Streaming stored video


Media consumption experience have gone through tremendous changes at present days. Cable and satellite television, once the only viable means of accessing video content, is now just one option.

Streaming is nowadays popular more than traditional television thanks to an option of receiving an unlimited number of channels, films, serials and music tracks available for view at any convenient time of day. Stored streaming is the transfer of pre-recorded digital material from a remote source to users without making them download it first. It provides users with the ability to start watching the video while the file is still coming rather than forcing them to wait until the whole file has been downloaded.

Network Infrastructure for Streaming Stored Video

Infrastructure for streaming stored video consists in LANs, WANs, and internet. For this reason, typical LANS are used in a particular building or campus with excellent quality of video. However, in contrast to WANs that interconnects a number of LANs that result in higher delay and congestion. The Internet is a global network for streaming video content; however, it has problems of varying bandwidth and latency.

Network Topologies and Configurations for Optimal Performance

It goes without saying that topology and layout of streaming stored video have a substantial effect on its efficiency. Star topology usually works better due a centralized control point that makes it possible to manage traffic flows much easier. On the other hand, mesh topologies could work well in cases that demand a lot of redundancy so as not to lose the data or time. Packet size, transmission frequency, QoS, and routing protocol are other configuration considerations that have implications for network security architecture.

Bandwidth Requirements and Limitations

Streamed stored video performance depends on bandwidth. Banda width is dependent upon video resolution, numbers of simultaneous users, presence or lack of adaptive bit rate technology employed. For example, a consideration of available bandwidths on shared networks and usage caps imposed by ISP's to avoid buffering or reduction in quality. Striking a balance between bandwidth needs and constraints may require sacrifices, including lower resolutions or adaptive streaming.

Protocols Used in Network-Based Streaming

A number of protocols make it possible for streaming over a network; each having different characteristics. HLS is a streaming protocol developed by Apple which divides video files into short fragments and deliver these to clients using HTTP protocol. This involves adaptive bit rate streaming, dependent upon the available throughput of the network. Open standard that allows adaptive bit rate streaming with Dynamic Adaptive Streaming over HTTP (DASH) compatible with various devices, including smartphones. The developed by Adobe Real-Time Messaging Protocol (RTMP) is second to none when it comes to real-time transfer with relatively low lag but has not been accepted as much as it should compare HLS and DASH which are more adjusted for modern web architecture.

  • HTTP Live Streaming (HLS): HLS or HTTP live streaming is a protocol for streaming video on the Internet that was made by Apple and works with iOS, MacOS, iPadOS and TV OS platforms. This is a process where video files are divided into smaller parts and sent to the clients through HTTP. The adoption of this method enables one to easily integrate with the available web framework and efficiently uploads videos in a unified form on the Internet. Importantly, his provides for adaptive bitrate streaming whereby the quality is adjusted according to the networks status.
  • Dynamic Adaptive Streaming over HTTP (DASH): Another internet streaming delivery protocol is called DASH. In contrast to HLS, DASH is a multi-vendor standard driven by companies like Microsoft, Adobe, and Netflix. Working in the MEPG-DASH format, it allows for adaptive streaming bitrate and boasts of one of the most important benefits being its capability of supporting a big variety of OSes and devices.
  • Real-Time Messaging Protocol (RTMP): The real time audio/video protocol (RTMP) was designed by Adobe for this purpose. Adopted widely in different apps such as online games, social media broadcasting and on education platforms (for example, zoom and skype). As it utilizes the tcp connections it is known for having minimal latencies. The rise of HLS and DASH is partly responsible for the dwindling appeal of RTMP because these new standards are more compatible with contemporary web architectures.

Advantages of Streaming Stored Video

  • Increased Accessibility: The elimination of physical storage requirements enhances accessibility, making it easier for users to retrieve and enjoy content without the constraints of managing tangible media.
  • On-demand Content: Streaming stored video empowers users with the freedom to choose what to watch and when to watch it, liberating them from rigid schedules imposed by traditional broadcasting.
  • Increased User Experience: The superior quality of video and enhanced interactivity afforded by streaming stored video contributes to a more satisfying and engaging viewing experience compared to conventional broadcast methods.
  • Scalability: The scalability of streaming stored video is a pivotal advantage, allowing it to effortlessly adapt to the demands of large user bases. This scalability makes it a dependable solution for widespread video distribution.

Applications of Streaming Stored Video

  • Online Entertainment: Streaming stored video is widely utilized for online entertainment, granting users access to a diverse array of movies, TV shows, and other content via the internet.
  • Video Conferencing: In the realm of video conferencing, streaming stored video facilitates real-time communication between participants, enabling seamless and effective virtual meetings.
  • Education: Streaming stored video plays a crucial role in education, serving as a tool to facilitate online classes and lectures, providing flexible and accessible learning opportunities.
  • Corporate Communications: Within corporate environments, streaming stored video is a valuable asset for disseminating important information to employees and stakeholders, fostering efficient and transparent communication.
  • Advertising: Businesses leverage streaming stored video for advertising purposes, reaching target audiences with dynamic and engaging video content that can be tailored to specific demographics and preferences.

Challenges in Network-Based Streaming

  • Latency and Buffering Issues: However, latency as the lag between transmitting content and receiving it presents critical problems, especially in live streaming situations such as sports events. An additional problem is buffering problems that result in pausing or stuttering through a stream, culminating in the bad user experience and discontinuation of streaming.
  • Congestion Control Techniques: Congestion control techniques are also essential in managing network traffic during peak demand. This includes prioritising video traffic over other less time-sensitive data types such as QoS, assisting in the avoiding of latencies and packet losses.
  • Security Concerns: Piracy continues to be one of the key security problems as it affects authors of the content and legitimate providers of the services. Illegal distribution of copyright material threatens competitive pressure posed by pirate substitutes and other concerns such as those for user privacy and data breach are some issues bedevilling the streaming terrain.

Best Practices for Implementing Network-Based Video Streaming:

  • The Power of Content Delivery Networks (CDNs): The use of Content Delivery Networks (CDNs) is one way of ensuring high quality delivery of video contents. To improve latency and streaming experience, CDNs utilize distributed servers that replicate content closer to the end-users based on geographical positioning.
  • Quality of Service (QoS) Mechanisms: It is important to note that QoS measures play a pivotal role toward achieving fluent and enhanced streaming performances over networks. It employs traffic shaping, reservation of bandwidth, and congestion avoidance techniques to ensure high quality video traffic at the expense of other data type that are of lower priority.
  • Caching Strategies: How They Improve Video Streaming: Caching also entails keeping information that is frequently searched for near the end users thereby cutting off the journey of the searches in between various networks and retrieving the videos from local storage instead. Browser caching and server caching are techniques that improve loading times by making use of stored often accessed data and thus, enhances video streaming.

To sum up, successfully overcoming latency problems and buffering challenges while securing the system and embracing the recommended procedures will solve most problems encountered in network based streaming media. Combined, these strategies result in a better, stable video streaming quality.


In conclusion, addressing challenges in network-based streaming requires a comprehensive approach that includes mitigating latency and buffering issues, implementing effective congestion control techniques, addressing security concerns, and adopting best practices such as leveraging CDNs, utilizing QoS mechanisms, and implementing caching strategies. These strategies collectively contribute to an enhanced and more reliable video streaming experience.
