Problems solved by technology
Therefore, there is a problem that it is difficult for the user to judge whether the reason why the projector cannot reproduce data is due to a defect in the projector itself, or whether the problem is that the format of the data is not suitable.
[0007] Here, as described in Patent Document 1, the computer can also convert the data into a format that can be reproduced by the projector and transmit it. The processing load on the computer side is heavy and the processing takes a long time

Embodiment Construction
[0021] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
[0022] figure 1 It is a schematic configuration diagram of the image supply system 1 . The image supply system 1 is composed of a computer 3 which is an image supply device and a projector 5 which is an image display device. The computer 3 and the projector 5 are connected by a network cable 6 so that data can be transmitted and received. The network cable 6 may be a LAN (Local Area Network) cable, or a USB (Universal Serial Bus) cable or the like.
[0023] The computer 3 has a control unit 31 , a storage unit 32 , an input unit 34 , an output unit 35 , and a network communication unit 36 . The control part 31 is a central processing unit (CPU: Central Processing Unit) or a microprocessor, etc., and performs control of each part of the computer 3, and the process mentioned later. The storage unit 32 is, for example, a storage device such as a n...

The present invention relates to an image supply apparatus, an image supply system and an image supply method which can reliably provide reproduced data of an image display apparatus and output warning under the condition that the image display apparatus does not reproduce the data. A specification information receiving unit of a control section of a computer receives specification information transmitted from a projector through a network image section. A reproduction judging unit compares the specification information with attribute information of a dynamic image of which the users request reproduction to determine whether or not the dynamic image file can reproduce in the projector. Under the condition of determining that the dynamic image file can not reproduce in the projector, a warning outputting unit outputs the warning to the users through an output portion. A data transmitting unit transmits the data of the dynamic image file to the projector when the dynamic image file can reproduce by the projector.
Description
technical field [0001] The present invention relates to a data supply technology for supplying data to an image display device for reproducing moving images and the like. Background technique [0002] In recent years, content utilization such as downloading content such as moving images and music from a server computer and reproducing it on a reproduction terminal such as a portable terminal or a computer has been increasing. At this time, if the playback terminal does not correspond to the file format or bit rate of the content, the content cannot be played back. [0003] Patent Document 1 discloses a technology in which a reproduction terminal transmits to a computer the file format and bit rate of content that can be reproduced by the reproduction terminal itself, and if the computer determines that the content to be transmitted to the reproduction terminal is in the transmitted file format and bit rate cannot be reproduced, the content is converted into a file format an...
