Quality of VoiceDetermining factors•Jitter
If packets arrive with lots of jitter, delay can be increased
•Packet LossMore than 10 % packet loss is noticeable.
•Latency A delay of over 100 ms is noticeable.
•CODEC More compression usually offers lower quality of voice
•Network Factors More utilization usually means more collisions
Tunable factors•Adaptive echo
cancellation•Tone detection and
generation•Voice activity detection•Silence suppression•Forward error correction•Tunable latency•Dynamic jitter buffer•Bad frame interpolation •Less bandwidth
utilization•Network priority
(Prioritize voice over data)

STB Plus Internet• The STB is not just at the convergence point between consumer
electronics and computing, but also communications. • The STB will in most cases serve three primary roles:
– A broadcast transmission receiver– A computing complement or substitute– A media device for home entertainment
Key Issues• Regulations and standards• Integrated circuits• Optimized configurations• Broadband and interactive services
Applications
•Streaming video
•High definition images
•Interactive TV
•Web TV
•Movies on demand
