[QUOTE="homercartman, post: 1078239, member: 414304"] After some probing, a small update regarding minimal conditions on decoder locking on PIC card : [LIST=1] [*]_vbi_sync[3] is critical and must be == 0x6D [*]_vbi_sequence[0] is critical and must be == 0x15 [*]_vbi_sequence[2] must have required bitmask 0x10 [*]_vbi_sequence[4] must have required bitmask 0x40 [*]_vbi_sequence[6] must have required bitmask 0x08 [/LIST] [LIST] [*]In above list, items 1 and 2 are critical and can't be different than this [*]Items 3 to 5 can be 0xFF. Seems the condition is that the bitmasks must be respected [*]any other bytes from vbi_sync and _vbi_sequence can be 0x00 or 0xFF. intermediate values are not tested. [*]zering _vbi_sequence[2], _vbi_sequence[4], _vbi_sequence[6] will lead to alternating "partial" lock / complete unlock phases. Partial lock being: decoder only locks on audio and vertically realigns picture, but line descrambling never happens. [/LIST] In other words: [CODE] static const uint8_t _vbi_sync_test[4] = { 0xFF, 0xFF, 0xFF, 0x6C }; // works static const uint8_t _vbi_sync_test[4] = { 0x00, 0x00, 0x00, 0x6C }; // also works static const uint8_t _vbi_sequence_test[10] = { 0x15, 0x00, 0x10, 0x00, 0x40, 0x00, 0x08, 0x00, 0x00, 0x00 }; //works static const uint8_t _vbi_sequence_test[10] = { 0x15, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF }; //also works [/CODE] Hope this helps!
