Abstract
Position detection means (11), time detection means (12), weather detection means (13), and transmission rate detection means (14) detect the current position, the current time, the weather, and the valid data transmission rate of a mobile reception device (3). According to the detection results, communication environment information is generated. The communication environment information is used for prediction or recognition of the communication condition between the transmission device and the mobile reception device.

12. A communication environment learning apparatus for learning a communication environment between a transmitting apparatus and a mobile receiving apparatus, in order to control a communication between the transmitting apparatus and the mobile receiving apparatus depending on the communication environment between the transmitting apparatus and the mobile receiving apparatus, in a remote playback system in which two-way communication is made between the transmitting apparatus and the mobile receiving apparatus which are wirelessly connected, in which data is transferred from the transmitting apparatus to the mobile receiving apparatus, and in which the data is reproduced on the mobile receiving device, said communication environment learning apparatus comprising:
-
a position detecting device for detecting a current position of the mobile receiving apparatus and providing position information which indicates the current position; a transmission rate detecting device for detecting an effective data transmission rate which indicates a data amount per unit time which is effectively transmitted from the transmitting apparatus to the mobile receiving apparatus and providing effective data transmission rate information which indicates the effective data transmission rate; a communication environment information generating device for generating second effective data transmission rate information by using a statistical method on the basis of the provided effective data transmission rate information and associating the position information with the generated second effective data transmission rate information, to thereby generate communication environment information which indicates (a) a position, (b) an effective data transmission rate at the position, and (c) a correspondence relationship among these; and a recording device for recording the communication environment information onto a recording medium. - View Dependent Claims (13, 14, 15, 16, 17, 18, 22, 23)
