Certain examples of the present invention relate to an apparatus, method, computer program and system for use in gaze dependent foveated rendering. Certain examples provide an apparatus including at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform adapting a gaze dependent foveated rendering process in response to a determination of a sub-optimal operational condition of the gaze dependent foveated rendering process.

An approach is provided for sharing media in a multi-device environment. A group of devices for sharing one or more media files is determined. A shared media manager causes joining of one or more displays of the devices. The shared media manager then determines to generate a common user interface for presenting the one or more media files on the joined one or more displays.

Method and apparatus for sharing media in a multi-device environment

An approach is provided for creating a virtual workspace among devices based, at least in part, on location information. The virtual workspace corresponds to an application or a service common to the devices. Monitoring of the movement of one or more of the devices causes manipulation of the virtual workspace, the application, the service, or a combination thereof based, at least in part, on the movement. Example applications and services include media editing, media playback, image processing, social networking, and social control functionality.

Aspects of the invention provide apparatuses, computer media, and methods for supporting the broadcast of signaling data over a network. Signaling data is encoded, partitioned into M signaling segments, and distributed over M corresponding data frames. A data stream with the partitioned signaling data is transmitted through a digital terrestrial television broadcasting system, where the partitioned signaling data may include physical layer configurable data. The number of distributed signaling segments may be determined from a predetermined value or from a parameter contained in pre-signaling data. The number of physical layer pipes supported by signaling data may be increased by separating the static signaling part and the dynamic signaling part, dividing static signaling part into signaling segments, and interleaving the signaling segments over the data frames. The number of physical layer pipes can be further increased by adding at least one Psymbol.

Aspects of the invention provide apparatuses, computer media, and methods for supporting the broadcast of extended signaling data over a network. With an aspect of the invention, all of the extended signaling data may be distributed over multiple data frames. With another aspect, only dynamic signaling redundancy data is distributed over different data frames, where systematic information (for example, configurable signaling data) is transmitted in accordance with traditional systems. In addition, backwards compatibility with traditional systems may be supported, in which extended signaling is contained in an extension field. Error correction code may be applied to the extended signaling in concert with different codes. With another aspect, only extended signaling is supported without backwards compatibility with traditional systems.

Aspects of the invention are directed to physical layer and data link layer signaling in digital video broadcast preamble symbols. Embodiments are directed to distributing physical layer pre-signalling data among preamble symbols. If physical layer data is larger than a predetermined number of preamble symbols, then excess physical layer data is written to data symbols immediately following the preamble symbols in top-down order symbol by symbol or the predetermined number of preamble symbols is increased. If physical layer data is not larger than the predetermined number of preamble symbols such that there is excess preamble symbol space, physical layer pipe 0 data comprising link layer signaling and notification data is carried in the excess preamble symbols or the excess preamble symbols are left empty. Different permutation rules may be used to frequency interleave odd-numbered versus even-numbered orthogonal frequency division multiplexing symbols.

Embodiments are directed to transmitting L1 pre-signaling information with predetermined modulation and code rate such that L1 pre-signaling information can be received without preliminary knowledge on the network. L1 pre-signaling information makes it possible to receive the L1 signaling information, data link layer information, and notification data that may have configurable code rates and modulation. Therefore, L1 pre-signaling information can be thought of as signaling metadata (i.e., information about other signaling information). L1 signaling is divided into pre-signaling and signaling parts. The pre-signaling part includes parameters used for receiving the L1 signaling information. L1 pre-signaling signaling enables the receiver to receive the signaling itself (L1 signaling and data link layer information) by informing the receiver about the type of modulation, coding, and the like, used to transmit the L1 signaling, data link layer, and notification information.
