FEATURES
General features● Integrated MPEG AVGD decoder: audio, video and graphics decoding and digital video encoding
● 5 planes display chain: background colour, background plane, MPEG display plane, graphics plane and cursor plane
● 16-Mbit or 32-Mbit external Synchronous DRAM (SDRAM) for MPEG audio and video decoding and graphics data storage
● Single or double external SDRAM organized as 1 M × 16 or 2 × 1 M × 16 (two independent 16-bit data bus) interfacing at 81 MHz. Due to efficient memory use in MPEG decoding, more than 1 Mbit is available for graphics in the single SDRAM configuration whereas 17 Mbits are available in the double SDRAM configuration.
● All basic operations of the AVGD decoder are possible in both 16- and 32-Mbit configuration; enhanced performance is achieved by the use of 32-Mbit external SDRAM
● Targeted to BSkyB 3.0 and Canal+ basic box and web box specifications
● Fast 16-bit data + 22-bit address synchronous or asynchronous interface with external control...
