Digital television data format conversion with automatic parity detection

A digital television data format converter, comprising:

• a digital television data format converter receiver block for receiving a serial digital television data stream and detecting whether parity data is in the serial digital television data stream;
• a digital television data format converter buffer for loading the serial digital television data stream from the digital television data format converter receiver block;
• and
• a digital television data format converter transmitter block for reading the serial digital television data stream out of the digital television data format converter buffer, transmitting a parallel digital television data stream converted from the serial digital television data stream in accordance with a first conversion protocol if the serial digital television data stream is a parity data stream, and transmitting a parallel digital television data stream converted from the serial digital television data stream in accordance with a second conversion protocol if the serial digital television data stream is a non-parity data stream.
