| 20090154552 | TRANSMITTING SYSTEM AND RECEIVING SYSTEM FOR PROCESSING STREAM, AND STREAM PROCESSING METHODS THEREOF - A system for transmitting a transport stream including a robust stream is provided. The transmitting system includes an adaptor for, when receiving a first stream, making a space in the first stream to insert a second stream; a Reed-Solomon (RS) encoder for RS-encoding the input second stream; a Cyclic Redundancy Check (CRC) processor for converting the RS-encoded second stream to a stream comprising an added CRC bit sequence; and a stuffer for inserting the stream to the space in the first stream and outputting a transport stream. Hence, the robust stream can be efficiently transmitted. | 06-18-2009 |
| 20100183077 | RESPONSE TO ATSC MOBILE/HANDHELD RFP A-VSB MCAST AND, A-VSB PHYSICAL AND LINK LAYERS WITH SINGLE FREQUENCY NETWORK - A digital broadcasting transmitter including a Reed-Solomon (RS) encoder to encode signaling information, and a randomizer to randomize a stream including the signaling information encoded by the RS encoder. The signaling information is used by a receiver to demodulate and/or equalize the stream. | 07-22-2010 |
| 20100195712 | RESPONSE TO ATSC MOBILE/HANDHELD RFP A-VSB MCAST AND PHYSICAL LAYERS FOR ATSC-M/HH - The Mobile Broadcasting (A-VSB MCAST) design consists of transport and signaling opt imized for mobile and handheld services. Section 5 provides the overall A-VSB MCAST architecture. Section 6 specifies the physical and link layers. Section 7 specifies the trans port layer. And, Section 8 describes the frame slicing mechanism for burst transmission. Backwards compatibility is ensured by the careful design of the physical and link layers. | 08-05-2010 |
| 20100329382 | DIGITAL BROADCASTING TRANSMITTER AND RECEIVER, AND METHODS FOR PROCESSING STREAMS THEREOF - A digital broadcast transmitter to transmit a plurality of supplementary data streams is provided, including a multiplexer (MUX) unit which generates a transmission stream by inserting the plurality of supplementary data streams into a normal data stream so that the plurality of supplementary data streams are continuously arranged in an alternating pattern in the normal data stream, and an exciter unit which processes the transmission stream so that the plurality of supplementary data streams are distinguishably arranged in a plurality of areas forming a plurality of transmission units. | 12-30-2010 |
