Latency doesn't matter at all. Jitter is taken care of by jitter buffers in the STB and will not be problem with any well designed IP network. Jitter hasn't been a problem in any IPTV networrk I have seen. Packet loss is evil - any lost paclets show up either as lost video or audio. You can add FEC, but some SIP STBs are not going to have the processing power to do FEC in software and there aren't any IP STBs with hardware FEC support. Some MPEG-4 system do really long time jitter buffers and retry on lost multicast packets. Your middleware vendor better have the answer to all of the questions or you picked the wrong vendor...
