HVM0002C01

5. GLOSSARY

3G

A term used to refer to 1080 line, progressive scan television systems with a serial
interface bitrate of approximately 3Gbit/s.

3G/HD/SD-SDI

3G/HD/SD - Serial Digital Interface for high definition or standard definition digital
television capable of transmitting bitrates of 2.970Gbit/s, 2.967Gbit/s, 1.485Gbit/s,
1.483Gbit/s and 270Mbit/s.

AES

Audio Engineering Society. International professional society dedicated to the
promotion of research and advances in audio technology. Their webpage is:
www.aes.org

ATC

Ancillary Time Code. Ancillary data packet inserted into the digital video signal for
transmission of VITC or LTC information.

BNC

Bayonet Neill-Concelman connector.

CRC

Cyclic Redundancy Check. Coding used to confirm the bitstream integrity. For
3G/HD-SDI signals each line of video includes coding for confirmation that the line
content is correct.

DVB-ASI

Asynchronous Serial Interface. An asynchronous serial interface for DVB streams that is
one of the principal formats for transmission of MPEG-2 streams over cable.

EDH

Error Detection and Handling. A system for detection of errors in SD-SDI signal
transmission. It consists of the insertion of a CRC (Cyclic Redundancy Check) packet at
the end of each video field to check the data in that field. The receiving equipment
calculates the CRC for the data received and compares it with the CRC received in the
packet to determine if errors are present in the transmission.

GPI

General Purpose Input. This is a signaling and control interface that receives
information through detection of the open or closed status of an external circuit. The
information is received from a device at the other end of the line, typically employing a
GPO interface.
