如何使用Ruby解码此EDID字符串？

require 'base64'

def decode_edid(edid_string)
  # 将EDID字符串解码为二进制数据
  edid_data = Base64.decode64(edid_string)

  # 解析EDID数据
  edid = {
    manufacturer_id: edid_data[8..9],
    product_code: edid_data[10..11],
    serial_number: edid_data[12..15],
    manufacture_week: edid_data[16],
    manufacture_year: 1990 + edid_data[17],
    edid_version: edid_data[18],
    edid_revision: edid_data[19],
    # 其他EDID信息...
  }

  return edid
end

# 示例EDID字符串
edid_string = "AP///////wBMLTg5OAQEBDwAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA"

# 解码EDID字符串
decoded_edid = decode_edid(edid_string)

# 打印解码后的EDID信息
puts decoded_edid
