Transmission apparatus, AIT transmission method and reception apparatus

A transmission method, comprising:

• transmitting application data to a reception device based on a request, wherein the application data is associated with an application;
• and
• transmitting a first application profile of a plurality of application profiles to the reception device, based on the request, wherein
• the first application profile includes information of a plurality of function types of the application,
• the first application profile comprises a high-order bit region corresponding to a plurality of high-order bits of the first application profile and a low-order bit region corresponding to a plurality of low-order bits of the first application profile,
• a first function type of the plurality of function types of the application is set based on a correspondence of a first value of the high-order bit region with a first bit position of a plurality of bit positions in the low-order bit region,
• a total number of the plurality of function types in the first application profile is a multiplication product of a number of the plurality of high-order bits and a number of the plurality of low-order bits,
• the number of the plurality of high-order bits is equal to n and the number of the plurality of low-order bits is equal to 16−n, and
• n is a value in a range of 2-14.

A reception apparatus, comprising:

• reception circuitry to:
• receive application data of an application;
• and
• receive a first application profile of a plurality of application profiles, wherein
• the first application profile includes information of a plurality of function types of the application,
• the first application profile comprises a high-order bit region corresponding to a plurality of high-order bits of the first application profile and a low-order bit region corresponding to a plurality of low-order bits of the first application profile,
• a first function type of the plurality of function types of the application is set based on a correspondence of a first value of the high-order bit region with a first bit position of a plurality of bit positions in the low-order bit region;
• a total number of the plurality of function types in the first application profile is a multiplication product of a number of the plurality of high-order bits and a number of the plurality of low-order bits,
• the number of the plurality of high-order bits is equal to n and the number of the plurality of low-order bits is equal to 16-n, and
• n is a value in a range of 2-14;
• and
• decision circuitry that determines the first function type based on the first application profile.
