Voice&Video Engine for Media Phones:
smart terminal solution to bring HD voice and video over IP to innovative user devices
Why Carriers need a Media Phone?
Game changer for the telecom industry
The media phone is an absolute game changer for the telecom industry. For carriers putting such device into customers’ homes is similar to obtaining a 7-inch interactive advertising space in every household to offer numerous VAS. World’s top carriers have already recognized this trend, introducing innovative media phones. For example, have a look at iRiver Wave Home by Korea Telecom, Home Manger by AT&T or Verizon Hub.
Why High Quality Voice and Video for Media Phones is Essential?
IP voice and video calls are the most common media phone use case
Basically a media phone is a replacement for a traditional home phone. That means that to find popularity, the basic call functionality of the device has to be equal or better than that of traditional PSTN phones. Voice and video calls with media phones are IP-based. Securing high-quality VoIP on a shared inexpensive processor is a challenge for most OEM suppliers. SPIRIT’s TeamSpirit® Voice&Video Engine Embedded effectively solves this task, adding high quality real-time voice and video calls and conference functionality to media phones. The Engine deals efficiently with all the IP inherent network issues including echo, noise, packet loss, last mile congestion, etc., resulting in a superior multimedia user experience across carriers’ IP services.
Why Network QoS is Insufficient and Media Phone QoS is a Must?
Smart voice&video engine guarantees end-to-end quality for every call
IP-services can gain popularity only when they don’t lose to traditional ones in quality and functionality.
Carriers’ network specific QoS mechanisms alone are NOT able to guarantee end-to-end IP voice and video quality.
- For example, when both users are in the realm of the same well-managed carrier’s network, this network can be overwhelmed with heavy traffic (YouTube, torrents). Traffic competition deteriorates IP voice and video quality.
- As an essential part of communications happens cross-network, varying QoS in different networks, transit networks without guaranteed QoS and overloaded gateways usually cause quality degradation.
- Even in ideal case of well-managed carrier’s network end-to-end quality can be degraded because of the last mile difficulties, caused by low-quality terminal user equipment and user LAN settings (when multiple devices are connected to the same Internet channel).
That means that user terminals themselves must include proven voice and video processing software solutions to deal with IP-related issues of different origin at the terminal side, to complement and amplify network QoS.
SPIRIT’s Voice&Video Engine handles voice and video processing in media phones and takes care of each and every IP call quality. The Engine features wideband voice processing and hardware accelerators support for rich HD voice and video to secure customer satisfaction with communications part of carriers’ IP services.
