Continuing on to the device code we have:
Word 21,22 0018 0018 (24,24 decimal) Burst Pair 8, bit 1 = "0"
Word 23,24 0030 0018 (48,24 decimal) Burst Pair 9, bit 2 = "1"
Word 25,26 0018 0018 (24,24 decimal) Burst Pair 10, bit 3 = "0"
Word 27,28 0030 0018 (48,24 decimal) Burst Pair 11, bit 4 = "1"
Word 29,30 0030 0018 (48,24 decimal) Burst Pair 12, bit 5 = "1"
Word 31,32 0030 0018 (48,24 decimal) Burst Pair 13, bit 6 = "1"
Word 33,34 0018 0018 (24,24 decimal) Burst Pair 14, bit 7 = "0"
Word 35,36 0018 0018 (24,24 decimal) Burst Pair 15, bit 8 = "0"
Word 37,38 0030 0018 (48,24 decimal) Burst Pair 16, bit 9 = "1"
Word 39,40 0018 0018 (24,24 decimal) Burst Pair 17, bit 10 = "0"
Word 41,42 0018 0018 (24,24 decimal) Burst Pair 18, bit 11 = "0"
Word 43,44 0030 0018 (48,24 decimal) Burst Pair 19, bit 12 = "1"
Word 45,46 0018 03fc (24,24 decimal) Burst Pair 20, bit 13 = "0"
The device code as transmitted is 0101110010010. Reversing the order to make it
a binary number we get 0100100111010. Converting it to decimal we get 2362.
This means that the Sony DVD S7000 has a device code of 2362 and this key has
a function code of 46. This is the discrete Power ON key. If a Sony device has a discrete
Power on Code it is normally 46. Note the dead time on the second half of the last data
burst pair. Sony does not use a unique lead out, but rather adds the inter-message
minimum time to the last data burst’s off period
Sony codes are fairly simple. Sony builds a lot of power into the IR senders, and
good noise rejection in their receivers. They use no redundancy or error checking in the
code
