20110055882 | VIDEO DELIVERY APPARATUS AND VIDEO DELIVERY METHOD - In one embodiment, a video delivery apparatus includes a determination unit, a search unit, and a delivery control unit. The determination unit determines that there is a margin in a transmission band when a state in which a packet discard rate periodically received from a receiver is below the threshold value has continued over a preset period. The search unit searches for a replacement content with a bit rate higher than a bit rate of a currently delivered video content, when it is determined that there is a margin in the transmission band as a result of determination by the determination unit. The delivery control unit sends the replacement content in place of the currently delivered video content when the replacement content has been searched by the search unit. | 03-03-2011 |
20110231514 | CONTENT DELIVERY APPARATUS, CONTENT DELIVERY METHOD, CONTENT PLAYBACK METHOD, CONTENT DELIVERY PROGRAM, CONTENT PLAYBACK PROGRAM - A content delivery apparatus according to an embodiment is a content delivery apparatus connected to a content playback apparatus via a network. The content delivery apparatus includes storage unit, management-information storage unit, and a delivery unit. The storage unit stores a content to be delivered and additional information related to the content. The management-information storage unit stores, for each content, a level index showing a hierarchical relationship between the content and the additional information. The delivery unit delivers, in response to a delivery request from the content playback apparatus, the level index of the requested content to the content playback apparatus. In addition, the delivery unit read the additional information of the requested content referring to the level index and delivers the additional information. Furthermore, the delivery units read the requested content from the storage unit and delivers the requested content to the content playback apparatus. | 09-22-2011 |
20120099656 | TRANSMITTING SYSTEM, RECEIVING DEVICE, AND A VIDEO TRANSMISSION METHOD - A stream transmitting system for transmitting a data stream, which has first layer including base data and second layer including data supplementing the base data, includes a transmitting device and a receiving device. The transmitting device includes: a transmission control unit for packetizing the data of the first layer and the data of the second layer to output a data packet of the first layer and a data packet of the second layer; first transmitting unit for transmitting the data packet of the first layer to the receiving device through first transmission path; and second transmitting unit for transmitting the data packet of the second layer to the receiving device through second transmission path. The receiving device includes: first receiving units for receiving the data packet transmitted through the first transmission paths; and a reception control unit for reconstructing a hierarchically-encoded data stream. | 04-26-2012 |
20120099831 | METHOD FOR CREATING A REPLAY SIGNAL IN A SURVEILLANCE VIDEO AND A VIDEO SYSTEM FOR CREATING A REPLAY SIGNAL IN A SURVEILLANCE VIDEO - In a transmission side, a layer adjusting unit performs an adjustment to store a scalable encoded video data in a memory, select and output a scalable data of a base quality as a real-time video, read from a memory a scalable data of an enhancement quality based on the designation of a enhancement quality and a transmission period of time, and output the scalable data of an enhancement quality together with a real-time scalable data. In the receiving side, a layer synthesizing unit synthesizes and outputs a real-time video at normal times, and lowers the real-time video to a quality of the base layer if there is an enhancement quality video of a designated period of time, thereby reading the base quality layer data corresponding to the designated video from the memory ( | 04-26-2012 |
20120257620 | PACKET DISTRIBUTION APPARATUS AND PACKET DISTRIBUTION METHOD - According to one embodiment, a packet distribution apparatus distributes packets each containing a digital content via a communication network. The packet distribution apparatus includes a generator, a packet transmitter, a detector and a swapper. The generator generates the packets for each session with a bit rate corresponding to a content to be distributed. The packet transmitter transmits the generated packets to the communication network. The detector detects a collision of transmission timings of the packets in the sessions. The swapper exchanges, upon detecting a collision of the transmission timings, a transmission order of packets associated with the collision of the transmission timings based on the bit rates. | 10-11-2012 |
20120275768 | VIDEO EDITING DEVICE, VIDEO EDITING METHOD, PROGRAM, AND MEDIUM IN WHICH THE PROGRAM IS RECORDED - A video editing device includes a storage unit, a detection unit and an composite unit. The storage unit stores a detection target, a similarity determination condition for determining a similarity of an original video content to the detection target, and a message in association with one another. The detection unit determines in accordance with the similarity determination condition whether or not the detection target is included in the original video content. The composite unit adds the message to the original video content in a case where a determination result by the detection unit indicates that the detection target is included in the original video content. | 11-01-2012 |
20130247098 | VIDEO DISTRIBUTION SYSTEM, VIDEO DISTRIBUTION APPARATUS, VIDEO DISTRIBUTION METHOD AND MEDIUM - According to one embodiment, distribution system includes live distributor and time-shifted distributor. Live distributor distributes live content by streaming. Time-shifted distributor accumulates live content distributed by streaming, and redistributes video content from reproduction position requested by viewer. Time-shifted distributor includes digest generator, menu creator and distributor. Digest generator divides video content from start time of streaming distribution to present time when streaming distribution is continuing into chapters, extracts representative frame from each of chapters, and generates digest movie including representative frame. Menu creator creates menu screen. Distributor distributes digest movie selected on presented menu screen. | 09-19-2013 |
20130339578 | SERVER AND DRIVE CONTROL DEVICE - According to one embodiment, a drive control device includes a monitor, data memory and a controller. The monitor monitors an operating state of a solid-state drive and detects whether the solid-state drive is busy. The data memory is capable of holding temporarily a write target data which should be written to the solid-state drive or a read target data which was read from the solid-state drive and should be transmitted to a requestor. The controller which writes the write target data to the data memory when the controller receives a write request and the monitor detects that the solid-state drive is busy, and which writes the write target data held in the data memory to the solid-state drive after the solid-state drive becomes not busy. | 12-19-2013 |
20140012948 | DATA TRANSFERRING APPARATUS, DATA TRANSMISSION SYSTEM AND DATA TRANSMITTING METHOD - There is provided a data transferring apparatus that transfers file data stored in a storage apparatus that manages data in a block unit, in which the first issuing unit, in response to a request from a CPU, generates and sends a reading command of metadata including first map information showing in which location first file data is stored, to the storage apparatus, the second issuing unit receives a reading command of the first file data from the CPU that has obtained the metadata, generates and sends a reading command of a block storing the first file data to the storage apparatus, the extracting unit receives block data read from the storage apparatus, receives the first map information from the CPU and, based on the first map information, extracts the first file data from the block data, and the communication processing unit transmits the first file data to the network. | 01-09-2014 |
