A uniquely decodable code is a code where every encoded message sequence has only one valid decomposition into codewords. The video emphasizes that prefix-freeness guarantees this property, but the converse is not required; a code can be uniquely decodable without being prefix-free.
Conditions: Concerns decoding of concatenated codeword sequences at the receiver.; The video does not state a formal symbolic definition beyond the examples and prose.
