Head-End Analyzer

1. Deep Pixel-by-Pixel Headend Solution

• Deep pixel-by-pixel video content analysis – not just video stream

• Accurately detects source content issues and headend errors – major issues impacting ALL customers

• No-reference and full-reference configurations

2. Scalable CPE Offering• Lightweight agent for PC, STB, gateway, etc• Complete end-end coverage of last mile & home – STB or

Home Gateway - Up to 75% of problems• Proactive monitoring vs reactive probe-based solutions• Most scalable solution for end-end coverage

– Scales as CPEs are added– No extra hardware, management costs

3. Unique Correlation Capability• Single view of video quality as perceived by end-user• Pre-encrypted deep content analysis correlated with post-

encrypted network header analysis to determine impact of impairments on video content

• Industry’s most accurate assessment of end-user QoE - determines impact of network impairments on content

4. Exclusive V-Factor Score• Simple MOS score (1-5) to represent subjective

quality• Easy to understand, report, aggregate
