Exploring New Technologies for Non-Destructive Adjustment of Running Times of File Based Content

A generation ago, a 60 minute broadcast program slot was filled with a fairly static mix of program material, commercials, and other content. That all changed beginning in the late 1990's, when the number of minutes of non-program material began inching up, and by 2013 had increased to more than 14 minutes of every hour. — This change resulted in tens of thousands of previously produced episodes and other material no longer fitting into the program block, and left broadcasters with two not-so-great choices for adjusting the running time of original programming: cut scenes out, or use destructive baseband re-timing options. — Today, there are sophisticated algorithms that utilize modern GPU video processing and transcoding techniques that can re-time content with virtually no decrease in video or audio quality. — This paper will focus on the history of content re-timing for broadcast, and delve into the legacy and modern technologies for re-timing.
