Transmission parameter information
View Patent ↗According to an embodiment of the invention, an apparatus includes a decoder configured to decode transmission parameter signaling data from a signal, the signal including the transmission parameter signaling data on a lower level than a level on which service information is included; and a determiner configured to determine from decoded transmission parameter signaling data if the signal carries time-sliced elementary streams and configured to determine from the decoded transmission parameter signaling data whether the signal has a forward error correction framing structure, wherein the apparatus is a receiver and is configured to operate in a network. The apparatus further includes a controller configured to disregard a signal in response to determining that the signal does not carry time-sliced elementary streams.
1. A method comprising:
decoding in a receiver transmission parameter signaling data from a signal, the transmission parameter signaling data comprising a predetermined number of data bits defined over consecutive orthogonal frequency division multiplex symbols, the transmission parameter signaling data comprising at a predetermined location a group of information bits having a state dependent on whether the signal to which the transmission parameter signaling data relates carries time-sliced elementary streams having a forward error correction framing structure;
determining from the group of information bits at the predetermined location if the signal carries time-sliced elementary streams; and
determining from the group of information bits at the predetermined location whether the signal has a forward error correction framing structure.
