摘要:
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 (153) and synthesizing the data with the enhancement quality video to output the resulting data.

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.

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.

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.

A content provision system provides a content reproduction apparatus with content including main information which is at least either of video information and audio information generated by a content generation apparatus. The content generation apparatus generates a bodily sensation element by applying numeric conversion to characteristics of a bodily sensation given to a user, generates instruction information to reproduce the bodily sensation element in synchronism with reproduction of the main information, generates bodily sensation information by adding the instruction information to the bodily sensation element, and generates content including the bodily sensation information by adding the bodily sensation information to the main information. The content reproduction apparatus separates the main information and the bodily sensation information from the content, reproduces the main information, separates the bodily sensation element and the instruction information from the bodily sensation, and reproduces bodily sensation element based on the instruction information.

It is assumed that a reception processing unit receives a broadcast program in accordance with tuning based on the user's specification. In this state, a non-viewable state detection processing unit monitors occurrence of a non-viewable state from an acquisition state of reception data. When the non-viewable state occurs due to a certain factor, a non-viewable state accumulation unit accumulates information on the non-viewable state. When the factor of a viewing interruption is solved and a user makes a request for service provision, the processing unit connects to a distribution apparatus to report content of the non-viewable state, and receives distribution of a relevant content, thereby the processing unit becomes able to recontinue interrupted broadcast content.
摘要:
In a transport stream distribution system, a transmission rate control unit takes in an IP packet output from an IP transmission processing unit, obtains a TTS to be added to an arbitrary TS packet in the IP packet, and compares the TTS with a time stamp generated internally to determine whether both of them coincide with each other or not. And if they coincide with each other, the system takes in a TTS of the next TS packet, and otherwise, the system obtains a difference between a time indicating the TTS and the time indicating the internally generated time stamp to calculate a transmission rate correction value equivalent to the value of the difference, and issues the calculated correction value to the processing unit to correct a transmission rate.
