PBI DCH-5300P AVS+高端数字信号综合处理器 (AVS+/直播星)

DCH-5300P is an integrated AVS+ receiving and decoding processor that complies with the GY/T 257.1-2012 "Advanced Audio and Video Coding for Radio and Television - Part 1: Video" AVS+ industry standard. It is also compatible with MPEG-2 (MP@ML & MP@HL), MPEG-4 AVC/H.264, and H.265/HEVC standards, supporting decoding of high-definition and standard-definition video formats as well as DRA digital audio decoding. Employing CI universal descrambling technology and dual PCMCIA interfaces, it supports multiple conditional access systems worldwide, allowing reception of various encrypted digital television signals through the replacement of different PCMCIA modules.

The DCH-5300P offers a wide range of interfaces, supporting DVB-S2/C/T/DTMB/ABS-S tuner inputs, ASI inputs, and TS/IP inputs. After demodulation and descrambling, signals pass through its built-in remultiplexer module, enabling flexible remultiplexing of multiple input streams to regenerate single or multiple program streams, which are then output to backend devices via ASI and IP. The DCH-5300P supports high-definition and standard-definition video decoding and digital audio decoding, featuring CVBS and balanced audio output interfaces for analog audio and video signals, as well as SDI, HDMI digital audio and video interfaces, and AES/EBU digital audio interfaces.

The DCH-5300P incorporates two transcoding interfaces, which can be upgraded to a DCH-5300PE receiver-transcoder combo by adding a transcoding module. The AVS+ signal is transcoded to H.264 format high-definition and standard-definition digital video signals, which can be passed through directly or processed by the remultiplexer module before being output via ASI and IP.

The DCH-5300P/DCH-5300PE are professional-grade high-definition digital television signal receivers and receiver-transcoder combos designed specifically for content providers, broadcasters, and operators of cable, terrestrial, and IPTV new media. They can be widely applied in various digital television networks to meet the customized needs of operators at all levels.
