Abstract:

This paper shows model of DVB-T receiver intended to test capabilities for watching and recording of live TV based on Raspberry Pi. The Raspberry Pi (RPI) is a single-board computer.The design is based on a Broadcom BCM2835 system on a chip (SoC), which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 512 megabytes of RAM. Operating system is based on Debian Linux adopted for RPI called Raspbian. For DVB-T receiver is used "RTL2832U+R820T DVB-T SDR+DAB+FM USB 2.0 DIGITAL TV" Tuner connected to USB port of RPI. The RTL2832U is a high-performance DVB-T COFDM demodulator that supports a USB 2.0 interface. The RTL2832U complies with NorDig Unified 1.0.3, D-Book 5.0, and EN300 744 (ETSI Specification). It supports 2K or 8K mode with 6, 7, and 8MHz bandwidth. Modulation parameters, e.g., code rate, and guard interval, are automatically detected. For Personal Video Recorder (PVR) implementation are used two software packets: Tvheadend and Video Disk Recorder. Tvheadend is a TV streaming server for Linux supporting DVB-S, DVB-S2, DVB-C, DVB-T, ATSC, IPTV, and Analog video (V4L) as input sources and can be used as a PVR backend of XBMC. The Video Disk Recorder (VDR) is a free, non-commercial project to create a digital video recorder. It is possible to receive, record and playback digital TV broadcasts compatible with the DVB standard.
