HV-102J

全高畫質數位電視調變器

HD-SDI/HDMI 轉 ISDB-T/ISDB-Tb

50–950 MHz, 1200–1350 MHz

HV-102J 為全高畫質數位電視調變器,可將 HD-SDI 或 HDMI 影像源編碼為 H.264 或 MPEG2,並調變為 ISDB-T(ARIB STD-B31)或 ISDB-Tb(ABNT NBR 15601),透過同軸纜線或空中進行分送。任何符合標準的電視機或機上盒皆可直接接收,無需額外的轉接裝置。

04 · DVB-T 全高畫質調變器

特色

  • 01 低成本高畫質影像分配 — 相容於現有高畫質電視機,無需額外轉接裝置,接收機數量亦不受限制。分配器、放大器、接頭等周邊配件皆與一般電視所用者相同。
  • 02 多樣化影像輸入與格式 — 支援 VGA 與色差(YPbPr)影像輸入。除了 H.264/MPEG2 高畫質之外,亦支援 MPEG2 標準畫質格式,可相容於既有的標準畫質電視機或機上盒。
  • 03 設定簡便 — 頻道號碼可透過內建按鍵開關輕鬆設定。更進階的設定可由 PC/NB 或平板等外部主機透過 USB 介面完成。
  • 04 穩定可靠、傳輸距離長 — 只需一條 3C2V/RG59 纜線即可輕鬆傳送 1080p 影像達至少 500 公尺,中途無需加裝任何轉發器。用於無線應用時,在 0dBm RF 輻射功率下視距傳輸距離可達 50~100 公尺,在 20 dBm 下可達數公里。實際距離取決於天線設計與接收機品質。另提供差動 RF 輸出,可改用雙絞線(電話線或乙太網路 RJ-45)取代笨重的同軸纜線來分配 RF 訊號。
  • 05 串接佈線(匯流排拓撲) — 多台設定為不同頻道的 HV-102 可共用同一條纜線,大幅降低佈線的成本與工時。
  • 06 即時協定與低延遲 — 在 QEF(準無誤碼)條件下不會掉幀,且傳輸延遲低。

  • Note 1: output formats supported depend on the video input formats. The frame rate should be consistent and the encoded video frame size should be less or equal to the original input.
  • Note 2: For VGA-input, the encoded frame size can only be the same as the input.
  • There could be MER loss in high gain/attenuation level.
  • Specifications are subject to change without prior notice.
