US11620972B2 System and method for association of a song, music, or other media content with a user's video content
In accordance with an embodiment, described herein is a system and method for association of a song, music, or other media content with a user's video content. The system enables a user to associate a song, music, or other media content that is associated with an audio clip and a song metadata of a media content, with a video they are about to create, or have created, to create a video moment. A recipient of the video moment can hear the audio clip in combination with the video content, and also view the song metadata overlay, to determine the name of the song and artist that was used in the video, or optionally access the song at a media server, for further listening by the recipient.
US11620970B1 Mouthpiece for single-reed wind instruments
A mouthpiece for a single reed wind instrument including a body having a beak and either a tenon or a shank, the body having a facing having a window, the facing supporting a reed secured to the body using a ligature, the gap between the surface of the facing at the tip and the reed forming an opening at the tip of the beak; protrusions extending laterally on either side of the window adjacent to the tip, a first surface of each protrusion being flush with the surface of the facing and a second surface of each protrusion being flush being flush with the surface of the beak on the opposite side as the facing, the first and second surface of each protrusion coming together as each member extends laterally from the body, the shape of each member configured to create a substantially lenticular cross section in the area where a player's lips are applied to the tip of the beak.
US11620968B2 Apparatus and method for displaying images unto LED panels
The present teaching relates to method, system, medium, and implementations for LED display. A first signal is received that signals a timing for a next data transfer. In response to the first signal, a bit-based image block stored in a memory is transferred, via a bus connected thereto, to one of a pair of alternate buffers pointed to by a write buffer pointer, which is subsequently toggled to point to another of the pair of alternate buffers. A second signal is received that signals a timing for refreshing the LED display. In response to the second signal, the bit-based image block is retrieved from the one of the pair of alternate buffers pointed to by a read buffer pointer, which is then toggled to point to the other of the pair of alternate buffers. The lights of the LED display are then refreshed in accordance with control signals generated based on the bit-based image block.
US11620967B2 Image processing device and method
An image processing device having a processor coupled to a memory. The processor is programmed to process two or more media formats stored in the memory, each media format is made up of one or more digital image layers that includes non-transparent pixels and may include transparent pixels. The processor is programmed to: set the non-transparent pixels in each of the digital image layer of the two or more media formats to a contrast state, set pixels stored in an off-screen data buffer of the memory to pixels corresponding to a predetermined color scheme, apply an image function to each media format that is drawn to the off-screen data buffer so as to allow the plurality of overlapping media formats to be displayed on the display screen as see through.
US11620965B2 Video display method, video display system, electronic device, and storage medium
A video display method includes: acquiring at least one frame image corresponding to a current display time point in at least one source video; reading a stage configuration file, obtaining a stage modeling parameter of the stage space at the current display time point and a corresponding relationship between the at least one frame image and the stage space according to a specific stage related parameter in the stage configuration file; according to the stage modeling parameter and the corresponding relationship, processing the at least one frame image to obtain divided regions corresponding to all display screens included in the at least one stage plane; determining display contents corresponding to the divided regions, and copying the display contents to at least one target memory; and outputting a content in the at least one target memory to the at least one stage plane for display.
