DOCUMENTATION ROADMAP
=====================

This file contains the following sections:

NAMING RULE      Files named rules

CODE STRUCTURE   General description files structure in psb_video



NAMING RULE
=====================
This part describes general rule for naming added files in future.
Name Fomat: xx_xxxx.c/h

Explanation:
xx: represents the platform, such as psb for MRST, pnw for MFLD and tng for MRFLD.
xxxx: generally describes files function, such as cmdbuf for command buffer processing, H264ES for H264	encoding, H264 for H264 decoding. For encode codec, xxES is used.

The existed files may not be consistent with it completely. For the exsited files:
lnc_xxxx.c/h are files for encoding on MRST
psb_xxxx.c/h are files for decoding on MRST (some files are reused in MFLD)
pnw_xxxx.c/h are files for encoding/decoding on MFLD
tng_xxxx.c/h are files for encoding/decoding on MRFLD
xx_xxES.c/h are files for various encoding codec, others codec named are for various decoding codec
