摘要:
A method of distributing contents in a system including a distribution station for distributing contents, a relay station for relaying the contents, a management apparatus for receiving the contents distributed from the distribution station or the relay station and managing the contents, and a plurality of terminal apparatuses for receiving the contents distributed from the management apparatus, the method comprising the steps of: attaching metadata to the contents distributed from the distribution station; and adding location information of the relay station, the management apparatus or each of the terminal apparatuses to the metadata of the contents when the contents are stored in the relay station, the management apparatus or the terminal apparatus. The contents can be displayed on the user side concentratedly regardless of locations of the contents so that the contents can be acquired or played back without user's consciousness of locations of the large number of contents.

摘要:
The broadcast equipment is provided with a receiving unit (101), a separation processing unit (102) for separating the broadcast signal into a program content and control information, a content processing unit (103) for processing the program content, a erasing unit (104) for erasing the AIT included in the control information, a storage (105) for storing the AIT working with the program content, a readout unit (106) for reading out an AIT from the storage (105), an adding unit (107) for adding the AIT read out by the readout unit (106) to the control information from which the AIT is erased by the erasing unit (104), a multiplexing processing unit (108) for multiplexing the control information to which the AIT is newly added and the program content after being processed by the content processing unit (103), and a transmitting unit (109) for transmitting the multiplexed signal as a broadcast signal.
摘要:
A terminal (5) obtains, by communicating with a viewer history presence management server (101) that manages viewing histories of multiple users including the user of said terminal, viewing histories of the different users from the viewer history presence management server (101); generates GUI video data, in which more than one symbols respectively corresponding to more than one program content viewed by the other viewers are listed chronologically, on the basis of the viewing histories of the different users; and outputs the video data for presentation. In this case, upon receiving a specific symbol selected by the user among the one or more symbols contained in the GUI video data, the terminal (5) transmits a command to a receiver so as to switch the program to be reproduced at the receiver to the program content which corresponds to the specific symbol received by an operation reception unit (77).

A receiver includes: a terminal-side server unit configured to receive a request output by a device executing an application; a receiver-side server unit configured to receive a request output by an application execution unit executing an application; a connecting unit configured to establish connection among the terminal-side server unit or the receiver side-server unit, the application execution unit, and the terminal; and a bridge unit configured to bridge-connect the terminal-side server unit and the receiver-side server unit via the connection established by the connecting unit.
摘要:
The receiver (4) is provided with: a menu generation unit (191) that identifies, in response to receipt of a prescribed operation, executable applications on the basis of a viewing state detected by a viewing state detection unit (18) and executable information included in an AIT, and generates a menu screen including information about the identified applications; a display control unit (21) that conducts display control by compositing the menu screen and program content; and an application execution control unit (192) that acquires, in response to an application selecting operation received by an operation receiving unit (17) after the menu screen has been composited with the program content by the display control unit (21), the selected application from a service server (3) on the basis of location information in the AIT that corresponds to the selected application, and executes the selected application.
摘要:
Provided are a signal processing device and a program which is capable of switching from a broadcast program to VOD, and during viewing of the VOD, if an emergency alert is superimposed upon a broadcast wave, displays the emergency alert under certain conditions, and which additionally is capable of displaying only VOD when viewing a recording. This signal processing device (4), on the basis of a signal from a remote control (R), upon switching to VOD content on the basis of an AIT in order to display the content upon a display (21), in response to detection of a boot flag for an emergency alert broadcast for a TMCC carrier included in a broadcast wave of a broadcasting station before the switching, displays the emergency alert broadcast included in the broadcast wave upon the display (21).
