信号源及具有该信号源的电视机Signal source and TV with this signal source

技术领域technical field

本实用新型涉及一种信号源及具有该信号源的电视机，特别是涉及一种追时可录信号源及具有该信号源的电视机。The utility model relates to a signal source and a television set with the signal source, in particular to a time-tracking recordable signal source and a television set with the signal source.

背景技术Background technique

目前，被广泛使用的多为接收模拟信号的电视机，在数字电视到来的时代，大多是通过外部设备，如，机顶盒、DVD、DVB(Digital VideoBroadcasting，数字视频广播，一种国际承认的数字电视公开标准)，将数字信号转换为模拟信号后输出给电视机进行显示，例如，机顶盒将数字信号接收后转换成A/V(标准视频信号)接口信号或Y、U、V(模拟分量视频信号)等接口信号，并将转换后的低显示分辨率模拟信号输出给电视机，如图1所示，电视机通过A/V端口分别接驳DVD机顶盒、DVB机顶盒、IP电视机顶盒，但此种构架，每个机顶盒都需要独立电源对其进行供电，同时，每个机顶盒还需要独立的遥控器分别对其进行控制，而这种机顶盒输出给电视机的信号还是模拟的、分辨率很低的图像。同时由于外部设备种类多，这些设备间有许多资源重复，如：每个机器都要电源，每台设备都需一个遥控器，每个产品都有数量不等、颜色不同的输出端子，这样就造成了外部连线复杂，安装、使用极不方便而且占空间，使用不同设备都需重新连一次线头。同时，多个遥控器也不便保存、操作。用户增加一个新设备，必需是完整的机器，因而用户综合使用成本偏高，同时各设备输出无规范，同类产品接口、性能差异大。At present, most of the TVs that receive analog signals are widely used. In the era of the arrival of digital TV, most of them use external equipment, such as set-top boxes, DVD, DVB (Digital Video Broadcasting, digital video broadcasting, an internationally recognized digital TV open standard), convert the digital signal into an analog signal and output it to the TV for display, for example, the set-top box converts the digital signal into an A/V (standard video signal) interface signal or Y, U, V (analog component video signal) ) and other interface signals, and output the converted low display resolution analog signal to the TV, as shown in Figure 1, the TV is respectively connected to the DVD set-top box, DVB set-top box, and IP TV set-top box through the A/V port, but this kind of structure, each set-top box needs an independent power supply to power it, and at the same time, each set-top box also needs an independent remote control to control it separately, and the signal output by this set-top box to the TV is still analog and has a very low resolution image. At the same time, due to the variety of external devices, many resources are duplicated among these devices. For example, each machine needs a power supply, each device needs a remote control, and each product has output terminals with different numbers and colors. The external connection is complicated, the installation and use are extremely inconvenient and take up space, and the wires need to be reconnected once when using different devices. Simultaneously, it is inconvenient to store and operate multiple remote controllers. When a user adds a new device, it must be a complete machine, so the comprehensive use cost of the user is relatively high. At the same time, the output of each device is not standardized, and the interface and performance of similar products vary greatly.

另一方面，一些昂贵的高端的数字电视机，具有高分辨率(1080P、1080i、720P)的显示模式，外部设备需要通过种类繁多的接口(VGA、DVI、HDMI等)与其配接。由于电视机本身接口种类繁多，使得外部配套产品，如：机顶盒的输出模式也各式各样，往往机顶盒的输出信号也无法确保将高端电视机的图像质量效果发挥至极致。On the other hand, some expensive high-end digital TVs have high-resolution (1080P, 1080i, 720P) display modes, and external devices need to be connected to them through various interfaces (VGA, DVI, HDMI, etc.). Due to the wide variety of TV interfaces, external supporting products, such as set-top boxes, also have various output modes, and often the output signals of set-top boxes cannot ensure that the image quality of high-end TVs can be maximized.

