Outlook on Mobile IPTV - Definition /25 SOC 컨퍼런스 2008 Mobile IPTV is a technology that enables users to transmit and receive multimedia traffic including television signal, video, audio, text and graphic services through IP-based the wired and wireless networks with support for QoS/QoE, security, mobility, and interactive functions. Through Mobile IPTV, users can enjoy IPTV services anywhere and even while on the move.
Outlook on Mobile IPTV - Approaches IPTV Mobility Mobile TV IP Access network is agnostic /25 (WLAN, WiMAX, Celluar) (DMB, DVB, MediaFLO)
Mobile IPTV Ongoing Standards – ITU-T Wireless network characteristics: The characteristics of a wireless network expressed in terms of current available bandwidth, packet loss and possibly other to-be-defined wireless network information parameters for a specific wireless link type e.g. WLAN, Cellular, WPAN or WMAN. The IPTV architecture is recommended to allow the delivery of IPTV services over different access networks (e.g. cable, optical, xDSL, wireless) The IPTV architecture is recommended to allow the delivery of IPTV services to any IPTV terminal device (e.g. mobile phone, PDA, set-top-box). The IPTV architecture is recommended to adapt dynamically to change in wireless networks characteristics when the service is delivered over a mobile network (e.g. bandwidth, packet loss rate, etc. The IPTV architecture is recommended to support device mobility that allows a mobile device to maintain its ongoing IPTV services while freely moving around. The IPTV architecture is recommended to support content delivery in several yet optional versions to be selected according to the capabilities of the IPTV terminal device receiving the content (e.g. access rate, resolution, supported formats, etc.). /25
Mobile IPTV Ongoing Standards – ITU-T The IPTV architecture is recommended to support the ability to identify wireless network characteristics information sent by the IPTV Terminal. The mobile IPTV terminal device is recommended to support service continuity. The mobile IPTV terminal device is recommended to be able to extract its own wireless network characteristics from the current wireless network. In case an IPTV TD is mobile, it is recommended to support mobility functionalities for service continuity when in motion. An optional signaling architecture for exchanging wireless network characteristics between an IPTV TD (mobile device) and DNG (or Service Provider Server). It allows DNG (or Service Provider Server) to adjust their sending rate for ongoing video service according to the received information (e.g., bandwidth, packet loss, etc.) from the IPTV TD. Piggybacking the information on the existing IP based Protocol is available. /25
