  • Patent number: 10531136
    Abstract: A device, method, and program for data stream reproduction are disclosed. In one example, a transmission device includes a multiplexer that generates a data stream by multiplexing a data packet and a control information packet separately from each other, the data packet being a packet including reproduction data as the current data to be reproduced, the control information packet being a packet including control information to be used in reproducing the reproduction data. The multiplexer multiplexes a first packet in a position behind the position located a predetermined first number of packets before a second packet among multiplexing-enabled positions in which the control information packet can be multiplexed in the data stream, the first packet being the control information packet including the control information corresponding to a predetermined processing unit of the reproduction data, the second packet being the data packet including the processing unit.

  • Patent number: 10433004
    Abstract: The present disclosure relates to a reception apparatus, a reception method, and a program for generating a time stamp with a simple circuit structure that is realized at low cost. In one example, a reception apparatus includes a reception unit, an obtaining unit, a time stamp increment value specifying unit, a time stamp calculating unit and a time stamp adding unit. The reception unit receives a data stream formed of a series of packets. The obtaining unit obtains a transmission parameter from the received data stream. The time stamp increment value specifying unit specifies a time stamp increment value corresponding to the obtained transmission parameter. The time stamp calculating unit updates the time stamp by adding the specified time stamp increment value to a previous time stamp, and the time stamp adding unit adds the updated time stamp to the packets configuring the data stream.

  • Patent number: 10218626
    Abstract: The present disclosure relates to a data processing device, a receiving device, a data processing method, and a program that can suppress the occurrence of reproduction faults caused by a reduction in bit rate. An input packet classifying unit classifies an input packet as a high priority packet or a low priority packet according to priority order based on data included in packets configuring a stream. An output packet selecting unit preferentially selects and outputs a packet of high priority order from among packets that have been classified by the input packet classifying unit and being retained in a high priority packet FIFO or a low priority packet FIFO. The present technology is applied to, for example, a receiving device that can receive a plurality of streams.

  • Publication number: 20180352290
    Abstract: Communication reception that enables reception of a packet which may not contain an error without invalidating the same is disclosed. In one example, an information analyzing unit analyzes a data string and frame/slot information, and supplies TMCC information, slot header information, and data length information to a packet length indicating unit and a packet dividing unit. The packet length indicating unit defines the packet length in advance, and indicates the defined packet length to the packet dividing unit. The packet dividing unit performs packet division on the basis of the packet length obtained from the TMCC information, the slot header information, the data length information and the like from the information analyzing unit, and the packet length defined by the packet length indicating unit.

  • Patent number: 10129501
    Abstract: The present disclosure relates to an image processing device, an image processing method, and a program capable of increasing the utility of processing for reducing discontinuity in display of image frames acquired through imaging at different imaging rates. From image frames including normally imaged frames imaged at a normal imaging rate, and high-rate imaged frames imaged at a rate higher than the normal imaging rate, determination is made on image frames imaged at at least one of the imaging rates to be image frames for which a displaying rate is to be changed. The displaying rate of the image frames determined to be the image frames for which the displaying rate is to be changed is adjusted within a predetermined range from a timing when the imaging rate is switched. The present technology is applicable to an image processing device configured to perform image processing on image frames, for example.

  • Publication number: 20180248653
    Abstract: The present disclosure relates to a receiving apparatus and a method therefor which are capable of decreasing a processing load and efficiently improving reproduction quality. A packet accumulating unit stores packets and packet type, and another packet information. A statistics information accumulating unit accumulates statistics information (e.g., an error ratio, performance (processing condition) of the receiving apparatus, a condition of a stream, and a condition of a buffer). A packet-correcting-method selecting unit selects a packet correcting method from a packet correction table generated in accordance with the packet information and packet identification/statistics information from the statistics information accumulating unit, and supplies a packet to be corrected to a packet correcting unit in a case where the packet in process is determined to be a target of correction. For example, the present disclosure can be applied to a communication system that transmits and receives data.
