Los rumores son ciertos, el stream de la HU esta siendo cerrado en estos momentos, Dave esta encriptando el packet Ins40 de autorizacion para hacerlo exclusivo de P4 como INS40s encriptados..
Yesterday DirecTV Started Shutting Down the following Channels and turning them over into P4 Native Video Authorization Only:
Sports Channels: 620 - 654
This is a Preliminary Report and will change as more Channels go down.
Directv Has changed the Decrypted P3/P4 Ins40 Video Authorization Packets to be Encrypted Ins40 P4 Native only Video Authorization Packets. Meaning that only P4 and P4 Based Access Cards will be able to process these Packets and here is why:
> 48 40 20 00 39 |Ins40 (INSParam1 = 20h INSParam2 = 00h INSLength = 39h) < 40 |Ins40 Acknowledgement > 7F |Cmd7F - Video Key Adjustment/Packet Signature Adjustment (P3 Ignores) 11 |Cmd7F Length 23 7C 57 BD A3 DB 80 D4 B5 D4 |Cmd7F Data 85 9A 3B 32 3B 2C 31 : 90 |CMD90 - Set packet Encryption 24 |CMD90 Length B0 |Use Primary Key #1 (Decrypted Packet) 23 |P3(HU) native Only 01 |Cmd01 - Date/Time Stamp 91 0B 1E 79 | 2/10/2004 10:49:08 EST 02 41 |CMD02 - Program Rating 01 - NR 82 |Cmd82 - HU Dynamic Code 07 |Cmd82 Length 00 06 |Compared with DSW Value at 24E6h-24E7h 42 |Cmd82 Decryption Key 00 01 |Cmd82 - Hash Ranges 3FFFh-3FFFh B5 :0066: B5 clr A F9 :0067: F9 rts 03 33 42 00 |Cmd03 - Tier reference - Check if Tier 3342 is Present 03 62 0D 00 |Cmd03 - Tier reference - Check if Tier 620D is Present 67 |Cmd67 - P4 Packet signature 08 |Cmd67 length (Ignore, always 08) F7 EE 7E 8A 4C 76 CC 12 |Cmd67 Data < 90 20 |Packet Response
The code in Yellow does the following:
First this line:
Code: B0 |Use Primary Key #1 (Decrypted Packet)
If Bit 6 of the byte is on that the Packet is Encrypted. However in B0h Bit 6 is not on 10110000. So this is a Decrypted Packet.
Then this line:
Code: 23 |P3(HU) native Only
The HU Card does a Bitwise AND with this Byte against #03h. If the End Result is #03h then the Packet is for a P3 Card, If not then it does not process the packet. In this case 03 AND 23 = 03, So this packet will process on a P3 Card.
Now onto the New Packets:
Code: > 48 40 20 00 24 |Ins40 (INSParam1 = 20h INSParam2 = 00h INSLength = 24h) < 40 |Ins40 Acknowledgement > 90 |CMD90 - Set packet Encryption 22 |CMD90 Length D0 |Bit 6 on Use ASIC to Decrypt 24 |P4 Native Only 1B E2 29 59 EB 7C 36 A4 98 9A : 06 1A FC D8 D4 CC 3B F7 A4 97 : 1C 9F C5 B4 93 87 5A AD 6E 62 : B2 89 : < 90 20 |Packet Response
Now take a look at the Byte in red in this P4 packet that correspond to the Yellow packet in the P3 Packet:
First:
Code: D0 |Bit 6 on Use ASIC to Decrypt
In D0h Bit 6 is on, so we know that this Packet is Encrypted and needs to be Decrypted
Then this line:
Code: 24 |P4 Native Only
The Hu will fails this Test. 03 AND 24 = 0. So the HU will not process this Packet.
Also Notice the Absence the Cmd7F within the P4 Packet which also tells us that The MPEG Video Key is now being Generated from the P4 Card and not the P3 card for which is was previously being generated from.
Well it was a Good Run. Let the games begin. __________________ do YOU hashHU?

Well folks, it looks as though DTV is finally pulling the plug on the HU cards after a long 5 year run. Many people have already reported losing the sports (600's) and music (800's) channels. At first, we just assumed this was a regular hash but we have reports that an email was sent out entitled "Access Card Change-Out Channel Removal" with the following set schedule as to when the remaining channels will be shut down.
Date Channel April 13- Music Choice 800-821, 823-838,840-850 April 13- Para Todos 406-450, 452-499 April 13- Fox Sports Regional Networks 620-654 April 13- Adult PPV 594, 596-598 April 13- HD 73-100 April 13- PPVs 100-199 April 14- Premiums East 501,202,507,513,520,522,528,537,544 April 14- Core 1 (news religion...) 366-377, 337-358 April 16- Regional Sports Networks 2 601-612 April 16- Core2 (266-271, 282-287...) 266-271, 282-287, 291-295, 300-315 April 20- Seasonal Sports 700-799 April 20- Core 3 230-244, 297-298,276-279,207-212 April 21- Preimum Specialty 545-550, 523, 527-533,538-542 April 21- Core 4 248-265, 321-329, 333 April 22- Final1 822, 839, 595, 521, 514, 508, 505, 504, 503 April 23- Final2 402, 404, 335, 331, 317, 299, 296, 290, 280, 273, 224, 229, 203,204 April 27- Final3 360, 362, 245, 247, 202, 206 April 27- Locals/Distant Networks
If Dave sticks to this schedule, we are looking at complete HU datastream shutdown by the end of April assuming regular customers don't call in and complain....By Giovanni
