Digital data interface device
First Claim
1. A digital data interface device for transferring digital presentation data at a high rate over a communication link, comprising:
- a message interpreter module that receives commands from and generates response messages through the communication link to a system controller, interprets the messages, and routes the information content of the commands to an appropriate module within the digital data interface device;
a content module that receives data from a peripheral device, stores the data and transfers the data to the system controller through the communication link; and
a control module that receives information from the message interpreter, and routes information to a control block of the peripheral device.

Abstract
The present invention is directed a digital data interface device for transferring digital presentation data at a high rate over a communication link. The digital data interface device includes a message interpreter, content module and a control module. The digital data interface device may include an MDDI link controller. The digital data interface device can be used to control a peripheral device, such as a camera, bar code reader, image scanner, audio device or other sensor. In one example, a cellular telephone having a camera with an MDDI link and a digital data device interface is provided.

23. A Mobile Display Digital Interface (MDDI) Camera Interface Device, comprising:
-
a camera message interpreter (CMI) for receiving commands from and generating response messages through an MDDI Host to a master controller, interpreting the messages, and routing the information content to the appropriate block within the camera interface device;
a camera video interface block (VFE) receiving image data from the camera, storing the image data and transferring the image data to the MDDI Host through an image data interface; and
a camera control block (CCB) for receiving information from the CMI, and routing the information to various control blocks of the camera and camera peripherals.
