摘要

Video streaming for IPTV is transferring to wireless mobile devices. This process poses questions of the video quality that will result and the suitability of the existing pseudo-streaming schemes for video transfer. This paper sets out the case for wireless broadband video streaming based on a simple negative acknowledgment (NACK) scheme, which for convenience is called broadband video streaming (BVS). The paper shows that provided the roundtrip time is limited then BVS has the better features of UDP transport and standardized Datagram Congestion Control Protocol (DCCP). For single link exchange, BVS is also superior to multiple DCCP connections in terms of video quality, though the use of multiple connections bring adequate wireless channel utilization. Thus, assuming content caching close to the broadband wireless access network then simple BVS is worthy of future elaboration.
