We often use two nouns together (noun + noun) to mean one thing/person/idea, etc. For example: a tennis ball, a bank manager, a road accident, income tax, the city center.
The first noun is like an adjective - it tells us what kind of thing/person/idea, etc. For example:
A tennis ball = a ball used to play tennis.
A road accident = an accident that happens on the road.
Income tax = tax that you pay on your income.
The sea temperature = the temperature of the sea.
A London London
So you can say:
A television camera, a television program, a television studio, a television producer (all different things or people to do with television).
Language problems, marriage problems, health problems, work problems (all different kind of problems).
Compare:

A vegetable garden (a garden where vegetables are grown).
Often the first word end s in -ing. Usually there are things used for doing something. For example:
A washing machine
A frying pan
A swimming pool
The dining room
Sometimes there are more than two nouns together:
