Video call capabilities in 3G mobile handsets and higher data rate in HSPA networks are fuelling resurgence in video telephony. This enables the delivery of exciting video applications to subscribers. The addition of Interactive Voice and Video Response (IVVR) opens up a wide stream of interactive video applications. In this paper we present a comparative study on the encoding tools and the techniques used to store and stream video on deman to subscribers. The paper presents the performance results obtained on a IP Multimedia Subsystem (IMS) based Next Generation Network test-setup connected to a live operator network. These results are based on the Quality of Experience (QoE) that end user perceive. These results can help service operators to deliver content rich applications to the end users as per their expectations.
