GS1661A
The GS1661A is a multi-rate SDI integrated Receiver which includes complete SMPTE processing, as per SMPTE 292M and SMPTE 259M-C. The SMPTE processing features can be bypassed to support signals with other coding schemes.
The GS1661A integrates Gennum's next-generation state-of-the-art adaptive cable equalizer technology, achieving unprecedented cable lengths and jitter tolerance. It features DC restoration to compensate for the DC content of SMPTE pathological signals.
The device features an Integrated Reclocker with an internal VCO and a wide Input Jitter Tolerance (IJT) of 0.7UI.
A serial digital loop through output is provided, which can be configured to output either reclocked or non-reclocked serial digital data. The Serial Digital Output can be connected to an external Cable Driver.
The device operates in one of four basic modes: SMPTE mode, DVB-ASI mode, Data-Through mode or Standby mode.
In SMPTE mode, the GS1661A performs SMPTE de-scrambling and NRZI to NRZ decoding and word alignment. Line-based CRC errors, line number errors, TRS errors and ancillary data check sum errors can all be detected. The GS1661A also provides ancillary data extraction. The entire ancillary data packet is extracted, and written to host-accessible registers. Other processing functions include H:V:F timing extraction, Luma and Chroma ancillary data indication, video standard detection, and SMPTE 352M packet detection and decoding. All of the processing features are optional, and may be enabled or disabled via the Host Interface.
In DVB-ASI mode, 8b/10b decoding is applied to the received data stream.
In Data-Through mode, all forms of SMPTE and DVB-ASI decoding are disabled, and the device can be used as a simple serial to parallel converter.

スタジアムの巨大スクリーンで野球の試合のアクションのリプレイを視聴する場合でも、大画面テレビで映画を視聴する場合でも、ノートパソコンでビデオをストリーミングする場合でも、高品質のオーディオビジュアル (AV) 体験が常に期待されています。デジタルAV伝送には、超高精細シリアルデジタルインターフェイス (UHD-SDI) と高解像度マルチメディアインターフェイス (HDMI) の2つの規格があります。UHD-SDIは、同軸または光ファイバーケーブルを介した非圧縮・非暗号化のデジタルAV信号の伝送を標準化します。HDMI は、HDMI準拠のソースからAVディスプレイに高解像度、高速デジタルマルチトラックオーディオおよび非圧縮ビデオ信号を送信するためのデジタルインターフェイスです。どちらも超高精細AV信号をソースからディスプレイに転送できますが、コンピューター、ゲーム機、Blu-ray/DVDプレーヤー、テレビ、プロジェクターなどの消費者向け機器の接続にはHDMIが好まれます。UHD-SDIは、ケーブル両端の物理的なロック機構で長距離伝送と堅牢な接続をサポートするため、プロの屋内/屋外ビデオ制作やテレビ放送などのハイエンドアプリケーションに適しています。UHD-SDI同軸ケーブルは最大300フィートの信号を転送できますが、HDMIケーブルは50フィート以内でも過度の信号劣化が問題となります。これら2つのインターフェイスは、HDMI-SDIまたはSDI-HDMIコンバーターを使って併用できます。例えば、図1のように、HDMIディスプレイはSDIストリームの信頼性監視に使用でき、この場合、特別に調整されたSDI固有のディスプレイを使用する必要がなくなります。

今すぐ読むI designed my first product using the Serial Digital Interface (SDI) back in 1996, and little did I know that this fledgling coax-based video interface standard would dominate my career for the next 20+ years. Back then, SDI was limited to carrying Standard Definition (SD) digital video at 270 Megabits per second (Mbps), but would evolve to higher and higher data rates to carry High Definition 720p, 1080i and 1080p, and most recently 4K Ultra High Definition (UHD) video, at cable lengths that were not thought possible. The convenience of a low cost single conductor coaxial copper cable, capable of carrying 4K video up to 100m has meant that SDI has become the de facto AV connectivity of choice in markets such as broadcast, Pro AV, medical and surveillance.
