An information processing device displays a video including an avatar object on a display based on video data received from a server, displays a group to which a distributing user belongs in an identifiable manner in a video view or a video distribution list including images of multiple videos, and sends a display request to display an object in one of the videos to the server.

Video distribution system, video distribution method, information processing device, and video viewing program

An information processing device displays a video view of a video including a first avatar object reflecting movement of a distributing user that distributes a video on a display, receives an input operation, displays a game view of a game including a second avatar object reflecting the input operation and the movement of the distributing user on the display, and transmitting video data for distributing a video of the game to another information processing device to a server that distributes the video.

An absolute encoder is provided with a movable member, which may be a disc, a photodetector and a processing circuit. The movable member has a plurality of tracks T arranged from higher to lower orders, each track having a bright and dark pattern. The photodetectors A1-A4 receive a light through the bright and dark patterns to output triangular detection signals A1-A4 associated with the track T. The processing circuit processes the detection signals A1-A4 to produce bit signals P1-P3 which indicate a position of the movable member. The processing circuit is provided with an input unit 1, a comparator unit 2 and a logic unit 3. The input unit 1 receives the detection signals A1-A4 for producing a plurality of triangular wave signals having the same period but different phases. The comparator unit 2 comparatively processes the triangular wave signals with each other to produce a plurality of rectangular wave signals having different phases. The logic unit 3 logically processes the rectangular wave signals with each other to output at least three bit signals P1-P3 from one track.

The optical displacement detecting device utilizes an encoder plate 2 mounted displaceably along a given first plane and having thereon a periodic slit pattern 1. A light source 4 is disposed behind the encoder plate 2 to illuminate the slit pattern 1 to form a primary fringe image 3 shifting along the first plane. A lens member 6 is utilized to project the primary fringe image 3 by a given magnification to form a secondary enlarged fringe image 5 shifting along a given second plane. A light receiving unit 8 is fixed in the secondary plane to optically detect the shifting secondary enlarged fringe image 5 through a periodic mask pattern to thereby output an electric signal 7 indicative of a displacement of the encoder plate 2.
