Document Type and Number:
Japanese Patent JP4539018
Kind Code:
B2
Abstract:
This invention relates to a transmission controlling apparatus, a transmission controlling method, a recording medium, and a program for instantaneously transmitting data while averting a so-called slow start. Video data acquired by a picture acquisition unit 21 is input to an initial rate determination unit 24 and a picture encoding unit 22 as outgoing data. An acceptable picture quality determination unit in the initial rate determination unit 24 determines a minimum acceptable picture quality acceptable to a user who views the video data sent from a transmission unit 11. A transmission rate determination unit in the initial rate determination unit 24 determines as an initial transmission rate the transmission rate that meets criteria for the minimum acceptable picture quality supplied from the acceptable picture quality determination unit, and forwards the determined rate to a rate control unit 25. In turn, the rate control unit 25 controls the transmission rate for a transmission unit 23 so that the unit 23 starts to send video data at the initial transmission rate supplied from the transmission rate determination unit 44. This invention applies illustratively to transmitting apparatuses for transmitting predetermined data.
