Transmitting apparatus and transmission method

A transmission method for transmitting user data, the method comprising:

• a step A of establishing three or more transmission paths for a receiving apparatus;
• a step B of generating a user data unit which is a data unit including user data to be transmitted to the receiving apparatus;
• and
• a step C of generating an error correction data unit which is a data unit including error correction data to be used for error correction of the user data to be transmitted to the receiving apparatus, wherein
• at least one of the three or more transmission paths is a transmission path for transmitting the error correction data unit,
• at least two of the three or more transmission paths are transmission paths for transmitting the user data unit
• the error correction data includes first error correction data to be used for error correction of the user data to be transmitted to the receiving apparatus, and second error correction data to be used for error correction of the user data to be transmitted to the receiving apparatus,
• the transmission path for transmitting the error correction data unit includes a transmission path for transmitting an error correction data unit including the first error correction data, and a transmission path for transmitting an error correction data unit including the second error correction data,
• the first error correction data is generated by a method different from a method used for generating the second error correction data, and
• the first and second error correction data are respectively generated from at least two streams of the user data unit.
