The rising adoption of video in the enterprise has organizations scrambling to meet business demands for high-quality video streaming and distribution. As an increasing number of corporations utilize video for communication, employee training, collaboration, and live event webcasting, they experience network inefficiencies and bandwidth congestion challenges that negatively affect the user experience.
This blog discusses what those challenges are and how VIDIZMO enterprise video platform helps solve those challenges.
The Prevailing Enterprise Streaming Video Challenges
Today, the most common video delivery challenges facing enterprises include:
- Quickly exhausting enterprise bandwidth when the entire company is tuning to watch a live broadcast or video conference at the same time
- Poor quality video streaming due to insufficient network bandwidth in remote corporate offices or branches
- Incessant video buffering and high latency during live events
- Costly investments in content delivery networks (CDNs) for video distribution
- Network congestion as a large number of people simultaneously access an on-demand video such as a mandatory training video
- Slow file transfers in low bandwidth networks, especially for large or lengthy video files as well as video file transfers over external networks or to external parties
- Geographically dispersed, mobile or remote employees and clients facing long delays while accessing online business video content
- Lack of video support or reliable video delivery on various user devices, including smartphones and tablets
VIDIZMO, a Gartner recognized enterprise video content management system, offers businesses a comprehensive solution to all enterprise video streaming (both live and on-demand streaming), storage, management, and distribution challenges in a consolidated video platform. For efficient video delivery on all user devices and in all bandwidth conditions.
VIDIZMO employs a variety of WAN (wide area network) acceleration techniques and other overarching technologies that optimize enterprise bandwidth and ensure smooth and reliable video delivery for live and on-demand video content over the internet or across the enterprise network or intranet.
VIDIZMO provides a complete solution with the following technologies that optimize streaming video delivery in all different deployment scenarios in the cloud, on-premises or hybrid model.
How You Can Solve Enterprise Live Video Streaming Challenges?
WAN Optimization and Edge Caching
VIDIZMO provides a range of WAN acceleration techniques to enable smooth video streaming while also optimizing bandwidth consumption and significantly reducing the amount of traffic needed to traverse over the WAN connections. For live and on-demand video content, VIDIZMO utilizes content delivery networks (CDNs) to accelerate video delivery and performance while also managing any surges in internet traffic. Depending on user locations, CDNs have a distributed set of edge servers that optimize video delivery to users in remote offices/ branches or edge-of-network locations anywhere around the globe.
The closer the CDN edge server is to the end-user geographically, the faster the content will be delivered to the user. That way, CDNs quite literally move content to the ‘edge’ of the internet, i.e., in closest proximity to the users, resulting in reduced load on the origin server, distributed network traffic, minimal WAN bandwidth consumption, reduced latency and buffering, as well as faster video startup time.
In case of on-demand videos, for instance, a CDN caches the video when it is first requested by a user as it stores the video’s replicas on multiple servers around the ‘edge’ of the internet. After that, when the video is requested by others users in the same network, the requests are served by a nearby edge server rather than a remote origin server. The CDN does this by redirecting the user request from the origin server to a server in the CDN that is closest to the end user that delivers the cached video content. Alternatively, on-demand videos can also be pre-positioned to the edge servers during off-peak hours, thereby reducing network workload in prime work hours.
To distribute live or on-demand streaming video over the internet across the world, VIDIZMO uses Microsoft Azure, Verizon & Akamai CDN – one of the world’s most extensive content distribution networks with the point of presence (PoP) around the globe. For organizations that are already partnered with a CDN provider, VIDIZMO provides seamless interoperability with all major CDN providers offering third-party network optimization technologies, including Riverbed, Blue Coat, Cisco WAAS, as well as peer-assisted or P2P CDNs, in addition to providing its own eCDN Server Software.
For instance, VIDIZMO integrates with Riverbed solutions, to enable users to view and share videos by reducing the impact of video bandwidth consumption over the WAN using Riverbed SteelHead™ technologies, resulting in a stellar live and on-demand video experience for all employees.
It does this by using WAN optimization techniques such as content caching, data compression, latency reduction, Quality of Service (QoS), and packet coalescing. Leveraging such powerful WAN optimization solutions in combination with VIDIZMO can dramatically reduce video bandwidth utilization by as much as 98%. (Source: Riverbed) [1].
