ZR36504 -
Full Video and Audio Interface solution for Video via USB
The ZR36504 is an ideal solution for digital camera manufacturers who want to utilize the Universal
Serial Bus as an interface between the camera and the computer. Using a proprietary video compression
algorithm, the ZR36504 enables a throughput of up to 30f/s for CIF size images and up to 15f/s for VGA
size images, utilizing only half of total available bandwidth of the USB port. An appropriate software
driver in the host computer de-compresses the incoming USB data, consuming only 25% of CPU time
(@ CIF 30f/s). The resulting digital image quality is almost identical to the source coming from the
camera. This monolithic feature of the ZR36504 makes it ideal to be used as a one chip solution for a
very low cost USB portable Video Camera.
The ZR36504 can also be used to transfer video sequence from a Composite-Video source to the
computer for editing (this requires an additional video decoder chip). Due to the fact that the USB
bandwidth used by the ZR36504 can be adjusted (0.5-7.5 Mbit/sec), the video software application
always has enough time to record the incoming compressed video data on disk and display full frame-
rate on screen simultaneously.
The ZR36504 is compatible with the NT1003-1, but has a smaller package. It supports simultaneous
Serial Digital Audio input and simultaneous external Bulk-Data input as well, and eliminates the need for
an external EEPROM to set a specific manufacturer USB ID code. The ZR36504 also supports 16 Mbit
DRAMs for a better quality VGA video and still capture.
