The distant address is an IP address if the correspondent doesn't have a subscription or is in the form: http://username.whmsoft.com if the correspondent has a subscription. - Start the program. - The Web Server only verifies the subscription name and password and gives the IP address to the correspondent. All the other program features are unchanged, in particular the end-to-end security. - The user must give the subscription name to the correspondent but not the password, because the computer IP address can be replaced by an other computer IP address which uses the same identifiers. ******************** *** Other Notes *** ******************** - Read carefully the documentation before starting (at least the generalities, the TCP/IP and the Anonymous Player chapters). - Minimum required configuration: Pentium II, 200 MHz. Minimum recommended configuration: Pentium III, 500 MHz. - In the Action sub-menu, there is an assistant for beginning quickly with the product. - WhStream is compatible with WhMic version 5.0 and above versions, with the common features. If many participants are planned, it is recommended to do some preliminaries tests with WhMic clients. - It is recommended to use a high speed modem (ADSL or cable) or the local area network for the audio communications. A 56K modem may be sufficient for the message sending, the file transfer and the anonymous reception. - It is recommended to use a version of DirectX superior or equal to the version 9.0. - Frequent synchronization problem messages or no simultaneous playing and recording constraint or bad sound quality: Increase the effect meters (program parameters). - Frequent display synchronization problem messages with spectrogram: Increase the "Spectrogram Reduction" parameter value. - In normal running mode and with the anonymous reception, to disable the treatments with the stereo files and URLs, the user can choose as driver parameters: - Number of channel(s): 1 - Channel(s) to treat: All - The provided DirectShow software filters (MPEG-2 and subpictures for the video, AC3 for the audio) allow reading, by choice, the DVD-Video volumes in mono, in stereo/dolby or in multichannel. The 3D output and the audio treatments are possible in mono and in stereo/dolby. ********************** *** License Prices *** ********************** See on the product web site. ******************** *** Enhancements *** ******************** - Addition of the WHM Audio Codec, a new and high performance voice codec, for the bi-directional communications. - Review of the WHM Audio Codec. This codec is from now a great quality and high performance codec for the voice and the music, in return for a simple change in some parameters. - Addition of the "TCP/IP Web Server Parameters" sub-menu allowing to have a distant address in the form: http://username.domainname ******************* *** Corrections *** ******************* Nothing.
