2 COM2000 PRODUCT DESCRIPTION

A COM360 chassis fully populated with COM46 receivers is capable of tuning and transcrypting

up to 48 DIRECTV channels. The satellite signal is tuned and demodulated resulting in a

DIRECTV Legacy or MPEG-2 transport stream. This transport stream is then IP-encapsulated

using standard Internet protocols and RFCs and is sent out via the Ethernet interface over the

chassis backplane. The data can then either be routed to an internal QAM6 modulator or sent to

an external edge QAM device or for distribution on an IPTV network. The original DIRECTV

broadcast video encoding format (MPEG-2 or MPEG-4 compression) is preserved and the output

transport stream is encrypted with the Pro:Idiom (or other optional) encryption standard.

Multiple COM360 chassis can be “stacked” in order to provide more than 48 output channels.

While there is no technical limit to the number of COM360 chassis that can be configured in this

manner, the DIP switches used for setting individual chassis IDs are only capable of providing

16 unique identifiers. Refer to Section 4.1 for more information on this topic.

The COM46 receiver cards are controlled and managed via an Ethernet connection and do not

contain an internal video decoder for viewing the currently tuned channels. The COM46 card

does not operate like a traditional DIRECTV receiver. Specifically, COM46 cards do not

perform any MPEG video or audio decoding. They do not provide a traditional Middleware

based User Interface, and do not require a remote control device. The COM46 card includes a

built-in web interface and must be configured using a web browser. The video output of a

COM46 receiver can be viewed on a properly equipped commercial Pro:Idiom television or

Pro:Idiom capable set-top box. Manufacturers of this equipment include but are not limited to

LG, Phillips, Samsung, Sony, Enseo, and Technicolor.
