  • Publication number: 20230215783
    Abstract: A semiconductor package comprises a lead frame, a chip, and a molding encapsulation. The lead frame comprises one or more die paddles comprising a first die paddle. The first die paddle comprises one or more through holes, one or more protrusions with grooves on top surfaces of the one or more protrusions, or one or more squeezed extensions. Each of the one or more through holes is filled with a respective portion of the molding encapsulation. Each of the one or more through holes may be of a rectangular shape, a rectangular shape with four filleted corners, a circular shape, or an oval shape. Each of the grooves is filled with a respective portion of the molding encapsulation. A respective side wall of each of the one or more squeezed extensions is of a swallowtail shape. The swallowtail shape directly contacts the molding encapsulation.

  • Publication number: 20150147052
    Abstract: A video information processing method and device. The video information processing method includes receiving, by a video information processing apparatus, a compressed code stream transmitted by a player, and transmitting the compressed code stream to a decoder; performing, by the decoder, decoding, and transmitting a video frame obtained by means of the decoding to the video information processing apparatus; transmitting, by the video information processing apparatus, the video frame to a postprocessing unit; and performing, by the postprocessing unit, postprocessing, and providing the postprocessed video frame to the player. In technical solutions of the present invention, the postprocessing on the video frame is implemented without greatly modifying a media processing system, thereby reducing a price for implementing video postprocessing, such as a cost and time.

  • Publication number: 20100124276
    Abstract: A method and apparatus for detecting a video field sequence and a video processing system are provided. The method includes: calculating a difference D1 between a top field Tn of a current frame and a bottom field Bn-1 of a previous frame and a difference D2 between a bottom field Bn of the current frame and a top field Tn-1 of the previous frame; and determining a displaying sequence of the top field and bottom field of the current frame by comparing D1 and D2.
