Abstract: A solution for allowing conditional access to IP-based broadcast services in a passive optical network is disclosed. When a subscriber requests broadcast services by selecting a broadcast channel, an IP set-top converts the request into an IGMP join message and forwards the message to an ONU/ONT, a unit on the subscriber's side. The ONU/ONT delivers the message to an OLT interworking with a router while storing mapping information of the port that received the message and a MAC address of the selected channel. Thereafter, the OLT extracts information on MAC address of the IP set-top box and the requested broadcast data. The OLT compares the extracted information to the subscriber's subscription information and determines whether to provide the requested broadcast services. If the broadcast services may be provided, the broadcast data provided from the broadcast server is transmitted to the IP set-top box via ONU/ONT based on the stored mapping information.

Abstract: A semiconductor memory device generates a test clock signal (whose periods and cycle number are variable) having a shorter cycle than that of an external clock signal, and internally test data using the test clock signal. The semiconductor memory device may repeatedly perform read/write operations using the internally generated test clock signal during a half cycle of the external clock signal. By comparing output data in the read operation with known data, a test apparatus may determine whether memory cells of a memory device are normal. In a low-frequency test apparatus, it is possible to screen disadvantages that may occur when a high-speed memory device operates at a high frequency.
