If you are looking for replacement tv remotes there are several to choose from. The easiest thing to do is to purchase a universal remote control from any local appliance store.
Remote controls are designed to operate with specific devices. Normally, a television remote control will not have the buttons to operate a DVD player. However, some manufacturers have television remote controls with DVD controls built in and a player from the same manufacturer can be controlled by the same remote. In addition, there are several third party remote controls that can be programmed to operate a wide variety of devices allowing one control to operate several different pieces of equipment.
The majority of televisions have some very basic controls on the television itself but they are normally limited to power, volume and channel change. There are often two buttons marked "up" and "down" with a mode button next to them. Pressing the mode button may allow a channel change mode although not all of them have the facility. Local controls on a television have become less important as the facilities offered by the remote have increased. We expect to be able to operate and set up a television from our armchairs. Manufacturers have responded by improving hand controls and removing controls from the television. It certainly means a more convenient control method but makes the television largely useless if the remote is mislaid. Until users demand full controls built into the television, manufacturers are very unlikely to increase the controls on the television itself.

Remote controls for televisions are so commonplace now that it's hard to imagine televisions without them. Many televisions today need a remote control to perform much of the configuration functions so they are a vital part of the television. There was a time when televisions didn't have remote controls of any time. It was during the 1970s that the very first remote controls were introduced. Before that time, a handful of channels could be selected using mechanical switching so remote controls weren't an option. As tuning became fully electronic, some very basic remote controls were included on some larger televisions. The very first remotes used a single button to scroll through the channels. Although some used infra red, most were ultra sonic, emitting sound pulses in excess of 30KHz (the limit of hearing is around 18 - 20Khz). Infra red remote controls were introduced during the 1980s and since then, have grown in complexity to become the full function systems we know today.
Most infra-red remote controls operate in the region of 36KHz - 40KHz although some are in the 50Hz region or higher.
