Information processing apparatus, method, and program
The present invention relates to an information processing apparatus, a method, and a program capable of suppressing deterioration of content quality. An integrated reception buffer time adjustment unit 114 obtains a maximum transmission delay time that is the longest delay time among the transmission delays of data transmission performed by each reception unit 113 . The reception buffer time setting unit 208 calculates a reception buffer time using the maximum transmission delay time, a transmission delay time of the data transmission by the reception unit 113 , and a prescribed reception buffer time. The reception buffer time setting unit 208 sets various delay times and waiting times such as a variable compression encoding delay time, a redundant encoding block reception waiting time, an ARQ retransmission packet waiting time, and a network jitter handling buffer time from the reception buffer time. The present invention can be applied to an information processing apparatus, for example.

the setting means sets, as the parameter of the process, a variable compression encoding delay request time necessary when the encoded data rate-controlled and generated at the encoding is subjected to smoothing-transmission.
5. The information processing apparatus according to claim 1 , further comprising:
a reception means configured to receive an image quality request that is a request in relation to image quality of the data and a transmission quality request that is a request in relation to transmission quality in the data transmission,
wherein the adjustment means adjusts the reception buffer time based on the image quality request and the transmission quality request received by the reception means.
6. The information processing apparatus according to claim 5 ,
wherein the adjustment means sets a provisional reception buffer time based on the image quality request and the transmission quality request received by the reception means, and adjusts the reception buffer time based on the provisional reception buffer time.
