Videostandards
Videostandards are formal specifications that define the technical parameters for video signals throughout their life cycle from production to display. They establish common rules for aspects such as resolution, frame rate, color space, bit depth, compression, and transport, enabling interoperability between cameras, displays, encoders, decoders, and storage. Standards may apply to analog or digital signals and to broadcast, cable, streaming, or archival contexts.
Historically, videostandards began with analog systems such as NTSC, PAL, and SECAM used for terrestrial broadcasting.
Video colorimetry and metadata standards define how color information is represented. Common color spaces include Rec.
Key industry bodies include the International Telecommunication Union (ITU), the Society of Motion Picture and Television
