Problems solved by technology

[0004] Data broadcast using network connection can provide various information to user devices beyond the limitation of transmission based on broadcast waves. On the other hand, user devices may be damaged Display performance cannot cope with a variety of information
When the user device chooses to receive content beyond its own display capability, the received content cannot be reproduced, which may cause obstacles to normal functions
Therefore, there is a need to limit the information sent to user devices

Embodiment Construction

[0029] Next, specific embodiments of the data broadcasting system, data broadcasting server and data broadcasting program disclosed in the present invention will be described.

[0030] figure 1 It is a diagram showing a specific embodiment of a data broadcasting system.

[0031] figure 1The shown data broadcasting system S has: a broadcasting station 1 that transmits one-segment broadcasting data using terrestrial waves, user devices 2, 3, 4 that receive broadcasts from the broadcasting station, and two-way communication with the user devices 2, 3, 4 and A data broadcast server 6 (hereinafter simply referred to as server 6) that provides data broadcast information. User devices 2 , 3 , 4 and server 6 are connected via network 7 . The network 7 is, for example, the Internet.

[0032] The broadcasting station 1 wirelessly transmits One-Seg Broadcasting data using broadcast waves (terrestrial waves). User apparatuses 2, 3, 4 receive data transmitted from broadcasting station...

Abstract

A data broadcast system includes, to avoid reception of contents exceeding display performance at a user device, the user device including a network connection part for requesting transmission of link information together with its own model information, and a data broadcast server including a contents performance determination part for receiving the model information and acquiring the contents display performance and a secondary link information transmission part for transmitting, to the user device, link information and information added thereto which indicates whether or not the contents indicated by the link information are the contents requesting the contents display performance exceeding the performance of the user device.

Description

technical field [0001] The present invention relates to a data broadcasting system, a data broadcasting server and a data broadcasting program. Background technique [0002] In terrestrial digital television broadcasting in which digitized video and audio signals are transmitted using terrestrial waves, the frequency band of the broadcast signal is divided into 13 bands and used. One-segment broadcasting, which is mainly for mobile objects, is implemented using one of the bands. The reception function of one-segment broadcasting has been introduced not only into dedicated television receivers, but also into information devices such as personal computers and mobile phones. [0003] In one-segment broadcasting, data broadcasting that provides information via networks such as the Internet is implemented as an additional service in addition to images and audio of normal television programs provided from broadcasting stations using terrestrial waves. In data broadcasting, link ...
