History
KVDO
The station was originally launched in 1954 as KVDO-TV, broadcasting on channel 22 as the Corpus Christi market’s first television station. KVDO was a primary affiliate of the DuMont network, but carried secondary affiliations with NBC until KRIS-TV took the air in 1956, CBS until KZTV signed on in October 1956, and ABC. It was one of several television stations across the United States that took part in a 1956 lawsuit to prevent VHF stations from being added in their markets, on the grounds that UHF stations in that era typically suffered financially or even went out of business entirely if they had any VHF competition. The lawsuit was unsuccessful, however, and KRIS and KZTV were both on air as VHF stations by fall 1956. Around the same time as the VHF stations were launched, as well, the DuMont network collapsed.
KVDO carried on as an independent station, and was sold to H. J. Schmidt’s South Texas Telecasting Company in April 1957. It temporarily suspended broadcast operations in August pending what was announced at the time as a reorganization of its studio layout, but a federal tax lien was filed against the station by the Bureau of Internal Revenue in September. In October the station received FCC approval to stay off the air until January 1958, but by November 1957, the former KVDO studio had been sold to KRIS-TV, and the station did not relaunch.
Dormancy and relaunch as KIII
Following the demise of the original KVDO, South Texas Telecasting petitioned the Federal Communications Commission (FCC) to add a third VHF allocation on Channel 3 at Corpus Christi due to KVDO’s failure as a UHF station. Other cities also wanted the Channel 3 allocation; however, following a lot of struggle, channel 3 was ultimately allocated to Corpus Christi, and hearings to award a license began in 1961. South Texas Telecasting was one of three applicants for the license, alongside Nueces Telecasting and the Corpus Christi Caller-Times, but the Caller-Times withdrew its application in 1962 after its owner, Harte-Hanks Newspapers, acquired the San Antonio Express-News.
South Texas Telecasting was awarded the license in December 1962, but Nueces Telecasting then filed a protest alleging that awarding the license to South Texas Telecasting would violate the FCC’s regulations on concentration of media ownership. Nueces withdrew its petition in June 1963 after South Texas Telecasting agreed to pay the company $40,000.
KIII
The station relaunched on May 4, 1964 as a full ABC affiliate, and retains that network affiliation today. It was originally planned to retain the original KVDO call sign, but its call sign was changed to KIII by the time it launched.
South Texas Telecasting, which had by this time added Clinton D. McKinnon as its major stockholder and executive vice president but still retained most of its original board of directors, later evolved into McKinnon Broadcasting, who remained the station’s owners until 2010.
In 1969, KIII started a satellite in Victoria, Texas, KXIX (channel 19), to bring ABC programming to that area. In 1976, KXIX was sold to local ownership. It now operates as Fox affiliate KVCT.
On April 29, 2010 it was announced that KIII would be acquired by London Broadcasting Company. which the sale was closed on August 31. On September 18, 2011, KIII began broadcasting newscasts in high definition.
On May 14, 2014, the Gannett Company announced that it would acquire KIII and five other LBC stations for $215 million. Gannett’s CEO Gracia Martore touted that the acquisition would give the company a presence in several fast-growing markets, and opportunities for local advertisers to leverage its digital marketing platform. The company also owns fellow Texas ABC affiliates WFAA and KVUE, which it had acquired in its purchase of Belo Corporation. The sale was completed on July 8. 13 months later, on June 29, 2015, the Gannett Company split in two, with one side specializing in print media and the other side specializing in broadcast and digital media. KIII was retained by the latter company, named Tegna.
KIII Pro Teardown
Let’s open the thing. We’ll have to start with the bottom cover. First we’ll notice a D0:76:58 MAC address which is not registered with IEEE, but the company previously explained that it was for “localized network, and it is the only ID for empowering applications to activate, specially IPTV applications”. Then, the box can be wall-mounted via two “hooks”, which can be convenient in some use cases. Finally, there’s a recovery pinhole on the right of the sticker in order to reinstall firmware if your box does not boot anymore.
Click to Enlarge
We don’t need to remove all rubber pads, as there are two just screws holding the case together. One under the bottom left rubber pad, and one under the QC sticker, which you need to pierce through. Once we’ve removed those two screws, the box comes apart easily.
We have two boards: main board with heatsink on the CPU, and a yellow board with the tuner circuitry.
Click to Enlarge
We’ll find two SpecTek DDR3 SDRAM chips: PE029-125 (512 MB) and another chip market “512X16DDR3” (1 GB) for a total of 1.5 GB RAM on this side of the board. The flash is covered by a sticker, which I have not removed, so we’ll see how storage performs in benchmarks. Gigabit Ethernet is done using Realtek RTL8211F transceiver, and Pulse H5900L transformer, while AC WiFi and Bluetooth LE is implemented via a module marked “KM63351412” which could be equivalent to AP6335 module found in some other devices. Other chips include GL852G USB hub, and DIO2133 audio driver. If you want to hack the board, the serial console should be available via an unpopulated 4-pin header on the bottom left of the photo above.
Click to Enlarge
The other side of the CPU board comes with a micro SD card slot, and 1.5 GB extra RAM to bring the total to 3GB. We can also see extra cooling with a thick metal plate, covered by a black sheet, itself covered by a thin plastic transparent sheet on the bottom of the enclosure.

