The Sony HDVS high-definition video system was used to create content for the MUSE system, but didn't record MUSE signals. [2] It recorded Hi-Vision signals which are uncompressed. By the time of its commercial launch in 1991, digital HDTV was already under development in the United States.
Hi-Vision sets were very expensive, up to US$30,000 each, which contributed to its low consumer adaption. [18] A Hi-Vision VCR from NEC released at Christmas time retailed for US$115,000. In addition, the United States saw Hi-Vision/MUSE as an outdated system and had already made it clear that it would develop an all-digital system. [19]

Analogue video senders have the advantage of low manufacturing costs as the audio and video signals are simply modulated onto a carrier at 2.4 GHz or 5.8 GHz.They do, however, have the adverse effect of causing reduced bandwidth to local Wi-Fi networks and, in some cases, Wi-Fi networks can cause picture interference on the video sender signal.

TV 6 analog audio can be heard on FM 87.75 on most broadcast radio receivers as well as on a European TV tuned to channel 4A or channel C, but at lower volume than wideband FM broadcast stations, because of the lower deviation. Channel 1 audio is the same as European Channel 2 audio and the video is the same as European Channel 2A.
