Short serial broadcast -- you can bet on it! (9)

I believe the answer is:

totaliser

I'm a little stuck... Click here to teach me more about this clue!

'you can bet on it' is the definition.
I can't tell whether this defines the answer.

'short serial broadcast' is the wordplay.
'short' becomes 'tot' (both can mean a small alcoholic drink).
'broadcast' indicates an anagram.
'serial' with letters rearranged gives 'aliser'.
'tot'+'aliser'='TOTALISER'

Can you help me to learn more?

(Other definitions for totaliser that I've seen before include "System of speculation" , "you can bet on it!" , "Summer" , "Betting system" , "Risky system" .)

I've seen this clue in The Telegraph.
