Compression Standard Question:
Do you know instantaneous variable length codes?
Answer:
- 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.
