Object storage devices File-based storage does not inherently store information that is useful to a storage manager. Video files are unstructured data, as opposed to the structured data typically found in a relational database. A look at an MPEG video file reveals no information that would indicate whether it can be deleted or archived, or that it should be kept in nearline or online storage for immediate access. Such information as rights windows is kept in the right management database, and possibly the DAM system. This lack of important information at the file level leads to inefficient use of storage.
In contrast, object-based storage can encapsulate useful information with the media files as a media object. For example, information like keep forever, delete after a certain date when the rights expire, or not scheduled to play to air can be deleted from disk but maintained on the tape library. Currently, archive manager software and DAM implement these functions. For media needed for decades, encapsulating such information in an object makes more sense than with external applications, which may well not be around in the future. This moves more intelligence to the storage, which can interrogate objects to determine whether to retire or migrate aging data autonomously of any external applications.
Launching of large-scale online video portals requires a great deal of precision and accuracy at the design stage. In addition to complex infrastructure of a Web platform (the portal itself), we have to deal with a no less complex infrastructure video platform (as content delivery is only part of the platform). In this post, we will discuss some of the important principles of online video service design that we have learned over the five years of working on similar projects.
Comcast subscribers might have noticed that the company has been putting a lot of effort to grow its video-on-demand (VOD) library, adding huge amounts of new movies for rental and ad-supported TV shows for viewers to catch up on. What they probably didn’t realize is that the increase in content is just one part of a massive restructuring of its network architecture that is shifting delivery from more than 100 locally distributed VOD servers to a more centralized, IP-based delivery system.
Allegro DVT has unveiled the Genova turnkey OTT solution and proposed an integrated headend running on blade servers at IBC2011 in Amsterdam. The use of blade servers reduces the overall complexity of the system and makes routing, redundancy and administration simpler than in the past. The Allegro DVT Genova software headend is a fast deployable turnkey solution for WebTV and OTT which embeds licenses for: • Genova Live Transcoder, which provides live Web TV and OTT, to create a live multiscreen TV offer with playout on Adobe Flash, Microsoft Smooth Streaming, Apple HLS and WebM.
• Genova File Transcoder, which provides file-to-file batch assets conversion.
• Genova Fragmenter, which handles fragmentation and re-multiplexing of IP streams to commonly used Web TV and OTT formats.
• Genova Origin, a streaming server appliance.
• Genova Manager for redundancy and management.
• Support for single or distributed blade servers.
“Conductor” plays a key role in Sony's new Tapeless initiative called Media Backbone. Based on a Service Orientated Architecture (SOA) Media Backbone enables heterogeneous platforms and applications to be easily integrated and managed via a common Enterprise Service Bus (ESB). The benefits of an efficiently run, modular, scalable system are open-ended. A layered, abstracted system that can be viewed from a high level can be automated to an extreme degree, and integrated seamlessly with external services and consumers. Sony's experience with metadata-driven workflows is the key to integrating the proven benefits of SOA with a media production system.
"Spectrum is a network-based media management solution that combines on-the-fly high capacity file repackaging with powerful session based delivery and management of adaptive streaming video."

If you’ve ever wanted to create a streaming video site or add a video to server side, then you must have heard of FFMpeg and MEncoder. They are both famous open source projects and easy to get. Anyone can get these scripts at zero cost. However, some webmasters don’t want to be tied to a GPL or LGPL. So they try to find other server-side encoding solutions. These solutions are called as FFMpeg MEncoder alternatives or adobe flash media server alternatives, and most of these alternatives are commercial projects. I used to join in a video site creation work and have made lots of preparation work. Except for the known FFMpeg and MEncoder, I also searched some commercial projects and YouTube clones. For me, my budget is limited, so I choose affordable top one rank product in Google (the search term is “server-side video converter”). This commercial project is Sothink video encoder engine from SourceTec software. For the request of some friends, I process the experience into an article and make some comparisons of these three projects, which helps those people who want to create streaming video sites or add videos to server side choose the appropriate projects.
As computer systems evolve, the volume of data to be processed increases significantly, either as a consequence of the expanding amount of available information, or due to the possibility of performing highly complex operations that were not feasible in the past.
Nevertheless, tasks that depend on the manipulation of large amounts of information are still performed at large computational cost, i.e., either the processing time will be large, or they will require intensive use of computer resources. In this scenario, the efficient use of available computational resources is paramount, and creates a demand for systems that can optimize the use of resources in relation to the amount of data to be processed. This problem becomes increasingly critical when the volume of information to be processed is variable, i.e., there is a seasonal variation of demand. Such demand variations are caused by a variety of factors, such as an unanticipated burst of client requests, a time-critical simulation, or high volumes of simultaneous video uploads, e.g. as a consequence of a public contest.
In these cases, there are moments when the demand is very low (resources are almost idle) while, conversely, at other moments, the processing demand exceeds the resources capacity. Moreover, from an economical perspective, seasonal demands do not justify a massive investment in infrastructure, just to provide enough computing power for peak situations. In this light, the ability to build adaptive systems, capable of using on demand resources provided by Cloud Computing infrastructures is very attractive.

The day when we see a 5,000 channel universe inside the Pay TV operator walled garden, with consumers picking out their favourite Internet TV channels that are then listed under a ‘My Channels’ type tab in the existing TV programme guide, and where potential subscription fees flow directly to the service provider, could be closer than it looked. Infinite TV Exchange from NDS, launched today, provides the content marketplace that makes this realistic. Delivered in high quality video, the over-the-top (OTT) content would be presented as just another channel option in the TV-centric user interface viewers are already used to.
