Abstract

The present invention provides a transmission apparatus and a transmission method. The transmission apparatus configured to transmit moving image data to another apparatus inputs moving image data and, if some of the input moving image data is to be excluded from the moving image data to be transmitted according to a transmission state, excludes the moving image data of a frame not corresponding to an event out of the input moving image data from the moving image data to be transmitted.

Description

technical field [0001] The present invention relates to an apparatus and method for transmitting moving picture data. Background technique [0002] Conventionally, a technique called frame skipping is known. According to this frame skipping technique, when moving image data is transmitted in real time, frames to be transmitted can be deleted according to the communication status. US Patent Publication No. 2004 / 0105494 discusses a method of blocking some frames when transmitting moving image data to a plurality of receiving devices. These frames are blocked according to the communication frequency band used when communicating with each receiving device. [0003] However, if this method is used, important frames may be deleted by frame skipping. Contents of the invention [0004] The present invention aims to reduce the possibility of deleting important frames due to frame skipping. [0005] According to an aspect of the present invention, there is provided a transmittin...
