Improving IPTV QoE Taking the Suitable MPEG-2/MPEG-4 Quantizer Based on Jitter, Delay and Lost Packets Measurements
MPEG-2 and MPEG-4 encoding are standards that are widely used by the digital television industry. Although, nowadays, MPEG-2 is the most used, MPEG-4 is gaining ground because it provides good quality image with lower bandwidth consumption. The application fields where MPEG-4 can be applied are Digital Television, interactive graphical applications and interactive multimedia, while providing high audiovisual data compression to store or stream video and, at the same time, audio and video quality. MPEG-4 reduces the data rate in half, with the same image quality than MPEG-2.
