DCH-5300P AVS Integrated Reception & Decoding Processor? ?Product Overview? The DCH-5300P is a professional-grade AVS integrated reception and decoding processor, compliant with the Chinese broadcasting industry standard GY/T 257.1-2012 (AVS ). It supports MPEG-2 (MP@ML & MP@HL), MPEG-4 AVC/H.264, H.265/HEVC video decoding, and DRA digital audio decoding, enabling high/standard-definition multi-format signal processing. Equipped with dual PCMCIA interfaces and CI descrambling technology, it decrypts signals from conditional access systems (e.g., Conax, NDS, Nagra, etc.) by swapping PCMCIA modules for satellite, cable, and terrestrial encrypted TV signals ?Key Features?
