The broadcast reception device includes: an IP communication unit establishing a pairing session with the companion device; a broadcast communication unit receiving first Non-Real Time (NRT) data signaling information signaling NRT data that is a content of an NRT service, on the basis of the broadcast service; and a control unit transmitting second NRT signaling data for the companion device to the companion device on the basis of the first NRT data signaling information. | 2017-06-22 |
20170180764 | TIME LAPSE RECORDING VIDEO SYSTEMS - A system for time lapse video recording includes an image processing device configured to receive a compressed video that is encoded using a video compression module operative to encode video from a video camera using a video compression standard, wherein the image processing device is operative to control a time lapse rate to pick and store a plurality of image frames from the series of compressed image frames at the time lapse rate to create a time lapse video, wherein the image processing device is configured to cause the video compression module to modify a GOP length to achieve a predetermined time lapse video quality. | 2017-06-22 |
20170180765 | SYSTEM AND METHOD FOR ROUTING MEDIA - A video streaming system comprises a plurality of servers, each of the plurality of servers including one or more processors and a memory. One or more of the plurality of servers receive video content from a video content owner and store the received video content in a plurality of geographically separated resources of a content distribution network. The one or more of the plurality of servers receive from a client device via a packet-based telecommunication network signaling to have the stored video content streamed to the client device from one or more of the resources of the content distribution network. In response to the received signaling, the one or more of the plurality of servers transmit to the client device, via the packet-based telecommunication network and in one or more files, each of the one or more files being in a format compatible with a media player on the client device, (i) an identification of one or more of the resources of the content distribution network available to facilitate streaming of one or more segments of the stored video content to the client device, the identification being dependent at least in part on a relationship between a geographic location of the client device and geographic locations of the resources of the content distribution network, and (ii) an identification of an advertising server, the identification of the advertising server being dependent at least in part on a relationship between the geographic location of the client device and a geographic location of the advertising server, wherein the one or more files, when processed by the client device cause the client device to communicate with the identified one or more resources of the content distribution network and the advertising server to cause the one or more segments of the stored video to be streamed to the client device by the identified one or more resources of the content distribution network and cause one or more advertisements to be streamed from the advertising server to the client device. | 2017-06-22 |
20170180766 | TRANSMITTING DEVICE, RECEIVING DEVICE, TRANSMITTING METHOD AND RECEIVING METHOD - A transmitting device includes: a generator that generates an encoded stream by using rate control satisfying a determined definition of a receiving buffer model; and a transmitter that sequentially transmits a transmitting packet, and the receiving buffer model includes a first buffer that converts a packet into a first packet where the packet includes a packet header of a variable length, and the first packet includes a packet header of a fixed length of a decompressed header, a second buffer that converts the first packet into a second packet including a payload of a variable length, a third buffer that converts the second packet into a Network Abstraction Layer (NAL) unit, and a fourth buffer that outputs an access unit generated from a plurality of sequentially accumulated NAL units to a decoder at a timing of a decoding time corresponding to the access unit. | 2017-06-22 |
20170180767 | METHOD AND APPARATUS FOR TRANSCEIVING BROADCAST SIGNAL - The present invention relates to an apparatus and a method for transceiving a broadcast signal including a subtitling service. One embodiment of the present invention provides a method for transmitting a broadcast signal, comprising the steps of: encoding video data to generate a video stream; generating a broadcast signal including the generated video stream and a subtitle stream; and transmitting the generated broadcast signal. According to the embodiment of the present invention, a transmission stream which provides a digital broadcast subtitling service using an XML subtitle can be transmitted. | 2017-06-22 |
