Explain instantaneous variable length codes. - Compression Standard

Explain instantaneous variable length codes.

- A code that maps source symbols into a set of variable number of bits.

- A VL code compresses the sources and decompresses with zero error.

- By implementing a right coding strategy, an identically distributed source might be compressed almost close to its entropy.

- This process is in contrast to fixed length coding methods.

- Examples of variable-length codes are Huffman coding, LempelZiv code.
