Patent number: 8243659Abstract: 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.Type: GrantFiled: March 15, 2007Date of Patent: August 14, 2012Assignee: Nokia CorporationInventors: Jukka Henriksson, Jussi Vesma, Jani Väre, Harri J.

Patent number: 8218559Abstract: In accordance with an embodiment, a best-effort service is divided into packets for best-effort digital broadcast transmission. The packets are encapsulated with an encapsulation protocol that uses a packet order defining field. The encapsulated packets are inserted into an unused portion of a slot of a digital broadcast transmission frame. Then, the encapsulated packets are repeatedly inserted into the unused portion of the slot of the digital broadcast transmission frame in a packet-carousel fashion. And the transmission frame is digitally broadcast. In accordance with an embodiment, a digital broadcast transmission is received. Encapsulated packets that have been repeatedly broadcast in a packet-carousel fashion are accessed from a best-effort portion of a digital broadcast transmission frame slot. And a best-effort service is composed from the encapsulated packets by combining the encapsulated packets in an order based on a packet order defining field of the encapsulated packets.Type: GrantFiled: May 15, 2007Date of Patent: July 10, 2012Assignee: Nokia CorporationInventors: Jani Vare, Jussi Vesma, Harri Pekonen, Tommi Auranen

Patent number: 8213383Abstract: 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.Type: GrantFiled: September 4, 2008Date of Patent: July 3, 2012Assignee: Nokia CorporationInventors: Harri J.

Patent number: 8159982Abstract: A method, a system, a transmitter and a receiver for identification of a time sliced elementary streams using PSI/SI tables. This identification provides a way to separate time-sliced elementary stream from non-time-sliced elementary streams by defining two descriptors in PSI/SI tables. A time slice identifier descriptor is defined, which can be used to identify elementary streams which are time sliced. This descriptor is also used to provide additional information about the transmitted elementary streams. The invention provides a way to announce additional information of the time sliced elementary streams via PSI/SI tables. Additionally, it provides a mechanism to categorize single elementary stream(s) as non-time sliced and time sliced. A way to identify time sliced elementary streams carried over DVB networks is disclosed and providing additional information on those streams. This can be done by using the time slice identifier descriptor.Type: GrantFiled: January 21, 2003Date of Patent: April 17, 2012Assignee: Nokia CorporationInventors: Jani Väre, Matti Puputti, Harri Pekonen, Kimmo Laiho, Tommi Auranen

Patent number: 8155115Abstract: A method for transmission, a method for reception, a system, a transmitter and a receiver for signalling a hierarchical priority mapping of a transport stream (TS) to a receiver is disclosed. A way to separate tuning information between different TSs with different priorities. In a wireless hierarchical broadband transmission, preferably based on DVB-T, one signal may carry two transport streams: low priority (LP) stream and high priority (HP) stream, and both should be identified with their own respective transport_stream_id. One bit flag is added into a certain descriptor of the broadband transmission to indicate the hierarchy of the transport stream on which said descriptor is providing information. By the appliance of this priority indication or priority flag, the receiver can obtain hierarchy mapping of each transport stream announced in the administrative information of the broadband transmission.Type: GrantFiled: March 3, 2003Date of Patent: April 10, 2012Assignee: Nokia CorporationInventors: Jarno Kallio, Jani Vare, Arto Hamara

Patent number: 7974254Abstract: 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.Type: GrantFiled: October 22, 2007Date of Patent: July 5, 2011Assignee: Nokia CorporationInventors: Jani Vare, Jussi Vesma, Tero Jokela

Publication number: 20110055887Abstract: Broadcast services and other transmissions may conform to multiple types of protocols. Accordingly, a broadcast system may tunnel broadcasts or transmissions of a first protocol in a transport stream conforming to a second protocol. Each of the tunneled streams may be multicast together and may correspond to a separate and different physical layer pipe. The types of protocols and physical layer pipes carried in the transport stream may be defined in a pre-signaling section and/or post-signaling section of the transport stream. Common physical layer pipes may be generated and included in the transport stream to carry information and data common to multiple broadcast services or transmissions such as program specific information or service information.Type: ApplicationFiled: August 16, 2010Publication date: March 3, 2011Applicant: NOKIA CORPORATIONInventors: Jani Väre, Jyrki Alamaunu
