons out the inner ring of the disc), because there is no problem of being afraid of tracing the production source in genuine editions, which is completely different from the popular ironing code in pirated editions. However, not all genuine discs have visible codes on their inner rings

7. 【 Look at the material 】
Cross regional collage of materials is a popular practice in the piracy industry, such as: French Zone 2 screen+Hong Kong Zone 3 subtitles; The original version does not have this concept, such as the US Zone 1 screen and Zone 6 national configuration, so seeing such a display can basically be concluded as piracy. For TV dramas, as long as you see the words HDTV on the screen, don’t think too much. 100% pirated, this type of disc is directly produced by capturing TV signals
8. 【 Packaging should not be trusted 】
Genuine piracy is not related to the level of exquisite packaging. Do not consider the packaging to be genuine, and rough packaging is considered piracy. The main cost of authenticity lies in copyright fees, and piracy does not have this cost. Therefore, piracy at the same price can make the packaging very good. Similarly, those old films that have already become public, such as the Kurosawa series, old European classics, and so on, Due to the lack of copyright fees or extremely low copyright fees, legitimate copies can be sold for 5 yuan per copy, which is cheaper than many pirated versions
9. [Image quality chucks are not based on]
CDs are digital technology, and piracy does not reduce image quality due to copying. Similarly, as long as a good disc base is used, the disc will not get stuck.
. Therefore, the quality of the image and whether it is stuck cannot be used as a basis for judging the authenticity. The quality of the picture mainly depends on the quality of the film source, A digital version of a DVD that underwent digital restoration and careful production 30 years ago (frame by frame scanning of film, then synthesizing static images into a dynamic video, commonly known as the disc version) can achieve the same image quality as a new DVD made using glue to magnetic technology (using digital camera equipment to directly convert dynamic light and shadow, commonly known as the film version, shadow version, or analog version, but not the gun belt, which is a pirated patent). The production cost of the digital version is two orders of magnitude higher than that of the film version, so most domestic low-cost films, even Hong Kong and Taiwan films, are made from adhesive to magnetic DVDs. Pirates will never scan the film themselves to make digital DVDs, they will only use legitimate digital film sources that have already been made, so these films with only adhesive to magnetic versions are not clear whether they are genuine or pirated
10. [Genuine versions also have compressed discs]
HDD is commonly known as&quo; Compressed Disk” Or&quo; Economy DVD&# quo;, It can be played on a regular DVD player using DVD as the medium, using MPEG-1 or MPEG-2 encoding. The low bitstream allows each disc to accommodate up to 7 hours of programs (i.e. 8-10 episodes of TV dramas), with a slightly higher or equivalent image quality than VCD, which is a significant difference compared to regular DVDs. Many legitimate manufacturers have been launching compressed discs since the second half of 2004, and the trend is gradually gaining popularity. Audiences in developed countries enjoy 1280× When high-definition videos started with 720 resolution, Chinese people were still intoxicated with 320× 240 is a compressed disc with VCD level image quality. It should be emphasized that regardless of whether MPEG-1 or MPEG-2 encoding is used, once the bitstream falls below the normal VCD bitstream (i.e. video 1.15Mb/s), the image quality immediately decreases significantly and is unbearable. This is why a large number of D9 compressed discs (one disc holds over 20 episodes) have extremely poor image quality. Generally speaking, D5 can accommodate 7 hours and D9 can accommodate 13 hours, which is the maximum capacity of a compressed disc while maintaining the VCD image quality level
