Benefits of technology

The present in this patented technology allows for faster or more efficient generation of movies without requiring complicated calculations that would otherwise have been necessary when converting them onto another format like bitmap images. This reduces the time it takes to convert large amounts of video content on different devices.

Problems solved by technology

The technical problem addressed in this patents relates to efficient communication over mobile networks with varying speeds due to changes caused during movement. Existing solutions require downloading entire videos without starting playback have limitations like delayed playing back after initial request. Additionally, existing techniques only work well within certain types of video sequences, limit their effectiveness in delivering movies quickly across different devices connected wirelessly.

first embodiment

[0082]FIG. 3 is a diagram showing the configuration of a moving image data distribution system that uses moving image data conversion in a first embodiment of the present invention. As shown in FIG. 3, the whole system comprises a moving image data distribution device 10, a moving image data conversion device 20, a moving image data reproduction device 30, and a transmission line 40 for transmitting moving image data. The moving image data conversion device 20, connected to the transmission line 40 where an IP network is built, distributes moving image data via IP communication. The moving image data reproduction device 30 is a client terminal connected to the IP network. The moving image data conversion device 20 captures accumulated data or streaming data from the moving image data distribution device 10, converts the data, and supplies the converted data to the moving image data reproduction device 30 as streaming data.

[0083] The moving image data distribution device 10 comprises a

second embodiment

[0102]FIG. 6 is a diagram showing the configuration of a moving image data distribution system that uses moving image data conversion in a second embodiment of the present invention. As shown in FIG. 6, the whole system comprises a moving image data distribution device 10, a moving image data conversion device 20b, a moving image data reproduction device 30, and a transmission line 40 for transmitting moving image data. The moving image data distribution device 10, the moving image data reproduction device 30, and the transmission line 40 are the same as those described in the first embodiment and, therefore, their description is omitted.

[0103] The moving image data conversion device 20b captures accumulated data or streaming data from the moving image data distribution device 10, transcodes to covert the captured data, and supplies the transcoded data to the moving image data reproduction device 30 as streaming data. The moving image data conversion device 20b comprises a connection

third embodiment

[0112]FIG. 7 is a diagram showing the configuration of a moving image data distribution system that uses moving image data conversion in a third embodiment of the present invention. As shown in FIG. 7, the whole system comprises a moving image data distribution device 10, a moving image data conversion device 20c, a moving image data reproduction device 30, and a transmission line 40 for transmitting moving image data. The moving image data distribution device 10, the moving image data reproduction device 30, and the transmission line 40 are the same as those described in the first embodiment and, therefore, their description is omitted.

[0113] The moving image data conversion device 20c captures and converts accumulated data or streaming data from the moving image data distribution device 10 and supplies the converted data to the moving image data reproduction device 30 as streaming data. The moving image data conversion device 20c comprises a connection call processing unit 21c, a mo
