[edit] Technology
SightSpeed uses a proprietary algorithm for video compression. The video conferencing technology is capable of transmitting 30 frame/s video, and uses the standards-based H263 codec.
SightSpeed's video codec was originally developed at Cornell University's Discover Lab and is based on H263.
SightSpeed's network technology is SIP based.
[edit] Features
- SightSpeed users are able to have free video calls with each other.
- Video Mail messages can be sent to any e-mail address.
- The SightSpeed software is able to host video conferences with up to nine participants.
- "Phone Out" is the name of the service that allows users to make phone calls to landlines and mobile phones, paying with pre-paid credit. "Phone In" allows SightSpeed users to receive phone calls from regular telephones.
[edit] Limitations
The main criticisms are:
- Lack of true privacy features such as encryption.
- SightSpeed "Phone Out" does not support outbound caller ID in the United States, where people commonly reject calls from unrecognized numbers. The recipient sees "unknown" or a blank field instead of the caller ID number.
- Though it uses the SIP standard it is not interoperable with SIP networks and can only be used with a SightSpeed account.
