A transmitting apparatus is provided. The transmitting apparatus includes: a frame generator configured to generate a frame including a plurality of orthogonal frequency-division multiplexing (OFDM) symbols; and a guard interval (GI) inserter configured to insert GIs into the generated frame, wherein the plurality of OFDM symbols are divided into a bootstrap, a preamble, and a payload, and the GI inserter inserts first GIs having a size corresponding to a fast Fourier transform (FFT) size of each of OFDM symbols configuring the payload into front ends of each of the OFDM symbols, inserts second GIs having a size corresponding to a quotient obtained by dividing an extra region of the payload calculated based on the FFT size of the OFDM symbols configuring the payload, the number of OFDM symbols, and the size of the first GIs by the number of OFDM symbols into front ends of each of the first GIs, and inserts a cyclic postfix (CP) having a size corresponding to the remainder remaining after dividing the extra region of the payload by the number of OFDM symbols into a rear end of a final OFDM symbol configuring the payload.

A method is described for selecting and displaying, on or through a television signal receiver apparatus capable of connecting to Internet and of pointing to URL's, television programs transmitted through an Internet network, said method comprises the step of associating at least one URL, or Uniform Resource Locator, corresponding to streaming audio/video of a specific television program, with the same television program of an EPG, or Electronic Program Guide, received by said apparatus via television broadcast, and wherein said association requires that said URL be stored into a memory-type processing circuit of the apparatus to create a link between said specific television program received through said Internet network and the same specific television program of said EPG received by said television receiver apparatus via television broadcast.

There is provided an arrangement which is capable of reliably generating and transmitting viewing information with respect to contents received via a communication route other than terrestrial broadcasting waves. Contents in which a contents ID applicable to the generation of viewing information and viewing information-compatible data such as viewing information destination information or the like are recorded in an electronic watermark (WaterMark) or a sound data file are sent from a transmitting apparatus to a receiving apparatus. The receiving apparatus acquires the contents ID and the viewing information destination information, etc. from the electronic watermark (WM) or the sound data file, generates viewing information using the acquired data, and sends the generated viewing information to a designated address.
