  • Patent number: 8467665
    Abstract: 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.

  • Publication number: 20130076742
    Abstract: A reproducing device capable of superimposing a reproducing device image onto a stereoscopic image which can be viewed stereoscopically to generate and output a stereoscopic image signal. The reproducing device includes: an acquisition unit operable to obtain information about device image depth, the device image depth being stereoscopic vision depth that a device connected to the reproducing device and capable of superimposing a device image onto the stereoscopic image gives to the device image when the device superimposes the device image onto the stereoscopic image; a superimposing unit operable to give reproducing device image depth to the reproducing device image based on the information about device image depth obtained by the acquisition unit and superimpose the reproducing device image onto the stereoscopic image to generate the stereoscopic image signal; and a transmission unit operable to transmit the stereoscopic image signal to the device.

  • Patent number: 8368811
    Abstract: 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.

  • Patent number: 8351756
    Abstract: 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.

  • Patent number: 8311130
    Abstract: 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.
