Abstract
A beacon signal including image information and an application to cause acknowledgment of receipt of the beacon signal is transmitted in order to measure approximate latency in transmission over a communication link that exhibits latency such as a packet switched digital network. Transmission latency for image information for an image included in a web conference is then estimated and elapsed time after transmission of such image information is measured and an indication provided to a presenter or conference monitor when the image should be visible to a conference participant which can be easily selected by the presenter.
Claims20
A method for synchronizing presentation of content of a web conference over a real-time communication link with content over another communication link which includes data latency, said method including
- transmission of a beacon message containing image data and software for transmitting an acknowledgment of receipt of said image data to determine approximate latency time of said another communication link,
- sending a web conference image,
- determining elapsed time subsequent to said sending of said web conference image, and
- displaying an indication to a web conference presenter when said elapsed time equals or exceeds a time corresponding to said approximate latency time.
Apparatus for conducting a web conference comprising
- a transmitter to transmit an audio portion of said web conference over a communication link,
- a transmitter to transmit image information of said web conference over another communication link exhibiting latency,
- a generator to transmit a beacon signal over said another communication link,
- a processor to determine approximate latency of said beacon signal in said another communication link,
- a timer for measuring elapsed time from transmission of said image information, and
- a display, responsive to said timer for indicating when said elapsed time equals or exceeds said approximate latency.
A method for synchronizing presentation of content of a web conference over a real-time communication link with content over another communication link which includes data latency, said method including
- configuring a data processor to provide a transmitter to transmit image information of said web conference over another communication link exhibiting latency,
- configuring a data processor to provide a generator to transmit a beacon signal over said another communication link,
- configuring a data processor to provide a processor to determine approximate latency of said beacon signal in said another communication link,
- configuring a data processor to provide a timer for measuring elapsed time from transmission of said image information, and
- displaying, responsive to said timer, an indication of when said elapsed time equals or exceeds said approximate latency.