现有技术中，也有将DVD、DVB、IP电视机顶盒内置入电视机的组合式电视机。例如中国第200420109717.1号实用新型专利，公开了一种电视数字视频光碟播放一体化机，其通过将数字视频光碟DVD播放功能内置于电视机中，使得电视机既可以收看电视节目，又能播放数字视频光碟DVD。又如中国第200520115859.3号实用新型专利，公开了一种可录IP电视一体机，其将IP电视机顶盒内置到液晶电视中。然而，在上述组合式电视机的内部，DVD、DVB、IP电视机顶盒是采用不同的接口电路连接电视机的机芯电路。各种接口的标准并不统一，也不具有扩展升级功能，很难增加新的数字节目接收源。并且不同的接口类型导致了现有系统升级也比较困难，更重要的是无法适应不同地区的加密电视接收，无法满足各个地区、各个运营商之间可能不同的信息流要求。由于将某一种特定功能与主机做成整机，破坏了主机的标准化，同时，特定功能还可能不是所有客户所需要的。此类机型一般为某一类特殊客户群体定制，用于特定场合，而非大众化需求，产品不能全面推广。这类组合式电视机由于组合模块之间的差异，导致产品规格不一、不易实现行业标准化，较难在行业内进行相关产品的配套生产，因此生产成本较高、配套产品不规范。In the prior art, there is also a combined TV set in which DVD, DVB, and IP TV set-top boxes are built into the TV set. For example, China's utility model patent No. 200420109717.1 discloses a TV digital video disc playback integrated machine, which integrates the digital video disc DVD playback function into the TV, so that the TV can not only watch TV programs, but also play digital video. Video disc DVD. Another example is the utility model patent No. 200520115859.3 of China, which discloses a recordable IP TV all-in-one machine, in which the IP TV set-top box is built into the LCD TV. However, in the above-mentioned combination TV set, DVD, DVB, and IP TV set-top boxes use different interface circuits to connect to the core circuits of the TV set. The standards of various interfaces are not unified, and there is no expansion and upgrade function, so it is difficult to add new digital program receiving sources. Moreover, different interface types make it difficult to upgrade the existing system. More importantly, it cannot adapt to encrypted TV reception in different regions, and cannot meet the information flow requirements that may vary between regions and operators. Since a specific function is integrated with the host, the standardization of the host is destroyed, and at the same time, the specific function may not be required by all customers. Such models are generally customized for a certain type of special customer group and used for specific occasions rather than popular needs, and the products cannot be fully promoted. Due to the differences between the combined modules of this type of combined TV, the product specifications are different, it is difficult to achieve industry standardization, and it is difficult to carry out supporting production of related products in the industry, so the production cost is high and the supporting products are not standardized.

随着数字化技术的发展，目前，DVD、DVB、IP电视机顶盒等设备内部，对于音频、视频信号的读出、解压缩等处理都已完全数字化，而且技术标准规范。针对数字电视的数字音视频标准接口HDMI已经在全球推广普及，这样，在这些设备与数字电视之间不再需要传送模拟信号，而直接传输标准的音频、视频数字信号将是大势所趋。With the development of digital technology, at present, DVD, DVB, IP TV set-top box and other equipment have completely digitalized the reading and decompression of audio and video signals, and the technical standards are standardized. The digital audio and video standard interface HDMI for digital TV has been promoted and popularized all over the world. In this way, it is no longer necessary to transmit analog signals between these devices and digital TV, and it will be the general trend to directly transmit standard audio and video digital signals.

同时，随着用户对电视机功能要求的增多，一种可以追时可录的机顶盒逐渐流行起来，用户可使用该机顶盒定时录制想要观看的电视机节目，但该机顶盒同样需要独立电源，独立遥控，这种机顶盒既浪费资源，又操作不便。At the same time, with the increase in user requirements for TV functions, a set-top box that can track time and record has gradually become popular. Users can use this set-top box to regularly record the TV programs they want to watch, but this set-top box also needs an independent power supply. Remote control, this kind of set-top box not only wastes resources, but also is inconvenient to operate.

为了克服现有技术的不足之处，也为了适应数字电视技术不断发展的趋势，有必要提供一种符合数字电视标准、具有追时可录功能，适配范围广，且节约资源、操作方便的信号源及具有该信号源的电视机。In order to overcome the deficiencies of the existing technology, and to adapt to the continuous development trend of digital TV technology, it is necessary to provide a digital TV standard, with the function of tracking and recording, a wide range of adaptation, resource saving, and easy operation. source and a TV with that source.
