Data communication (HUFFMAN CODING)

UNIT – 6 Image and Video Compression Techniques Huffman code, Run-Length Encoding, Relative Encoding, Lempel-Ziv Encoding, Real-Time Interactive Audio/Video, RTP, HTTP, and WWW. HUFFMAN CODING Example • Say we want to encode a text with the characters a, b,…, g occurring with the following frequencies: a b c d e f g Frequency 37 18 29 13 30 17 6 Fixed-Length Code a b c d e f g Frequency 37 18 29 13 30 17 6 Fixed-length 000 001 010 011 100 101 110 code • Total size is: (37 + 18 + 29 + 13 + 30 + 17 + 6) x 3= 450 bits Variable-Length Code a b c d e f g Frequency 37 18 29 13 30 17 6 Variable- 10 011 111 1101 00 010 1100 length code • Total size is: 37x2 + 18x3 + 29x3 + 13x4 + 30x2 + 17x3 + 6x4 = 402 bits • A savings of approximately 11% Constructing a Huffman Code g,6 d,13 f,17 b,18 c,29 e,30 a,37 Constructing a Huffman Code g,6 d,13 f,17 b,18 c,29 e,30 a,37 Constructing a Huffman Code 19 f,17 b,18 c,29 e,30 a,37 g,6 d,13 Constructing a Huffman Code f,17 b,18 19 c,29 e,...
