Abstract

Apparatus, including a host processor, which is configured to receive video data encapsulated in a standard definition transmission format, and to store the encapsulated video data in a memory. The apparatus further includes a data converter, which is configured to receive high definition video data as a sequence of packets and to encapsulate the sequence of packets in the standard definition transmission format. The data converter is also configured to convey the encapsulated packets to the host processor so that the host processor stores the packets in the memory.

Claims

1. Apparatus, comprising:

a host processor, which is configured to receive video data encapsulated in a standard definition transmission format, and to store the encapsulated video data in a memory; and

a data converter, which is configured;

to receive high definition video data as a sequence of packets,

to encapsulate the sequence of packets in the standard definition transmission format, and

to convey the encapsulated packets to the host processor so that the host processor stores the packets in the memory.

2. The apparatus according to claim 1, wherein the high definition video data comprises compressed high definition video data.

3. The apparatus according to claim 2 wherein the compressed high definition video data is compressed using at least one of spatial redundancy and temporal redundancy.

4. The apparatus according to claim 1, wherein the packets within the sequence are equally sized.

5. The apparatus according to claim 1, wherein the data converter is configured to select a number of packets for encapsulation to be a largest integral number of packets able to fit into a line of the standard definition transmission format.

6. The apparatus according to claim 1, wherein the data converter is configured to receive the encapsulated packets in the standard definition transmission format from the host processor, to extract the sequence of packets from the encapsulated packets, and to transmit the sequence of packets as high definition video data.

7. The apparatus according to claim 6, wherein the high definition video data comprises compressed high definition video data.

8. The apparatus according to claim 1, and further comprising a codec which is configured to compress the high definition video data as the sequence of packets, and to convert the sequence of packets to video data in a high definition transmission format.

9. The apparatus according to claim 8, wherein the codec is configured to receive the sequence of packets from the data converter, and to convert the sequence of packets to video data in a high definition transmission format suitable for a screen displaying high definition video.

10. The apparatus according to claim 1, wherein the standard definition transmission format comprises a preset number of lines of data, and wherein each line of data comprises a predetermined number of pixels.

11. A method, comprising:

configuring a host processor to receive video data encapsulated in a standard definition transmission format, and to store the encapsulated video data in a memory; and

configuring a data converter;

to receive high definition video data as a sequence of packets,

to encapsulate the sequence of packets in the standard definition transmission format, and

to convey the encapsulated packets to the host processor so that the host processor stores the packets in the memory.

12. The method according to claim 11, wherein the high definition video data comprises compressed high definition video data.

13. The method according to claim 12, wherein the compressed high definition video data is compressed using at least one of spatial redundancy and temporal redundancy.

14. The method according to claim 11, wherein the packets within the sequence are equally sized.

15. The method according to claim 11, wherein the data converter is configured to select a number of packets for encapsulation to be a largest integral number of packets able to fit into a line of the standard definition transmission format.

16. The method according to claim 11, wherein the data converter is configured to receive the encapsulated packets in the standard definition transmission format from the host processor, to extract the sequence of packets from the encapsulated packets, and to transmit the sequence of packets as high definition video data.

17. The method according to claim 11, and further comprising configuring a codec to compress the high definition video data as the sequence of packets, and to convert the sequence of packets to video data in a high definition transmission format.

18. The method according to claim 17, wherein the codec is configured to receive the sequence of packets from the data converter, and to convert the sequence of packets to video data in a high definition transmission format suitable for a screen displaying high definition video.

19. The method according to claim 16, wherein the high definition video data comprises compressed high definition video data.

20. The method according to claim 11, wherein the standard definition transmission format comprises a preset number of lines of data, and wherein each line of data comprises a predetermined number of pixels.

21. Apparatus, comprising:

an endoscope comprising a high definition video camera;

a host processor, which is configured to receive video data encapsulated in a standard definition transmission format, and to store the encapsulated video data in a memory; and

a data converter, which is configured;

to receive high definition video data originating from an image captured by the high definition video camera as a sequence of packets,

to encapsulate the sequence of packets in the standard definition transmission format, and

to convey the encapsulated packets to the host processor so that the host processor stores the packets in the memory.

22. A method, comprising:

incorporating a high definition video camera into an endoscope;

configuring a host processor to receive video data encapsulated in a standard definition transmission format, and to store the encapsulated video data in a memory; and

configuring a data converter;

to receive high definition video data originating from an image captured by the high definition video camera as a sequence of packets,

to encapsulate the sequence of packets in the standard definition transmission format, and

to convey the encapsulated packets to the host processor so that the host processor stores the packets in the memory.
