The proposed algorithms rely on theoretical calculations to estimate the bit rate necessary for the successful decoding of Wyner-Ziv frames without the need for a feedback channel, which makes the system suitable for broadcasting applications. Additionally, in regions where H.264 intracoding outperforms Wyner-Ziv coding, the system automatically switches to intracoding mode in order to improve the overall performance. Simulations results show a significant gain in the average PSNR that can reach 3\u2009dB compared to pure H.264 intracoding, and 0.8\u2009dB compared to fixed-GOP Wyner-Ziv coding.<\/jats:p>","DOI":"10.1155\/2009\/319021","type":"journal-article","created":{"date-parts":[[2009,1,12]],"date-time":"2009-01-12T15:35:18Z","timestamp":1231774518000},"page":"1-11","source":"Crossref","is-referenced-by-count":8,"title":["New Adaptive Algorithms for GOP Size Control with Return Channel Suppression in Wyner-Ziv Video Coding"],"prefix":"10.1155","volume":"2009","author":[{"given":"Charles","family":"Yaacoub","sequence":"first","affiliation":[{"name":"Engineering Department, Faculty of Sciences and Computer Engineering, Holy-Spirit University of Kaslik, P.O.
