This paper presents the implementation of synchronized multimedia streaming for the Apple iPhone platform. The idea is to stream multimedia content from a single source to multiple receivers with direct or multi-hop connections to the source. First we look into existing solutions for video streaming on the iPhone for point-to-point architectures. After acknowledging their limitations, we propose a...
Receiver driven layered multicast streaming provides an attractive solution for transmitting the same video data to multiple receivers while accounting for the heterogeneity in the network resources and device capabilities. Traditionally, congestion control methods in receiver-driven layered multicast have used packet loss as a measure to detect congestion. However, given that wireless networks are...
Video streaming over wireless links is a challenging problem due to both the unreliable, time-varying nature of the wireless channel and the stringent delivery requirements of media traffic. Layered encoded video can be used to improve the system performance by adapting the sending rate for different video frame layers to the varying network and playout situations. In this paper, we study the adaptive...
This paper presents a lightweight but effective mastersender-driven multiple parent approach for online video adaptation and streaming to heterogeneous clients. The proposed design facilitates the cooperation of participating clients for improving the utilization of the spare resources in an overlay. Our design uses standard H.264/AVC video streams. It enables peers to contribute both CPU and bandwidth...
This paper proposes an efficient P2P-based video streaming scheme over the ADSL channel. To solve the problem of low down-link bandwidth utilization of the ADSL channel, the proposed scheme uses a new multi-peer aggragation (MPA) technique which is based on the many-to-one transmission mode. Besides that, with the help of an assistant peer selection method, MPA can also minimize the overall transmission...
A scheme that exploits the broadcast nature of the wireless communication in order to achieve multicast content delivery is presented in this paper. As opposed to broadcasting, this method enables the clients to determine on-line the delivered content, and thus preserves the advantages of an individual service. On the other hand, a multicast content delivery is much more efficient than a unicast content...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
