Patent number: 8307123Abstract: The present invention provided a content delivery system that can deliver content by way of the Internet. In the system, a browser requests a content server to deliver a startup file. The content server transmits the startup file to the browser. The startup file describes that the content is to be delivered by streaming or that it is to be delivered by downloaded files. A content reproducing section determines if the content is that to be delivered by streaming or that to be delivered by downloaded files according to the description of the startup file it receives from the browser. A television receiving set may be used as content processing apparatus for receiving the delivery of the content from a content delivery apparatus of such a system.Type: GrantFiled: May 7, 2010Date of Patent: November 6, 2012Assignees: Sony Corporation, Panasonic CorporationInventors: Yoshiharu Dewa, Naohisa Kitazato, Tatsuya Shimoji, Yoshinori Matsui

Patent number: 7555000Abstract: The present invention relate to a digital broadcast system, and it is an object of the invention to record contents quickly in a broadcast system which implements interactivity by transmitting a set of data repeatedly, wherein a digital broadcast receiver separates a table corresponding to video images from streams in an arbitrary order and repeats the processing of memorizing the video image data to be identified in the order of obtaining the same by means of the table corresponding to the video images until all of the set of video images have been memorized. This allows for performing, in a short time, storage process of video image data broadcast for the purpose of efficient reproduction by a receiver having no storage function. Additionally, the data is available to viewers at any time after the completion of storage thereof.Type: GrantFiled: July 27, 2005Date of Patent: June 30, 2009Assignee: Panasonic CorporationInventors: Tatsuya Shimoji, Masahiro Oashi, Hiroyuki Waki, Junichi Hirai

Patent number: 7437750Abstract: An object is to perform retrial processing according to the allowable volume on communication lines made available at response information receiving equipment. A broadcast unit 140, when broadcasting video and audio, includes retrial information in that broadcast, according to the allowable volume on the communication lines between the television receivers and the response information receiving equipment 150. Television receivers effect display based on the received digital data. Response information input by users is sent to the response information receiving equipment 150. The television receivers make retrial transmissions based on the received retrial information when communications could not be established with the response information receiving equipment 150.Type: GrantFiled: April 10, 2000Date of Patent: October 14, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yasuyuki Sonoda, Tatsuya Shimoji, Kazuo Okamura

Publication number: 20060107270Abstract: The present invention provides a system capable of individually controlling each of receiving devices while making full use of the advantages of broadcasting. Simultaneous transmission is carried out from a broadcasting device 2 to a plurality of receiving devices 6 via a broadcasting path. Further, the broadcasting device 2 sends operation control data to the receiving device 6 through a communication path. The receiving device 6 changes its operation in accordance with the operation control data when received broadcasting is decoded. In this way, each of the receiver devices 6 can be controlled individually using the operation control data while making full use of the advantages of broadcasting.Type: ApplicationFiled: January 4, 2006Publication date: May 18, 2006Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Keisei Yamamuro, Tatsuya Shimoji, Yuki Kusumi, Yasushi Nishimura, Kazuo Okamura, Yasunori Tanaka
