IPTV service is one of the topics where industry and academia are providing more efforts with the purpose of enhancing the systems in existence. One of the potentially biggest advantages of IPTV is the existence of a return channel from the customer to the IPTV service provider, which makes this technology the upcoming TV distribution system. The next big step is to serve stereoscopic video over IP networks. In this paper, we evaluate the stereoscopic video transmission over IP by taking measurements of the bandwidth, delay and jitter. These measurements are useful to test the QoS and QoE of the ITPV service and to demonstrate the need for high-performance stereoscopic compression codecs. Then, we study the performance of four free codecs in order to propose an algorithm to perform the appropriate decisions to transmit stereoscopic video in the IPTV network properly. The algorithm is based on the empirical data obtained from our test and on some analytical considerations. Finally, we show the impact on the network given by the algorithm, and we compare the QoS parameters when each codec is chosen.
