An alibi is a type of defense found in legal proceedings by demonstrating that the defendant was not in the place where an alleged offense was committed. There may be legal ramifications for not disclosing a true alibi defense, as well as penalties for providing a false alibi.
An alibi is a judicial mode of defense under which a defendant proves or attempts to prove that he/she was in another place when a crime was committed; as, to set up an alibi; to prove an alibi. The Criminal Law Deskbook of Criminal Procedure states: "Alibi is different from all of the other defenses; it is based upon the premise that the defendant is truly innocent." In the Latin language alibī means "somewhere else."
In some legal jurisdictions there may be a requirement that the defence disclose an alibi defence prior to a trial.
In Canada, the defence must disclose an alibi defence with sufficient time for the authorities to investigate the alibi, and with sufficient particularization to allow for a meaningful investigation. Failure to comply with the two requirements will result in the court making an adverse inference against the alibi defence (but will not result in the exclusion of the alibi defence).
A television channel is a physical or virtual channel over which a television station or television network is distributed. For example, in North America, "channel 2" refers to the broadcast or cable band of 54 to 60 MHz, with carrier frequencies of 55.25 MHz for NTSC analog video (VSB) and 59.75 MHz for analog audio (FM), or 55.31 MHz for digital ATSC (8VSB). Channels may be shared by many different television stations or cable-distributed channels depending on the location and service provider.
Depending on the multinational bandplan for a given region, analog television channels are typically 6, 7, or 8 MHz in bandwidth, and therefore television channel frequencies vary as well. Channel numbering is also different. Digital television channels are the same for legacy reasons, however through multiplexing, each physical radio frequency (RF) channel can carry several digital subchannels. On satellites, each transponder normally carries one channel, however small, independent channels can be used on each transponder, with some loss of bandwidth due to the need for guard bands between unrelated transmissions. ISDB, used in Japan and Brazil, has a similar segmented mode.
