404.1 UNICAST VS MULTICAST Unicast = one to one Multicast = one to many High Bandwidth required between the video source and a number of end-usersVideo source make separate video streams for each recipientReduced Bandwidth requirements between video source and multiple end-usersNetwork devices (routers) makes copies of video stream for every recipientUnicast = one to oneMulticast = one to many
414.2 UNICASTINGUnicasting is the traditional way that packets are sent from a source to a single destinationEach user who wants to view the video must make a request to the video source.The source needs to know the destination IP address of each user and must create IP packets addressed to each user. As the # of viewers increase, the load on the network increasesEach viewer gets a custom tailored video stream which allows the video source to offer specialized features such as pause, rewind and fast-forward of video.VODServerUnicasting
424.3 MULTICASTINGMulticasting unlike Unicasting, puts the burden of creating streams for each user on that network devices (routers) rather than on the video sourceIP Packets are given special IP Addresses to be recognized by the network as Multicast. Multicast Address Range, Class D: toIP Multicast uses UDP (User Datagram Protocol) packetsIGMP (Internet Group Management Protocol) controls access to Multicast streamsUser must request to Join and Leave Multicast streams (SPTS or MPTS)TM IPTV multicast IP range : xxxMulticasting

556.2 STB ERROR CODESTB Error does not just contain STB problem, it is composed by 5 sub-error code, each means a kind of service . Compared with EPG error code, STB error code concerns more basic services.The STB error code is classified by the first 3-digits number.ERROR CODERelative ServiceDescription102xxxNetwork problemUser can not access the IPTV platform103xxxUpgrade problemUpgrade STB version error104xxxVOD problemPlay VOD service error105xxxCA problem108xxxWebpage problemWebpage access errorPage 55

586.5 EPG ERROR CODE (20XXXX & 901XXX) EPG Error Code and STB Error Code are different, Main concern about EPG error code is regarding EPG operation and EPG server condition problem. For example: bookmark，lock/unlock，username/password, etc. , Therefore these errors usually easy to locate and solve. EPG error codes can be categorized as EPG service operation and EPG service status：Error CodeCategoryDescription20xxxxEPG service operationEPG service application problem901xxxEPG service statusEPG service status abnormal problemPage 58
