`“TIME WARNER CABLE AND SAMSUNG FORGE AGREEMENT FOR TRU2WAY SET-TOP DEVELOPMENT,
`PURCHASE & DEPLOYMENT
`Release Date: 07/06/2009
`
`Time Warner Cable and Samsung today announced that they have signed a letter of commitment for the continued development,
`purchase and deployment of Samsung True2Way enabled set-top boxes, including the first second-source DVR.
`“We look to offer our customers advanced set-top boxes with features that are simple and easy to use,” said Mike Hayashi,
`Executive Vice President of Advanced Engineering for Time Warner Cable. “We have been a leader in the roll-out of Tru2Way
`devices and we are continuing to grow our relationship with Samsung, a CE company dedicated to the development of new
`equipment meeting the necessary standards and offering attractive feature sets.”
`Thomas Rhee, SVP, New Business Development for Samsung, added, “We are thrilled to have worked closely with Time
`Warner Cable to launch Tru2way on our family of cable set-tops including the SMT-H3090 and SMT-H3270 High Definition
`DVRs. As in Korea, we look forward to the expansion of Tru2way in North America.”
`This agreement further solidifies Time Warner Cable’s commitment to its deployment of Tru2Way enabled set-top boxes. To
`date Time Warner Cable has deployed over 2 million Tru2Way set-top boxes, of which approximately 400,000 are Samsung
`boxes.
`Time Warner Cable and Samsung also recently signed an MOU that focuses on collaborating in development of better home
`
`1 In this chart, reference is made to a Samsung DVR identified as SMT-H3090. The same analysis applies to other Samsung DVRs with the
`same functionality, including but not limited to set top boxes with DVR functionality bearing the model designations, SMT-H3272, SMTH3270, and
`SMT-H4372 and other DVRs having the same functionality. Additionally, this chart also references the specific processor included in the SMT-
`H3090. The same analysis applies to DVRs that include other processors with the same functionality, for example the processors in each of the
`accused DVRs.

`A Samsung DVR accepts television broadcast signals. On information and belief, Samsung DVRs receive television
`programming in the form of QAM-modulated MPEG2 transport stream packets.
`
`See, e.g., (Samsung SMT-H3090 2008 Data Sheet), p.1 (“Samsung SMT-H3090 is Dual tuner Digital Video Recorder(DVR)
`which provides Standard Definition (SD), High-Definition(HD) and Analog video signals. Dual tuner DVR allows cable

`(showing BCM3420 and BCM3255 chips)
`
`On information and belief, Samsung DVRs accept ATSC broadcast signals.
`
`A Samsung DVR has tuners which can tune TV signals to a specific program. See, e.g., (Samsung SMT-H3090 2008 Data
`Sheet), p.1 (“Samsung SMT-H3090 is Dual tuner Digital Video Recorder(DVR) which provides Standard Definition (SD),
`High-Definition(HD) and Analog video signals. Dual tuner DVR allows cable subscribers to watch and record two HD
`programs Simultaneously.”"), p. 2 ("In-band Tuner : 54 to 864MHz, Receiving 64 or 256 QAM.")). For example, based on
`information and belief the Samsung DVRs tune to a specific frequency or a band of frequencies.
`
`A Samsung DVR has at least one Input Section, wherein said Input Section converts said specific program to a Moving Pictures
`Experts Group (MPEG) formatted stream for internal transfer and manipulation. The Input Section converts said specific
`program to an MPEG formatted stream, for example in the course of performing QAM demodulation and Analog-to-Digital
`conversion (A/D). A Samsung DVR will perform QAM demodulation and Analog-to-Digital conversion in the course of
`watching live television and recording a television program. See, e.g.,

`On information and belief, the MPEG stream is separated into its video and audio components, for example, the course of PID
`filtering, start code detection, and temporary storage in memory. Additionally, the streams are separated when presented to the
`video and audio decoders. In the course of PID filtering and start code detection, on information and belief, MPEG2 transport
`stream packets are discretely analyzed. Each MPEG2 transport stream packet contains audio or video data. The MPEG2
`transport stream packets are temporarily stored in memory (e.g., on-chip buffers, flash, and/or system DRAM), where each
`MPEG2 transport stream packet is held in a distinct memory location. As another example, the video and audio data packets of
`the MPEG data are separated when they are sent to separate decoders. For example, audio packets go to audio decoders while
`video packets go to video decoders

`For example, when a Samsung DVR receives and records digital input stream, it may include a time stamp, such as a
`presentation time stamp (PTS) that is included in that stream. The PTS will be extracted and stored with the input data stream.

`
`Time Warner Cable and Samsung today announced that they have signed a letter of commitment for the continued development,
`purchase and deployment of Samsung True2Way enabled set-top boxes, including the first second-source DVR.
`“We look to offer our customers advanced set-top boxes with features that are simple and easy to use,” said Mike Hayashi,
`Executive Vice President of Advanced Engineering for Time Warner Cable. “We have been a leader in the roll-out of Tru2Way
`devices and we are continuing to grow our relationship with Samsung, a CE company dedicated to the development of new
`equipment meeting the necessary standards and offering attractive feature sets.”
`Thomas Rhee, SVP, New Business Development for Samsung, added, “We are thrilled to have worked closely with Time
`Warner Cable to launch Tru2way on our family of cable set-tops including the SMT-H3090 and SMT-H3270 High Definition
`DVRs. As in Korea, we look forward to the expansion of Tru2way in North America.”
`This agreement further solidifies Time Warner Cable’s commitment to its deployment of Tru2Way enabled set-top boxes. To
`date Time Warner Cable has deployed over 2 million Tru2Way set-top boxes, of which approximately 400,000 are Samsung
`boxes.
`Time Warner Cable and Samsung also recently signed an MOU that focuses on collaborating in development of better home
`networking solutions for entertainment. This work is part of Time Warner Cable’s continuing efforts to provide its customers
`with technology that brings new levels of ease and convenience.”
