whitepaper TCP Streaming for Low-Delay Wireless Video2006-06-16 01:00:27 Institute of Electrical and Electronics Engineers
  With the penetration and popularity of mobile devices such as pocket PCs and smart-phones, there is an increasing need of low-delay video streaming over wireless channel. Traditionally, UDP (User Datagram Protocol) is used for video streaming. However, due to unreliable transmission and fluctuating bandwidth of wireless channel, this requires error concealment and recovery mechanisms which greatly increases the complexity and delay of the system. Furthermore, UDP streams are often more difficult to penetrate firewalls. This paper proposes using TCP (Transmission Control Protocol) for video streaming due to its ease of use, reliability, and flexibility in selecting frames to transmit.   
whitepaper Costs and Benefits of Fading for Streaming Media Over Wireless2005-06-25 Hewlett-Packard
  This paper discusses some salient aspects of the wireless channel, and the challenges and opportunities they pose for streaming media. In particular, the time-varying fading nature of the channel means that it is inherently unreliable, but also that significant throughput improvements are possible when scheduling is coupled opportunistically with channel fluctuations. Together, these characteristics mean that solutions designed for media distribution in wired contexts do not directly translate into appropriate wireless solutions. This paper discusses how channel, source, and application-dependent concepts such as multiuser diversity, opportunistic and collaborative communications, loss-tolerance, and differing application-dependent delay constraints can be exploited to pose new and useful constructs for streaming media over wireless.

whitepaper Digital Video Hacks: Record a Streaming Video2005-06-23 O'Reilly Media
  One can't always sit and watch a streaming video from beginning to end. When the stream is live, this becomes a problem, because a person can't pause the stream and have it start where he or she left off. Using VLC, one can save the stream and watch it at his or her convenience.

whitepaper Join-Distinct Aggregate Estimation Over Update Streams2006-12-09 01:00:18 Association for Computing Machinery
  There is growing interest in algorithms for processing and querying continuous data streams (i.e., data that is seen only once in a fixed order) with limited memory resources. This paper proposes the first space-efficient algorithmic solution to the general Join-Distinct estimation problem over continuous data streams (the techniques can actually handle general update streams comprising tuple deletions as well as insertions). The estimators are probabilistic in nature and rely on novel algorithms for building and combining a new class of hash-based synopses (termed "JD sketches") for individual update streams. The authors demonstrate that their algorithms can provide low error, high-confidence Join-Distinct estimates using only small space and small processing time per update.   
whitepaper Power-Efficient Streaming for Mobile Terminals2006-06-16 01:00:27 Association for Computing Machinery
  Wireless Network Interface (WNI) is one of the most critical components for power efficiency in multimedia streaming to mobile devices. A common strategy to save power is to switch WNI to active mode only when network activity is expected. In streaming systems, this approach is problematic because data are typically received continuously. One solution is to transmit data packets as bursts, which leaves WNI more time between bursts in standby mode. However, that subjects bursty transmission in high peak rates, which leaves it prone to congestion. This paper studies theoretically and empirically the impact of burst length and peak transmission rate for observed packet loss and delay characteristics as well as potential energy savings in a Wireless Local Area Network (WLAN) environment.   
whitepaper Link Adaptation and Cross-Layer Signaling for Wireless Video-Streaming in a Shared Medium2006-05-12 01:00:28 Institute of Electrical and Electronics Engineers
  Changes in the quality of wireless links impose great demands on video codecs and underlying network layers when seamless video-streaming is to be achieved. Moreover, it is not enough that only the video codec or only the radio adapts to these changes; the efforts should be applied in both layers, and - if possible - synchronized. So, on the one hand, a responsive link adaptation method should be employed in the radio. And, on the other hand, the video codec should be able to follow the changes in the maximum throughput due to wireless link performance variations. This paper presents the results of video-streaming over 802.11a link in the presence of background traffic, generated by other stations sharing the same medium.   
whitepaper Smooth Stream Technology in Hitachi Hard Disk Drives2006-10-27 01:00:16 Hitachi
  Hard disk drives developed for use in personal computers are now being used in Audio/Video devices such as MP3 players and personal video recorders. AV systems play and record streams of data. If the stream is interrupted, the interrupt may result in missing audio or video information. In AV applications, there is no advantage to streaming data faster than the AV device requires. Data must be delivered consistently at the required rate. As a result, it may be better to have some small segment of incorrect data delivered in the stream than to have a long delay. This new Streaming Command Set was developed for ATA drives, which allows AV products to change drive behavior to meet AV system requirements.
