Installation procedure
Signal HD-507 A99250 is the only device on the market, which offers so much for so little. A small, practical case houses DVB-T receiver and multifunctional multimedia device. The use of this digital receiver is one of the cheapest ways to adapt an older CRT, LCD, or plasma television (if the LCD or plasma TV has only an MPEG-2 tuner) for the new world of digital television using MPEG-4. Even the owners of fully-featured televisions equipped with MPEG-4 tuners may also be interested in such a multifunctional device due to its integrated media player and Personal Video Recorder option (PVR Ready - possibility of recording DVB-T broadcasts on external USB memory). Signal HD-507 can also play pictures, music and videos - including those in high definition.
The biggest practical advantage of the A99250 receiver is compact size. The device can be directly plugged into the SCART input of a TV set - it remains virtually invisible to the user. The receiver is also ideal for any LCD/Plasma TV placed on a wall - depending on the TV model and mount, the user can arrange the device so that it fits in between the TV set and wall (adequate ventilation is required).
Hidden behind the television, the device receives commands from remote control via IR sensor on a short cable. To work properly, the sensor has to be attached somewhere on the front of the TV set.
Remark: The IR sensor of the receiver is equipped with LED indicating status of device - a feature not available in similar devices in the market!

The receiver is compatible with the most popular MPEG-4 compression standard and with the earlier version - MPEG-2 - used in some European countries. The device provides excellent image quality both in SD and HD resolution. The USB port (PVR Ready) allows to record the received broadcasts on external data storage device, such as a USB hard drive or a flash drive.
HDMI output provides signal of the highest quality, suitable for HD broadcasts. Using this connection, the receiver can be plugged into the SCART socket or not. With the simultaneous use of both types of connections, HDMI has priority.
- Signal HD-507 A99250 is intended for users who want to hide the receiver behind their televisions. It is the only model in the market which employs IR sensor and LED status indicator mounted on additional cable. This way, the user can control the receiver despite it is invisible behind the TV, being directly inserted to its SCART socket (no need for an additional cable).
- Signal HD-527 A99252 is dedicated for users who prefer traditional solutions with set-top-boxes. The receiver has two SCART outputs and S/PDIF output. The additional SCART and audio output are used for connecting an audio amplifier.
DVB-T
The receiver is fully compatible with the DVB-T standard (ETSI ETS300744) and allows to receive digital FTA (Free-To-Air) channels in SD and HD resolution (HDMI output), compressed in MPEG-2 or MPEG-4 standard. It is equipped with functional and clear Electronic Program Guide (EPG) containing detailed information on programming for the current day and the whole week (depending on the level of the service from the broadcaster). Navigating the menus of the receiver should not be a problem even for those who have no experience in the use of such devices.
PVR
Signal HD-507 with PVR Ready function allows to record selected programs on external memory device. It recognizes FAT32 and NTFS file systems. An external hard drive has to be powered from suitable power supply.
Available recording modes:
- instant recording (of the currently watched program)
- timer recording - schedule to start recording at a particular time and record for a certain length of time
- EPG recording - recording of programs chosen from the guide
Files recorded on an external data storage device are recognized by PCs as *. ts files. To play them back, the user should employ VideoLan Player (VLC) - free application that can be downloaded from the software developer site.
Multimedia
Signal HD-507 A99250 is also a fully-featured media player. The user can play pictures, audio and video files.
Supported file formats:
- Audio: MP3, WMA
- Pictures: JPEG, BMP, PNG
- Videos: MKV, AVI, VOB, MOV, DivX
An interesting feature is the possibility of playing files compliant with open standard Matroska (MKV). This format allows compression and recording of High Definition channels. It is characterized by good video quality and comparatively low memory consumption.
