Information processing apparatus and method, and, program

A program for causing a computer to function as:

• a synchronization cancellation unit configured to cancel synchronization between synchronization timing of a network to which image data are transmitted and synchronization timing of the image data, on the basis of a delay time of image data transmission,
• an adjusting unit configured to adjust synchronization timing of the image data of which synchronization with the synchronization timing of the network is cancelled by the synchronization cancellation unit;
• and
• a synchronization connection unit configured to synchronize the synchronization timing of the image data, which is adjusted by the adjusting unit, with the synchronization timing of the network.

An information processing apparatus in a system including a first video transmission sequence having a video synchronization acquisition function and a second video transmission sequence, comprising:

• a synchronization cancellation unit configured to cancel synchronization between synchronization timing of a network to which image data are transmitted and synchronization timing of the image data, on the basis of a delay time of image data transmission according to the first video transmission sequence;
• an adjusting unit configured to adjust synchronization timing of the image data of which synchronization with the synchronization timing of the network is cancelled by the synchronization cancellation unit;
• a synchronization connection unit configured to synchronize the synchronization timing of the image data, which is adjusted by the adjusting unit, with the synchronization timing of the network;
• and
• a control unit configured to operate the second video transmission sequence different from the first video transmission sequence, using synchronization timing generated from the first video transmission sequence.
