forecast & imagine: Chips for set-top-box in future

The main chipset for Set-Top Box (player):
The main chipset for Set-Top Box is basically the same as low-grade tabletpc chipset scheme.But increase some functions

Some display functions different as low-grade tabletpc chipset:
All support HDMI output (Support HDCP)(All of support HDMI 1.4)
Support one DVI output
All have a video DAC in the main chip, can support YCbCr and CVBS-video output

DSP unit (the different as low-grade tabletpc chip):
Have all the functions as the low-grade tabletpc chip scheme. And increase these functions:
All support H.264,MPEG4(support to DivX 6 & Xvid),VC-1,WMV9,MPEG2,MPEG1 decode by hardware,all of these formats can support to 1920*1080 30fps max.
Some more high-grade chips support these formats up to 2160P or higher (But MPEG2 still support 1080I or 720P max)(support 3D video) decoding by hardware.
All support M2TS(blue-ray),MP4,MKV,DivX,WebM,OGM,MTS,F4V,FLV,WMV,ASF,AVI,MOV,3GP,TS(TP),VOB,MPEG(mpg,dat) etc. video container
All support AAC(HE-AAC), WMA, MPEG2 layer 1 & 2 audio, AC3 (two channel only) audio decoding by hardware
Some of support RM/RMVB decoding by hardware
Some more high-grade chips support DTS,DVD-audio,MLP,Ture-HD,DTS-HD,WMA-HD,ALAC etc. decoding by hardware, some of support decoding multichannel these audio format by hardware.
Some more high-grade chips support DSD audio (also support SACD (Super Audio Disc))
Some of support H.264 encoding by hardware

Other different as the low-grade tabletpc chipset scheme:
Support 3* TS Stream input port (Can support DVB-SH,DVB-T,DMB-TH,ISDB-T,DVB-C,DVB-S,DVB-S2 etc. digital TV demodulation chipset)
If the DSP unit support DSD audio and SACD, so the audio DAC support DSD playback

More high-grade main chips (for set-top-box), not only the CPU and GPU's performance more higher (have double or multi-core CPU),and the DSP unit support more kinds video and audio decoding by hardware
