Video Data Encoding & Decoding Systems

These systems are designed to encode and decode digital data within a composite PAL or NTSC video signal. They use the same basic principles employed by the Teletext data encoding and decoding systems in domestic broadcast systems.

The design of this system allows the video signal and encoded data to be transmitted, distributed or stored on recording media ready for data retrieval. This extremely versatile solution allows for permanent integration of digital data into a composite video picture image without superimposing graphical displays.
