Innovative Custom Logic Solutions for Video Production Environments
Video production equipment is used in television stations, cable, and satellite plants, within electronic news gathering vans, and in film and advertisement production environments. Production equipment includes video switchers, routers, and servers, professional video cameras and monitors, videotape recorders (VTRs) and video disk recorders (VDRs), video editors, and compression equipment.
Studios typically are equipped with means to receive global and local feeds. They also include production equipment for capturing live programming within the studio. The content from the feeds are stored and served for post production involving editing and adding audio and visual effects. Finally, a master control room in the studio is used to control and monitor the signal sent to cable operators.
Within the production environment, video and audio data are primarily transported in uncompressed format using the serial digital interface (SDI) standard defined by the Society of Motion Picture and Television Engineers (SMPTE). The equipment used supports standard-definition (SD) digital video formats, high-definition (HD) digital video formats, or both and uses a 75-ohm connection.
SD video is transmitted at SDI rates of 270, 360, or 540 Mbps; HD video is transmitted at the SDI rate of 1.485 Gbps. Recently, a new SMPTE standard was ratified to support 2.97-Gbps data rate that enables higher resolutions such as 1080p (full HD). With its superior visual quality, full HD video represents the future of digital video broadcasting. As a result, there is an increasing need for hardware that can handle the larger data throughput required when transmitting full HD video. Figure 1 highlights the equipment used in a typical video production setting.
