  • Patent number: 8259233
    Abstract: A system for processing a television (TV) picture-out-picture (POP) includes a line buffer, a first multiplexer, an image processing engine, a scaling engine and a timing generator. The line buffer receives partial pixels of a first picture and partial pixels of a second picture. The first multiplexer selects the partial pixels of the first and second picture as an output. The image processing engine performs an image processing on the partial pixels output by the first multiplexer to thereby produce processed pixels. The scaling engine performs a scaling operation on the processed pixels to thereby produce scaled pixels. The timing generator produces a timing signal for the image processing engine and the scaling engine and produces enable signals respectively for the first picture and the second picture. The image processing engine and the scaling engine process the partial pixels of the first or second picture in multiplexing.

  • Publication number: 20050025159
    Abstract: Four methods for transmitting data in base stations of radio access network are provided. Each base station includes a plurality of logic channels, a plurality of transport channels and a media access control layer. The logic channels are configured to receive data and transmit it to the media access control layer. The media access control layer distributes the data by means of the methods of the preset invention and then the data is able to transmit through the transport channels.
