To transmit a signal, a controller sends it through the horn, and the dish focuses the signal into a relatively narrow beam. The standard dish consists of a parabolic (bowl-shaped) surface and a central feed horn. A satellite dish is just a special kind of antenna designed to focus on a specific broadcast source. When the signal reach to the viewer house, the satellite dish captured the signal. Dynamic data capturing (subtitles, teletext, etc.).All above listed application fields for Fusion 878A show that it is a multi-fucntional chip, so you can see it not only inside a TV-tuner The chip can be used in the following devices:
#ASTRO AUDIO SPLITTER SERIAL#
Receives digital audio data via the serial I2S port Integrated color saturation filter (chroma) and signal brightness frequency divider (luma)
#ASTRO AUDIO SPLITTER 32 BIT#
Adjustable pixel density: 8, 16, 24 and 32 bit per pixel
#ASTRO AUDIO SPLITTER TV#
Interface for processing Digital TV data from the television demodulator CCIR656 interface (International Radio Communication Committee) RF parallel port (20Mbit/sec) for MPEG-streams transfer RF serial port (40Mbit/sec) for MPEG-streams transfer HDTV/Audio/MPEG2 data transfer via the PCI bus Integrated module managing the data transfer via the PCI bus Image capturing up to 768x576 pixels (PAL) Stereo decoding of the audio signals for TV and FM
Here are the major technical specifications of Fusion 878A:
#ASTRO AUDIO SPLITTER PC#
From this point of view, Fusion 878A can be also used as a PC hub managing numerous analog and digital video formats via the PCI connection. The worlds moves to digital technologies with new broadcast standards, such as ATSC and COFDM, and television recording is actively involving MPEG compression. Fusion 878A can also be used in a wide range of digital products, which need to manage MPEG streams.

The decoder meets the requirements of the PC98/PC99 specification and complies with PCI 2.2 standard.įusion 878A chip is similar to Bt878 not only in terms of its software compatibility, but also on the hardware level (here I am talking about the same internal chip layout, which makes it much easier to replace the Bt878 with a Fusion 878A without redesigning the pinout and PCB layout). Fusion 878A inherited all the goodies of Bt878 chip and added a few new functions of its own to the list. It ensures high bandwidth for multi-media streams of data and should work with some other PCI devices as a component of their electronics. Fusion 878A is a kind of link between the PCI bus and TV-tuner card. It is a fully-fledged low-cost single-chip solution and is responsible for processing signals coming from the television and radio companies. We will offer you captured TV images for all 6 TV-tuner models reviewed today, so that you could take a closer look and make your own conclusions about this or that card.įusion 878A seems to be one of the most widely spread decoders. The real tests will show though, how the things actually stand with the image quality. In the long run it should result into better image quality in our case. Even by simply comparing the useful functions of the chips we can conclude that the solution from Philips is better suited for work with SECAM standard. Two types of alternative settings for active video image scaling Horizontal and vertical picture scalability including the enlargement and reduction of the picture size Brightness, contrast, saturation and hue control
Three-level detection of the copy protection system - Macrovision Adaptive comb-filter for NTSC and PAL, which also works for non-standard signals Now I would like to list the major specifications of the Philips SAA7130HL chip: So, I believe it makes sense to pay special attention to the TV-tuners built on the latest chip modifications, because stereo is always better than mono. I would like to draw your attention to the fact that NICAM digital encoding is implemented only in 7134HL and 7135HL modifications. The comparative table below is a pretty interesting thing to check out, that is why I decided to put it here: Philips decoder exists in four different modifications today: 7130HL (basic or the simplest modification), 7133HL, 7134HL and 7135HL. Analog audio signal is transferred via the connection cable to the system sound card. The decoded image is displayed in YUV and RGB formats. The analog signal is received by a 9bit ADC, decoded by multi-string combo-filters and scaled along horizontal and vertical axes. It transfers different types of multimedia data via the PCI bus. It is also a highly integrated low-cost single-chip solution that suits perfectly for capturing analog and digital broadcast. Although I would consider this chip not an alternative but the newest electronic analogue. An alternative solution is the SAA7130HL decoder from Philips.
