Anyone who says engineering live field production is a breeze isn’t serious.
Online video advertising is booming but would grow even faster if quality could be improved and the impact of piracy reduced. A company’s brand image can be tarnished through association with poor quality reproduction and also when ads end up being shown against pirated content,
It pays to have a handle on your industry’s history. Today, few who write modern video software know that over $70 billion a year is generated in global broadcasting based on a non standards-based engineering decision made in 1953 when black and white television transitioned to color.
Pay TV operators and broadcasters struggling to measure viewing via mobile platforms could find help from firms specializing in analytics for wireless services. Birdstep of Sweden has signaled its intentions on this front by identifying video app and service providers as targets for the latest version of its analytics platform for measuring QoS across both cellular and Wi-Fi services.
The coding efficiency of audio compression is about to improve markedly because of a new MPEG audio standard—MPEG-H. This standard will permit many new and useful capabilities for those involved in television audio.
It is far too soon to write off the desktop as a major online video platform as it still accounts for twice as much viewing as tablets for long form content and four times more than smartphones, according to Adobe’s Digital Index (ADI).
IPTV is set for further substantial subscriber growth on the back of ongoing broadband roll out and increased capacity across most markets, according to several recent forecasts.
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.
