Transmitting method, receiving method, transmitting device, and receiving device
First Claim
1. A transmitting method implemented in a transmitting device, the method comprising:
- inputting, per unit time by an input terminal, a plurality of transfer packets less than or equal to a predetermined number;
transmitting, per the unit time by a transmitter, the plurality of transfer packets that have been input, in a state where definitions compliant with a receiving buffer model are satisfied, the definitions being predetermined for guaranteeing a buffering operation of a receiving device, wherein each of the plurality of transfer packets includes a variable-length packet header and a variable-length payload, and the definitions compliant with the receiving buffer model specify converting a first packet into a second packet and outputting the second packet from a buffer of the receiving device at a predetermined extraction rate, the first packet being included in the plurality of transfer packets received by the receiving device and including a variable-length packet header and a variable length payload, the second packet having a fixed-length packet header that is extended; and
storing, per predetermined data unit by a storage device, the plurality of transfer packets that have been input,wherein the unit time is one of a plurality of unit transfer periods which are consecutive and do not overlap with one another, andthe plurality of transfer packets to be transmitted are in the predetermined data unit used in the storing,wherein the plurality of transfer packets that have been input include;
a first transfer packet having a length that is within a predetermined length, and a second transfer packet having a length that exceeds the predetermined length,the storing includes;
setting, as a first packet count, the first transfer packets when storing the first transfer packet into the predetermined data unit,setting, as a second packet count, an integer value obtained by dividing a packet size of the second transfer packet by the predetermined length when storing the second transfer packet into the predetermined data unit, anda sum of the first packet count and the second packet count is less than or equal to the predetermined number.

Abstract
A transmitting method includes: inputting, per unit time, a plurality of transfer packets less than or equal to a predetermined number; and transmitting, per the unit time, the plurality of transfer packets that have been input, in a state where definitions compliant with a receiving buffer model are satisfied. Each of the plurality of transfer packets includes a variable-length packet header and a variable-length payload. The definitions compliant with the receiving buffer model are predetermined for guaranteeing a buffering operation of a receiving device, and specify converting a first packet into a second packet and outputting the second packet from a buffer of the receiving device at a predetermined extraction rate. The first packet is included in the transfer packets received and includes a variable-length packet header and a variable-length payload. The second packet has a fixed-length packet header that is extended.

6. A transmitting device comprising:
-
an input terminal into which a plurality of transfer packets less than or equal to a predetermined number are input per unit time; a transmitter which transmits, per the unit time, the plurality of transfer packets that have been input, in a state where definitions compliant with receiving buffer model are satisfied, the definitions being predetermined for guaranteeing a buffering operation of a receiving device, wherein each of the plurality of transfer packets includes a variable-length packet header and a variable-length payload, and the definitions compliant with the receiving buffer model specify converting a first packet into a second packet and outputting the second packet at a predetermined extraction rate from a buffer of the receiving device, the first packet being made up of a variable-length packet header and a variable-length payload and being included in the plurality of transfer packets received by the receiving device and including a variable-length packet header and a variable-length payload, the second packet having a fixed-length packet header that is extended; and a storage device which stores, per predetermined data unit, the plurality of transfer packets that have been input, wherein the unit time is one of a plurality of unit transfer periods which are consecutive and do not overlap with one another, and the plurality of transfer packets to be transmitted are in the predetermined data unit used in the storage device, wherein the plurality of transfer packets that have been input include; a first transfer packet having a length that is within a predetermined length, and a second transfer packet having a length that exceeds the predetermined length, the storage device which stores the plurality of transfer packets that have been input includes; setting, as a first packet count, the first transfer packets when storing the first transfer packet into the predetermined data unit, setting, as a second packet count, an integer value obtained by dividing a packet size of the second transfer Packet by the predetermined length when storing the second transfer packet into the predetermined data unit, and a sum of the first packet count and the second packet count is less than or equal to the predetermined number.
