Patent number: 8467665Abstract: A playback device judges whether a connected display device is equipped to display only interlaced video or both interlaced and progressive video. If equipped to display both interlaced and progressive video, a mode setting unit 15 sets an operation mode of the playback device to an image quality mode for interlaced signal output or a continuity mode for progressive signal output, according to a user selection received via a GUI. If continuity mode is set, the playback device decodes the video stream and performs progressive signal output.Type: GrantFiled: September 27, 2010Date of Patent: June 18, 2013Assignee: Panasonic CorporationInventor: Tetsuya Itani

Patent number: 8368811Abstract: According to the present invention, the sound quality of an apparatus having HDMI outputs exclusive for both of an audio signal and a video signal can be further improved. According to the present invention, even when the calculated value of CTS obtained using a first video clock signal Vc1 generated by a decoder 204 is other than an integer, a value of a second video clock signal Vc2 and an N value are set such that the calculated value of CTS obtained using the second video clock signal Vc2 is an integer. By using the value of second video clock signal Vc2 and the N value set in this manner, an audio reproducing apparatus 103 can generate an audio clock signal Ac having reduced jitter.Type: GrantFiled: January 25, 2011Date of Patent: February 5, 2013Assignee: Panasonic CorporationInventor: Tetsuya Itani

Patent number: 8351756Abstract: An up-converter (7) performs up-conversion on frame images in a video signal. A pseudo-noise generation circuit (9) generates a pseudo-noise signal, and an adder (10) composites the pseudo-noise signal with the up-converted video signal. As a result, noise having the same resolution as the up-converted frame images (1920 vertical pixels by 1080 horizontal lines) is distributed in the composited frame images, and each piece of noise has a characteristic approximating a characteristic (crest value, amount, or frequency) of noise included in the pre-conversion video signal.Type: GrantFiled: November 29, 2006Date of Patent: January 8, 2013Assignee: Panasonic CorporationInventor: Tetsuya Itani

Patent number: 8311130Abstract: A video decoder is connected with a block distortion detector for specifying the boundary of blocks where block boundary occurs, using decoded image data and information of motion vectors, which are supplied from the video decoder; and a block distortion remover for subjecting pixels in the vicinity of the block boundary of the decoded image to filtering on the basis of the result of detection from the block distortion detector, thereby removing the block distortion. Therefore, block distortion is accurately detected when a compressed and coded image is decoded, and the detected block distortion is removed while minimizing the blurriness of the image.Type: GrantFiled: May 3, 2011Date of Patent: November 13, 2012Assignee: Panasonic CorporationInventors: Satoshi Kondo, Tetsuya Itani
