Plural Input Channels Of Different Rates To A Single Common Rate Output Channel Patents (Class 370/538)
  • Patent number: 10334327
    Abstract: A method transcodes a media program to produce a constant video quality transcoded version of the media program. The constant video quality transcoded version is transcoded by a transcoder operating in a first mode that targets video quality. A portion of the constant video quality transcoded version that fails to satisfy a constraint is determined. The method sets a transcoding parameter based on the portion failing to satisfy the constraint. A portion of the media program corresponding to the portion of the constant video quality transcoded version is transcoded according to the transcoding parameter to produce a constant bit rate version of the portion. The constant bit rate version is transcoded by the transcoder operating in a second mode that targets a bit rate. The method then substitutes the constant bit rate version for the portion of constant video quality transcoded version in generating a transcoded media program.

  • Patent number: 8711889
    Abstract: A method for adapting the rates of a certain number of asynchronous HDLC channels (15) to a single clock domain suited for interfacing with an HDLC processor (13) through a synchronous pseudo-TDM interface (14) in which the HDLC channels are multiplexed in time and vice versa in the opposite direction. In one direction the algorithm is based on the writing of the HDLC channels in a dedicated buffer (17) and in reading these buffers with a common synchronous clock just above the expected maximum HDLC rate. The under-run condition is avoided by inserting neutral information between the end byte and the start byte of the HDLC packets when this is suggested by the buffer fill monitoring function. A simple function to locate the first and last bytes of each HDLC packet read by the buffer is hence used in combination with the buffer fill monitoring function.

  • Patent number: 8364495
    Abstract: An encoding device capable of realizing a scalable CODEC of a high performance. In this encoding device, an LPC analyzing unit (551) analyzes an input voice (301) efficiently with a synthesized LPC parameter obtained from a core decoder (305), to acquire an encoded LPC coefficient. An adaptive code note (552) is stored with its sound source codes, as acquired from the core decoder (305). The adaptive code note (552) and a stochastic code note (553) send sound source samples to a gain adjusting unit (554). This gain adjusting unit (554) multiplies the individual sound source samples by an amplification based on the gain parameters acquired from the core decoder (305), and then adds the products to acquire sound source vectors. These vectors are sent to an LPC synthesizing unit (555). This LPC synthesizing unit (555) filters the sound source vectors acquired at the gain adjusting unit (554), with the LPC parameter, to acquire a synthetic signal.

  • Patent number: 8351428
    Abstract: A digital broadcast transmitting/receiving system and a method for processing data are disclosed. The method for processing data may enhance the receiving performance of the receiving system by performing additional coding and multiplexing processes on the traffic information data and transmitting the processed data. Thus, robustness is provided to the traffic information data, thereby enabling the data to respond strongly against the channel environment which is always under constant and vast change.

  • Patent number: 8340140
    Abstract: A plurality of programs are statistically multiplexed using a statistical multiplexing (stat mux) system. Rchannel, a constant total bit rate for the plurality of programs, is determined. Cl,Ff,picTYpe, a complexity for each picture in the plurality of programs, is determined. Tl,Ff,picType, a bit allocation for each picture in the plurality of programs, is determined based on Cl,Ff,picTYpe and Rchannel. The plurality of programs are encoded using a plurality of encoders, a combined encoder buffer, and Tl,Ff,picType to form a plurality of variable bit rate (VBR) compressed bit streams. The plurality of VBR compressed bit streams are multiplexed to form a single constant bit rate (CBR) bit stream.

  • Patent number: 8331402
    Abstract: A first header-attaching unit attaches to data of a low speed bit rate A, a header of the bit rate A. A second header-attaching unit attaches the header of the bit rate A to data of a high speed bit rate B. A combining unit combines outputs of the first and the second header-attaching units. A low speed scrambling unit performs a scrambling process on combined data by using a clock corresponding to the bit rate A. A high speed scrambling unit performs a scrambling process on the data of the bit rate B by using a clock corresponding to the bit rate B. During a timing corresponding to the bit rate A in the frame, a selector selects an output of the low speed scrambling unit. During a timing corresponding to the bit rate B in the frame, the selector selects an output of the high speed scrambling unit.

  • Patent number: 8302148
    Abstract: To improve transmission of digital broadcast information, there is proposed a method of transmitting digital broadcast information from a main transmitter (12) to at least one repeater (14). There is generated a composite digital broadcast signal carrying first digital broadcast information according to a first digital broadcast specification (DVB-T) and second digital broadcast information according to a second digital broadcast specification (DVB-H). The composite digital broadcast is then broadcasted such that the second digital broadcast information (DVB-H) is sent in a transmission mode used for transmission of the first digital broadcast information (DVB-T).

  • Patent number: 8275003
    Abstract: An aspect of the invention relates to a method and apparatus for multiplexing content. In one example, a first transport stream is received. The first transport stream includes a sequence of burst cycles, each of the burst cycles having a plurality of packet bursts respectively associated with a plurality of primary services. In one example, a primary service is a national service. A packet burst stream is received that is associated with a secondary service. In one example, a secondary service is a regional service. The first transport stream is multiplexed with the packet burst stream to produce a second transport stream. The second transport stream includes a deterministic relationship between the plurality of packet bursts in each of the burst cycles and packet bursts of the packet burst stream. Additional packet burst streams associated with additional secondary services may be received and multiplexed in a similar manner.

  • Patent number: 8199775
    Abstract: An output control unit outputs data of bit rate A to a first header-attaching unit and data of bit rate B to a second header-attaching unit. An instructing unit instructs the first or the second header-attaching unit to attach a header of bit rate being the least bit rate to the data of bit rate A or B. The first header-attaching unit creates a header of bit rate A, including an ID of a destination ONU of the data of bit rate A and information concerning the data length, and attaches the header of bit rate A to the data of bit rate A. The second header-attaching unit creates a header of bit rate A, including an ID of the destination ONU of the data of bit rate B and information concerning the data length, and attaches the header of bit rate A to the data of bit rate B.

  • Patent number: 8189592
    Abstract: A telephony system and method is provided that reduces delay and provides better utilization of upstream bandwidth in delivering packet telephony services to a plurality of subscriber lines via a cable modem system. An exemplary system includes a plurality of voice processing modules, a host processor, and a buffer. Each voice processing module receives digital voice signals from a separate set of subscriber lines, compresses the digital voice signals to generate a voice packet, and transfers the voice packet to the buffer. The host processor then assembles a packet by concatenating the voice packets and transmits the assembled packet for delivery over a data network. Because the plurality of voice processing modules process the voice packets in parallel, delay is reduced in the assembly and transmission of the assembled packet.
