OBJECTIVES:
The student should be made to:

• Understand error–control coding.
• Understand encoding and decoding of digital data streams.
• Be familiar with the methods for the generation of these codes and their decoding techniques.
• Be aware of  compression and decompression techniques.
• Learn the concepts of multimedia communication.

UNIT I         INFORMATION ENTROPY FUNDAMENTALS                                                                 9
Uncertainty, Information and Entropy – Source coding Theorem – Huffman coding –Shannon Fano coding – Discrete Memory less channels – channel capacity – channel coding Theorem – Channel capacity Theorem.

UNIT II          DATA AND VOICE CODING                                                                                            9
Differential Pulse code Modulation – Adaptive Differential Pulse Code Modulation – Adaptive subband coding – Delta Modulation – Adaptive Delta Modulation – Coding of speech signal at low bit rates (Vocoders, LPC).

UNIT III         ERROR CONTROL CODING                                                                                           9
Linear  Block  codes  – Syndrome  Decoding  – Minimum  distance  consideration  –  cyclic  codes  –
Generator Polynomial – Parity check polynomial – Encoder for cyclic codes – calculation of syndrome
– Convolutional codes.

UNIT IV       COMPRESSION TECHNIQUES                                                                                        9
Principles – Text compression – Static Huffman Coding – Dynamic Huffman coding – Arithmetic coding – Image Compression – Graphics Interchange format – Tagged Image File Format – Digitized documents – Introduction to JPEG standards.

UNIT V       AUDIO AND VIDEO CODING                                                                                             9
Linear Predictive coding – code excited LPC – Perceptual coding, MPEG audio coders – Dolby audio coders – Video compression – Principles – Introduction to H.261 & MPEG Video standards.


OUTCOMES:
Upon completion of the course, the student should be able to:

• Design an application with error–control.
• Use  compression and decompression techniques.
• Apply the concepts of multimedia communication
