  • Methods for transmitting media data between terminals prior to transmitting acknowledgements during automatic connection negotiation
    Patent number: 8095669
    Abstract: Methods and products for reducing the time required to set-up a call are provided. In particular, new functionality to H.324 is added by allowing the transmission of media to commence after a reduced number of H.245 messages have been exchanged by two calling devices. If two terminals involved in a call are capable of automatic connect renegotiation, one or more predetermined logical channels in the two terminals for transmitting media is selected, a message is sent from one terminal to the other terminal to open the predetermined logical channel, and media transmission between the two terminals is commenced.

  • Methods for determining multiplex patterns
    Patent number: 7415047
    Abstract: Methods for determining multiplex patterns are provided. More particularly, a multidimensional data structure is used to store multiplex patterns and indexes used to access individual ones of those patterns based on audio channel selection, audio frame size, and what other media channels have frames pending. For example, when using a single audio channel, a two-dimensional look-up table maybe used to store multiplex patterns wherein one index is the audio frame size and the other index is an encoded value formed from bits representing whether any frames are pending for other corresponding media channels.
