The 7E Talking Head family includes the TH-1, TH-2, and (coming soon) the TH-4 (H-264 for ISDN or IP). The TH-1 can be used with 64 or 128 kbps ISDN. The 7E Talking Head TH-1 VideoPhone is shown with HNS-9201 BGAN (left) but can be used with GAN terminals also (see bottom right). Two GAN terminals can be used in 128 kbps mode with a S0DA DU0 Multiplexer.

The TH-1 contains an adjustable 6.4" TFT display and speaker integrated into a tough waterproof case adequate for cables, microphones, and headphones. The TH-1 offers H.263 realtime video or high quality 7.5kHz audio and low speed pictures. A simple mixing facility on the unit enables low-Z microphones and balanced or unbalanced line sources can be connected simultaneously. An I/O processor optimizes the audio/video for transmission and provides both professional XLR/BNC and domestic phono connections. Headphone jack sockets provide direct and cue (return) signals for monitoring purposes. The unit requires 90-264VAC 47-400Hz or 10.8-14.4V VDC (remote control requires two AA batteries). Related Equipment: Tandberg Tactical II and Tandberg Tactical MXP.

VIDEO RENTAL EQUIPMENT: We rent the Talking Head by 7E. It can be used with both 64 and 128 kbps ISDN over terrestrial or satellite-based networks. If two Inmarsat M4 terminals are being used, it is necessary to use a multiplexer such and the S0DA Duo by 7E to achieve 128 bit performance. The TH-1 can also be used with a single HNS-9201 or Thrane & Thrane EXPLORER^TM 500 to achieve 64 kbps ISDN-based video.
