A method includes allocating frame capacity between physical layer pipes dividing a frame and physical layer pipes into a plurality of subframes, wherein each subframe carries one burst from each physical layer pipe; selectively time shifting the plurality of bursts such that a defined time shift exists between corresponding bursts in each subframe within the frame; and appending the subframes after each other in a sequence. Each frame may include two or more radio frequency channels, each radio frequency channel including subframes. The method may further include selectively time shifting one or more of the radio frequency channels such that a defined time shift exists between corresponding radio frequency channels in each frame; and for any subframes of a radio frequency channel which have been selectively shifted beyond the end of the frame, cyclically shifting such subframes to the beginning of the frame.

System and method for burst separation and extended interleaving length

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 P& Psymbols, 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.

Method and system to guarantee service reception within broadcast system

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.

System and method for improved scheduling for time-frequency slicing

A method comprises dividing a time frequency frame into a plurality of slots, the frame having one or more radio-frequency (RF) channels, determining a maximum slot length, and scheduling service data in symbols such that all service data symbols are within the maximum slot length of symbols corresponding to at least one common service part.

Method and system to enable simultaneous reception of plurality of services in DVB systems

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.
