设备需求
• 1套3讯道EFP系统（包含切换台、摄像机、视频周边设备、文件化录制设备、通话设备等）
• 1套小型扩声及收声系统
• 2块显示屏 (舞台上一块，作为背景，舞台对面一块)
• 4-6台笔记本电脑，若干采集卡或2对(4台)srt设备
Equipment Requirements:
- 1 set of 3-channel EFP system (including switcher, cameras, video peripherals, file-based recording devices, communication devices, etc.)
- 1 set of small-scale sound amplification and collection system
- 2 display screens (one on the stage as a background, one opposite the stage)
- 4-6 laptops, several capture cards, or 2 pairs (4 units) of SRT devices
EFP系统说明
• 3讯道高清EFP系统，信号为HDSDI、信号格式为1080 50P
• 最终输出信号需加嵌2轨音频（CH1:PGM-L、CH2:PGM-R）
• 需1位导播及2-3位摄像师、相应技术人员
• HDMI转SDI，SDI转HDMI的转接器若干，高清采集卡若干（配合电脑画面转换成SDI信号等）
EFP System Specifications:
- 3-channel high-definition EFP system, signals are HDSDI, signal format is 1080 50P
- Final output signal needs to embed 2-channel audio (CH1: PGM-L, CH2: PGM-R)
- Requires 1 director, 2-3 camera operators, and corresponding technical staff
- Several HDMI to SDI and SDI to HDMI converters, several high-definition capture cards (for converting computer screens into SDI signals, etc.)
优点：
1、延时量稳定、且最低，具有2对(4台)设备即可解决3路信号的高码率互相传输，安全可靠，画质最清晰。
2、点对点协议传输，没有经过第三方服务器，保密性高，受干扰几率小。
Advantages:
1. Stable and minimal latency; two pairs (four units) of devices can handle high-bitrate transmission of three signals, ensuring security, reliability, and the clearest image quality.
2. Point-to-point protocol transmission without passing through third-party servers, ensuring high confidentiality and minimal interference.
缺点：
1、由于国内外网络的差异性，具有不可控因素。
2、如上海无法携带该类型的设备，需要在美国当地解决部分SRT的硬件编解码设备。
3、对美国现场EFP、扩声系统、大屏系统有一定的技术要求。
Disadvantages:
1. Potential uncontrollable factors due to differences in Chinese and overseas networks.
2. If the Shanghai team cannot provide this type of devices, some SRT hardware encoding and decoding devices need to be arranged locally in the United States.
3. Certain technical requirements for EFP, sound amplification systems, and large-screen systems at the California venue.
