Bridge Intros Objective QoE
OSLO -- At IBC 2013, Bridge Technologies is launching Objective QoE, a new monitoring technology for Quality of Experience (QoE) monitoring. In a break with tradition Objective QoE eschews the conventional approach to QoE monitoring, by using only criteria that are appropriate to broadcast and digital media delivery.
Objective QoE monitors a range of errors that typically occur in media delivery, including audio silence, colour freezes, colour black, and freeze frames, to detect failures affecting quality of experience. This contrasts with the traditional approach taken in many QoE systems, which are based on criteria derived from telephony, such as MOS (Mean Opinion Scores) and arbitrary values such as ‘bluriness’.
“The problem with QoE monitoring to date is that it has been highly subjective, and therefore less useful than it should be,” said Simen Frostad, chairman of Bridge Technologies. “Using MOS to evaluate video delivery does not provide a precise or valuable asessment of QoE. Based on MOS and ‘bluriness’, a full HD transmission of the Superbowl would score highly, while a transmission of Casablanca – in black and white, and with the blur and scratches of an old movie – would score badly. Objective QoE provides a far superior solution that actually delivers data and alerts that media operators really need.”
Bridge Technologies’ Objective QoE is an agile, view-anywhere solution that fits any monitoring strategy thanks to the capabilities of the new VB288, an advanced server-based content extraction system with virtual videowall displays giving operators visual QoE verification of large numbers of HD channels simultaneously, from any location. Content extraction can also be implemented on individual Bridgetech probes or groups of probes with the new content extraction software option, to provide additional QoE monitoring of local terrestrial and unencrypted satellite services.
