Portable terminal, streaming communication system, streaming communication method, and streaming communication program

Abstract

A portable terminal, a streaming communication system, a streaming communication method, and a streaming communication program can prevent the billing of packet charges when, during streaming communication, proper line speed cannot be secured and normal reproduction is not possible. A configuration is adopted such that, when executing streaming communication, comparison / determination unit 18 compares / determines a communication bit rate value that is acquired by means of communication bit rate value acquisition unit 16 and an effective bit rate value that is calculated by effective bit rate value calculation unit 17. Streaming communication is thus executed when the effective bit rate value is the greater value, and streaming communication is not executed when the communication bit rate value is the greater value.

Description

Technical field [0001] The present invention relates to a portable terminal, a streaming communication system, a streaming communication method, and a streaming communication program, and more specifically, to a portable terminal that determines whether to perform streaming communication, a streaming communication system, a streaming communication method, and a streaming communication program. Background technique [0002] In recent years, moving picture data distribution or voice data distribution is performed using RTP (Real Time Transport Protocol) streaming in portable terminals such as portable phones. [0003] Streaming is data reproduction in which when moving picture data or voice data is distributed from a network such as the Internet, the user reproduces the data while downloading the data file instead of reproducing the data after the data file is downloaded. Motion picture data and voice data generally include a large amount of data, so streaming is particularly usefu...

AI Technical Summary

Problems solved by technology

Failure to guarantee an appropriate line speed not only prevents the normal reproduction of the target content, but also may require the user to pay for packet data communication that cannot be reproduced, which puts the user at a very disadvantageous position

[0009] Since it cannot be determined from the appearance whether an appropriate line speed for realizing streaming communication has been secured, the user cannot judge whether streaming communication is possible, so that the user tends to have a negative impression of streaming communication

[0010] The prior art described above assumes that communication is possible and therefore does not take these issues into account, thereby providing no means for the user to determine whether streaming communication is possible
