Abstract
This invention provides an apparatus capable of performing time slip playback even upon occurrence of a network trouble. This invention relates to an apparatus which, when a network trouble occurs, acquires, of multimedia data, a point representing the position of multimedia data which has already been transmitted to a network, and after the network recovers, transmits multimedia data subsequent to the point to the network.
Claims20
An apparatus which transmits multimedia data to be played back to a network, comprising:
- means for, when a trouble of the network is detected, stopping transmission of the multimedia data;
- means for acquiring a point representing a position of the multimedia data obtained when transmission of the multimedia data is stopped;
- and
- means for retransmitting the multimedia data to the network from the point acquired by the acquiring means.
