  • Patent number: 10136127
    Abstract: In prior art documents, no consideration is given as to how to more faithfully preserve image (here and subsequently also termed “video”) data of larger size during transmission. Provided is an image transmission device for transmission of image data, characterized by having a compression processor for compressing image data, and an output section for outputting compressed data having been compressed by the compression processor, the output section outputting the compressed data separately during a first interval and a second interval different from the first interval.

  • Patent number: 10136221
    Abstract: Practical speaker connection is identified using a device having a sound channel of a 5.1 channel or 7.1 channel, and a device is provided that can easily reproduce the optimum multiple channels. Actual speaker arrangement can be identified by, for example, measuring the impedance of a terminal at the side of an audio amplifier. If incorrect connection is found, a warning is issued. This information is transmitted to a signal source with an EDID and a signal with the optimum a number of sound channel is sent. The EDID is also used for the connection with a display unit and the speaker connection with which the display unit is provided uniquely. For example, a sound through the 7.1 channel is easily reproduced using the speaker of the display unit in the channel of the front speaker.

  • Publication number: 20180146234
    Abstract: The present invention is intended to permit both real-time display of a picture represented by a non-compressed video signal on a television and display of a picture represented by a compressed video signal at any desired time by simultaneously transmitting the compressed video signal and non-compressed video signal via one interface. An STB packetizes a compressed video signal, and multiplexes the compressed video signal and a blanking signal combined with a non-compressed video signal. Thus, both the video signals are transmitted simultaneously. A picture represented by the non-compressed video signal is displayed on a television in real time. The compressed video signal is stored in a storage medium incorporated in the television, read at any user's desired time, and decoded so that a picture represented by the compressed video signal can be viewed at the user's desired time.

  • Patent number: 9848185
    Abstract: A video display system includes a source device for reproducing and outputting contents; and a display device for displaying contents which is output from the source device. Upon receiving a message for requesting display of a 3D video from the source device in a state of unreadiness to display the 3D video, the display device transmits a message for stopping reproduction of 3D contents to the source device. Upon receiving the message for stopping reproduction of 3D contents, the source device stops reproduction of the 3D contents. Upon completing preparations for displaying the 3D video, the display device transmits a message for reproducing the 3D contents to the source device. Upon receiving the message for reproducing the 3D contents, the source device reproduces and outputs the 3D contents.

  • Publication number: 20170251170
    Abstract: A video display with high image quality is achieved even when a frame cycle varies for each frame. A video display system includes a video source device 11 which outputs a video signal and a display device 12 which displays a video based on a video signal output from the video source device 11. The video source device 11 includes a drawing time prediction unit 104 and a transmitting unit 102. The drawing time prediction unit 104 calculates frame interval information indicating an interval from when a video signal of a first frame is output to when a video signal of a second frame to be a next frame of the first frame is output. The transmitting unit 102 transmits the frame interval information calculated by the drawing time prediction unit 104 to the display device 12.
