QAMi5107 Low-cost QAM demodulator and MPEG-2 decoder SOC for set-top boxes
The QAMi5107 provides an integrated demodulator/decoder solution for digital cable receivers for compressed video, sound and data services. A QAM (quadrature amplitude modulation) demodulator and FEC performs IF to MPEG-2 block processing of QAM carriers. The demodulated stream is then processed by video and audio decoders.
The device implements a fully unified SDR SDRAM based memory architecture that integrates the Omega2 video decoder cell together with a blitter engine and a multichannel DMA controller to provide enhanced performance for graphics and real-time stream transfers. Transfer of data such as pixmaps, audio streams, stills and PES can be performed efficiently using the QAMi5107 DMA.
A true-color mode provides OSD graphics allowing the display of RGB16 formats: RGB565, ARGB1555 and ARGB4444. This directly supports up to 65,536 colors in a region. Alpha blending by region or by pixel is available for mixing with video and background layers. The above feature set, guarantees a smooth user interface and high performance for demanding middlewares such as MHP™.
The QAMi5107 is the first single chip cable STB IC to combine a very low cost solution with advanced security features. DVB and ICAM descramblers together with a smart card interface ensure that all the major conditional access systems can be supported.
