3 Copy Control Information (CCI) Two bits of Copy Control Information are too limited in conveying content management information.Two bits of Copy Control Information are too limited in conveying content management information. The MPA has proposed a new Extended Copy Control Information (ExCCI) data packet to provide a uniform data field for carrying a richer set of content management information.The MPA has proposed a new Extended Copy Control Information (ExCCI) data packet to provide a uniform data field for carrying a richer set of content management information.

5 Extended Copy Control Information (ExCCI) Byte 0: version Bits describe an integer number representing the version of the ExCCI data packet. V7V6V5V4V3V2V1V0

6 Extended Copy Control Information (ExCCI) (AC) ANALOG COMPONENT OUTPUT CONTROL AC=0 Analog component signal output not allowed. AC=1 Analog component signal output allowed. Byte 1: content_control0 ACDC1DC0 CGMS-Ab1 IC CGMS-Ab0APSb1APSb0 (DC) DIGITAL SIGNAL OUTPUT CONTROL DC1=0 & DC0=0 No digital signal output allowed. DC1=0 & DC0=1 Only uncompressed digital signal output allowed. DC1=1 & DC0=0 Only compressed digital signal output allowed. DC1=1 & DC0=1 Both compressed & uncompressed digital output allowed. COPY GENERATION MANAGEMENT SYSTEM - ANALOG SIGNALS b1=0 & b0=0 Copying is permitted. b1=0 & b0=1 No further copying is permitted. b1=1 & b0=0 One generation copy is permitted. b1=1 & b0=1 Copying is not permitted.

7 Extended Copy Control Information (ExCCI) (APS) ANALOG PROTECTION SYSTEM b1=0 & b0=0 Analog copy protection is not used. b1=0 & b0=1 Pseudo sync pulse is on & split color burst is off. b1=1 & b0=0 Pseudo sync pulse is on & 2-line split color burst is on. b1=1 & b0=1 Pseudo sync pulse is on & 4-line split color burst is on. Byte 1: content_control0 ACDC1DC0 CGMS-Ab1 IC CGMS-Ab0APSb1APSb0 (IC) IMAGE CONSTRAIN IC=0 High definition resolution content need not be image constrained when being transmitted over unprotected analog component outputs. IC=1 High definition resolution content must be image constrained to no greater than 600 vertical pixels when being transmitted over unprotected analog component outputs.

8 Extended Copy Control Information (ExCCI) (R) RETRANSMISSION CONTROL R=0 Content may not be retransmitted beyond the Home Network. R=1 Content may be retransmitted beyond the Home Network. (CCA) COPY CONTROL ASSERTION CCA=0 Copy control is not asserted, regardless of CGMS data. CCA=1 Copy control is asserted. COPY GENERATION MANAGEMENT SYSTEM - DIGITAL SIGNALS b1=0 & b0=0 Copying is permitted. b1=0 & b0=1 No further copying is permitted. b1=1 & b0=0 One generation copy is permitted. b1=1 & b0=1 Copying is not permitted. Byte 2: content_control1 XRCCA CGMS-Db1 M0 CGMS-Db0 M2M1 Note: All bits marked by ‘X’ are reserved and are currently defined as having a value = 1.

9 Extended Copy Control Information (ExCCI) (M2, M1, M0) COPY MOVE COUNT Define an integer value ‘M’ between 0 and 7 that means the following: M=0 A copy made of Copy Once content cannot (or can no longer) be moved. M=1 to 6 Number of times a copy of Copy Once content can be moved. M=7 A copy made of Copy Once content can be moved an unlimited number of times. Byte 2: content_control1 XRCCA CGMS-Db1 M0 CGMS-Db0 M2M1

10 Extended Copy Control Information (ExCCI) Byte 3: content_control2 Reserved bits for future use. XXXXXXXX Note: All bits marked by ‘X’ are reserved and are currently defined as having a value = 1.

11 Extended Copy Control Information (ExCCI) Byte 4: playback_count C7C6C5C4C3C2C1C0 Define an integer value ‘C’ between 0 and 255 that means the following: C=0 The temporary content recording can no longer be played. C=1 to 254 Number of times the temporary content recording may be played during the Longevity period. C=255 The temporary content recording may be played an unlimited number of times during the Longevity period.

12 Extended Copy Control Information (ExCCI) Define an integer value ‘L’ representing the number of minutes a temporary content recording is playable (up to 2 years) as described below: L=all 0s The temporary content recording can no longer be played. L=neither all 1s or all 0s Number of minutes the temporary content recording can still be played provided that the Playback Count value ‘C’ is =>1. L=all 1s The temporary content recording can be played indefinitely provided that the Playback Count value ‘C’ is =>1. Bytes 5, 6, 7: longevity_time L7L6L5L4L3L2L1L0 L15L14L13L12L11L10L9L8 XXXXL19L18L17L16 Note: All bits marked by ‘X’ are reserved and are currently defined as having a value = 1.

13 Extended Copy Control Information (ExCCI) Define an integer value ‘P’ representing the maximum number of minutes per occasion (up to 30 hours) that a temporary content recording can be paused as described below: P=all 0s The temporary content recording can not be paused. P=neither all 1s or all 0s Maximum number of minutes per occasion the temporary content recording can be paused. P=all 1s The temporary content recording can be paused indefinitely. Note: All bits marked by ‘X’ are reserved and are currently defined as having a value = 1. Bytes 8, 9, 10, 11: pause_time P7P6P5P4P3P2P1P0 XXXXXP10P9P8 XXXXXXXX XXXXXXXX

14 Extended Copy Control Information (ExCCI) Defines an integer value ‘S’ representing the number of GPS seconds after 12:00 midnight, January 6, 1980 when the temporary content recording can begin being played. When S=0, the start time mechanism is not used and the start time for Longevity is the time when the content was received. Bytes 12, 13, 14, 15: delayed_start_time S7S6S5S4S3S2S1S0 S15S14S13S12S11S10S9S8 S23S22S21S20S19S18S17S16 S31S30S29S28S27S26S25S24

15 Extended Copy Control Information (ExCCI) Optional reserved bits for future use and for carrying optional Copyright Notice information. Note: All bits marked by ‘X’ are reserved and are currently defined as having a value = 1. Bytes 16 to n: optional_bytes XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX
