Bandwidth Optimization

Save bandwidth and storage.

Split screen comparison of video quality outputs from an HD ProRes Transcode to MPEG2 @50MB/s input. The 9 MB/s encode provides comparable quality to the 15 MB/s encode but at a lower bitrate to conserve bandwidth.

Advantages of 9.25 Mbps

To navigate the ever increasing demand for content to more devices, reduced bit rate encoding is a first step to optimize bandwidth and storage, freeing up vital assets to offer more expanded premium packs and store more content.

Simply put, advancements now allow operators to deliver TV streams encoded at 9.25 Mbps allowing 4 simultaneous HD streams to be transported over 1 QAM.  When you run the numbers, this equates to approximately 38% QAM and storage savings over 15 Mbps. 

At reduced bit rates, quality standards must be maintained.  Since we encode from master source files of 50 Mbps or higher, outputs are at a much higher quality and comparable to 15 Mbps.

With reduced bit rate encoding, you can leverage your existing QAM infrastructure to transport and store more HD content and create new monetization opportunities, without investing in CapEx.   

Advances in Optimized ABR

The Deluxe OnDemand Lab has been testing new video streaming technology that reduces bitrates for IP-based live or VOD services while improving video playback quality.  This new QBR™ technology from MediaMelon, optimizes ABR by means of rapid scene analysis, content characterization, perceptual quality mapping and advanced buffer management techniques. This results in lowering bitrate requirements for video streaming by 35% on average while also reducing content quality variance by an average of 86% and thereby eliminating video artifacts.

QBR technology intelligently goes beyond current adaptive bitrate schemes to significantly improve quality and bitrate performance — providing a dramatic advantage that content owners and video service providers can employ in conjunction with the Deluxe OnDemand OneWorkflow to enhance the viewing experience while utilizing streaming infrastructure more effectively.   This paves the way for streaming of full HD and 4K UHD video across today’s bandwidth-constrained IP networks, without the need to re-encode content or alter the existing video workflow.
