In addition to simply converting between SDI and HDMI, ATV's converter also has the ability of converting just the frame rate and outputting the same format as the input. For a frame rate converter, it is inexpensive, compact, and lightweight. Toei TV found that it was a perfect match for their needs. If the need was limited to the current situation, the unidirectional AV-3-SH
would have sufficed, but Toei TV choose the bidirectional AV-3-BD
for its versatility in the future.
