For someone who like watching video, the most essential part of the video that appeals to them most varies from one to another. Someone would treat the quality of the video as the most critical part while others might not think so. Some might lay more importance on the speed of video playing for sacrificing some quality on the video. As long as the video quality is concerned, the topic of the article is brought up to discuss the difference of the video quality -- SD vs HD and what parameter the video quality is measured with.
Outlines of the Writing:
What is SD vs HD?
For most of us regardless of the specialists working on data process, the standards of the video can only be roughly regarded as high or low. Few of us knows the specifications of the video such as resolutions, pixels, frames and something like that. Here the SD and HD can roughly equate to the common standards and high standards. If you want to get into it, just follow the next part.
What is SD？
Standard-definition television can be shortened as SDTV or to be simplified as SD. It is a television system that uses a relatively low resolution and not considered to be either high or enhanced definition. Have you ever paid attention to the difference between the movies shoot in the earlier era and the movies shoot nowadays? The most recognizable part is the image quality of it. That well explains the difference between SD and HD. In the mid to late-20th century, "Standard" refers to the fact that it was the prevailing specification for broadcast (and later, cable) television.
What is HD?
HD normally refers to High-definition video (HDTV Video or HD video) with higher resolution and quality than standard-definition. HD conceptually implicates videos with high standards but there is no standardized meaning for high-definition. Generally, any video image with considerably more than 480 vertical scan lines (North America) or 576 vertical lines (Europe) is considered high-definition. 480 scan lines is the minimum standard of high-definition videos even though the majority of systems greatly exceed that. In some contexts, the images of standard resolution which are captured by a high-speed camera at rates faster than normal (60 frames/second North America, 50 fps Europe) may be considered high-definition.
Difference Between SD and HD
From the parts above, we know the most significant difference between SD and HD is the video standard or detailed as resolutions, pixels or vertical scan lines. For more specific comparisons between the two factors, you can check it here.
For many of us, 480p, 780p, 1080p and etc are just numbers. The way to measure the video quality is by comparing the number, the higher, the better. But that’s far from enough for us to learn the difference between them.
SD vs. HD Video: How they are compared?
Before comparing the SD and HD, we need to bring up another definition, pixel, which can be shortened as p. They are the little dots that make up an image, displaying its color. The number 1080 in 1080p refers to the pixels comprising the resolutions of the video. The more pixels imply the better quality of the videos.
Standard definition starts at 240p and ends at 480p which the high definition starts at. 1080p is full-strength HD while 720p is semi-HD. For the pixels higher than 1080p is regarded as ultra-HD.
SD vs. HD Video: Data and battery life
Before the use of Wi-Fi is popularized, people countdown to the amount of data which is included in the monthly mobile package. It is calculated that the burning of data for watching HD videos can be doubled or tripled as much as that of watching SD videos. And talking about the battery life consuming, all the video streaming has big impact on the mobile battery since the screen must be on continuously and the internet connections must be active. Streaming in higher definitions consumes more energy of the battery as they decode the video and further draining battery life.
