High data rate interface apparatus and method
A data interface for transferring digital data between a host and a client over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control and presentation data. The signal protocol is used by link controllers configured to generate, transmit, and receive packets forming the communications protocol, and to form digital data into one or more types of data packets, with at least one residing in the host device and being coupled to the client through the communications path. The interface provides a cost-effective, low power, bi-directional, high-speed data transfer mechanism over a short-range “serial” type data link, which lends itself to implementation with miniature connectors and thin flexible cables which are especially useful in connecting display elements such as wearable micro-displays to portable computers and wireless communication devices.
1. A method for routing pixel data from a scaled video stream packet within a client in a mobile display digital interface (MDDI) communication system, the method comprising the steps of:
receiving a predefined pixel content by the client from a host;
scaling the predefined pixel content to a specific size by the client;
providing a data attribute field with values that specify pixel data routing and display buffer locations;
sending the scaled pixel content to at least one specific display buffer location of the display buffers locations within the client; and
displaying the scaled pixel content in the at least one specific display buffer location.
2. The method of claim 1 wherein the at least one specific display buffer location includes an image displayed to the left eye or the right eye.
3. The method of claim 1 wherein the at least one specific display buffer location is read by a display controller to refresh the image currently being displayed.
4. The method of claim 1 wherein the at least one specific display buffer location comprises an offline image buffer.
5. A hardware system for routing pixel data from a scaled video stream packet within a client in a mobile display digital interface (MDDI) communication system, the system comprising:
means for receiving a predefined pixel content by the client from a host;
means for scaling the predefined pixel content to a specific size by the client;
means for providing a data attribute field with values that specify pixel data routing and display buffer locations;
means for sending the scaled pixel content to at least one specific display buffer location of the display buffer locations within the client; and
means for displaying the scaled pixel content in the at least one specific display buffer location.
6. The system of claim 5 wherein the at least one specific display buffer location contains an image displayed to the left eye or the right eye.
7. The system of claim 5 further comprising a means for reading the at least one specific display buffer location to refresh the image currently being displayed.
8. The system of claim 5 wherein the at least one specific display buffer location comprises an offline image buffer.
9. A computer readable medium comprising program instructions which are executed by a processor to implement pixel data to be routed from a scaled video stream packet within a client in a mobile display digital interface (MDDI) communication system, the computer readable medium comprising:
program instructions that cause a predefined pixel content be received by the client from a host;
program instructions that cause the predefined pixel content be scaled to a specific size by the client;
program instructions that cause a data attribute field to be provided with values that specify pixel data routing and display buffer locations;
program instructions that cause the scaled pixel content be sent to at least one specific display buffer location, of the display buffers locations, within the client; and
program instructions that cause the scaled pixel content in the at least one specific display buffer location be displayed.
10. The of claim 9 wherein the computer readable medium of claim 9 wherein at least one specific display buffer location contains an image displayed to the left eye or the right eye.
11. The computer readable medium of claim 9 further comprising code for causing an instruction to read at least one specific display buffer location to refresh the image currently being displayed.
12. The computer readable medium of claim 9 wherein the at least one specific display buffer location comprises an offline image buffer.
13. A hardware system for routing pixel data from a scaled video stream packet within a client in a mobile display digital interface (MDDI) communication system, the system comprising:
a client configured to:
receive a predefined pixel content from a host;
scale the predefined pixel content to a specific size;
receive a provided data attribute field with values that specify pixel data routing and display buffer locations;
send the scaled pixel content to at least one specific display buffer location of the display buffer locations within the client; and
display the scaled pixel content in the at least one specific display buffer location.
14. The system of claim 13 wherein the client is further configured to read the at least one specific display buffer location to refresh the image currently being displayed.
