ATP620 Teletext Inserter
The ATP620 is a broadcast quality teletext generator and inserter capable of storing up to 1000 pages in battery-backed memory. It can also be used for combining incoming services, capturing teletext pages from up to six teletext sources and storing the captured pages in memory before re-transmitting them.
The unit has two serial inputs for page updating, each capable of running at up to 57600Baud. The second port can also provide a connection via a modem.
It can transmit up to 8 streams of teletext data on a maximum of 17 VBI lines on odd and even fields. Data lines not used for transmission can be set to regenerate or blank the data being received on the video input. The time can either be set and incremented locally or decoded from an incoming teletext channel.

Service Combining
One of the unique features of the ATP620 is the ability to decode and capture pages from one of the six teletext inputs.
The range of pages to be captured on each magazine for each input can be set on the front panel or via the serial line. This gives the unit the ability to capture part of a magazine from one service, combine it with local pages and then transmit it all as a single service on the output.
No other device on the market can provide this level of flexibility.
