BIGTV does have Y Pb Pr component video O/P
component Video
Y,Cb,Cr component video :refers to an interlaced scan-only component video connection. A Y,Cb,Cr connection typically is not capable of passing through a high defintiion video signal.
Y Pb Pr Component video: is capable of carrying signals such as 480i, 480p, 576i, 576p, 720p(HD Ready TV's), 1080i and 1080p(Full HD Tv's). (
Component video - Wikipedia, the free encyclopedia)
So,
HD video signal over component will work fine, but to get
HD Sound ,18MBPS & above audio signal of True HD and HD MA, will require HDMI, only HDMI has the required bandwidth to carry both the video and the sound signal(because component carries only video signal).
MPEG-4
MPEG-4 is simply a newer, more efficient compression algorithm. For the same image quality, MPEG-4 will produce a lower bit rate, requiring less bandwidth aka higher compression.
And at the same bit rate, MPEG-4 provides a higher quality image. The reason satellite providers are switching to MPEG-4 from MPEG-2 is because they can get the same image quality with less bandwidth. MPEG-4 is a compression standard that can be widely used not only for satellite transmissions but even for terrestrial TV, CATV, and even IP (Internet Protocol) TV.
BOTH Mpeg-2 and Mpeg-4 technologies can send HD Signals via compression algorithm, MPEG4 High Def will use less bandwidth than a MPEG2 High Def, So bigtv might use MEASAT high definition (HD) video distribution solution for HD channels(see below).
"US goes MPEG-4 for high def services, HBO USA announced that all of their HD program's will now be distributed in MPEG-4 instead of MPEG-2" .

MESAT 3 sattellite systems
MEASAT has been cooperating with the industry's leading players to bring together a high definition (HD) video distribution solution tailor-made for the Asian market.
Developed with the support of Scientific-Atlanta and TANDBERG Television, leaders in MPEG-4 compression systems. TANDBERG Television say's ??Because of the benefits of MPEG-4 and DVB-S2 it is able to transmit an HD signal using the same transponder bandwidth that is currently being used for Standard definition(SD)".