Similar results are also achieved using VIDIZMO’s eCDN Server Software and edge-caching appliances.
VIDIZMO SD eCDN
While a public CDN addresses challenges associated with video delivery over the internet across the world, enterprise networks may still face network and bandwidth challenges that hamper video experiences in-house or across a company’s intranet. Such problems arise mainly because of small incoming internet bandwidth pipes installed on-premises or in the case of live broadcast sessions, which involve a large number of people viewing a video concurrently in the same location. VIDIZMO provides multiple solutions to enterprises faced with such challenges.
One of the solutions include installing VIDIZMO’s software-defined enterprise content delivery network (eCDN) and edge-caching appliances in each bandwidth-congested location to replicate one incoming stream into thousands of streams within a local area network (LAN). As a result, viewers receive video content from a VIDIZMO eCDN edge-caching server in proximity to their location – all while incurring reduced bandwidth costs and efficient load distribution.
Adaptive Bitrate Streaming (ABS) and HTTP Streaming Protocols
Adaptive bitrate streaming is a technology designed to deliver the highest possible video quality ‘adapted’ or adjusted to various user devices and network conditions. The process involves videos (delivered using modern protocols discussed below) encoded at multiple bitrates or quality levels created for all screen sizes (or user devices). During playback, the user’s bandwidth availability and network quality determine which quality level provides the optimal playback experience. Any changes in network quality or the internet connection are accommodated by corresponding adjustments to the video bitrate or quality. With such dynamic adjustments to video quality, ABS also minimizes any instances of buffering while providing high-quality playback.

With VIDIZMO, all videos are encoded into five or more different bitrates and four formats with a total of up to 20 renditions. Typically, a 1080p uploaded video is encoded into 1080p, 720p, 480p, 360p, 240p bitrates to ensure playback on all devices, browsers in all bandwidth conditions. During playback, VIDIZMO’s player dynamically adjusts the video quality to match the user’s available bandwidth or network quality in real time – all of which ensures quick video initialization, minimal buffering, and a smooth video playback in both high or low bandwidth connections. Using ABS, users can stream both live and on-demand videos to various devices on any web server while conserving bandwidth
VIDIZMO support all types of ABS implementations in different HTTP streaming protocols, including Apple’s HTTP Live Streaming (HLS), Adobe’s HTTP Dynamic Streaming (HDS), Microsoft’s Smooth Streaming as well as MPEG-DASH, an open standard protocol for adaptive video streaming over HTTP.
With ABS, VIDIZMO also ensures high-quality video delivery on mobile devices. Additionally, VIDIZMO offers dedicated mobile applications for both Androids and iOS devices to enable mobile video capture on smartphones and tablets, which further supports an organization’s bring your own device (BYOD) policies for video capture and delivery.
Choice of Progressive Streaming with Legacy Protocols
Over the years, the growth and expansion of the video ecosystem has led to the development of various contemporary HTTP streaming protocols now used as an alternative to or in combination with legacy streaming protocols. However, despite the prevalence of HTTP streaming, progressive streaming still holds its prominence and is still widely used in various corporate scenarios.
For users with a need for legacy streaming protocols, VIDIZMO provisions Adobe’s Real Time Messaging Protocol (RTMP) for Flash-based video streaming, Microsoft’s Microsoft Media Streaming (MMS) for use in various Windows Applications as well as Real Time Streaming Protocol (RTSP). Custom streaming protocols like RTMP, RTSP, and MMS enable users to maintain a persistent connection to the streaming server, with predictable latency. Additionally, custom protocols allow the user to skip and start playback from any part of the video, with minimal bandwidth waste. All this while, network congestion is minimized as all video traffic is offloaded from the primary corporate WAN to prioritize delivery of high-priority data.
VIDIZMO provides users the flexibility to use any streaming protocol that best fits their needs. This way, VIDIZMO leverages advantages inherent in both legacy or contemporary streaming protocols, depending on a customer’s specific video streaming and infrastructure challenges.
By default, we use progressive download, ABS and pubic CDN to optimize video delivery, but other options can be added to coexist with the default options to optimize video delivery for different locations. VIDIZMO provides a combination of solutions to suit varying customer needs and to create the most optimized solution for the customer's environment and infrastructure. The aforementioned technologies are not mutually exclusive options for implementation and we also offer software customizations to fit specific customer needs.
