    摘要: Aspects of the invention provide apparatuses, computer media, and methods for supporting the broadcast of signaling data over a network. Error detection and protection as well as modulation mechanisms enhance the flexibility and robustness of signaling data for digital video broadcasting. A first error detection code for a first portion of signaling data and a second error detection code for a second portion of the signaling data are determined. The signaling data is combined with data and transmitted as a digital stream through a digital terrestrial television broadcasting system. A portion of the signaling data may include a configurable part and a dynamic part or may include different dynamic parts of the signaling data. Different portions of the signaling data may be separately modulated and encoded. A portion of the signaling data may be divided over a plurality of code words and evenly distributed over a transmission period.

    摘要: 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 P2 symbol.

    摘要: 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.

    摘要: 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.

    摘要: A method is provided for controlling information detail in a multi-device environment. In particular, example methods may provide for operating a device in a multi-device environment, directing the presentation, on a display of the device, of a first image, detecting a motion of the device, directing a change of the image presented on the display of the device from the first image to a second image in response to detecting the motion of the device. The first image presented on the device is related to images displayed on other devices in the multi-device environment. The second image may be a scaled version of the first image and the second image may be scaled based on at least one property of the motion. Each device in the multi-device environment may be directed to display a portion of a complete image, where the first image is a portion of the complete image.
