MLIN anybody watching this one. Some positive news in DVD market. Monday December 14, 8:01 am Eastern Time Company Press Release SOURCE: Micro Linear Corp. Micro Linear's Video Encoder Chip Is First to Integrate Filters, Amplifiers And D/As High-Integration Encoder Chip Converts Digital Video Into Analog Video New Chip Eliminates the Need For up to a Dozen External Components Provides Macrovision(R) Copy Protection Technology Circuit for DVDs SAN JOSE, Calif., Dec. 14 /PRNewswire/ -- Micro Linear Corp. (Nasdaq: MLIN - news) today announced the industry's first video encoder chip to integrate output filters, amplifiers and D/A converters. Previously, up to a dozen external components were required to filter and amplify the analog output of a video encoder. The new device accepts an 8-bit wide, high-speed stream of uncompressed digital video from an MPEG decoder and converts it into analog video for playback on a monitor, or TV in NTSC composite or S-Video formats. The chip comes in two versions including the ML6461 for use in set-top boxes, digital cameras, camcorders, graphics add-in cards and personal computers. The ML6460 version includes Macrovision® copy protection technology for DVD applications. The devices are used in systems with digital video that must be converted back to analog for viewing. These systems typically store digital video in a compressed format using the MPEG (Moving Pictures Experts Group) industry standard. During playback, an MPEG decoder chip decompresses the digital video and feeds it into a Micro Linear encoder which converts or ''encodes'' the digital video back into analog video. The low cost of the new devices will allow them to be used to design ''TV ready'' video outputs in graphics add-in cards. This capability allows consumers to use their family TV to view DVD movies and other video running on their PC. The rapid growth in the use of digital video has put a lot of emphasis on the digital, MPEG solutions that compress and decompress the video. However, of equal importance are these mixed signal devices that convert the digital video back into the analog for playback on monitors and televisions. Device Features The Micro Linear devices each contain a timing generator, closed caption VBI (Video Blanking Interval) encoder, three D/A converters (each with 10-bits of effective processing), a summer circuit, two 6th order lowpass, reconstruction filters, and three 75 ohm video amplifiers. The 8-bit digital input port accepts YCrCb video in either CCIR601 or Square Pixel formats. The outputs of the chip include both composite and S-Video, and are capable of driving up to 300 feet of coaxial cable. The timing generator in the chips provide the synchronization pulses for chroma and luma generation. The closed caption circuit provides the signals needed to pass ''closed caption'' text through to a television during vertical retrace. The three D/A converters generate the Y (luma), C (chroma) and sync signals respectively which are passed through the internal reconstruction filters. A built-in summer circuit combines the Y and C signals to form composite and S-Video, and the 6dB video amplifiers boost the final outputs. Availability and Price The ML6460 which includes the Macrovision® copy protection technology is sampling now to Macrovision Licensees and will be in full production in January, 1998. It is priced at $8.00 for a 28-pin SOIC (Small Outline Integrated Circuit) in quantities of 1,000. The ML6461 (without Macrovision® copy protection) is sampling now and will also be in full production in January, 1998. It is priced at $8.00 for a 28-pin SOIC (Small Out-line Integrated Circuit) in quantities of 1,000.
