Blippo/CMBR/Week 9
In Blippo+, CMBR is a television network. This is about Week 9.
Transcript and technical details
As of Week 9, CMBR broadcasts a new audio signal along with the visual noise. This signal is encoded with the Slow-scan television method, in Robot format, a signal frequently used in amateur radio.
Five distinct signals are transmitted, corresponding to the regular day's programming. These signals are decoded into images into the following message:
ᴛʜᴇ ꜱᴏɴɢ ɪꜱ ᴛʜᴇ ꜱɪɢɴᴀʟ
Messages are transmitted with the following features:
- The text "#reson8" (or perhaps "**reson8") appears at the top left
- Notably, a user by the name of "reson8" appears multiple times on the Femtofax channel "Subspace Spotlight"
- A single, large word in block text dominates most of the image's dimensions
- Finally, at the bottom right, a text code is shown, which serializes the image (e.g. "1/5" for Celestial Snow and so on to "5/5" for Fleas & Fuzz)
The "Robot 8s BW" format seems to be used. Each image transmission takes 8 seconds, plus some time for header and footer. In this format, each image is 160 x 120 pixels, and is greyscale (see sstv-handbook.com) (although most images in these transmissions appear to be 1-bit black and white).
Each "show" in CMBR is 1 minute long. The "Morning" show is "Celestial Snow". In this show, the same image is transmitted 6 times. Another image is transmitted 6 times in the "Noon" show "Dance of the Ants", and so on.
The audio signals can be decoded into images using eg MultiMode Cocoa or MultiScan3B for Mac, Robot36 for Android.
The first four images ("Morning" to "Prime") are transmitted repeatedly in the clear. The fifth image ("Late" / "Fleas & Fuzz") however is transmitted with interference, differing in type with each transmission. This interference can be heard in contrast to the other four signals.
