chromecast hdcp

Objective: Company in May 2015 to do a hardware class products, using SOC (CPU+DSP) chip solution to do a high-definition conference room terminal, in addition to meeting functions, need to have multi-channel wireless screen function. Project from May, after building a team, research and development, production, testing, to January 2016 to complete a period of functional and trial production, during a lot of difficulties and twists and turns, is divided into a series to do the next review

What is Chromecast? what function does Chromecast have? Chromecast is the new connection device that Google released on July 25, 2013. The device runs a simplified version of the chrome operating system, which can be plugged into the TV HDMI interface. In the same WiFi environment, users can push a YouTube video broadcast on a cell phone or tablet to the TV via

HDCP (high-bandwidth Digital content Protection): High bandwidth Digital content protection technology. HDTV (high-definition TV) era is coming, in order to adapt to high-definition TV high bandwidth, there are HDMI. HDMI is a high-definition Digital interface standard that provides high bandwidth, lossless transmission of digital video and audio signals. In order to ensure that the HDMI or DVI transmission of high-definition signals will not be illeg

official support for Chromecast. In this way, developers only need to use the Google Cast SDK to integrate Chromecast into existing mobile or Web applications and publish it on the Google Cast developer console, this allows users to control the content displayed on large devices, such as televisions, through smartphones and tablets. For the brand new Google Drive Android API, Google said that in addition

connections.Patent license FeeUnfortunately, the HDMI interface is not an open standard. Manufacturers must pay royalties to the HDMI Standard Development Association in exchange for a production license. But this royalties is not cheap, pay 1 a yearThe $5000 license fee, and the darker one, is a $0.15 license fee for each HDMI interface that is produced. Only in this way can the manufacturer identify the HDMI-enabled logo in its own product and user manual. If the manufacturer is already a mem

HPD (Hot Plug detection) is designed for hot swapping in a pair of HDMI connections. Simply put, when the sender accesses the receiver, the receiver responds to the HPD signal to the sender, and then the sender starts the DDC channel to read the edid information of the receiver, then perform HDCP interaction. If both parties have successfully authenticated, the video and audio will work normally. Otherwise, the connection will fail and different syste

digital signals. Compatible analog signal does not mean that analog signal interface D-sub interface can be connected to the Dvi-i interface, but must be through a conversion connector to use, the general use of this interface card will have the relevant conversion connectors. When the dvi-i to the VGA, is played the role of Dvi-a, when Dvi-i dvi-d, only played the role of Dvi-d. In addition, the joint that is actually making the second set of DVI paths is sometimes called DVI-DL (dual link).

If you want to work with an existing PDF document, you can use another Nodejs project--scissors.5.log.ioLog.io is a real-time log monitoring project based on Nodejs development, accessed in a browser. It is important to note that Log.io only monitors log changes and does not store logs, but this does not matter, just know which machine the logs are stored on.Log.io uses the Socket.io library to send activity reports, and as with other monitoring tools, Log.io

HDMI chips are divided into transmitter and receiver if they are separated independently. The typical ep901 is an HDMI receiver integrated with the HDCP engine and digital audio decoder. Its HDCP is read and verified by the HDMI user, and it is on the slave side. The above is an internal chart of ep901, which is integrated with the HDCP engine to communicate w

Simply put, when the sending end is connected to the receiving end, the receiver will respond to the HPD signal to the sender, and then the sender will start the DDC channel, and read the received EDID information, and then HDCP interaction, if the two sides of the successful authentication, then the video, audio normal work, or join failure, differe

Since the release of the HDMI standard a few years ago, it has been widely used. To stick the HDMI logo, all HDMI products must pass the HDMI compliance test (hdmi ct ). To save time and money, consumers should test their HDMI products in advance before sending them to the authorized test center (ATC) for authentication. Based on the numerous pre-testing experience in the hdmi ct lab of simulator, this article discusses the most common system design problems that cause products to fail to pass t

run. It took me several hours to run the graph package update program in Gnome. This may be because the process requires a total of 375 MB of memory, seriously exceeding the available physical memory. Most of the time is spent waiting for the disk to be switched, just like the Emacs on VAX.The lesson is that the available memory will be the biggest weakness on the PS3. Close unnecessary services as soon as possible. Use xterm to replace gnome terminals. If you need multiple windows, run screen

memory will be the biggest weakness on the PS3. Close unnecessary services as soon as possible. Use xterm to replace gnome terminals. If you need multiple windows, run screen instead of multiple xterms. Show options If you are just playing games, you don't have to worry too much about these issues. However, if you need to view the display result during running, you need to consider the display option. The quality of the HDMI output of the PS3 is the best. If you have a computer monitor, the H

The project name registered by ddwg is digital visual interface (DVI ). The details of these interfaces are different. They are displayed in terms of the connected device structure and the monitor or video card calibration. However, they all trust tmds so that these

Transfer without delay Because Whdi technology provides enough wireless bandwidth, without compressing the way to transmit, save the video in the compression and decompression process of time spent, so can ensure that the transmission of film and television frequency is completely without delay. Resolution up to 1080P Whdi techno
