About two-dimensional parity check

[desk...@gmail.com]

我想知道 two-dimensional parity check 每隔幾行(幾組bytes) 傳一組 column parity? 這是誰跟誰在那裡訂的?

請問是 sender & receiver 自己訂還是有甚麼協定?

補充: 我發現二維 parity題目或範例給的行數(高度)常不一樣。我想問說是有特定幾組 bytes就加一組 parity bytes，還是說一個封包一組 parity bytes?

[Prof. Hsiao]

Error bit is added in every single row and every single column.

Sender and receiver should decide to use even parity or odd parity before they start to exchange message.

The length of row and column is chosen by the sender and the receiver as well.
