Why do we need Video Compression?

Standard Definition (SD) Video: 720x480 @ 30 frames/second (fps)
requires:
720 x 480 pixels 30 frames 3 colors
8 bits
---------------------- x -------------- x ------------ x -------- = ~250 Megabits/sec (Mbps)

Typical video delivery pipes

Compression Factor Required
Dialup Modem: 48 Kbps
~5000
ISDN: 128 Kbps:
~1900
T1: 1.5 Mbps:
~160
T3: 45 Mbps:

H.264 is leading default with similar quality at half the bit rate of H.263 or MPEG-2

Measuring / Monitoring Video Quality
Video Bit Stream
Target use case
• Ensuring content is “advertiser-friendly”
Goal
• Measure quality and quantify result
• Compare “score” against parameters
• If quality is in the “good” range, then video is useful
for advertisers
Analyzes the video content itself
• Not the “protocol”
• Not the “network”
• Measurement of the user experience

Slide 21
Logo Detection / Tracking
 Demonstration identifies the Dialogic logo within our corporate video
 Two-step process:
– Identify the logo (in different sizes, even if partially hidden)
– Track the duration of time the logo is visible
 Highlight the logo when it is recognized…
 … and keep track of number/duration of appearance
 In some cases (quick appearance, hidden) we will not recognize/track
the logo (not a useful appearance for advertising)

Digital Watermarking
 Most obvious application is to reduce piracy
 Also has applications in the enterprise space
– Ensuring authenticity of video delivery to your customers
– Tracking receipt of sensitive material to the intended audience
 Additional consumer applications
– Tracking what videos are being watched by a consumer
– Useful for rating services (what people have watched)
– Ad insertion/tracking (what advertising did people see?)
