  • Patent number: 8774225
    Abstract: Services and service components in a broadcast network may be mapped to disparate physical layer transmission channels (PLPs) using logical layer pipes (LLPs). The use of LLPs allows different service components of a single service to be mapped to physical layer transmission channels (PLPs). Accordingly, service components may be shared among different services. Additionally or alternatively, different functions (e.g., different error detection or correction protocols) may be applied to each service components of a service. A receiver may identify services, service components and corresponding PLPs based on LLP identifiers. The receiver may then access and receive desired services and service components through the identified PLPs.

  • Patent number: 8670372
    Abstract: A system and method for dynamically dividing the capacity of a fixed time division multiplexing (TDM) frame between physical channels for data transmission. According to various embodiments, a time frequency frame is divided into a plurality of subframes, and each of the plurality of subframes are divided into a plurality of corresponding slots. The plurality of slots are then selectively time shifted such that a defined time shift exists between corresponding slots in each subframe within the time frequency frame. For any slots or slot portions which have been selectively shifted beyond the end of the time frequency frame, such slots or slot portions are cyclically shifted to the beginning of the frame. Service data is then written into the slots of the time frequency frame, and the frame containing the service data can then be transmitted. Initialization and service access processes for a receiver are also provided.

  • Patent number: 8498262
    Abstract: Embodiments are directed to transmitting receiver-capacity-signalling data that specifies a plurality of receiver capacities to be used for receiving a service. The signalled receiver capacities may include: a type of time interleaver being used and a minimum burst interval between two consequent bursts. The signaled receiver capacities may also specify: how often a physical layer pipe appears in frames, and/or a number of a frame in which a physical layer pipe appears for a first time during a super frame. Embodiments are directed to receiving the receiver-capacity-signalling data and if, based on the received receiver-capacity-signalling data, receiver capacity is sufficient for one or more selected services, performing service discovery and decoding the one or more services. Otherwise, decoding the one or more services may not be performed.

  • Patent number: 8248910
    Abstract: 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.

  • Patent number: 8243659
    Abstract: The invention is directed to efficient transfer of low bit rate services in a communication system. A synchronization symbol which has known characteristics may be included as a first symbol of digital broadcast frames. The synchronization symbol, which can be decoded without having to resort to trial and error methods, contains parameters for the rest of the signal. Low bit rate services are allocated to time slots following the pilot symbol used for synchronization allowing for fast access times with maximum power saving capabilities. A user terminal wakes up just before the synchronization symbol and received the data allocated for the low bit rate services. The user terminal may power off for the remaining time slots which are allocated for higher bit services to conserve power.

  • Patent number: 8230293
    Abstract: A receiver is arranged to start receiving a data frame 80 including application data followed by parity data. An erasure information table is generated, and includes one element for each element of a data frame 80. If there are no errors in the application data, the receiver is powered-down to sleep without receiving the parity data, and the application data is used without correction being needed. If the number of errors in the application and parity data exceeds the MPE-FEC correction capability, the receiver is powered-down to sleep without further parity data being received and the data is not decoded. If the number of errors is smaller than the MPE-FEC correction capability, the receiver is powered-down to sleep when sufficient parity data is received to correct errors in the application and parity data. This can save power in the receiver. In another embodiment, the erasure information table includes one element for each column of a data frame.

  • Patent number: 8213383
    Abstract: A system and method is provided for ensuring that time for tuning to another RF channel between two TF frames in TF slicing exists while reception with a single hopping-tuner is enabled, and reception for terminals can be guaranteed when transmitting and receiving common services. An additional time for tuning is introduced for TF-sliced services, where the time for tuning can be inserted either before of after the P1 & P2 symbols, and the symbols allocated for the tuning time can also be used for transmission of low-bit rate services. Alternatively, additional padding bits and a guard period can be added in the event that slots or slot fragments exceed a cyclic transfer border upon time shifting. Alternatively still, the tuning time is represented by a complete TF frame, where the complete TF frame carries services other than those in the first TF frame, so that a service is transmitted in every second TF frame and a receiver can perform tuning during the TF frames which do not carry the service.

  • Patent number: 8208437
    Abstract: A system and method for improved scheduling for time-frequency slicing. According to various embodiments, slot allocations are made so as to guarantee time for tuning between slots. When scheduling services for multiplexes covering multiple radio frequency (RF) channels, time is provided for the receiver to tune to another radio-frequency channel between at least two of the time frequency frames. This is accomplished by arranging slots so that a service carried in a slot within the tuning time before the end of a time frequency frame k is not transmitted in a slot within the tuning time after the beginning of the next time frequency frame k+1.

  • Patent number: 8009685
    Abstract: Aspects of the invention are directed to signalling extension frames in a telecommunication system. Extension-frame-signalling data may signal whether one or more extension parts are present in one or more gaps in time between data frames, when the one or more extension parts occur, and one or more durations for the one or more extension parts. The one or more extension parts may occur on the same radio frequencies as the data frames. The extension-frame-signalling data may signal when the one or more extension parts occur by signalling after which of one or more data frames in a super frame the extension parts occur. The one or more durations for the extension parts may be expressed in units of time.

  • Patent number: 7848328
    Abstract: Components of a transmitted service delivering multiple versions of content are mapped to streams carrying data for those multiple versions. The data streams are encapsulated into User Datagram Protocol (UDP) packets; the UDP destination port fields of the packets are given component-identifying values. A user equipment (UE) receiving the transmitted service identifies desired components based on the UDP destination port field values. The UE further encapsulates desired component UDP packets into Internet Protocol (IP) packets, and may assign component-identifying values to fields of the IP packets (e.g., the IP source address and/or IP destination address).

  • Patent number: 7823048
    Abstract: Data for a second Multi-Protocol Encapsulation-Forward Error Correcting (MPE-FEC) data frame is received while application data from a first MPE-FEC frame is undergoing error correction. The incoming data is buffered in a supplemental buffer having a size smaller than that needed for an entire MPE-FEC frame. As the supplemental buffer is filled, additional data from the second frame is stored in a buffer previously used to store error correction data for the first MPE-FEC frame. When corrected application data from the first MPE-FEC frame is transferred from an application data buffer used to hold application data undergoing correction, the second MPE-FEC frame data is transferred from the supplemental and error correction data buffers to the application data buffer. Additional data for the second frame is then placed directly into the application and error correction data buffers.
