A high definition television player records and plays back HDTV signals in a closed circuit to demonstrate high definition television. The signals are recorded on a hard drive, CD, DVD or the like in discrete 2-meg data blocks, with each block of data being separately identified. The invention provides for continuous looping play of a desired program or programs by identifying the starting data block and ending data block of the program. The program play is begun at the starting block. When the program is finished at the end block, play continues at the start block, and so on until the stop button is pushed.
