NAB Report Electronic Couch PotatoTM Integrates Video Quality IndexTM |
Distinctive for its application point in the network, the Electronic Couch PotatoTM (ECP) evaluates signals ready to be consumed by a subscriber. By connecting after a STB, it emulates an end user changing channels on the STB via a built-in infrared transmitter. The ECP then provides feedback on various service quality parameters to a central site. Now enhanced with Video Quality IndexTM, it provides real time evaluation of video quality that end users experience. Scanning all channels, the VQI identifies common video impairments such as macro-blocking, tiling and freeze frame, assigns each clip a Video Quality Index from 1 to 100, then combines them to a single, integrated metric. Results are consolidated across all channels and remote sites – making it easy to identify when and where video quality issues strike. |
