Patent ID: 8390664

Claim:
A hand-held electrical communication device, comprising: an image sensing unit used for generating an original image frame; a mobile TV receiver used for receiving a compressed video data; an image signal processing unit used for adjusting the original image frame into an adjusted image frame or decompressing the compressed video data into a video image frame, and scaling the adjusted image frame or the video image frame into a scaled image frame; a display unit; a baseband processing unit used for displaying the scaled image frame on the display unit; a first bus; and a second bus, wherein the mobile TV receiver outputs the compressed video data to the image signal processing unit via the first bus, and the image signal processing unit outputs the scaled image frame to the baseband processing unit via the second bus; the mobile TV receiver is further used for receiving a compressed audio data, the image signal processing unit decompresses the compressed audio data into an audio signal and outputs the audio signal to the baseband processing unit via an inter-IC sound (I2S) bus, and the baseband processing unit outputs the audio signal to an audio device; the image signal processing unit includes: a TV receiver interface used for receiving the compressed video data from the mobile TV receiver and the compressed audio data from the mobile TV receiver; a video decoder used for decompressing the compressed video data into the video image frame; an audio decoder used for decompressing the compressed audio data into the audio signal; and an inter-IC sound transmitter used for outputting the audio signal to the baseband processing unit.
