Technologies are disclosed for providing stream media content and/or metadata indicating stream media content. A media control device may receive a Digital Living Network Alliance (DLNA) hypertext transport protocol (HTTP) request from a media content device. The DLNA HTTP request may have a header created by the media content device. The media control device may interpret the DLNA HTTP request header. A first metadata may be identified in the DLNA HTTP request header that may indicate a request for stream media content information. The media control device may send a DLNA HTTP response to the media content device. The DLNA HTTP response may have a header that may include a second metadata indicating the stream media content information. The second metadata may include information enabling construction of a HTTP Live Streaming (HLS) master playlist, a program map table, and/or a program association table associated with the stream media content.

Methods, systems, and apparatus for processing of three-dimensional visual content are described. One example method of processing three-dimensional content includes parsing a level of detail (LoD) information of a bitstream containing three-dimensional (3D) content that is represented as one geometry sub-bitstream and one or more attribute sub-bitstreams; and generating, based on the LoD information, decoded information by decoding at least a portion of the geometry sub-bitstream and the one or more attribute sub-bitstreams corresponding to a desired level of detail; and reconstructing, using the decoded information, a three-dimensional scene corresponding at least to the desired level of detail. The bitstream conforms to a format organized according to multiple levels of details of the 3D content.

Video content is uploaded via the Internet to a video-on-demand (VOD) server identified by a title and a hierarchical address of categories and subcategories for categorizing the title. The VOD server converts and stores the video content at a storage address in a video content database linked to the title. The title is listed in a location of an electronic program guide (EPG) using the same categories and subcategories as in its hierarchical address. Any TV subscriber can access the EPG and navigate through its categories and subcategories to find a title for viewing on the TV. This can enable many new blogging or podcasting-like programs by popular “Hosts” to be self-published on the Internet and readily navigated for display on TV. The EPG can also store TV program addresses as bookmarks and allow them to be shared with other subscribers or with friends and contacts online by sending to their email addresses.

Aspects of the subject disclosure may include, for example, identifying a media program and receiving a digital media stream including metadata and payload data, wherein the payload data includes program content of the identified media program. The metadata further includes program event information and program status information related to the identified media program. A recording status of the identified media program is determined, wherein an active recording status indicates the identified media program is being recorded at a media recorder. Responsive to the active recording status, an end of program is determined according to the identified media program, the program event information and the program status information. Responsive to the end of program, termination of the recording of the media program is initiated. Other embodiments are disclosed.

The present technology relates to a receiver for efficiently acquiring a component configuring a service, a reception method, a transmitter, and a transmission method. The receiver acquires first signaling data distributed on a broadcast wave of digital broadcasting in an IP transmission system, acquires broadcast signaling data as second signaling data, acquires communication signaling data as the second signaling data when flag information included in the broadcast signaling data indicates that the communication signaling data is provided from a server over the Internet together with the broadcast signaling data, and connects to a stream of a broadcast component or a stream of a communication component thereby to control reproduction of the component on the basis of at least one of the broadcast signaling data and the communication signaling data. The present technology is applicable to TV receivers, for example.

A reception apparatus including reception circuitry and processing circuitry is provided. The reception circuitry is configured to receive control information and content, the control information including resource sharing information indicating whether a resource is shared among a plurality of applications. The processing circuitry is configured to control, based on the resource sharing information, sharing of the resource among the plurality of applications. The resource sharing information includes an identifier that is associated with the plurality of applications among which the resource is shared. The resource includes at least one file associated with at least one of the plurality of applications.

A reception apparatus receives a content transmitted in an IP transmission system, acquires, based on first control information that is transmitted in a first layer in a protocol stack of the IP transmission system and includes information indicating whether second control information transmitted in a second layer higher than the first layer exists, the second control information, and controls operations of units that process the content based on the second control information.

Examples of video encoding methods and apparatus and video decoding methods and apparatus are described. An example method of video processing includes performing a conversion between a video including one or more layers and a bitstream of the video according to a rule, wherein the rule specifies, in a process of sub-bitstream extraction to output an output sub-bitstream, whether to generate non-scalable nested supplementary enhancement information (SEI) messages by extracting scalable-nested SEI messages from a scalable nesting SEI message based on a first flag indicating whether the SEI message applies to specific output layer sets (OLSs) and a second flag indicating whether the SEI message applies to all subpictures or only to specific subpictures.

In various embodiments, a Data Processing System for Generating Interactive User Interfaces and Interactive Game Systems Based on Spatiotemporal Analysis of Video Content may be configured to: (1) enable a user to select one or more players participating in a substantially live (e.g., live) sporting or other event; (2) determine scoring data for each of the one or more selected players during the sporting or other event; (3) track the determined scoring data; (4) generate a custom (e.g., to the user) user interface that includes the scoring data; and (5) display the custom user interface over at least a portion of a display screen (e.g., on a mobile computing device) displaying one or more video feeds of the sporting or other event. In this way, the system may be configured to convert a video feed of a sporting event into an interactive game.

A set-top box receives original video streams and generates a guide video stream that includes each of the original video streams resized and arranged as a plurality of scaled video streams such that all of the scaled video streams are simultaneously visible and playing on the guide video stream. The guide video stream is displayed on a display device and the set-top box provides an interactive user interface on the display device in conjunction with the guide video stream to allow a user of the set-top box to select one of the scaled video streams for full screen playback. In response to the user selecting a particular scaled video stream on the guide video stream for full screen playback, the set-top box plays full screen on the display device a particular original video stream corresponding to the particular scaled video stream as received via the communication interface.
