Abstract

A transmitting device, a receiving device, and a method for transmitting and a method for receiving data streams, in particular video streams, are described. The transmitting device for data streams, in particular video data, has at least one unit. This at least one unit is designed for subdividing the data streams into sections, the sections into packets, and for providing the sections in a sequence that is the reverse of an original sequence and the packets in an original sequence.

Claims

1. A transmitting device for transmitting data streams, comprising:

at least one unit having;

a subdividing arrangement to subdivide the data streams into sections and to subdivide the sections into packets; and

an arrangement to provide these sections in a sequence that is the reverse of an original sequence and the packets in an original sequence.

2. The transmitting device of claim 1, wherein the at least one unit includes:

a memory device;

a packet assembling device; and

a transmitting module;

wherein;

video data is storable in the memory unit,

the packet assembling device is operable to subdivide the video data into sections and to subdivide the sections into packets, and

the transmitting module is operable to transmit the sections in a sequence that is the reverse of an original sequence and to transmit the packets in an original sequence.

3. The transmitting device of claim 2, further comprising:

an additional unit to assign an index characterizing a sequence to each packet, wherein the transmitting module is operable to transmit a corresponding index with each packet.

4. The transmitting device of claim 1, wherein the transmitting device is integrated into a video monitoring system.

17. The transmitting device of claim 1, wherein the data streams include video data.

5. A receiving device for receiving data streams, comprising:

at least one module, wherein received data streams are subdivided into sections and in which the sections are subdivided into packets, the sections have a sequence which is the reverse of an original sequence, and the packets have an original sequence, and wherein the at least one module is operable to provide images of one of the sections in a reverse sequence.

6. The receiving device of claim 5, wherein the at least one module includes:

a receiving module;

a decoder;

an image buffer; and

a display module;

wherein;

the receiving module is operable to receive video data,

the decoder is operable to decode the video data,

the image buffer is operable to store images of one of the sections, and

the display module is operable to display the images in a reverse sequence.

7. The receiving device of claim 5, further comprising:

a detection unit to process one of the sections, and to compare an index of one of the packets with another index of one of the packets of a previous one of the sections.

8. The receiving device of claim 5, wherein the receiving device is integrated into a video monitoring system.

18. The receiving device of claim 5, wherein the data streams include video data.

9. A method for transmitting data streams, the method comprising:

subdividing the data streams into sections and the sections into packets; and

providing the sections in a sequence that is the reverse of an original sequence and the packets in an original sequence.

10. The method of claim 9, further comprising:

transmitting the provided sections and packets, wherein the data streams include compressed video data.

11. A method for receiving data streams, the method comprising:

subdividing received data streams into sections and the sections into packets, wherein the sections have a sequence which is the reverse of an original sequence, and the packets have an original sequence, and wherein the images of one of the sections are provided in a reverse sequence.

12. The method of claim 11, wherein video data are received and decoded, and wherein the images of one of the sections are stored and displayed in a reverse sequence.

13. A computer readable medium having a computer program executable by a processor, comprising:

program code for transmitting data streams by performing the following;

subdividing the data streams into sections and the sections into packets; and

providing the sections in a sequence that is the reverse of an original sequence and the packets in an original sequence.

14. The computer readable medium of claim 13, wherein the provided sections and packets are transmitted, and wherein the data streams include compressed video data.

15. A computer readable medium having a computer program executable by a processor, comprising:

program code for receiving data streams by performing the following;

subdividing received data streams into sections and the sections into packets, wherein the sections have a sequence which is the reverse of an original sequence, and the packets have an original sequence, and wherein the images of one of the sections are provided in a reverse sequence.

16. The computer readable medium of claim 15, wherein video data are received and decoded, and wherein the images of one of the sections are stored and displayed in a reverse sequence.
