Gigabit Video Interface
Gigabit Video Interface (GVIF) is a digital video serial interface developed by Sony in 1996 for high quality uncompressed video transmission from digital electronics, digital video hardware. It is intended primarily for automotive applications. It is compatible with the HDCP encryption system. GVIF transmits uncompressed serial data at speeds up to 1.95 Gbit/s. GVIF transmits over a single Differential signaling, differential pair; as a result, the cable is thin. Transmission distances up to ten meters are possible. Utilisation The GVIF bus was used circa 2000 onwards on many mid-range vehicles, including the Land Rover Discovery, Land Rover Discovery 3, Range Rover, some Lexus models, and the Toyota Prius. GVIF was primarily used to carry the video signal between the integrated satellite navigation unit and the in-vehicle display (also known as ''head unit''). In these vehicles, GVIF only carried video, despite the specification allowing for the transport of other inform ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Video
Digital video is an electronic representation of moving visual images (video) in the form of encoded digital data. This is in contrast to analog video, which represents moving visual images in the form of analog signals. Digital video comprises a series of digital images displayed in rapid succession, usually at 24, 30, or 60 frames per second. Digital video has many advantages such as easy copying, multicasting, sharing and storage. Digital video was first introduced commercially in 1986 with the D1 (Sony), Sony D1 format, which recorded an uncompressed standard-definition component video signal in digital form. In addition to uncompressed formats, popular Data compression, compressed digital video formats today include H.264 and MPEG-4. Modern interconnect standards used for playback of digital video include HDMI, DisplayPort, Digital Visual Interface (DVI) and serial digital interface (SDI). Digital video can be copied and reproduced with no degradation in quality. In contra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
