Performance evaluation of distributed video coding with different channel encoding techniques

Abstract

Most recently, the low density parity check codes are chosen as the channel encoding method to encode the Wyner-Ziv frames in distributed video coding. These codes involve much complicated encoding and decoding algorithms, and might increase the processing time of the system. In this paper, we use the codes with simpler encoding and decoding algorithms, the Reed Solomon codes, and compare the performance of both codes in encoding the Wyner-Ziv frames. The proposed model is verified with the addition of white Gaussian noise. The simulation shows that the output video sequence is of acceptable quality compared to the current model with the low density parity check codes. The proposed model is also more efficient as the results could be obtained in a shorter time.
