The efficiency of digital video and audio transmission is basically depending on the used compression methods, therefore continuous development of these processes is expected. Currently for digital transmission the MPEG-2 and H.264 (MPEG-4 Part 10 AVC) procedures are widely used. CableWorld’s new generation decoder family automatically detects and decodes streams of both standards. Nowadays in addition to the increasing number of programs, the improved picture and sound quality is a fundamental requirement as well. Therefore, the providers’ offer broadens with more HD quality programs. According to this tendency our decoders are also capable of processing high-resolution images.
The input streams may come over IP or ASI network. According to the needs the various versions of decoders can also be ordered with CI (Common Interface) units.
The decoders possess a variety of digital (HDMI, HD-SDI) and analog (YPrPb, CVBS) outputs. The HD programs are simultaneously available in SD format (optionally in PAL, in SECAM or in NTSC). The selection of the wished program to be decoded can be done according to the Service ID or to the video and audio PID.
