Apollo 11 mission had two modules
Lunar module - which descent to moon carrying two astronauts
command / service module- CSM was designed to
return astronauts from the
lunar surface on a direct-descent
mission to earth and splash down.
Direct telecast from the Command service module is not possible but CSM stored the recording of conversation which is transmitted by LM (which occur once in a rotation because the LM is stationary while CSM is orbiting the moon) then CSM sents to earth..

This is the actual camera used in Apollo
slow-scan television (SSTV) cameras,
running at 10 frames-per-second
(fps), produced only black and white
pictures and first flew on the Apollo
7 mission in October 1968.
NASA states as
The equipment onboard the Apollo
Command Module that was used to
make the recordings was called the
Data Storage Equipment (DSE). Its
contents were transmitted to the
ground periodically during the mission.
Also, the Command Module DSE had the
capability to record data live during
certain periods from the Lunar Module
as it flew separately in lunar orbit.
The equipment used aboard the Lunar
Module to make the recordings was
called the Data Storage Electronics
Assembly (DSEA). It made recordings
onboard the Lunar Module, but the
DSEA flown on the Eagle during Apollo
11 malfunctioned. As a result, many of
its recordings are barely, if at all,
audible, with a constant high-pitched
background tone. In the attached
database, the recordings that are
virtually inaudible are highlighted, but
they are available on the web to
ensure a complete release of the
recordings made during the mission.
The portion of
the broadcast spectrum traditionally
used for video was sending vital ship
data to Earth, and there was no room
left for the standard black-and-
white video format of the era: 525
scan lines of data at 30 frames per
second, transmitted at 4.5 MHz. So
Lebar helped devise a smaller "oddball
format" – 320 scan lines at 10 fps,
transmitted at a meager 500 kHz.
Tracking stations back on Earth would
take this so-called slow-scan footage,
convert it for TV broadcast, and beam
it to Mission Control, which would send
it out for the world to see.
a direct transmission signal from the
moon, NASA had to maintain stations
in three continents – two in Australia
(the Honeysuckle Creek Tracking
Station near Canberra and the Parkes
Radio Observatory surrounded by sheep
paddocks west of Sydney); one at the
Goldstone Deep Space Communications
Complex in the Mojave Desert of
California; and one at the Madrid
Manned Flight Tracking Site in Spain........ the tracking stations with a direct line on the Apollo 's signal were the ones in Australia. The 200-foot-diameter radio dish at the Parkes facility managed to withstand freak 70 mph gusts of wind and successfully captured the footage, which was converted and relayed to Houston.
