Transmission apparatus, transmission method, and program

A transmission method comprising:

• a sequentially acquiring frame images drawn in a frame buffer;
• a sequentially encoding encoding units each corresponding to part or whole of one of the frame images and generating image data;
• a sequentially transmitting the image data;
• a estimating, after the transmission of the image data, a transmission failure probability that is a probability of failure of the transmission of the image data;
• and
• a determining, in reference to the transmission failure probability of the image data, one or a plurality of referents that serve as a referent of a given encoding unit, from among the encoding units related to the image data transmitted,
• wherein, in the encoding, the given encoding unit is encoded by referring to the one or the plurality of referents, and the image data is thereby generated, and
• the transmission failure probability is estimated using a number of response-waiting transactions, an effective bandwidth of a communication path for image data, and an elapsed time from a start of transmission of the image data to a current time.

A non-transitory computer-readable medium configured to, when programmed by circuitry, perform the following process:

• sequentially acquiring frame images drawn in a frame buffer;
• sequentially encoding encoding units each corresponding to part or whole of one of the frame images and generating image data;
• sequentially transmitting the image data;
• estimating, after the transmission of the image data, a transmission failure probability that is a probability of failure of the transmission of the image data;
• and
• determining, in reference to the transmission failure probability of the image data, one or a plurality of referents that serve as a referent of a given encoding unit, from among the encoding units related to the image data transmitted,
• wherein, in the encoding, the given encoding unit is encoded by referring to the one or the plurality of referents, and the image data is thereby generated, and
• the transmission failure probability is estimated using a number of response-waiting transactions, an effective bandwidth of a communication path for image data, and an elapsed time from a start of transmission of the image data to a current time.
