Publication number: 20080271093Abstract: A recording/reproduction device is provided wherein service content having interactivity can be restored even when recorded. In recording mode, a transport stream from a receiving device 34 is received and a conversion device 36 converts this to a packet-multiplexed stream in a condition suitable for recording, which is then output as a converted stream. The conversion device 36 selects packets relating to a desired service from the transport stream and, of these packets, selects only packets needed for reproduction and uses these to generate a converted stream. A recording device 38 records this converted stream on a recording medium 44. In reproduction mode, the converted stream from recording medium 44 is read by means of a reading device 42 and supplied to a restoration device 40. Restoration device 40, in accordance with the content of this converted stream, restores and outputs a service content signal (for example a composite signal such as NTSC).Type: ApplicationFiled: July 2, 2008Publication date: October 30, 2008Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Shinji Nabeshima, Naoya Takao, Kazuo Okamura

Patent number: 7340687Abstract: The present invention provides a device and a method for displaying appropriately on the display area for each processing unit such as an application according to the applied equipment. The CPU 12 processes display area acquisition requests from a plurality of processing units R1-Rn according to a display management program. The display management program decides whether use of the display area is allowed to each processing unit, considering the relationship of the plurality of display areas requested from each processing unit R1-Rn. Each processing unit R1-Rn executes display processing for the display area for which use is allowed. In this way, whether use is allowed is notified from the display management program to each processing unit R1-Rn after each processing unit R1-Rn sends the display area acquisition request. As a consequence, display in a plurality of areas by each processing unit R1-Rn can be controlled appropriately.Type: GrantFiled: January 2, 2004Date of Patent: March 4, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takuya Sekiguchi, Taketo Yoshii, Kouichi Yasutake, Kazuo Okamura
