![]() Older streaming protocols like RTMP and RTSP are particularly unfriendly to wireless networks as they require a constant data stream at the stream bandwidth. It also allows streaming providers to leverage existing HTTP-based content delivery infrastructure. Prior to getting hot and heavy with wireless networks, I did a lot of streaming infrastructure implementation for Wowza’s customers (as many of this blog’s readers are well aware – just go look into the archives!) HLS, which was released with the iPhone 3Gs, is designed from the ground up to handle the highly variable bandwidth and delay conditions inherent to mobile connections on Wi-Fi and cellular, while delivering a good streaming experience to the end user. For those of us that work on wireless systems with a strong guest access component, the fine folks at Wowza Media Systems posted earlier this month about the inner workings of HTTP Live Streaming (Apple’s proprietary streaming protocol, or HLS) which accounts for about 45% of all streaming traffic – which tracks pretty closely to Apple’s market share of mobile devices.
