Question and Answer: 802.11n

transmission rate. in addition, 802.11n allows use of wider 40 MHz channels to double the bandwidth as compared to the legacy 20 MHz operation. 802.11n uses frame aggregation and block acknowledgements for improving the throughput efficiency.

[VNC] ycrcb-YUV-RGB

I. Introduction YUV (also known as ycrcb) is a color encoding method used by European television systems (PAL ). YUV is mainly used to optimize the transmission of color video signals, so that it is backward compatible with vintage black and white TVs. Compared with RGB video signal transmission, RGB requires three independent video signals to be transmitted at the same time ). "Y" indicates the brightness (Lumina nce or Luma), that is, the grayscale value. It is a baseband signal. "U" and "V" r

Basic concepts of pitemidlist in Delphi Deep Exploration

by titemidlist in Delphi. Because IDL mainly operates through pointers, pidl is usually used, which is defined as pitemidlist in Delphi. Pidl is a general method for determining the unique element in the shell namespace. All these Delphi data structures are defined in the shlobj unit. Different from the path of a DOS-style string type, pidl is binary data, and tshitemid and titemidlist are variable-length data types. The tshitemid is defined as follows: Tshitemid = packed recordCB: word; // rec
