The Rollout of 3 Gb/s Infrastructures

This paper will review the evolution of digital infrastructures for broadcast television, explain how data is organized in the 3 Gb/s serial digital domain, and explore the possibilities that exist for this new infrastructure. An explanation of how the video/audio/data essence and metadata are organized in the serial data stream is provided for standard definition and high definition, including 1080p, as well as for 2× formats (left eye, right eye) for 3D television and “dual-link” production formats. The new 3 Gb/s infrastructure not only brings 3D television into the realm of possibility for broadcasters, but also includes 32 channels of embedded audio, a higher bit depth (12-bit) for video, an alpha or key channel with the program signal and the utilization of RGB color space for video production in television.
