Problems solved by technology

Therefore, in the structure of Patent Document 2, when receiving video data from the PC and then reproducing the video data on the TV, it is necessary to add many operation keys to the remote controller for the TV, which creates a problem that the user's remote controller operation is complicated.
[0021] In addition, in a conventional system composed of a PC that stores video data and a receiver that receives video data, the following problem arises: After the function of the receiver is judged on the PC included in the system, the receiver cannot be selected. The video data transmission method of the machine

Embodiment approach 1

[0052] First, Embodiment 1 will be described based on FIGS. 1 to 6 .

[0053] FIG. 1 is a diagram showing an example of a video transmission system for transmitting video data in a PC 1 and a receiver 2 connected to each other by wireless. That is, the system of this embodiment transmits the video data stored in the PC 1 to the receiver 2 via a wireless LAN, and performs video viewing through the monitor of the TV 3 connected to the receiver 2 .

[0054] In this embodiment, the PC 1 and the receiver 2 are connected to each other via a wireless LAN, but the present invention is not limited thereto, and any communication method may be used as long as the wireless communication is possible. In addition, it is not limited to wireless, and of course the PC1 and the receiver 2 may be connected by wire.

[0055] In addition, the above-mentioned system includes PC1 (video transmission device), and receiver 2 connected to TV3. Furthermore, in the PC 1 , video data is input as an anal...

Embodiment approach 2

[0157] As an example of another embodiment of the system of the present invention, 'Embodiment 2' will be described with reference to FIGS. 7 to 9 . 7 is a block diagram showing an example of another embodiment of the system of the present invention.

[0158] The system according to Embodiment 2 (second system) is a system for transmitting video data stored in PC 1 to receiver 2 via wireless LAN, and watching video through a monitor provided in TV 3 connected to receiver 2 .

[0159] In addition, like the system shown in Embodiment 1 above, the PC 1 and the receiver 2 are not limited to being connected to each other via a wireless LAN, and any communication method may be used as long as they are capable of communicating wirelessly. In addition, it is not limited to wireless, and a configuration in which the PC 1 and the receiver 2 are connected by wire may be used.

[0160] In the system shown in FIG. 1 , the system according to Embodiment 2 is different in that operation inp...

Abstract

The invention provides a video transmission device. A PC includes a processing section and a storage section. The processing section controls operation of the PC, based on connection request data for requesting a connection. The connection request data is transmitted from a receiving device. The storage section stores video to be transmitted to the receiving device. When a connection request data recognizing section of the processing section recognizes the connection request data, a connection is established between the PC and the receiving device that transmitted the connection request data, and a transmission control section transmits a video data file read by a file handling section. In the PC, the processing section includes the connection request data recognizing section and the file handling section. Therefore, even if no instruction is made from the side of the receiving device to the PC by using a remote control, it is possible to transmit video data from the PC to the receiving device, and to reproduce the video data. In addition, the PC can transmit the video data by a transmitting scheme that is in accordance with a function of the receiving device.

Description

technical field [0001] The present invention relates to a device for receiving and transmitting digitized image data by wireless. Background technique [0002] (Video viewing on TV) [0003] In the past, regarding the "act of so-called video viewing", it was generally the flexible use of a TV. In addition, the user can use the video recorder / DVD player (video recording and image reproduction device) to watch not only the video transmitted in real time, but also the video of the content requested by the user within the time required by the user. [0004] In addition, in recent years, a wireless video transmission system that connects a television and a video recording and image reproduction device wirelessly, digitizes the video signal recorded by the video recording and image reproduction device, and transmits it to a TV installed in a remote place Be practical. As an example of such a system, the wireless transmission system shown in FIG. 10 is mentioned. FIG. 10 is a b...
