摘要：DVB-H (Digital Video Broadcasting for Handheld terminals) is a digital transmission standard developed by the international DVB-Project. It was standardized in 2004 and enables small battery powered handheld devices to receive IP data services such as low definition TV services. The DVB-H standard is derived from the DVB-T standard which is used to broadcast TV services in Europe. The convolution code is used as error correction code. In this paper, we have implemented physical layer of DVB-H for 4K mode system. Here we had transmitted a JPEG format of frame of movie through AWGN channel and observed the image quality for different code rates used for convolution coding. The code rates used are 1/2, 2/3, 3/4, 5/6 and 7/8
