Abstract

A data transmitter transmitting a data packet containing identifier information including a kind of data, a sequence of data, and/or a packet generating sequence. A receiver extracting a packet number and the identifier information for an error-receipt occurring data packet based upon the identifier information recorded in a header of the packet, generating retransmission control information, such as retransmission times and priority, based on the extracted packet number and the identifier information and transmitting the retransmission control information to the transmitter of the packet. The retransmitting the error-occurring data packet according to the received retransmission control information. The number of retransmissions and the retransmission priority can be varied according to characteristics of the transmitted data, so that retransmissions is suitable for the characteristics of the data and to more stably receive the data that is more influential to the restoration of the data.

Claims

1. A data transmitting system comprising:

a packet generating section;

a transmitting section; and

a receiving section,

wherein the packet generating section generates a data packet containing identifier information according to a kind of data, a sequence of data, and a packet generating order.

2. The data transmitting system according to claim 1, wherein the sequence of data is a chronological order in a same kind of sequentially generated data, and the identification information is generated in order for earlier data in the sequence of data to have more importance than later data in the sequence of data.

3. The data transmitting system according to claim 1, wherein the kind of data is one of inter image and intra image data.

4. The data transmitting system according to claim 3, wherein the sequence of data is a chronological order in sequentially generated inter image data, when the kind of data is inter image data.

5. The data transmitting system according to claim 3, wherein the identification information is generated such that the intra image data has more importance than the inter image data.
