Moving to a 4K production environment requires a network with sufficient performance capability, but what does that mean?
The media industry is rapidly adopting file-based workflows in all stages of the content lifecycle including transcoding, repurposing, delivery, etc. Additional complexities could be introduced during media transformations, which if not handled properly, could lead to issues in video perceived by the end consumer.The issues are due to errors caused by media capturing devices, encoding/transcoding devices, editing operations, pre- or post-processing operations, etc. A significant majority of video issues nowadays are due to the loss or alteration in coded or uncoded video information, resulting in the distortion of the spatial and/or temporal characteristics of the video. These distortions in turn manifest themselves as video artefacts, termed hereafter as video dropouts. Detection of such video quality (VQ) issues in the form of dropouts are gaining importance in the workflow quality checking and monitoring space, where the goal is to ensure content integrity, conformance to encoding standards, meta-data fields and most importantly, the perceived quality of the video that is ultimately delivered. This end video quality can certainly be measured and verified using manual checking processes, as was traditionally the case. However, such manual monitoring can be tedious, inconsistent, subjective, and difficult to scale in a media farm.
Automated video quality detection methods are gaining traction……..
This paper discusses various kinds of video dropouts, the source of these errors, and the challenges encountered in detection of these errors.
The Switch is a U.S. based media operator offering local metro and long distance video transport services in major cities across the U.S., the United Kingdom, and Canada, to broadcast networks, production houses and major sports leagues. Among the various video transport services available to customers The Switch offers local on-demand connectivity, which has become a great success due to the company’s on-demand service model and easy, customer-controlled provisioning. The service was previously used by various media companies to connect internally between different geo- graphical sites and also to connect externally with companies offering complementary services, such as post-production houses. The success of The Switch’s metro service gave rise to the next logical step – to interconnect the isolated, local metro services and roll this out to more cities all over the country.
After NAB 2015, The Broadcast Bridge’s Frank Beacham talked with Devoncroft president Joe Zaller about current trends in the media and broadcast industry.
While the Television industry has been well served by SDI Baseband technology including routers, coax cable and BNC connectors, new IP-based video/audio infrastructure and workflows are promising far more flexible and cost-effective solutions in the future. However the new IP-based world must still interoperate with and build upon existing Baseband technology. This Lawo / Arista Networks White Paper explores a practical technology solution: A Software Defined Video IP Network using Lawo¹s Encapsulators, Gateways and Edge Processors, integrated with Enterprise-level high performance IP switching from Arista. The combination promises to advance and automate Television work-flows to meet near and long term demands of production, contribution, distribution and content delivery… and do it cost effectively.
High Efficiency Video Coding (HEVC) is the latest and certainly an efficient compression standard targeted at today’s high pixel count images.
Of all the crucial requirements often mentioned about storing data, permanence is the most important when it comes to archival storage.
Millennials under 35-years-old are driving a gradual transition from viewing broadcast television to online video that is expected to radically change global video viewing habits in less than ten years.
