7743DLY-HD 是全功能的高清/标清视频延时模块，专门针对卫星上连、信号重返主控输入、电缆数据转发、机动车输出、广播发射器输入、虚拟设置和配合由多通道音频压缩而引起的延时而设计的。
7743DLY-HD 可以作为标清 SMPTE ST 259 视频或高清的延时。
7743DLY-HD 可以延迟达 3.2 秒高清和 16.5 秒标清。考虑到广播的环境，这些模块对输出提供了旁路继电保护。
The 7743DLY-HD occupies two card slots and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.
特点
- 具有对所有信号延时的能力，包括用于SMPTE ST 292-1 (1.5Gb/s) 信号的VBI和ANC数据
- 也支持对用于SMPTE ST 259 (270Mb/s) 信号的VBI信号的延迟
- 延时可设成以视频为单位(帧、行和取样)或以时间为单位(秒)
- 自动检测视频标准
- 旁路继电，用于节目路径在掉电时的保护
- 最高 3.2 秒高清延迟
- 最高 16.5 秒标清延迟
- 卡边控制工作于屏幕显示系统上，用于设置延时的设定
- 输入电路具有一行的缓冲，非常适用于在上游设备中热开关时的“减干扰“(对高清设备十分有用)
- VistaLINK® capable for remote monitoring, control and configuration capabilities via SNMP; using VistaLINK® PRO, CP-2116E or CP-2232E Control Panels. VistaLINK® is available when modules are used with the 3RU 7800FR frame and a 7800FC VistaLINK® Frame Controller module in slot 1 of the frame
