Abstract

An embodiment of the invention includes a protocol to send image and user data across a single connection. A second embodiment includes a protocol which can send image and GPS (Global Positioning System) data across a single connection. The protocol is used for assembling data packets that include imaging data, user centric information and optional GPS data. The protocol defines two packet formats that can be differentiated by the packets header. The first packet format contains lengths for the image header, session, creator and transmission time. The body contains the image header that describes the length of the image data and is followed by the image data. This is then followed by blobs (Binary Large Objects) that describe user specific information and the transmission time of the packet. The second packet format has the addition of header fields that describe the length of the GPS data blobs. The two packet formats are completely interchangeable in an application and can be used to minimise the amount of data being transferred over a network and reduce the amount of time it takes to send user centric imaging data.

Description

Protocol for packetizing image data into a self-describing binary large object This invention relates to the protocol for transferring image and related data in a packetized format.

Background

Transferring related data over a network can incur performance penalties that impact time sensitive applications. This is typically because of the need to initiate multiple requests to send related data attributes, thus incurring time penalties with setting up and tearing down a connection on top of the actual time it takes to send data. This can impede the user experience by introducing lag when streaming a series of images. It can also produce code that is both overly complicated and costly to maintain.

Statement of Invention

To overcome these problems the present invention proposes a data protocol that operates at the Application layer of the OSI model. The protocol packetizes related data into a self-describing binary large object (blob).

The protocol supports two data formats; the first containing the image data, information that identifies the session, the creator of the image and the time in which the image was transmitted.

The second format has the addition of GPS data associated with the image.

Figure 1 shows the first packet format that the protocol supports.

Figure 2 shows the second packet format that the protocol supports.

Both packet formats are made up of a header and body. In the first format the header describes the type of packet in use and data lengths for the image header length, the session, creator and transmission time. The body contains a data blob describing the length of the image data followed by the image data. This is followed by blobs of encoded data that describe the session, creator and transmission time.

In the second format the header describes the type of packet in use. This is followed by the length of the data blobs that describe header lengths of the image, latitude, longitude, altitude, session, creator and transmission time. The body contains encoded data blobs that describe the lengths of the image data, latitude, longitude and altitude. It also contains encoded data blobs that describe the session, creator and transmission time.

Detailed Description

The protocol will now be described by way of example and with reference to the accompanying drawings in which: Figure 3 shows an example of the first packet format being used to send image data together with information relating to the creator, session and transmission time.

Figure 4 shows an example of the second packet format being used to send image data, GPS data and information relating to the creator, session and the transmission time.

In figure 3 the packet contains a header and body totalling 409632 bytes that can be sent over a single HTTP connection.

In this example the header is made up of 0, 1, 1, 1, 2'.

The 0' represents which packet format is being used. The 1' shows the size of the blob that describes the length of the image. The next two numbers show the lengths of the blobs that describe the session in use and the creator of the image. The last remaining number 2', is the size of the blob that represents the timestamp of the packet.

The body in the example is made up from 6, 409600, 2, 5, 13'.

The 6' is the length of the following image data blob of 409600'. The session and creator lengths in the header correspond to the 2' and 5' which show the number of bytes that make up the value of the field. The same principle applies to the time stamp which has a blob of 13 bytes that make up

the fields value.

In Figure 4 the packet contains and header and body totalling 409690 bytes. In addition to the previous packet format it contains header lengths of 2 bytes for Latitude, Longitude and Altitude.

These relate to the Latitude, Longitude and Altitude headers in the packets body, each of which in this example is 2 bytes. These two byte data blobs can be used to read the related fields value.

Claims (7)

  1. Claims 1. The protocol can send image and user data across a single connection.
  2. 2. The protocol can send image and GPS data across a single connection.
  3. 3. The protocol can be used with to transmit data over protocols such as HTTP or Sockets.
  4. 4. The protocol creates a self-describing blob which allows the receiver to read the header and determine the size and order of the data blobs in the body.
  5. 5. The protocol reduces the data traffic on a network by creating encapsulated data structures.
  6. 6. The protocol reduces the delay in sending a series of images.
  7. 7. The packet formats are interchangeable and can be used side by side in an application to reduce the overall network traffic.