S2&T2_R848_REV1.2 tuner board looks very similar to KI Plus tuner board, but just upgraded from Revision 1.0 to Revision 1.2, and featuring the same Availink AVL6862TA DVB-C/T/T2 + DVB-S/S2 demodulator, but they changed Rafael Micro R848 tuner chip to R912 model, which is not documentated on Rafael Micro website yet.

The power bottom can conveniently be found on the top cover, one side has four USB 2.0 host ports, a micro SD, and the rear panel features a DVB-T2 coaxial connector, a DVB-S2 F connector, CVBS/LR composite + stereo audio 3.5mm jack, a Gigabit Ethernet port, a HDMI 2.0a port, optical S/PDIF, and the power jack.
Производительность Mecool KI Pro
В устройство встроен 4-ядерный процессор Amlogic S905D, который работает в паре с графическим ускорителем Mali-450. Оперативной памяти здесь 2 Гб, а встроенной – 16 Гб. Из внутренней пользователю доступно около 11 Гб, но она расширяема, ведь присутствует разъем для карты памяти.
В Mecool ki pro производитель поставил Андроид 7.1 с последней прошивкой. После включения тв приставки главное меню загружается за 20-30 секунд. На рабочем столе уже есть ярлыки основных программ для начала работы. Причем меню адаптировано под управление пультом.
Микул – отличный медиаплеер. Поддерживаются практически все форматы аудио и видео вплоть до 4К. Есть возможность смотреть телевизионные каналы, фильмы, играть в игры и пользоваться андроид-приложениями на большом экране. Кроме того, реализована функция просмотра веб-страниц. А изюминка тв гаджета – показ каналов, которые в стране не транслируются. То есть, чтобы смотреть передачи всех стран, достаточно иметь интернет с хорошей скоростью.
Разбираем KIII Pro
Давайте откроем приставку. Начнем с нижней крышки
Обратите внимание на MAC адрес D0:76:58 который не зарегистрирован в IEEE, но ранее в компании поясняли, что этот адрес для “локализованной сети и он является только идентификатором для расширенной активации некоторых приложений, специальные IPTV приложений”. Еще бокс можно закрепить на стене с помощью двух “крючков”, что может быть удобным в некоторых случаях использования
И наконец в корпусе есть отверстие с кнопкой восстановления, справа от наклейки, кнопка служит для сброса и восстановления параметров устройства и перевода его в режим перепрошивки.

Нам не нужно снимать все резиновые ножки, так как там всего два винта крепящие корпус. Один из винтов находится под левой нижней резиновой ножкой, а второй под гарантийной наклейкой, которую вам придется прорвать. После того как винты будут откручены, корпус легко откроется.
Внутри мы видим две платы, основная с радиатором на процессоре и желтая плата со схемой тюнера.
Нажмите чтобы увеличить
На основной плате мы найдем два чипа SpecTek DDR3 SDRAM: чип PE029-125 (512 Мб) и чип “512X16DDR3” (1 Гб), что дает нам в общем 1.5 Гб оперативной памяти на одной стороне платы. Чип флеш памяти расположен под наклейкой, так что объем хранилища мы сможем узнать только во время тестирования. Для гигабитного Ethernet используется приемопередатчик Realtek RTL8211F и трансформатор Pulse H5900L, в то время как AC WiFi и Bluetooth LE реализованы через модуль с пометкой “KM63351412”, что похоже эквивалентно модулю AP6335 найденному в некоторых других устройствах. Остальные чипы включают в себя USB концентратор GL852G и аудио DIO2133. Если вы хотите взломать плату, вам понадобится последовательная консоль для подключения через 4-х контактный разъем находящийся снизу слева, это видно на фото выше.

На обратной стороне процессорной платы есть только слот micro SD карт и 1.5 Гб оперативной память, что дает нам в общем 3 Гб. Мы также можем видеть дополнительное охлаждение в виде толстой металлической пластины на нижней части корпуса.

Плата тюнера S2&T2_R848_REV1.2 выглядит очень похожей на плату тюнера KI Plus, но только обновленной версии с Revision 1.0 до Revision 1.2 и с некоторыми функциями DVB-C/T/T2 + DVB-S/S2 демодулятора Availink AVL6862TA, они поменяли чип тюнера Rafael Micro R848 на модель R912, которая пока не имеет документации на веб сайте Rafael Micro.
