Methods and apparatus for transcoding metadata are disclosed. Example apparatus disclosed herein include means for accessing first metadata accompanying media to be presented by a media device, the first metadata in a first format not detectable by a meter collecting audience measurement data associated with the media device. The example apparatus also include means for transcoding the first metadata into second metadata having a second format different from the first format, the second metadata detectable by the meter and supported by an application programming interface (API) provided by the media device and accessible by the meter. The example apparatus further include means for communicating the second metadata in a second transmission for receipt by the meter via the API provided by the media device, the second transmission being separate from a first transmission communicating the media and the first metadata, but not communicating the second metadata, to the media device.

Disclosed herein is a reception apparatus including: a reception block configured to receive AV content; a trigger information capture block configured to capture trigger information for controlling an operation of an application program to be executed in coordination with said AV content; and a control block configured to control an operation of said application program in accordance with an operation mode specified in said trigger information.

Disclosed herein is a reception apparatus including: a reception block configured to receive AV content; a trigger information capture block configured to capture trigger information for controlling an operation of an application program to be executed in coordination with said AV content; and a control block configured to control an operation of said application program in accordance with an operation mode specified in said trigger information.

According to an aspect, there is provided a digital television (DTV) data stream including program and system information protocol (PSIP) data associated with content of the DTV data stream, the PSIP data including a virtual channel table (VCT) and an event information table (EIT), the EIT comprising: a source identification field identifying a source of an associated event in a DTV data stream; an event identification field indicating an identification of the event; a start time field indicating a star time of the event; a title field indicating a title of the event; and a descriptor comprising: a descriptor tag identifying the descriptor as a genre descriptor; a descriptor length indicating a total length of the descriptor; and at least one category code for an associated event in a DTV data stream, each category code specifying genre, program type, or category information of the associated event, wherein the at least one category code specifies at least one of a set of basic categories.

Methods of presenting video and audio perspectives of audio/video content are presented. In an example embodiment, audio/video content having a plurality of video perspectives and a plurality of audio perspectives of an event is received. Responsive to a first command from a media application configured to allow a user to select among the plurality of video perspectives, a selected first video perspective of the event is provided for presentation. Responsive to a second command from the media application that is also configured to allow a user to select among the plurality of audio perspectives, a selected first audio perspective of the event is associated with the selected first video perspective of the event, and the selected first audio perspective is provided for presentation in association with the selected first video perspective of the event.

A method for providing video and audio perspectives of audio/video content is presented. In an example embodiment, a media content item is received that includes audio/video content having at least one video perspective and a plurality of audio perspectives for the at least one video perspective. The at least one video perspective is provided with a first one of the plurality of audio perspectives for presentation on a display device. During the providing of the at least one video perspective with the first one of the plurality of audio perspectives, a first command is received from a media application configured to allow a user to select among the plurality of audio perspectives. Responsive to the first command, the video perspective is provided along with a selected second one of the plurality of audio perspectives in substitution of the first one of the plurality of audio perspectives for presentation on the display device.

It is determined that a substantial portion of set-top terminals connected to a video content network require a software upgrade. In-band video bandwidth (e.g., video-on-demand or switched digital video) is allocated for the software upgrade. The software upgrade is broadcast to the set-top terminals from a carousel in a first remote node of the video content network, via the allocated in-band video bandwidth, until a predetermined number of the set-top terminals have received the software upgrade. Subsequent to the predetermined number of set-top terminals receiving the software upgrade, the in-band video bandwidth is de-allocated and the software upgrade is made available out-of-band to the remaining portion of the set-top terminals, via individual sessions with an application server in a second remote node of the video content network. An exemplary system, which can implement the method, includes a controller, a dynamic bandwidth allocation device, the carousel, and the application server.

Disclosed herein is a receiving device for receiving an AV content broadcast by a broadcasting wave, including: an obtaining section adapted to obtain a description document described in a predetermined computer language for displaying another content different from the AV content; a determining section adapted to determine whether the obtained description document is managed by a broadcaster which broadcasts the AV content or is managed by a different operator other than the broadcaster; and a controlling section adapted to control execution of the obtained description document in response to a result of the determination by the determining section.

Methods and apparatus for transcoding metadata are disclosed. Example apparatus disclosed herein include means for accessing first metadata accompanying media to be presented by a media device, the first metadata in a first format not detectable by a meter collecting audience measurement data associated with the media device. The example apparatus also include means for transcoding the first metadata into second metadata having a second format different from the first format, the second metadata detectable by the meter and supported by an application programming interface (API) provided by the media device and accessible by the meter. The example apparatus further include means for communicating the second metadata in a second transmission for receipt by the meter via the API provided by the media device, the second transmission being separate from a first transmission communicating the media and the first metadata, but not communicating the second metadata, to the media device.

A method for receiving a broadcasting service according to the present invention comprises the steps of: receiving service signaling data for receiving a object; receiving network property information related to the object if the object that is to be received exists; determining whether the object is received according to network connection status of an apparatus for receiving a broadcast and the received network property information; receiving the object based on the service signaling data; receiving a first packetized stream; extracting a trigger including a trigger action and trigger time from a payload of the first packetized stream; and performing the trigger action in response to the object at the predetermined time using the trigger time based on the network property information.
