What does SDTV refer to in television terms?

SDTV refers to Standard Definition Television. This term is used to describe television systems that have lower resolution compared to high-definition (HD) formats. Standard definition typically includes resolutions such as 480i or 576i, which are adequate for older television displays but do not provide the enhanced clarity and detail seen in high-definition broadcasts.

Understanding the concept of Standard Definition Television is crucial, especially when discussing the advancements in broadcasting technology and how it contrasts with HD and Ultra HD formats. As the industry has progressed, many viewers have transitioned to higher resolution formats for a better viewing experience, making knowledge about SDTV important in recognizing the evolution of television technology.
