Data processing apparatus for configuring camera interface based on compression characteristic of compressed multimedia data and related data processing method

Abstract

A data processing apparatus includes: an output interface, arranged for packing a compressed multimedia data into an output bitstream and outputting the output bitstream via a camera interface; and a camera controller, arranged for referring to at least a compression characteristic of the compressed multimedia data to configure a transmission setting of the output interface over the camera interface. The transmission setting of the output interface includes a number of data lines enabled over the camera interface or includes a behavior of the output interface during a blanking period between adjacent data transmissions.

         1 . A data processing apparatus comprising:
 an output interface, arranged for packing a compressed multimedia data into an output bitstream and outputting the output bitstream via a camera interface; and   a camera controller, arranged for referring to at least a compression characteristic of the compressed multimedia data to configure a transmission setting of the output interface over the camera interface;   wherein the transmission setting of the output interface comprises a number of data lines enabled over the camera interface or comprises a behavior of the output interface during a blanking period between adjacent data transmissions.   
     
     
         2 . The data processing apparatus of  claim 1 , wherein when the transmission setting of the output interface comprises a number of data lines enabled over the camera interface, an operating frequency of each data line remains unchanged regardless of the configured number of data lines. 
     
     
         3 . The data processing apparatus of  claim 1 , wherein when the transmission setting of the output interface comprises a behavior of the output interface during a blanking period between data transmissions, a number of data lines enabled over the camera interface and an operating frequency of each data line remain unchanged regardless of the configured behavior of the output interface during the blanking period. 
     
     
         4 . A data processing apparatus comprising:
 an input interface, arranged for receiving an input bitstream via a camera interface, and un-packing the input bitstream into a compressed multimedia data that is transmitted over the camera interface; and   an image signal processor (ISP) controller, arranged for configuring a reception setting of the input interface over the camera interface in response to at least a compression characteristic of the compressed multimedia data;   wherein the reception setting of the input interface comprises a number of data lines enabled over the camera interface or comprises a behavior of the input interface during a blanking period between adjacent data transmissions.   
     
     
         5 . The data processing apparatus of  claim 4 , wherein when the transmission setting of the output interface comprises a number of data lines enabled over the camera interface, an operating frequency of each data line remains unchanged regardless of the configured number of data lines. 
     
     
         6 . The data processing apparatus of  claim 4 , wherein when the reception setting of the input interface comprises a behavior of the input interface during a blanking period between adjacent data transmissions, a number of data lines enabled over the camera interface and an operating frequency of each data line remain unchanged regardless of the configured behavior of the input interface during the blanking period. 
     
     
         7 . A data processing method comprising:
 referring to at least a compression characteristic of a compressed multimedia data to configure a transmission setting of an output interface over the camera interface; and   utilizing an output interface for packing the compressed multimedia data into an output bitstream and outputting the output bitstream via the camera interface;   wherein the transmission setting of the output interface comprises a number of data lines enabled over the camera interface or comprises a behavior of the output interface during a blanking period between adjacent data transmissions.   
     
     
         8 . A data processing method comprising:
 configuring a reception setting of an input interface over a camera interface in response to at least a compression characteristic of a compressed multimedia data; and   utilizing an input interface for receiving an input bitstream via the camera interface, and un-packing the input bitstream into the compressed multimedia data that is transmitted over the camera interface;   wherein the reception setting of the input interface comprises a number of data lines enabled over the camera interface or comprises a behavior of the input interface during a blanking period between adjacent data transmissions.
