Agan-agan JBTV kali ini kami akan memberikan penjelasaan tentang standar resolusi televisi.
Banyak sekali jenis serta ukuran grafis layar tv yang digunakan sesuai merk maupun dukungan teknologi lainya. Masing-masing punya keunggulan serta kemampuan yang berbeda sesuai dengan fungsi peralatanya. Berikut ini ukuran standard resolusi layar televisi yang umum digunakan dan sudah dikelompokkan berdasar teknologinya :
| Name | Dimension (w x h) | Pixels (*) | Keterangan | |
|---|---|---|---|---|
| QCIF | 176 x 144 | 4:3 (**) | 24.8 k | Quarter Common Intermediate Format – Standard for video conferencing systems. |
| CIF | 352 x 288 | 4:3 (**) | 99.0 k | Common Intermediate Format – Standard resolution for video conferencing systems to convert from PAL to NTSC or vice versa. Width and Height is a multiple of 16 to simplify the MPEG encoding (full image can be divided into 16×16 MPEG macroblocks). |
| NTSC (DV) | 720 x 480 | 4:3 (**) 16:9 (**) |
338 k | NTSC is a composite video standard, mainly used in US, Canada, Japan and South Korea. DV is a standard resolution for digital video recording in consumer products according NTSC standard. The DV resolution uses a multiple of 16 for width and height to simplify the MPEG encoding. Thus the number of lines is reduced from 486 to 480 compared with D1. |
| NTSC (D1) | 720 x 486 | 4:3 (**) 16:9 (**) |
342 k | NTSC is a composite video standard, mainly used in US, Canada, Japan and South Korea. D1 is a standard resolution (defined by SMPTE group) for professional video recording with NTSC standard. |
| NTSC (4:3) | 720 x 540 | 4:3 | 380 k | Necessary resolution to display NTSC (D1/DV) video in 4:3 format by using square pixel. Alternatively, 640 x 480 are used to display NTSC video. |
| PAL (D1/DV) | 720 x 576 | 4:3 (**) 16:9 (**) |
405 k | PAL is a composite video standard similar to NTSC, mainly used in Europe, Asia and Australia. Since the width and the height of the PAL resolution is a multiple of 16, there is no difference between D1 and DV format. |
| PAL (4:3) | 768 x 576 | 4:3 | 432 k | Necessary resolution to display PAL (D1/DV) video in 4:3 format by using square pixel. |
| NTSC Widescreen | 864 x 486 | 16:9 | 410 k | Necessary resolution to display anamorphic NTSC (D1/DV) video in 16:9 format by using square pixel. |
| DVCPRO HD 720 |
960 x 720 | 16:9 (**) | 675 k | Digital Video Cassette PROfessional – SMPTE Standard D12 in 720 p with up to 100 MBit/s. |
| PAL Widescreen | 1024 x 576 | 16:9 | 576 k | Necessary resolution to display anamorphic PAL (D1/DV) video in 16:9 format by using square pixel. |
| HDTV 720 | 1280 x 720 | 16:9 | 900 k | High Definition Television with 1 M Pixel. |
| 1366 x 768 | 16:9 | 1.00 M | Popular resolution for LCD TVs with 1 M Pixel. | |
| DVCPRO HD 1080 |
1280 x 1080 | 16:9 (**) | 1.32 M | Digital Video Cassette PROfessional – SMPTE Standard D12 in 1080i with up to 100 MBit/s. |
| HDV | 1440 x 1080 | 16:9 (**) | 1.48 M | High Definition Video – standard format for consumer HD digital video with pixel aspect ratio of 1.33. The video is stored by using MPEG-2 compression. |
| AVCHD | 1440 x 1080 | 16:9 (**) | 1.48 M | Advanced Video Codec High Definition – standard format for consumer HD digital video with pixel aspect ratio of 1.33. The video is stored by using MPEG-4 (H.264) compression. |
| D4 | 1440 x 1024 | 4:3 (**) 16:9 (**) |
1.41 M | Unimportant format for non-realtime recording of high-resolution digital video as four D1 frames. |
| HDTV 1080 | 1920 x 1080 | 16:9 | 1.98 M | High Definition Television with 2 M Pixel. |
| D16 | 2880 x 2048 | 4:3 (**) 16:9 (**) |
5.63 M | Format for non-realtime recording of high-resolution digital video as sixteen D1 frames. |
* Jumlah pixel : 1 k = 1024 dan 1 M = 1024 k = 1048576
