MSVD-HD

IP Product Brief Applications • Set-top boxes MSVD-HD Multi-Standard High-Definition Video Decoder (H.264, VC-1, MPEG-1/2) The Multi-Standard High-Definition Video Decoder DesignObject™ (MSVD-HD*) is one of the smallest synthesizable cores in the market, performing time multiplexed decoding of multiple streams in different standards at all resolutions up to 2048x2048 pixels. It is substantially smaller than a fully programmable solution. The MSVD-HD is a real-time solution for dual-stream high-definition video decoding with a single core at a low clock rate. • Digital TV sets and IPTV applications • DVD, HD-DVD and Blu-ray players and recorders • Portable multimedia players • Surveillance Key Features • Supports H.264, MPEG-1/2 & VC-1 up to 1080p @ 60 fps • Supports all DVB, ATSC, HDTV, DVD, VCD resolutions • Supports picture size from 48x32 to 2048x2048 pixel The MSVD-HD currently supports H.264, MPEG-1/2 and VC-1 standards. The decoding functionality is implemented as an autonomously working pipeline consisting of various hardware blocks. The driver software running on an external controller, a general purpose 32bit processor, performs setup and general controlling tasks. The MSVD-HD reads the input stream from a buffer located in the system memory (SDRAM) and generates decoded video in YCbCr 4:2:0 format. The output pictures are stored in the decoded picture buffer area within the system memory. MSVD-HD is an optimized solution for video decoding applications, based on an architecture that implements pipelining and parallelism on different levels. MSVD-HD consists of a software part and a hardware part. The hardware part is composed of two main blocks, the Stream Interpreter and the Multi-standard Video Decoding Engine. In order to achieve maximum performance, the two blocks work in parallel. The MSVD-HD is optimized to satisfy a wide range of applications and technologies with optimal performance at low silicon cost. Its interfaces are designed for easy integration into system-on-chip designs. *MSVD-HD was formerly part of the sci-worx GmbH product portfolio. Silicon Image acquired sciworx in January 2007.
