Reference excerpt

The Thomson DTI 6300-16 (or 6300-25 to denote the 250GB version) was the first digital television recorder used to access Top Up TV’s push video on-demand service. The device first launched on the market in 2006. Previously the Top Up TV Freeview+ box was known as the Top Up TV+ BOX and the Top Up TV Anytime DTR. connections to the TV and external equipment are made at the rear of the box whilst at the front is the remote sensor, coloured LEDs, viewing card slot and front panel controls.

Packaging Included in the packaging is a Top Up TV remote control and SCART lead, a signal improvement kit, an RF lead and a power cable. Printed materials include the Top Up TV welcome pack, a remote control codes guide and an instruction manual. The rear of the box has two SCART sockets, two TV tuners, an S-Video output, analogue phono output and digital audio output. It features a powered but functionless USB port on the front or rear of the DTR.

Firmware The system software is developed by Top Up TV by Kieron Edwards and the other members of the Technical team at Top Up TV. The overnight downloads and existing pay TV "live" channels like ESPN and Gold use the Nagravision Merlin encryption system (in chameleon mode) after a card swap in 2008. For interactive services the box has a fast MHEG5 v1.06 engine. It is also capable of receiving MHEG Plus applications such as Betfair and Teletext Extra as of version 4.07 also both services are no longer available support in the software code remains. Whilst the box contains a 160GB HDD or a 250GB HDD in the DTI 6300-25 version, the box can be upgraded support up to 500GB HDD's. Top Up TV Freeview+ Box has received thirteen software revisions since its launch, these are for the Thomson DTI6300-16 (160GB) and DTI6300-25 (250GB) models:

There are newer models of the Top Up TV Freeview+ box manufactured by Thomson and Vestel (Wharfedale, Digihome, Bush, Sharp, Metronic etc.) which have different firmware versions to the above.

Problems The Box in its early life had numerous problems which have mostly been fixed by over the air updates. The most notable bug was the Fast Forward and Rewind bug fixed in version 3.59 which caused the box to forget its position in a recording and jump back to the beginning. The box is prone to freezing in standby for no apparent reason but control can be restored by power cycling the box. There is also a problem with the aspect ratio (AFD), where the aspect ratio does not automatically correct itself when switching from a 16:9 programme to a 4:3 programme and vice versa resulting in a stretched picture. This problem started with version 4.07 but was not addressed in the minor release 4.09. This can often be manually corrected by switching to standby and back or through the box setup menus. If not, then it can be corrected by altering the aspect ratio on the TV, rather than the box. It is widely believed that problems with the box is one of the main reasons why customers choose not to resubscribe after their first free month. During the life of the software more bugs continue to emerge or be introduced. System hangs are not uncommon, the accepted (recommended) solution is to unplug the box from the wall, and re-power after twenty seconds. Recorded files can be "corrupt", such corruption can cause failures to the normal operation of the box. If the user changes channel on one receiver or uses Fast Forward and Rewind on one file this can cause video jumps in files that are being recorded. Many of the problems of crashes while recording, are caused by the box running out of disk space. The free space figure shown on the library menu, is not the amount that the box really believes is on the hard drive. In order to find out the real figure that the box uses, go to Main menu->Set-up->Help. At the bottom of the page, it tells you if the disk is present and the percentage free. If the box runs out of space while recording it may crash immediately, or appear to function normally until the scheduled end of the recording and then crash. If the latter is suspected selecting 'watch from the start' on the planned recordings menu, and viewing the playback timer will indicate if it has run out of space or not. If the recording is ongoing, the playback timer will not decrease at normal playback speed. If it is decreasing it is possible to abort the recording to stop the box crashing, with the option of saving the part of the programme already recorded. To reduce the chances of the box crashing while not viewing, leave the box on, rather than on standby, and on the main menu. Deleting recorded programmes from the programme library while recording another programme, is also quite likely to cause the box to crash. There has also been a problem related to the power-supply design, which contained 2 low quality capacitors (1000 microfarad; 16 volt) when first manufactured that couldn't cope with the high charge & discharge rates demanded of them and which tended to fail after about 2–3 years of use, leading to a totally dead recorder.

Awards In 2007 the Thomson DTI 6300-16 won the Computer Shopper award for best hard disk based recorder on the market.

Worked examples

Example 1 — a first encounter with Thomson DTI 6300-16

Start with the simplest possible case. Write down what Thomson DTI 6300-16 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Thomson DTI 6300-16 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Thomson DTI 6300-16 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Thomson DTI 6300-16

In research: Thomson DTI 6300-16 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Thomson DTI 6300-16 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Thomson DTI 6300-16 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Digital video recorders, so understanding it makes those chapters shorter.
In everyday life: Look for Thomson DTI 6300-16 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
