The invention provides an internet-oriented large-scale live time shifting method based on fragment transmission. The method comprises the steps that a client-side sends a time shifting request to obtain fragment index files; a time shifting server-side obtains time shifting status marks through time shifting time points; the client-side sends an acquisition request for the fragment index files to the time shifting server-side after receiving feedback from the time shifting server-side; the time shifting server-side processes the acquisition request for the fragment index files to obtain fragment sequences of the time shifting request this time; the time shifting server-side generates corresponding live fragment index files through the fragment sequences and returns the live fragment index files to the client-side; the client-side obtains the specific fragment sequences from the index files, downloads and plays the actual fragment files and repeatedly sends the same acquisition request for the fragment index files. A system where the method is implemented comprises the time shifting server-side and the client-side. The client side is simple and easy to implement, the time shifting index range required to be obtained does not need calculating, and time shifting indexes obtained each time do not need to be reserved or merged.

Generating an fsk signal comprised in an OFDM signal

A method is disclosed of generating a frequency shift keying (FSK) signal comprised in an orthogonal frequency division multiplexing (OFDM) signal comprising a plurality of sub-carriers. The FSK signal comprises FSK symbols wherein each FSK symbol has a corresponding FSK symbol frequency. The method comprises assigning (310) a set of adjacent sub-carriers to transmission of the FSK signal (whereinthe set is a sub-set of the plurality of sub-carriers), and associating each FSK symbol frequency with a corresponding sub-carrier in the set of adjacent sub-carriers. The method also comprises selecting (330), for each FSK symbol (201, 202, 203) to be transmitted, an FSK symbol phase such that an FSK signal phase at a start (252) of the FSK symbol (202) to be transmitted meets a phase differencecriterion in relation to the FSK signal phase at an end (251) of an immediately previous FSK symbol (201). The method further comprises generating (340) the FSK signal comprising the FSK symbol to betransmitted by modulating the sub-carrier corresponding to the FSK symbol frequency based on the selected FSK symbol phase and muting the remaining sub-carriers of the set. Corresponding arrangement,access point and computer program product are also disclosed.
