Abstract
A host device, a point of deployment (POD), and a method for recognizing an operation mode are disclosed. The host device interfaces with a point of deployment (POD), and includes an interface unit and a controller. The interface unit includes CD1#, CD2#, VS1#, VS2#, VPP1, VPP2, and IPDET ports. The controller outputs a mode confirmation signal to the POD via the IPDET port, and identifies that the POD supports an Internet Protocol (IP) Card M-Mode when the mode confirmation signal has been applied to the VS1# and VS2# ports.
Claims12
A host device interfacing with a point of deployment (POD), the host device comprising:
- an internet protocol (IP) physical interface unit configured to receive an Ethernet frame including an IP packet which contains first moving picture experts group (MPEG) transport stream (TS) packets through an IP network which is external to the host device;
- a broadband interface unit configured to receive a cable broadcast signal delivering second MPEG TS packets through a cable;
- a demodulating unit configured to demodulate the cable broadcast signal;
- a routing engine configured to route the IP packet based on destination information included in the Ethernet frame;
- a decapsulator configured to extract the first MPEG TS packets from the IP packet;
- and
- a multiplexer, which is located at the host device, configured to multiplex the first MPEG TS packets extracted from the IP packet and second MPEG TS packets delivered in the cable broadcast signal and send the multiplexed first and second MPEG TS packets to the POD.
A method of processing broadcast data in a host device interfacing with a point of deployment (POD), the method comprising:
- receiving an Ethernet frame including an internet protocol (IP) packet which contains a first moving picture experts group (MPEG) transport stream (TS) packet through an IP network ,and a cable broadcast signal delivering a second MPEG TS packet through a cable;
- demodulating the cable broadcast signal;
- routing the IP packet based on destination information included in the Ethernet frame;
- extracting the first MPEG TS packet from the IP packet;
- multiplexing the first MPEG TS packets extracted from the IP packet and second MPEG TS packets delivered in the cable broadcast signal, by a multiplexer which is located at the host device;
- and
- sending the multiplexed first and second MPEG TS packets to the POD.
