2022年12月2日 · There are several ways to output video and audio signals from a video source, including HDMI and SDI. Learn the difference between Standard HDMI, Mini HDMI, Micro HDMI, 3G-SDI, 6G-SDI, 12G-SDI, and Quad Link SDI.

Serial digital interface (SDI) is a family of digital video interfaces first standardized by SMPTE (The Society of Motion Picture and Television Engineers) in 1989. [1] [2] For example, ITU-R BT.656 and SMPTE 259M define digital video interfaces used for broadcast-grade video.

串列數位介面 SDI (Serial Digital Interface) 是現今許多電視、廣播、安全監控產業廣泛採用的數位影音介面，取代了過往的類比訊號，可進行快速且穩定的傳輸，不需考慮失真與干擾的問題。

2024年11月27日 · Serial Digital Interface (SDI) is a digital video standard for the broadcast industry. This standard is widely used in SDI encoders, SDI converters, and other equipment, including radio and television scenarios and security monitoring.

2024年10月30日 · 串行数字接口（serial digital interface，简称SDI）是一种用于传输高质量、未压缩的数字视频信号（也可嵌入音频）的接口标准。 它由电影与电视工程师协会（SMPTE，Society of Motion Picture and Television Engineers）组织制定，通常采用BNC接口的形式呈现，我们将符合这一接口标准进行传输的信号称为SDI信号。 简而言之，SDI是一种传输协议，而经过该协议进行数据传输的一种标准信号为SDI信号。 SDI信号以数字串行的方式传输数据，确保了视频信 …

Serial digital interface (SDI) is a standard for digital video and audio transmission over coaxial or fiber optic cabling. Speeds currently range from 270 megabits per second (Mbps) up to 12 gigabits per second (Gbps) for the latest standard released in 2015. The SDI standard uses data words that are 8 or 10 bits in length.

2025年3月21日 · What is SDI? And why is it still so relevant today when competing interfaces like NDI and HDMI are gaining more ground? This article goes a little deeper into the origins of SDI, its working applications, and what makes it still the standard in professional video production.

2023年10月1日 · SDI is a professional broadcasting industry standard. It transmits high-quality and uncompressed digital video over coaxial cables. Several versions of SDI signals are available. These include HD-SDI, 3G-SDI, 6G-SDI, 12G-SDI, and 24G-SDI. Each version supports different video resolution levels and data transfer rates.

Common SDI input/output standards on the market include HD-SDI, which supports up to 720p and 1080i; 3G-SDI, which supports 1080p up to 60fps; 6G-SDI, which supports 4K at 30fps; and 12G-SDI, which supports 4K at up to 60fps. We can also find SDI's technical standards such as SMPTE 292M, also known as HD-SDI, and SMPTE 424M, aka 3G-SDI, etc.

2022年8月3日 · Both HDMI and SDI cables transmit audio and video signals from a source to a display. The key difference between them is that SDI is a connection type more commonly used in professional video gear. In contrast, HDMI connectors are more frequently found on electronics aimed at consumers and prosumers.
